PingCap CI/CD public configurations

New top level directories

• /jobs store Jenkins CI job DSL files.
• /pipelines store Jenkins CI pipeline scripts.
• /libraries store Jenkins CI shared libraries.

File structure for jobs and pipelines

• using <org>/<repo>/<branch-special>/<pipeline-name>.groovy structure.
• using dir soft link to reduce duplicate pipeline files for branch special, for an example:
  • soft link release-6/ to trunk/
  • soft link release-6.2/ to release-6/
  • create dir release-6.1/ because special steps.
  • when step in release 7.x, soft link release-7/ to trunk/
  • when new step should added in release 7.x
    1. detach the soft link release-6/ to trunk
    2. create copy trunk/ to release-6/
    3. update files in release-7/ or trunk(real path).

Job DSL important usage

• Do not use light checkout: avoid soft link in git.
