Install Release on Kubernetes On-premise Platform

This section describes the procedure of fresh installation of the Release application on Kubernetes on-premise platform using operator-based installer.

Intended Audience

This guide is intended for administrators with cluster administrator credentials who are responsible for application deployment.

Before You Begin

The following are the prerequisites required to migrate to the operator-based deployment:

  • Docker version 17.03 or later
  • The kubectl command-line tool
  • Access to a Kubernetes cluster version 1.17 or later
  • Kubernetes cluster configuration

Step 1—Create a folder for installation tasks

Create a folder on your workstation from where you will execute the installation tasks, for example, ReleaseInstallation.

Step 2—Download the Operator ZIP

  1. Download the release-operator-onprem.zip file from the Deploy/Release Software Distribution site.
  2. Extract the ZIP file to the ReleaseInstallation folder.

Step 3—Update the Kubernetes on-premise cluster information

To deploy the Release application on the Kubernetes cluster, update the Infrastructure file parameters (infrastructure.yaml) in the location where you extracted the ZIP file with the parameters corresponding to the Kubernetes On-premise Cluster Configuration (kubeconfig) file as described in the table. You can find the Kubernetes cluster information in the default location ~/.kube/config. Ensure the location of the kubeconfig configuration file is your home directory.

Note: The deployment will not proceed further if the infrastructure.yaml is updated with wrong details.

Infrastructure File Parameters Kubernetes On-premise Cluster Configuration File Parameters Parameter Value
apiServerURL server Enter the server parameter value.
caCert certificate-authority-data Enter the server details of the cluster.
tlsCert client-certificate-data Before updating the parameter value, decode to base64 format.
tlsPrivateKey client-key-data Before updating the parameter value, decode to base64 format.

Step 4—Update the default Digitial.ai Release Custom Resource Definitions.

  1. Update dairelease_cr file in the \digitalai-release\kubernetes path of the extracted zip file.
  2. Update the mandatory parameters as described in the following table:

    Note: For deployments on test environments, you can use most of the parameters with their default values in the dairelease_cr file.

Parameter Description
K8sSetup.Platform Platform on which to install the chart. For the Kubernetes on-premise cluster, you must set the value to PlainK8s
ingress.hosts DNS name for accessing UI of Digital.ai Release.
xlrLicense Convert the Digital.ai Release Repository Keystore file to the base64 format.
RepositoryKeystore Convert the Digital.ai Release Repository Keystore file to the base64 format.
KeystorePassphrase The passphrase for the RepositoryKeystore.
postgresql.persistence.storageClass Storage Class to be defined for PostgreSQL
rabbitmq.persistence.storageClass Storage Class to be defined for RabbitMQ
Persistence.StorageClass The storage class that must be defined as Kubernetes On-premise cluster

Note: For deployments on production environments, you must configure all the parameters required for your Kubernetes On-premise production setup, in the dairelease_cr.yaml file. The table in Step 4.4 lists these parameters and their default values, which can be overridden as per your setup requirements and workload. You must override the default parameters, and specify the parameter values with those from the custom resource file.

  1. Update the Values file with the license and keystore details

    1. Convert the Release license and the repository keystore files to the base 64 format.
    2. Run the following commands:

      • To convert the xlrLicense into base 64 format, run:

        cat <License.lic> | base64 -w 0
      • To convert RepositoryKeystore to base64 format, run:

        cat <keystore.jks> | base64 -w 0

        Note: The above commands are for Linux-based systems. For Windows, there is no built-in command to directly perform Base64 encoding and decoding. But you can use the built-in command certutil -encode/-decode to indirectly perform Base64 encoding and decoding.

  2. Update the default parameters as described in the following table:

    Note: The following table describes the default parameters in the Digital.ai dairelease_cr.yaml file. If you want to use your own database and messaging queue, refer Using Existing DB and Using Existing MQ topics, and update the dairelease_cr.yaml file. For information on how to configure SSL/TLS with Digital.ai Deploy, see Configuring SSL/TLS.

Step 5—Download and set up the XL CLI

Download the XL-CLI binaries.

```
wget https://dist.xebialabs.com/public/xl-cli/$VERSION/linux-amd64/xl
```
**Note**: For `$VERSION`, substitute with the version that matches your product version in the [public folder](https://dist.xebialabs.com/public/xl-cli/).
  1. Enable execute permissions.

    chmod +x xl
  2. Copy the XL binary in a directory that is on your PATH.

    echo $PATH

    Example

    cp xl /usr/local/bin
  3. Verify the Release version.

    xl version

Step 6—Set up the XL Deploy container instance

  1. Run the following command to download and start the local Digital.ai Deploy instance:

    docker run -d -e "ADMIN_PASSWORD=admin" -e "ACCEPT_EULA=Y" -p 4516:4516 --name xld xebialabs/xl-deploy:10.2
  2. To access the Deploy interface, go to:
    http://<host IP address>:4516/

Step 7—Activate the deployment process

Go to the root of the extracted file and run the following command:

xl apply -v -f digital-ai.yaml

Step 8—Verify the deployment status

  1. Check the deployment job completion using XL CLI.
    The deployment job starts the execution of various tasks as defined in the digital-ai.yaml file in a sequential manner. If you encounter an execution error while running the scripts, the system displays error messages. The average time to complete the job is around 10 minutes.

Note: The running time depends on the environment.

Deployment Status

To troubleshoot runtime errors, see Troubleshooting Operator Based Installer.

Step 9—Verify if the deployment was successful

To verify the deployment succeeded, do one of the following:

  • Open the Deploy application, go to the Explorer tab, and from Library, click Monitoring > Deployment tasks

    Successful Release Deployment

  • Run the following commands in a terminal or command prompt:

    Deployment Status Using CLI Command

Step 10—Perform sanity checks

Open the Deploy application and perform the required deployment sanity checks.
