Implement a stable way to handle the terraform state

[sebastian-sommerfeld-io]

Store terraform state in a separate private repository

• [x] Create repo configs-persistent-data (private) with directory structure matching configs repo but without any docs
• [x] Add docs to configs repo (github setup)
• [x] Update src/main/github/assets/help.adoc with new options -> cleanup
• Implement (add prepare and cleanup/finally steps to script and pipeline)
  • INIT
    • [x] mkdir -p /tmp/repos
    • [x] Clone repo (/tmp/repos/configs-persistent-data)
    • [x] Copy tfstate to correct location
  • APPLY
    • same as today
  • PERSIST-DATA (in generate-docs stage)
    • [x] Copy tfstate back to /tmp/repos/configs-persistent-data
    • [x] Commit and push to configs-persistent-data (only state file)
  • CLEANUP
    • [x] rm -rf /tmp/repos ... run always (same as google chat)
    • [x] clean local filesystem ??
• [x] Works from pipeline?
