Deploy OpenShift for e2e testing

Standard setup for an e2e test environment on supported clusters is provided in this directory. Subdirectories contain the default profiles. The deployment uses the openshift/origin-ansible:latest image to launch clusters.

Prerequisites:

  • Docker 1.12+ installed and available on your local machine
  • Your system time must be up to date in order for gcloud to authenticate to GCE (run sudo ntpd -gq in your VM if necessary)

Profiles

  • gcp-dev (default) - 1 master, 3 node cluster with bootstrapping (uses the openshift-gce-devel project, suitable for developers)
  • gcp - 1 master, 3 node cluster with bootstrapping (uses the openshift-gce-devel-ci project, suitable for CI)
  • gcp-ha - 3 master, 3 node cluster with bootstrapping (uses the openshift-gce-devel-ci project, suitable for CI)

In each profile, see vars-origin.yaml for the default settings (which is common across all profiles) and vars.yaml for the variables that differ.

Configure a profile

This is the typical workflow to configure the development profile gcp-dev (but would apply to any other profile).

Clone the shared secrets repo to $SHARED_SECRETS:

git clone [email protected]:openshift/shared-secrets.git $SHARED_SECRETS

Copy secrets to their well-known locations in the profile directory:

cp $SHARED_SECRETS/gce/aos-serviceaccount.json $RELEASE_TOOLS/gcp-dev/gce.json

cp $SHARED_SECRETS/gce/[email protected] $RELEASE_TOOLS/gcp-dev/ssh-privatekey

cp $SHARED_SECRETS/mirror/ops-mirror.pem $RELEASE_TOOLS/gcp-dev/ops-mirror.pem

Configure installer variables

Add new installer variables to a file such as gcp-dev/zz_vars.yaml (any YAML file in the profile directory will be treated as a variables file, and for now, the zz_ prefix ensures that your variables will override any predefined ones). Keep in mind that the precedence order of the variable files in the profile is unspecified: to override variables in vars.yaml or vars-origin.yaml just modify those files directly for now.

Usage

You can set an alternate profile by passing PROFILE=gcp on the make arguments.

# launch cluster using the latest RPMs
$ make WHAT=mycluster up

# after cluster is launched, admin.kubeconfig is copied locally
$ KUBECONFIG=gcp-dev/admin.kubeconfig oc status

# teardown cluster
$ make WHAT=mycluster down

# get a shell in the ansible environment
$ make WHAT=mycluster sh

# launch a different profile
$ make WHAT=mycluster PROFILE=gcp-ha

Advanced configuration

The following ansible variables are commonly used:

  • openshift_test_repo is the URL to a yum repo to use to install
  • openshift_image_tag (optional) is the suffix of the image to run with
  • openshift_pkg_version (optional) is the exact package value to use -0.0.1 if installing RPMs that don't match the desired version

The following environment variables can be provided:

  • OPENSHIFT_ANSIBLE_IMAGE (defaults to openshift/origin-ansible:latest) the image to deploy from

The following files can be added to a profile:

  • gce.json containing the GCP service account credentials to use that have permission to create instances, networks, and a bucket in the project used by the profile
  • ops-mirror.pem containing the client certificate for the OpenShift ops mirror
  • ssh-privatekey (optional) with the private key to use for the GCP instances
  • ssh-privatekey.pub (optional) a key to use with the above private key

Pushing images to the cluster registry

  1. Add the cluster's registry (e.g. docker-registry-default.apps.$WHAT.origin-gce.dev.openshift.com) to the local Docker daemon's insecure registry list.

  2. Log in to the cluster's registry using an SA from the namespace which should receive the image:

    oc sa get-token -n openshift builder | docker login -u builder --password-stdin docker-registry-default.apps.$WHAT.origin-gce.dev.openshift.com

  3. Tag an image pointing at the cluster registry in the desired namespace:

    docker tag github.com/openshift/origin:b42d282 docker-registry-default.apps.$WHAT.origin-gce.dev.openshift.com/openshift/origin:b42d282

  4. Push an image to the cluster registry:

    docker push docker-registry-default.apps.$WHAT.origin-gce.dev.openshift.com/openshift/origin:b42d282
