Installing on OpenShift Container Platform
Installing ManageIQ
ManageIQ can be installed on OpenShift Container Platform in a few steps.
This procedure uses a template to deploy a multi-pod ManageIQ appliance with the database stored in a persistent volume on OpenShift Container Platform. It provides a step-by-step setup, including cluster administrative tasks as well as information and commands for the application developer using the deployment.
The ultimate goal of the deployment is to be able to deconstruct the ManageIQ appliance into several containers running on a pod or a series of pods.
Running the ManageIQ appliance in a series of pods has several advantages. For example, running each worker in a separate pod allows OpenShift Container Platform to manage worker processes and reduce worker memory consumption. OpenShift can also easily scale workers by adding or removing pods, and perform upgrades by using images.
There are two options for installing ManageIQ on OpenShift:
-
During OpenShift Container Platform 3.7 installation:
- When you install OpenShift Container Platform 3.7, you have the option to install ManageIQ inside OpenShift at the time. This method leverages the Ansible installer to run and deploy the ManageIQ template, instead of building the environment manually. See the OpenShift Container Platform 3.7 Release Notes for details.
-
Manual install on an existing OpenShift Container Platform environment:
- Deploy ManageIQ pods using the ManageIQ template (.yaml file). This is the method described in this guide.
After deployment, you can configure the ManageIQ environment to use any external authentication configurations supported by ManageIQ.
Prerequisites
To successfully deploy a ManageIQ appliance on OpenShift Container Platform, you need a functioning OpenShift Container Platform 3.7 install with the following configured:
-
NFS or other compatible volume provider
-
A
cluster-adminuser -
A regular user (such as an application developer)
Cluster Sizing
To avoid deployment failures due to resource starvation, Red Hat recommends the following minimum cluster size for a test environment:
-
1 master node with at least 8 vCPUs and 12GB RAM
-
2 schedulable nodes with at least 4 vCPUs and 8GB RAM
-
25GB storage for ManageIQ physical volume use
These recommendations assume ManageIQ is the only application running on this cluster. Alternatively, you can provision an infrastructure node to run registry, metrics, router, and logging pods.
Each ManageIQ application pod will consume at least 3GB RAM on initial deployment (without providers added). RAM consumption increases depending on the appliance use. For example, after adding providers, expect higher resource consumption.
Limitations
The following limitations exist when deploying this version of ManageIQ on OpenShift Container Platform 3.7:
-
This configuration cannot run on public OpenShift (OpenShift.io and OpenShift Dedicated environments) because of necessary privileges
-
The Embedded Ansible pod must run as a privileged pod
-
OpenShift cannot independently scale workers
-
A highly available database is not supported in PostgreSQL pods
Templates and Images
Preparing to Deploy ManageIQ
To prepare for deploying the ManageIQ appliance to OpenShift Container Platform, create a project, configure security contexts, and create persistent storage.
-
As a regular user, log in to OpenShift:
$ oc login -u <user> -p <password> -
Create a project with your desired parameters. The project name (
<your_project>in this example) is mandatory, but<description>and<display_name>are optional:$ oc new-project <your_project> \ --description="<description>" \ --display-name="<display_name>" -
As the admin user, configure security context constraints (SCCs) for your OpenShift service accounts:
-
Add the
cfme-anyuidservice account to theanyuidSCC:$ oc adm policy add-scc-to-user anyuid system:serviceaccount:<your-project>:cfme-anyuid -
Add the
cfme-orchestratorservice account to theanyuidSCC:$ oc adm policy add-scc-to-user anyuid system:serviceaccount:<your-project>:cfme-orchestrator -
Add the
cfme-httpdservice account to theanyuidSCC:$ oc adm policy add-scc-to-user anyuid system:serviceaccount:<your-project>:cfme-httpd -
Add the
cfme-privilegedservice account to theprivilegedSCC:$ oc adm policy add-scc-to-user privileged system:serviceaccount:<your-project>:cfme-privileged
-
-
Verify the SCCs are added correctly to the service accounts and project:
$ oc describe scc anyuid | grep Users Users: system:serviceaccount:<your-project>:cfme-anyuid,system:serviceaccount:<your-project>:cfme-httpd,system:serviceaccount:<your-project>:cfme-orchestrator $ oc describe scc privileged | grep Users Users: system:admin,system:serviceaccount:openshift-infra:build-controller,system:serviceaccount:management-infra:management-admin,system:serviceaccount:management-infra:inspector-admin,system:serviceaccount:logging:aggregated-logging-fluentd,system:serviceaccount:<your-project>:cfme-privilegedFor more information on SCCs, see the [OpenShift documentation](https://docs.openshift.com/container-platform/3.7/admin_guide/manage_scc.html). -
As the admin user, add the
httpd-configmap-generatorservice account to thehttpd-scc-sysadminSCC before the Httpd Configmap Generator can run.Users: system:serviceaccount:<your-namespace>:httpd-configmap-generator -
Add the
viewandeditroles to thecfme-orchestratorservice account:$ oc policy add-role-to-user view system:serviceaccount:<your-project>:cfme-orchestrator -n <your-project> $ oc policy add-role-to-user edit system:serviceaccount:<your-project>:cfme-orchestrator -n <your-project> -
As the admin user, prepare persistent storage for the deployment. (Skip this step if you have already configured persistent storage.)
