Docker

The Docker library will build docker images and push them into a docker repository.

Steps Contributed

Table 1. Steps
Step	Description
`build()`	builds a container image, tagging it with the Git SHA, and pushes the image to the defined registry
`get_images_to_build()`	inspects the source code repository based upon the configured `build_strategy` to determine which container images to build
`login_to_registry()`	logs in to the configured container registry
`retag()`	retags the container images determined by `get_images_to_build()`

Example Configuration Snippet

libraries{
  docker {
     build_strategy = "dockerfile"
     registry = "docker-registry.default.svc:5000"
     cred = "openshift-docker-registry"
     repo_path_prefix = "proj-images"
     remove_local_image = true
  }
}

Configurations

Table 2. Docker Configuration Options
Field	Description	Default Value	Required
build_strategy	Sets how the library will build the container image(s); Must be dockerfile, docker-compose, or modules	dockerfile	false
registry	Where the container images produced during the pipeline builds are going to be pushed to		true
cred	Credentials used for the repository where different docker pipeline tools are stored.		true
repo_path_prefix	The part of the repository name between the registry name and the last forward-slash	""	false
remove_local_image	Determines if the pipeline should remove the local image after building or retagging	false	false

External Dependencies

A Docker registry must be set up and configured. Credentials to the repository are also needed.
Either the github or github_enterprise library needs to be loaded as a library inside your pipeline_config.groovy file.
