Build

To build the operator, clone this repo into your GOPATH and run make. NOTE: Please ensure that the container image repo and tag are customized.

$ mkdir -p ${GOPATH}/src/github.com/embercsi
$ git clone -b devel https://github.com/embercsi/ember-csi-operator
$ cd ember-csi-operator
$ make build

If the used Docker release supports multistage builds, you can enable this by setting the MULTISTAGE_BUILD env var:

$ MULTISTAGE_BUILD=1 make build

Catalog build

  1. Create a new CSV file using the latest ember-csi container. Replace 0.9.x with the next version you want to use.
$ pushd build/olm-catalog/
$ CONSOLE_VERSION=4.6 ./olm-csv-gen.sh
$ popd
$ mkdir -p deploy/olm-catalog/0.9.x
$ cp deploy/olm-catalog/0.9.4/ember-csi-operator.crd.yaml deploy/olm-catalog/0.9.x/ember-csi-operator.crd.yaml
$ cp deploy/olm-catalog/next/ember-csi-operator.vX.Y.Z.clusterserviceversion.yaml deploy/olm-catalog/0.9.x/ember-csi-operator.v0.9.x.clusterserviceversion.yaml

  1. Update deploy/olm-catalog/ember-csi-operator.package.yaml to your next version.

  2. Build and push a new catalog container

$ podman build -f build/Dockerfile.catalog -t quay.io/embercsi/embercsi-catalog:latest deploy/olm-catalog
$ podman push quay.io/embercsi/embercsi-catalog:latest
  1. Deploy using ember-catalog operator