A basic ManageIQ deployment needs at least two persistent volumes (PVs) to store ManageIQ data. As the admin user, create two persistent volumes: one to host the ManageIQ PostgreSQL database, and one to host the application data.
Example NFS-backed volume templates are provided by
cfme-pv-db-example.yamlandcfme-pv-server-example.yaml, available from the image stream or repository configured in Templates and Images.For NFS-backed volumes, ensure your NFS server firewall is configured to allow traffic on port 2049 (TCP) from the OpenShift cluster. Red Hat recommends setting permissions for the pv-app (privileged pod volume) as 777, uid/gid 0 (owned by root). For more information on configuring persistent storage in OpenShift Container Platform, see the [OpenShift Container Platform Installation and Configuration](https://access.redhat.com/documentation/en-us/openshift_container_platform/3.7/html-single/installation_and_configuration/#configuring-persistent-storage) guide.-
Configure your NFS server host details within these files, and edit any other settings needed to match your environment.
-
Create the two persistent volumes:
$ oc create -f cfme-pv-db-example.yaml $ oc create -f cfme-pv-server-example.yaml -
Process the templates, editing the NFS_HOST parameter (mandatory) and any other parameters:
$ oc process cfme-pv-db-example.yaml -p NFS_HOST=nfs.example.com | oc create -f -Alternatively, you can create the two persistent volumes and process the templates in a single command:
$ oc process cfme-pv-server-example.yaml -p NFS_HOST=nfs.example.com | oc create -f -There are three parameters required to process the template. Only NFS\_HOST is required, PV\_SIZE and BASE\_PATH contain defaults that do not need editing unless desired: - PV\_SIZE - Defaults to the recommended PV size for the App/DB template (5Gi/15Gi respectively) - BASE\_PATH - Defaults to /exports - NFS\_HOST - No Default - Hostname or IP address of the NFS server -
Verify the persistent volumes were created successfully:
$ oc get pv NAME CAPACITY ACCESSMODES RECLAIMPOLICY STATUS CLAIM STORAGECLASS REASON AGE cfme-app 5Gi RWO Retain Available 16s cfme-db 15Gi RWO Retain Available 49sRed Hat recommends validating NFS share connectivity from an OpenShift node before attempting a deployment.
-
-
Increase the maximum number of imported images on ImageStream.
By default, OpenShift Container Platform can import five tags per image stream, but the ManageIQ repositories contain more than five images for deployments.
You can modify this setting on the master node at
/etc/origin/master/master-config.yamlso OpenShift can import additional images.-
Add the following at the end of the
/etc/origin/master/master-config.yamlfile:... imagePolicyConfig: maxImagesBulkImportedPerRepository: 100 -
Restart the master service:
$ systemctl restart atomic-openshift-master
-
-
On each OpenShift node, persistently enable the
container_manage_cgroupSELinux boolean to allow container processes to make changes to the cgroup configuration:# setsebool -P container_manage_cgroup on
Deploying the ManageIQ Appliance
To deploy the appliance on OpenShift Container Platform, create the ManageIQ template and verify it is available in your project.
