Docker and AWS ECR

Pull a docker container from a public registry and upload it to your account registry

Parameters

DOCKER_IMAGE Expects a container image name in the format <Docker repo>:<docker tag>, which will be deconstructed and assigned to overwrite the default Docker environment variables DOCKER_REPO, DOCKER_TAG, REMOTE_DOCKER_REPO and REMOTE_DOCKER_TAG.

Alternatively these could be presented as individual Parameters.

Stages

Setup

Overwrite default Docker environment variables with those specified as Parameters.

Pull Image

Perform the hamlet "Manage Docker" action, pulling the selected container image from Dockerhub to the local registry.

Example

#!groovy

def dockerImages = [
    '<Docker repo>:<docker tag>'
]

    agent {
        label '<hamlet agent label>'
