  • helm (pinned)
  • terraform (pinned)
• Start Jenkins through custom entrypoint/support scripts while preserving standard container behavior.

• jenkins.sh: container startup and Jenkins process launch.
• jenkins-support: shared shell helper functions.
• install-plugins.sh: plugin install/dependency resolution helper.
• init.groovy: initial Jenkins controller setup hook.

docker run --rm -p 8080:8080 -p 50000:50000 docker-jenkins:local

Jenkins UI should be available at http://localhost:8080.

Versioning Notes