-
As a regular user, create the ManageIQ template:
$ oc create -f cfme-template.yaml template "cloudforms" created -
Verify the template is available with your project:
$ oc get templates NAME DESCRIPTION PARAMETERS OBJECTS cloudforms CloudForms appliance with persistent storage 18 (1 blank) 12 -
(Optional) Customize the template’s deployment parameters. Use the following command to see the available parameters and descriptions:
$ oc process --parameters -n <your-project> cloudformsTo customize the deployment configuration parameters, run:
$ oc edit dc/<deployconfig_name> -
To deploy ManageIQ from template using default settings, run:
$ oc new-app --template=cloudformsAlternatively, to deploy ManageIQ from a template using customized settings, add the
-poption and the desired parameters to the command. For example:$ oc new-app --template=cloudforms -p DATABASE_VOLUME_CAPACITY=2Gi,POSTGRESQL_MEM_LIMIT=4Gi,APPLICATION_DOMAIN=hostnameThe `APPLICATION_DOMAIN` parameter specifies the hostname used to reach the ManageIQ application, which eventually constructs the route to the ManageIQ pod. If you do not specify the `APPLICATION_DOMAIN` parameter, the ManageIQ application will not be accessible after the deployment; however, this can be fixed by changing the route. For more information on OpenShift template parameters, see the [OpenShift Container Platform Developer Guide](https://access.redhat.com/documentation/en-us/openshift_container_platform/3.7/html-single/developer_guide/#dev-guide-templates).
Deploying the ManageIQ Appliance Using an External Database
Before attempting to deploy ManageIQ using an external database deployment, ensure the following conditions are satisfied:
-
Your OpenShift cluster can access the external PostgreSQL server
-
The ManageIQ user, password, and role have been created on the external PostgreSQL server
-
The intended ManageIQ database is created, and ownership has been assigned to the ManageIQ user
To deploy the appliance:
-
Import the ManageIQ external database template:
$ oc create -f templates/cfme-template-ext-db.yaml -
Launch the deployment with the following command. The database server IP address is required, and the other settings must match your remote PostgreSQL server.
$ oc new-app --template=cloudforms-ext-db -p DATABASE_IP=<server_ip> -p DATABASE_USER=<user> -p DATABASE_PASSWORD=<password> -p DATABASE_NAME=<database_name>
Verifying the Configuration
Verify the deployment was successful by running the following commands as a regular user under the ManageIQ project:
-
Confirm the ManageIQ pod is bound to the correct security context constraints:
-
List and obtain the name of the
cfme-apppod:$ oc get pod NAME READY STATUS RESTARTS AGE cloudforms-0 1/1 Running 0 4m httpd-1-w486v 1/1 Running 0 4m memcached-1-4xtjc 1/1 Running 0 4m postgresql-1-n5tm6 1/1 Running 0 4m -
Export the configuration of the pod:
$ oc export pod <cfme_pod_name> -
Examine the output to verify that
openshift.io/scchas the valueanyuid:... metadata: annotations: openshift.io/scc: anyuid ...
-
-
Verify the persistent volumes are attached to the
postgresqlandcfme-apppods:$ oc volume pods --all pods/postgresql-1-437jg pvc/cfme-pgdb-claim (allocated 2GiB) as cfme-pgdb-volume mounted at /var/lib/pgsql/data secret/default-token-2se06 as default-token-2se06 mounted at /var/run/secrets/kubernetes.io/serviceaccount pods/cfme-1-s3bnp pvc/cfme (allocated 2GiB) as cfme-app-volume mounted at /persistent secret/default-token-9q4ge as default-token-9q4ge mounted at /var/run/secrets/kubernetes.io/serviceaccount -
Check the readiness of the ManageIQ pod:
Allow approximately five minutes once pods are in running state for ManageIQ to start responding on HTTPS.$ oc describe pods <cfme_pod_name> ... Conditions: Type Status Ready True Volumes: ... -
After you have successfully validated your ManageIQ deployment, disable automatic image change triggers to prevent unintended upgrades.
