    description of my changes

Test new docker image in paas-bootstrap and paas-cf

create branches for each of these repos and update the tags for the relevant docker images

eg: GDS11779:paas-bootstrap$ git diff diff --git a/concourse/tasks/delete-ssh-keys.yml b/concourse/tasks/delete-ssh-keys.yml index ad05cbb..4b4480e 100644 --- a/concourse/tasks/delete-ssh-keys.yml +++ b/concourse/tasks/delete-ssh-keys.yml @@ -4,7 +4,7 @@ image_resource: type: registry-image source: repository: - tag: 10f7bb56a8f4c0493acdd303ca08571ef3ecc8e9 + tag: 0a8c473a98866f99789a382ff8edbb324f6e35f0 inputs: - name: paas-bootstrap run:

Replace each instance of the old tag (10f7bb56a8f4c0493acdd303ca08571ef3ecc8e9) for the new tag (0a8c473a98866f99789a382ff8edbb324f6e35f0)

Push the changes to the branches and configure the pipelines to use these branches in your dev environment

eg: gds-cli aws paas-dev-admin -- make dev04 deployer-concourse pipelines DEPLOY_ENV=dev04 BRANCH=test_docker_branch

Run the pipelines to test the changes

Merge the docker-cloudfoundry-tools changes
