Description

SAP Automation Pilot has the functionality to run scripts in an isolated Linux environment which provides a large array of useful tools and runtimes including kubectl, make and helm. It migth be useful to pull a git repo, containing a helm chart project, build it and deploy it to a kubernetes cluster.

This examples show how to configure your access to git and kubernetes cluster. Clone a repository containing helm project that builds with make. Build a make target and deploy a helm chart to kubernetes cluster.

The example helm chart deploys a simple busy box deployment with a single replica to the default namespace.

DISCLAIMER: the make tool is restricted to the current user and all security restrictions apply to any task that make tries to execute, so only make targets that do not require more privileges than the provided user can be leveraged in that way.

DISCLAIMER: the script execution time is limited, so any long running jobs will not be able to finish.

Please refer to the documentation for more details about the Execute Script functionality in Automation Pilot.

Requirements

Base64 encoded kubeconfig with access to a kubernetes cluster.

How to use

Import the content of examples catalog in your Automation Pilot tenant.

• Navigate to the Kubeconfig input and put your base64 encoded kubeconfig as the kubeconfig value.
• Navigate to the HelmExample command and trigger it to see it in action.

OPTIONAL:

• If you wish to use a different GIT repository than the provided one you can navigate to the GitAccess input and
  • put an access token with read permissions as the token value
  • put the address of the repository to use without the protocol
• You can then go to the HelmExample command and modify
  • helmProjectPath input key to point to the root directory of your helm project after cloning
  • makeTarget to use your desired make target

Cleaning up

To clean up the example resources on your kubernetes cluster you can trigger the HelmExample command with uninstall_app as the makeTarget input, or alternatively a cleanup target of your custom repository if you have configured one.