By default, on initial deployments the automatic image change trigger is enabled. This could potentially start an unintended upgrade on a deployment if a newer image is found in the ImageStream.
Disable the automatic image change triggers for ManageIQ deployment configurations (DCs) on each project with the following commands:
$ oc set triggers dc --manual -l app=cloudforms deploymentconfig "memcached" updated deploymentconfig "postgresql" updated $ oc set triggers dc --from-config --auto -l app=cloudforms deploymentconfig "memcached" updated deploymentconfig "postgresql" updatedThe configuration change trigger is kept enabled; to have full control of your deployments, you can alternatively turn it off. See the [OpenShift Container Platform Developer Guide](https://access.redhat.com/documentation/en-us/openshift_container_platform/3.7/html-single/developer_guide/#dev-guide-triggering-builds) for more information on deployment triggers.
Logging into ManageIQ
As part of the deployment, a route to the ManageIQ appliance is created for HTTPS access. Once the pods have been successfully deployed, you can log into ManageIQ.
You can obtain the ManageIQ host address from the project in the OpenShift user interface, or by opening a shell on the pod and getting the route information.
-
To open a shell on the pod, run:
$ oc rsh <pod_name> bash -l -
Get the route information:
$ oc get routes NAME HOST/PORT PATH SERVICE TERMINATION LABELS cloudforms cfme.apps.e2e.example.com cloudforms:443-tcp passthrough app=cloudforms -
Navigate to the reported URL/host on a web browser (in this example,
cfme.apps.e2e.example.com). -
Enter the default ManageIQ credentials (Username: admin | Password: smartvm) for the initial login.
-
Click Login.
Configuring External Authentication to ManageIQ
After installing ManageIQ, configure external authentication by updating the httpd-auth-configs configuration map on the httpd pod to include all necessary configuration files and certificates.
Upon startup, the httpd pod overlays its files with the ones specified in the auth-configuration.conf file in the configuration map. This is done by the initialize-httpd-auth service that runs before httpd.
You can automatically generate an updated configuration map by running the httpd-configmap-generator tool in its own pod using the steps in Configuring External Authentication Automatically (recommended).
Alternatively, you can define the configuration map manually using the commands in Defining the Configuration Map Manually.
Configuring External Authentication Automatically
To automatically generate an authconfig map, run the httpd_configmap_generator tool with your desired parameters:
$ httpd_configmap_generator <command_or_authentication_type>
Note:
Run httpd_configmap_generator --help or see External Authentication Configuration Map Settings
for configuration map parameters.
Supported Authentication Types
The following authentication types can be configured with the httpd_configmap_generator tool to configure external authentication.
For usage, run:
$ httpd_configmap_generator <auth-type> --help
| auth-type | Identity Provider/Environment |
| active-directory | Active Directory domain realm join |
| ipa | IPA, IPA 2-factor authentication, IPA/AD Trust |
| ldap | LDAP directories |
| saml | Keycloak, Red Hat SSO |
Supported Authentication Types
Updating an authconfig Map
With the update subcommand, you can add file(s) to the configuration map to specify file ownership and permissions. The --add-file option can be specified multiple times (once per file) to add files to a configuration map.
Supported file specifications for the --add-file option are:
--add-file=file-path
--add-file=source-file-path,target-file-path
--add-file=source-file-path,target-file-path,file-permission
--add-file=file-url,target-file-path,file-permission
When entering file specifications, file-url is an HTTP URL and file-permission can be specified as mode:owner:group.
Adding files by specifying paths.
The file ownership and permissions are based on the files specified. For example:
$ httpd_configmap_generator update \
--input=/tmp/original-auth-configmap.yaml \
--add-file=/etc/openldap/cacerts/primary-directory-cert.pem \
--add-file=/etc/openldap/cacerts/seconday-directory-cert.pem \
--output=/tmp/updated-auth-configmap.yaml
Adding target files from different source directories.
