Helm Operator for DirectPV
To document how to get Helm Operator working to install DirectPV in any given cluster.
- Start by having a fresh new cluster of k8s or OpenShift:
- Create a new project:
rm -rf ~/directpv-operator
mkdir ~/directpv-operator
cd ~/directpv-operator- Get chart from folder: https://github.com/cniackz/directpv-helm-operator/tree/main/directpv-chart
operator-sdk init --plugins helm --domain quay.io --helm-chart /Users/cniackz/minio/directpv-workdir/directpv-chart- Edit below values in generated
Makefile
- Version should point to our latest version:
VERSION ?= 4.0.6
- Image base to some registry that you have access to:
IMAGE_TAG_BASE ?= quay.io/cniackz4/directpv-operator
- And use that for the image:
IMG ?= $(IMAGE_TAG_BASE):$(VERSION)
- Finally if you are on Mac M1 or M2 Chip, use buildx accordingly:
.PHONY: docker-build
docker-build: ## Build docker image with the manager.
docker buildx build --platform linux/amd64 -t ${IMG} .- Then, change the RBAC permissions to allow Operator control the different resources:
- Then, Build docker image:
make docker-build docker-push
- Install OLM
operator-sdk olm install
- Build operator bundle docker image
make bundle bundle-build bundle-push
Expected:
$ make bundle bundle-build bundle-push
operator-sdk generate kustomize manifests -q
