Create and publish OLM bundle

• adds facility to create operational OLM bundle (scripts/olm-bundle.sh)

• add CI jobs for publishing Bundle and Catalog

  • for end-users to consume published Bundle and Catalog they need to follow #226 (comment 698219139)

Testing

See #226 (comment 699395470) for more

Prerequisites

• autodeploy.sh script can be downloaded separately from !220 (merged)

• have a read/write access to some container registry and make sure you're logged into it. For example: registry.gitlab.com/dmakovey/gitlab-operator-bundle

  • registry needs to be world-readable as k8s cluster (or more precisely OLM) will be pulling from it.

Process

Current process that works in KinD:

OLM_BUNDLE_SH="scripts/olm_bundle.sh"
AUTODEPLOY_SH="~/work/gitlab-operator.293-automate-gitlab-deployment-with-operator/scripts/autodeploy.sh"

export GITLAB_CHART_DIR=~/work/gitlab  # needed for some of the auxilary scripts setting up env
export KIND_CLUSTER_NAME="olm37" 
export GITLAB_CR_DEPLOPOY_MODE="ss"    # ss - self-signed, cm - Cert Manager
export LOCAL_IP=192.168.3.194          # your local cluster IP, for KinD it's local IP
export GITLAB_OPERATOR_DIR=. 
export GITLAB_CHART_VERSION="5.1.5"    # make sure that chart version is CHART_VERSIONS 

# Initialize infrastructure. Add CertManager
# this could also be achieved manually by creating k8s cluster following developer docs for cluster setup
# https://gitlab.com/gitlab-org/charts/gitlab/-/blob/master/doc/development/environment_setup.md
# autodeploy.sh is just a convenience wrapper:
${AUTODEPLOY_SH} create_cluster install_certmanager


export OSDK_BASE_DIR=".build/operatorsdk37"   # we're going to generate our bunlde here
export KIND_CLUSTER_NAME="olm37"              # match KIND_CLUSTER_NAME from above
export BUNDLE_IMAGE_TAG="beta37"              # image Tag that will be applied to built bundle/catalog
export OPERATOR_TAG="0.1.0"                   # Operator release to reference (image tag for container)

# create a container registry and log into it prior to testing, for example:
export BUNDLE_REGISTRY="registry.gitlab.com/dmakovey/gitlab-operator-bundle"