$ httpd_configmap_generator update \
--input=/tmp/original-auth-configmap.yaml \
--add-file=/tmp/uploaded-cert1,/etc/openldap/cacerts/primary-directory-cert.pem \
--add-file=/tmp/uploaded-cert2,/etc/openldap/cacerts/seconday-directory-cert.pem \
--output=/tmp/updated-auth-configmap.yaml
The file ownership and permissions are based on the source files specified; in this case the ownership and permissions of the
/tmp/uploaded-cert1 and /tmp/uploaded-cert2 files will be used.
Adding a target file with user-specified ownership and mode.
$ httpd_configmap_generator update \
--input=/tmp/original-auth-configmap.yaml \
--add-file=/tmp/secondary-keytab,/etc/http2.keytab,600:apache:root \
--output=/tmp/updated-auth-configmap.yaml
Adding files by URL.
$ httpd_configmap_generator update \
--input=/tmp/original-auth-configmap.yaml \
--add-file=http://aab-keycloak:8080/auth/realms/testrealm/protocol/saml/description,/etc/httpd/saml2/idp-metadata.xml,644:root:root \
--output=/tmp/updated-auth-configmap.yaml
When downloading a file by URL, a target file path and file ownership and mode must be specified.
Exporting a File from an authconfig Map
With the export subcommand, you can export a file from the configuration map. For example, to extract the sssd.conf file from the authconfig map:
$ httpd_configmap_generator export \
--input=/tmp/external-ipa.yaml \
--file=/etc/sssd/sssd.conf \
--output=/tmp/sssd.conf
Building the httpd_configmap_generator in a Container
The httpd_configmap_generator is the container for configuring external authentication for the httpd auth pod. It is based on the auth httpd container and generates the httpd authconfig map needed to enable external authentication.
Two templates are required to run the httpd-configmap-generator application (httpd-configmap-generator-htmplate.yaml and httpd-scc-sysadmin.yaml), which are available from the Red Hat Container Catalog.
Preparing to Deploy the httpd-configmap-generator Application
-
To obtain the latest
cfme-httpd-configmap-generatorimage from the Red Hat Container Catalog, run:$ oc import-image my-cloudforms46/cfme-httpd-configmap-generator --from=registry.access.redhat.com/cloudforms46/cfme-httpd-configmap-generator --confirm -
The
httpd-configmap-generatorservice account must be added to thehttpd-scc-sysadminsecurity context constraints (SCC) before thehttpd-configmap-generatorcan run. To edit the SCC, log in to OpenShift as an admin user:$ oc login -u <user> -p <password> -
Create the
httpd-scc-sysadminSCC:$ oc create -f templates/httpd-scc-sysadmin.yaml -
Add the
httpd-configmap-generatorservice account to thehttpd-scc-sysadminSCC:$ oc adm policy add-scc-to-user httpd-scc-sysadmin system:serviceaccount:<your-namespace>:httpd-configmap-generator -
Verify that the
httpd-configmap-generatorservice account is now included in thehttpd-scc-sysadminSCC:$ oc describe scc httpd-scc-sysadmin | grep Users Users: system:serviceaccount:<your-namespace>:httpd-configmap-generator
Deploying the httpd-configmap-generator Application
-
As a regular user, run:
$ oc create -f httpd-configmap-generator-template.yaml -
Verify the template is available with your project:
$ oc get templates NAME DESCRIPTION PARAMETERS OBJECTS httpd-configmap-generator Httpd Configmap Generator 6 (all set) 3 -
Deploy the
httpd-configmap-generator:$ oc new-app --template=httpd-configmap-generator -
Check the readiness of the
httpd-configmap-generator:$ oc get pods NAME READY STATUS RESTARTS AGE httpd-configmap-generator-1-txc34 1/1 Running 0 1h
Getting the Pod Name
To work with the httpd-configmap-generator script in the httpd-configmap-generator pod, it is necessary to get the pod name as
follows:
$ CONFIGMAP_GENERATOR_POD=`oc get pods | grep "httpd-configmap-generator" | cut -f1 -d" "`
Example: Generating an authconfig Map for External Authentication Against IPA
The following example shows how to generate a configuration map for external authentication using IPA.
