Installing the server software on Azure Kubernetes Service

You can install HCL OneTest Server on Azure Kubernetes Service (AKS) that has a Kubernetes environment to run functional, integration, and performance tests. HCL OneTest Server combines all the capabilities into a single web-based browser for testers and non-testers. The capabilities include test runs, test data, test environment, or test reports.

Before you begin

  • You must have read and been familiar with additional Helm parameters. See Additional Helm parameters.

  • You must have performed the following tasks:

    • Completed the tasks provided in the Prerequisites section. See Prerequisites for installing the server software on Azure Kubernetes Service.

    • Optional: Enabled the autoscaler feature if you want a new container to be used only to run test assets and to open the test editor. See Cluster autoscaler on Azure Kubernetes Service.

    • Logged in to the AKS cluster.

      Note: You can run the az login command to log in to AKS interactively.
    • Subscribed to active Azure subscription.

      Note: You can run the az account set --subscription {subscription_name} command to set your active subscription.
    • Configured the location of your AKS cluster.

      Note: You can run the az configure --defaults location={location_name} command to set the location of your AKS cluster.
      Tip: You can run the following command to get the list of all the available locations:
      az account list-locations --query "[].{DisplayName:displayName, Name:name}" -o table

About this task

The following table lists the variables that you must replace with the actual value in the command.

Variables Description
{resource_group}

The name of the resource group that you created during the creation of the AKS cluster.

{azure_cluster}

The name of the Azure cluster that you created during the creation of the AKS cluster.

{azure_container_registry}

The name of the ACR that you created during the AKS setup.

{my-ingress-dns-name}

The Ingress name and DNS zone value that you provided during the setting up of the AKS cluster.

For example, if the Ingress name and DNS zone value that you provided are onetest, myorg.nonprod, then {my-ingress-dns-name} value must be onetest.myorg.nonprod.

{my-ots}
The release name of your choice.
Note: The release name must consist of alphanumeric characters that are in lowercase or - (hyphen). The release name must also start with an alphabetic character and end with an alphanumeric character. For example, my-org or abc-123.
{cloud-license-server-id}

The ID of the License Server for the initial team space, if you want to set the license for the first time.

Important: When you want to upgrade the product from the previous version, you must configure the value of License Server ID from the Team Space License Configuration page when the installation of the server is complete.
{password-seed}

A value of your choice for the password.

Important: This password seed is used to create several default passwords for the server. You must store the password seed securely. When you install the server software by using the backup of the user data, you can reuse the password seed. You can use this seed to restore the backed-up files either on the current or later versions of the server software.
{ip_address}.nip.io

The IP address that is assigned to Emissary-ingress.

You can run the following command to obtain the IP address of Emissary-ingress:
kubectl get ingress -A
Remember: The test-system is the name of the namespace. If you created a namespace by using a different value, then you must use that value in place of test-system in all the instances in this procedure.
HCL OneTest Server provides you with the test authoring capability, which utilizes a containerized version of the HCL OneTest Studio desktop authoring tools.
Note: By design, the test authoring feature provides you with the capability to author tests that include writing code, executing code, and accessing the shell. The container in Kubernetes that is used by the test authoring or editing feature does not run as root and the container is not privileged. Hence, it results in providing some protection to the host and other workloads that run on the same node.
You must not install the test authoring feature in the following scenarios:
  • If you administer a network policy for your server installation.

  • If you do not intend to use the test authoring feature.

Procedure

  1. Add the software registry to Helm by running the following command:
    helm repo add hclsoftware https://hclcr.io/chartrepo/ot
  2. Run the following command to get the latest updates from the repository:
    helm repo update
  3. Run the following commands to fetch the scripts that are used to install HCL OneTest Server:
    helm pull --untar hclsoftware/hcl-onetest-server --version 10.1051.0
    chmod +x hcl-onetest-server/files/*.sh
  4. Run the following command to configure kubectl to connect to the AKS cluster:
    az aks get-credentials -g {resource_group} -n {azure_cluster}
    Note: You can verify the connection to the AKS cluster by running the kubectl get nodes command that displays a list of the cluster nodes.
  5. Run the following script from the hcl-onetest-server/files directory to pull the images of HCL OneTest Server from the Harbor repository to ACR:
    bash hcl-onetest-server/files/move-images.sh {azure_container_registry}.azurecr.io/hcl-onetest hclcr.io/ot/hcl-onetest
    Tip: You can verify that multiple manifests are associated with the image in the ACR by running the following commands:
    az acr repository list -n {azure_container_registry} -otsv
    az acr repository show-manifests -n {azure_container_registry} --repository \
    $(az acr repository list -n {azure_container_registry} -otsv --query [0])
  6. Create a namespace in which you want to install the server software by running the following command:
    kubectl create namespace test-system
  7. Perform one of the following steps to enable Certificate Authority (CA) as trusted certificates and to create an ingress Secret:
    1. Run the following script from the hcl-onetest-server/files directory if your endpoints can resolve Azure private DNS zones:
      hcl-onetest-server/files/certificate.sh -n test-system -s ingress {my-ingress-dns-name}
    2. Run the following script from the hcl-onetest-server/files directory if your endpoints cannot resolve Azure private DNS zones:
      hcl-onetest-server/files/certificate.sh -n test-system -s ingress {ip_address}.nip.io
  8. Run the following command to install the server software:

    The following command installs the server software by referencing the images from ACR. Thereby, HCL OneTest Server can provide better performance.

    Notes:
    • If you enabled the autoscaler feature to use a new container only to run test assets and to open the test editor, then you must add -f hcl-onetest-server/values-dedicated-nodes.yaml in the following helm install command.

    • To provide enhanced security to HCL OneTest Server, the Sign up link on the Login page of HCL OneTest Server is not visible when you install the server software.

      If you want to enable the Sign up link on the Login page, then you must add the --set keycloak.signup.enabled=true parameter in the following helm install command.

    helm install {my-ots} ./hcl-onetest-server -n test-system \
    -f hcl-onetest-server/values-k8s.yaml \
    --set global.persistence.rwxStorageClass=azurefile \
    --set global.hclOneTestIngressDomain={my-ingress-dns-name} \
    --set global.hclFlexnetURL=https://hclsoftware.compliance.flexnetoperations.com \
    --set global.hclFlexnetID={cloud-license-server-id} \
    --set global.hclOneTestRegistry=<azure_container_registry>.azurecr.io/hcl-onetest \
    --set global.hclOneTestPasswordAutoGenSeed={password-seed}
    
  9. Run the following script from the hcl-onetest-server/files directory to verify and test the installed server software:
    hcl-onetest-server/files/helm-test-diag.sh {my-ots} -n test-system

Results

You have installed the server software. The terminal displays the following information:
  • The URL to access Keycloak to manage and authenticate users.

    The username can be keycloak and the password can be retrieved by running the following command:
    kubectl get secret -n test-system {my-ots}-keycloak-postgresql -o jsonpath="{.data.password}" | base64 --decode; echo 
    Where:
    • {my-ots} is the name of the release that was provided during the installation of the server software.

    • test-system is the name of the namespace that you created during the installation of the server software.

  • The URL to access the HCL OneTest Server UI.
