HCP Terraform Operator for Kubernetes

Note From this point forward, the terms HCP Terraform can be used interchangeably with Terraform Enterprise in all documents, provided that the contrary is indicated.

The Operator can manage the following types of resources:

• AgentPool manages HCP Terraform Agent Pools, HCP Terraform Agent Tokens and can perform TFC agent scaling
• Module implements API-driven Run Workflows
• Project manages HCP Terraform Projects
• Workspace manages HCP Terraform Workspaces

Troubleshooting

If you encounter any issues with the Operator there are a number of ways how to troubleshoot it:

• check the Operator logs:

  $ kubectl logs -f <POD_NAME>

  Logs for a specific CR can be identified with the following pattern:

  {"<KIND>": "<NAMESPACE>/<METADATA.NAME>", "msg": "..."}

  For example:

  2023-01-05T12:11:31Z INFO Agent Pool Controller {"agentpool": "default/this", "msg": "successfully reconcilied agent pool"}

• check the CR:

  $ kubectl get agentpool <NAME>
  $ kubectl get module <NAME>
  $ kubectl get project <NAME>
  $ kubectl get workspace <NAME>

• check the CR events:

  $ kubectl describe agentpool <NAME>
  $ kubectl describe module <NAME>
  $ kubectl describe project <NAME>
  $ kubectl describe workspace <NAME>