-
To generate an
authconfigmap for external authentication using IPA, run:$ oc rsh $CONFIGMAP_GENERATOR_POD -- bash -c httpd_configmap_generator ipa \ --host=appliance.example.com \ --ipa-server=ipaserver.example.com \ --ipa-domain=example.com \ --ipa-realm=EXAMPLE.COM \ --ipa-principal=admin \ --ipa-password=smartvm1 \ -o /tmp/external-ipa.yamlNote:
--hostmust be the DNS of the application exposing thehttpdpod, for example ${APPLICATION_DOMAIN}. -
Copy the new
authconfigmap back locally:$ oc cp $CONFIGMAP_GENERATOR_POD:/tmp/external-ipa.yaml ./external-ipa.yaml -
Apply the new configuration map to the
httpdpod, and then redeploy it to take effect:$ oc replace configmaps httpd-auth-configs --filename ./external-ipa.yaml
To generate a new authconfig map, redeploy the httpd-configmap-generator pod first to get a clean environment before
running the httpd-configmap-generator tool.
If additional configuration is needed, you can configure the configuration map manually using the steps in Defining the Configuration Map Manually. See External Authentication Configuration Map Settings for configuration map parameters.
Cleaning up
After generating an authconfig map, the httpd-configmap-generator pod can be scaled down, or deleted if no longer needed.
To scale down the pod, run:
$ oc scale dc httpd-configmap-generator --replicas=0
To delete the pod, run:
$ oc delete all -l app=httpd-configmap-generator
$ oc delete pods -l app=httpd-configmap-generator
Defining the Configuration Map Manually
The authconfig map can be defined and customized in the httpd pod as follows:
$ oc edit configmaps httpd-auth-configs
Alternatively, you can replace the httpd-auth-configs file with an externally generated and edited configuration file as follows:
$ oc replace configmaps httpd-auth-configs --filename external-auth-configmap.yaml
After editing the configuration map, redeploy the httpd pod for the new authentication configuration to take effect.
Managing ManageIQ with OpenShift
This section includes common tasks to manage your ManageIQ deployment from OpenShift.
Configuring Custom SSL Certificates for ManageIQ
By default, the route that is deployed as part of the template uses edge termination and the certificates that OpenShift is installed with. It is possible to change this in the OpenShift UI with the following steps:
-
Browse to menu: Applications > Routes.
-
Click on the route named httpd, then select menu: Actions > Edit.
-
Scroll down to the Certificates section. Here you can upload or paste the required certificate files.
-
Click Save.
Scaling ManageIQ Appliances
StatefulSets in OpenShift manage the deployment and scaling of a set of pods (in this case, ManageIQ appliances). StatefulSets ensure ordering that applications will come up by providing unique identities for pods.
Important:
Each new replica (server) consumes a physical volume. Before scaling, ensure you have enough physical volumes available to scale.
The following example shows scaling using StatefulSets:
Example: Scaling to two replicas.
$ oc scale statefulset cloudforms --replicas=2
statefulset "cloudforms" scaled
$ oc get pods
NAME READY STATUS RESTARTS AGE
cloudforms-0 1/1 Running 0 34m
cloudforms-1 1/1 Running 0 5m
memcached-1-mzeer 1/1 Running 0 1h
postgresql-1-dufgp 1/1 Running 0 1h
The newly created replicas will join the existing ManageIQ region. Each new pod is numbered in the order it is deployed, starting with 0 and increasing sequentially. For example, replicas in a StatefulSet will be numbered cloudforms-0 cloudforms-1, and so on.
Creating a Backup
Create a persistent volume for backups using the PV backup template (cfme-pv-backup-example.yaml) in case you need to restore to a previous version.
-
Create the persistent volume for the backup:
$ oc create -f cfme-pv-backup-example.yaml -
Create the backup persistent volume claim (PVC):
$ oc create -f cfme-backup-pvc.yaml -
Verify the persistent volume claim was created:
$ oc get pvc -
Back up secrets, such as database encryption keys and credentials.
Important:
Be careful to back up secrets in a secure location.
$ oc get secret -o yaml --export=true > secrets.yaml $ oc get pvc -o yaml --export=true > pvc.yaml -
Initiate the database backup:
$ oc create -f cfme-backup-job.yaml
This step creates a container, and connects to the database pod, pg_basebackup.
