Installing the server software on Ubuntu using microk8s

You can install Rational® Test Automation Server on the Ubuntu server that has a Kubernetes environment to run functional, integration, and performance tests. Rational® Test Automation Server combines test data, test environments, and test runs and reports into a single, web-based browser for testers and non-testers.

Before you begin

You must have completed the following tasks:

About this task

As part of the installation process, you might optionally migrate user data from a previous version of the product, or restore a backup of user data from the current version of the product. You must perform different steps, depending on which version of the user data backup file you are applying during the install. For more details, see the following table:

Backed up user data from To restore
Rational® Test Automation Server V10.0.2, Fix Pack 1 or earlier Perform the step 6 and 7.
Rational® Test Automation Server V10.1.0 Perform the step 10.


  1. Log in to the Ubuntu server as a non-root user.
  2. Create a namespace to install the server software by entering the following command:
    kubectl create namespace test-system
  3. Add the repository to Helm to access the server install charts by entering the following command:
    helm repo add ibm-helm
  4. Run the following command to get the latest updates from the repository:
    helm repo update
  5. Create a secret to pull images that are used by Rational® Test Automation Server by entering the following command:
    • You must substitute {api-key} with your key for the repository.

    • You can replace the not-required@test with the administrators email address, if desired.

    kubectl create secret docker-registry \
      -n test-system \ \
      --docker-username=iamapikey \
      --docker-password={api-key} \
  6. Optional: Run the following commands to start a pod that assists you in migrating user data:
    #Retrieve the backup yaml file
    curl  -Lo ibm-rtas-prod.tgz
    #Extract the file
    tar xvf ibm-rtas-prod.tgz
    #Modify the backup yaml file with the release name for your server by replacing {my-rtas}
    sed -i 's/{{ \.Release\.Name }}/{my-rtas}/g' ibm-rtas-prod/files/import-prek8s-backup.yaml
    #Apply the backup yaml file to start the import-prek8s-backup pod
    kubectl apply -f ibm-rtas-prod/files/import-prek8s-backup.yaml -n test-system
  7. Optional: Run the following command to display the import-prek8s-backup pod's log, and then follow the instructions in the log to copy your backup file to where the pod is waiting to process it:
    kubectl logs import-prek8s-backup -n test-system

    When the user data backup is fully migrated, the import-prek8s-backup pod changes from Running to Completed state. To view the pod state you can run the kubectl get pod import-prek8s-backup -n test-system command.

    Progress can be monitored by displaying the log to check for updates. When the state of the pod is Completed, the log file displays the additional parameters that must be added to the helm install in step 8. The following is an example that shows the additional helm arguments:
    --set keycloak.keycloak.username=admin \
     --set execution.existingPostgresqlPassword=SwztX9JRO/yL9jtgioUiKMGjlsWfM7Ok \
     --set existingKeycloakPassword=jqdV7aveCa3WShkdSF/Z8hAasBupsvp6 \
     --set existingKeycloakPostgresqlPassword=pKVFQUQWRU7BJC6sKeOZIm8zCzLkbXM7 \
     --set existingOauthClientSecret=EMRpHBRurFIMB9X+nfwApnLBBpkvn8+z \
     --set existingPostgresqlPassword=8HY3nADjTZBC2lLj0i7Y7v6wHeEji9ds \
     --set existingSecretsMasterPassword=ibIPh6wGAv0IjsveOrYX1TRwo3ChvxWx \
     --set results.existingPostgresqlPassword=7X3aaAVeHxdzJ+BlFTG7G7rypzsbhd6D \
     --set rm.existingPostgresqlPassword=3uaEx5wTja+PSzvG64O1+cpO3glGAaVt \
     --set tam.existingPostgresqlPassword=7JO95keyZ/F9w5rBcXj2YZFKFf/aAK1F \
  8. Run the following commands to install the server software on your computer:
    • You must substitute the following variables value with the actual value in the command:

      • {my-rtas} with the release name that you provided for the server.

      • {my-ingress-dns-name} with the same Ingress DNS name that you used in

      • {rlks-ip-address} with the IP address of the Rational License Key Server.

      • {my-super-secret} with a password seed that you selected.

      • {namespace} with the name of the namespace that you created.

    • The password seed is used to create all other default passwords. You must store the password seed securely. The password seed is reused when you install the server software by using a backup of user data. This seed is used when restoring backup files either on the current or later versions of the server software.

    • If you migrated user data from a previous release, you must use the same {my-rtas} name that you chose then, during the install step.

    #Make sure the repository is current
    helm repo update
    helm pull --untar ibm-helm/ibm-rtas-prod --version 1.101.0
    #Install the server
    helm install {my-rtas} ibm-helm/ibm-rtas-prod -n test-system \
     --set license=accept \
     --set global.ibmRtasIngressDomain={my-ingress-dns-name} \
     --set global.rationalLicenseKeyServer=@{rlks-ip-address} \
     --set global.ibmRtasPasswordAutoGenSeed={my-super-secret} \
     --set \
     --set keycloak.keycloak.image.pullSecrets[0]
    Optionally, to enable virtual services to use the Istio Service Mesh, complete the following two steps:
    1. Add the following parameters to the helm install parameters in the preceding command before installing the server:
      --set execution.istio.enabled=true \
      --set execution.istio.clusterRoleBinding.create=true
    2. Run the following command to create the role bindings required for Istio:
      kubectl create rolebinding istio-virtualization-enabled -n {namespace} --clusterrole={my-rtas}-execution-istio-test-system --serviceaccount=test-system:{my-rtas}-execution 
      Note: When you uninstall the chart, the manually created role bindings are not deleted from the namespace.
  9. Optional: Set the following parameters, if you have installed a Jaeger operator on the cluster and you want to use it for performance and Web UI tests logs:
    --set-string execution.annotations.sidecar\\.jaegertracing\\.io/inject=true
    --set global.jaegerAgent.enabled=true
    --set global.jaegerAgent.internalHostName=localhost
    --set global.jaegerDashboard.enabled=true
    --set global.jaegerDashboard.externalURL={my-jaeger-dashboard-url}
    Note: You must substitute {my-jaeger-dashboard-url} with the URL of the Jaeger server.
  10. Optional: Perform the following steps to restore the backed up user data from the current version:
    1. Stop Kubernetes by running the microk8s.stop command.
    2. Restore the backed-up user data by running the following commands:
      cd ibm-rtas-case/inventory/ibmRtasBase/files
      sudo ./ restore [options] <backup-name>
      Note: You must replace <backup-name> with the name of the back up file that you saved.
      For more information about using additional parameter and overwriting the existing Persistent Volumes, see Backing up and restoring the user data on Ubuntu topic.
    3. Restart Kubernetes by running the microk8s.start command to start Rational® Test Automation Server.
  11. Optional: Run the following command to verify and test the installed server software:
    $ helm test {my-rtas} -n {namespace}
    • {my-rtas} with the release name that you provided for the server.
    • {namespace} is a name of the namespace that you created during the server install.


On successful installation of Rational® Test Automation Server, the output displays the URL to access the Rational® Test Automation Server UI.