Restoring to a Backup
You can restore to a database backup created in Creating a Backup using the restore template,
cfme-restore-job.yaml.
The restore job will look for cfme-backup and cfme-postgresql PVs by default, and the latest successful backup will be restored by default. If existing data is found on the cfme-postgresql volume, it will be renamed and left on the volume.
Important:
You must perform a database restore on an offline environment. All pods must be scaled down to 0, and not running.
-
Shut down all pods:
$ oc scale dc --all --replicas=0 $ oc scale statefulset --all --replicas=0 -
To initiate the database restore, create the restore template:
$ oc create -f cfme-restore-job.yaml
After the restore job is complete, you can scale the pods back up.
Updating ManageIQ
Apply package updates to your ManageIQ appliance from OpenShift Container Platform by deleting the pods and redeploying them using updated ManageIQ container images. To update your environment with a new template, follow the steps in Updating the ManageIQ Container Images and Template.
Updating the ManageIQ Container Images
To deploy new container images for ManageIQ, delete the pods, update the images, then redeploy the updated pods:
-
Delete the pods by scaling the application StatefulSets to 0 replicas:
$ oc scale statefulset cloudforms --replicas=0 $ oc scale statefulset cloudforms-backend --replicas=0 -
Patch in the new version of the images:
$ oc patch statefulset cloudforms -p '{"spec": {"template": {"spec": {"containers": [{"name": "cloudforms", "image": "registry.redhat.io/cloudforms46/cfme-openshift-app-ui:<new-version-tag>"}]}}}}' $ oc patch statefulset cloudforms-backend -p '{"spec": {"template": {"spec": {"containers": [{"name": "cloudforms", "image": "registry.redhat.io/cloudforms46/cfme-openshift-app:<new-version-tag>"}]}}}}' -
Scale the StatefulSets back to your previous values to redeploy the pods:
$ oc scale statefulset cloudforms --replicas=<old-value> $ oc scale statefulset cloudforms-backend --replicas=<old-value>
Your ManageIQ environment is now updated to use the new container images.
Updating the ManageIQ Container Images and Template
To update a ManageIQ deployment with a new template, update the container images and the template using the following steps:
-
Back up secrets, such as database encryption keys and credentials:
Important:
Be careful to back up secrets in a secure location.
$ oc export secret cloudforms-secrets > my_secrets.yml -
Delete the pods by scaling the application StatefulSets to 0 replicas:
$ oc scale statefulset cloudforms --replicas=0 $ oc scale statefulset cloudforms-backend --replicas=0 -
Apply the changes to the project, specifying the template appropriate to your environment’s database configuration.
Important:
If you customized any parameters when originally deploying the application (parameters used with the
oc new-appcommand in Deploying the ManageIQ Appliance), you must set the same values in theoc processcommand here.-
For environments using a database stored on a pod within the cluster (the default configuration), specify the ManageIQ template:
$ oc process -p APPLICATION_REPLICA_COUNT=0 -l app=cloudforms,template=cloudforms -f cfme-template.yaml | oc replace -f - -
For environments using a database external to the OpenShift cluster, specify the ManageIQ external database template:
$ oc process -p APPLICATION_REPLICA_COUNT=0 -l app=cloudforms,template=cloudforms-ext-db -f cfme-template-ext-db.yaml | oc replace -f -
-
-
Replace the secret with the
my_secrets.ymlfile you created earlier:$ oc replace -f my_secrets.yml -
Redeploy the
postgresqlpod to ensure the password from the old secret is used:$ oc rollout latest postgresql -
Scale the StatefulSets back to your previous values to redeploy the pods:
$ oc scale statefulset cloudforms --replicas=<old-value> $ oc scale statefulset cloudforms-backend --replicas=<old-value>
Your ManageIQ environment is now updated to use the new template and container images.
Uninstalling ManageIQ from a Project
If no longer needed, you can uninstall the ManageIQ pod from your project. Note the following commands do not remove SCC permissions, or the project itself.
Important:
Use this procedure if only ManageIQ exists in the project.
-
Inside the project, run the following as a regular user:
$ oc delete all --all -
Wait approximately 30 seconds for the command to process, then run:
$ oc delete pvc --all
Troubleshooting Deployment
Under normal circumstances, the deployment process takes approximately 10 minutes. If the deployment is unsuccessful, examining deployment events and pod logs can help identify any issues.
-
As a regular user, first retry the failed deployment:
$ oc get pods NAME READY STATUS RESTARTS AGE cloudforms-1-deploy 0/1 Error 0 25m memcached-1-yasfq 1/1 Running 0 24m postgresql-1-wfv59 1/1 Running 0 24m $ oc deploy cloudforms --retry Retried #1 Use 'oc logs -f dc/cloudforms' to track its progress. -
Allow a few seconds for the failed pod to get re-scheduled, then check events and logs:
$ oc describe pods <pod-name> ... Events: FirstSeen LastSeen Count From SubobjectPath Type Reason Message --------- -------- ----- ---- ------------- -------- ------ ------- 15m 15m 1 {kubelet ocp-eval-node-2.e2e.example.com} spec.containers{cloudforms} Warning Unhealthy Readiness probe failed: Get http://10.1.1.5:80/: dial tcp 10.1.1.5:80: getsockopt: connection refusedLiveness and readiness probe failures, like in the output above, indicate the pod is taking longer than expected to come online. In this case, check the pod logs.
-
As the
cfme-appcontainer issystemdbased, useoc rshinstead ofoc logsto obtain journal dumps:$ oc rsh <pod-name> journalctl -x -
Transferring all logs from the
cfme-apppod to a directory on the host for further examination can be useful for troubleshooting. Transfer the logs with theoc rsynccommand:$ oc rsync <pod-name>:/persistent/container-deploy/log \ /tmp/fail-logs/ receiving incremental file list log/ log/appliance_initialize_1477272109.log log/restore_pv_data_1477272010.log log/sync_pv_data_1477272010.log sent 72 bytes received 1881 bytes 1302.00 bytes/sec total size is 1585 speedup is 0.81
Appendix
External Authentication Configuration Map Settings
See Sample External Authentication Configuration for an example configuration map file.
The configuration map includes the following parameters:
-
auth-type The authentication type.
This parameter controls which configuration files
httpdwill load upon startup. The default isinternal. Supported values are:Value External Authentication Configuration internalApplication Based Authentication - Database, LDAP/LDAPS, Amazon. This is the default. externalIPA, IPA 2-factor authentication, IPA/AD Trust, LDAP (OpenLDAP, RHDS, Active Directory, etc.) active-directoryActive Directory domain realm join samlSAML based authentication (Keycloak, ADFS, etc.) auth-typevaluesEnabling external authentication must be done from the ManageIQ user interface; see [Configuring External Authentication](https://access.redhat.com/documentation/en-us/red_hat_cloudforms/4.7/html/managing_authentication_for_cloudforms/external_auth) in *Managing Authentication* for details. -
auth-kerberos-realms The Kerberos realms to join.
When configuring external authentication against IPA, Active Directory or LDAP, this parameter defines the Kerberos realm
httpdis configured against, such as example.com. When specifying multiple Kerberos realms, they must be separated by spaces. The default isundefined. -
auth-configuration.conf The external authentication configuration file which declares the list of files to overlay upon startup if
auth-typeis other thaninternal.Syntax for the file is as follows:
# for comments file = basename1 target_path1 permission1 file = basename2 target_path2 permission2For the files to overlay on the
httpdpod, onefiledirective is needed per file. -
basename The name of the source file in the configuration map.
-
permission (optional) By default, files are copied using the pod’s default umask, owner and group, so files are created as mode 644 owner root, group root.
permissioncan be specified as follows, reflecting the mode and ownership to set the copied files to:-
mode
-
mode:owner
-
mode:owner:group
For example:
-
755
-
640:root
-
644:root:apache
Binary files can be specified in the configuration map in their base64 encoded format with a basename having a
.base64extension. Such files are then converted back to binary as they are copied to their target path.When an
/etc/sssd/sssd.conffile is included in the configuration map, thehttpdpod automatically enables the SSSD service upon startup.
-
-
target_path The path of the file on the pod to overwrite, i.e.
/etc/sssd/sssd.conf.
