With the operator-sdk guide v1.0, it is necessary to install operator-sdk in production environment when deploy an operator.
Is it possibile to deploy an operator without installing operator-sdk? Because it leads to more dependency and complexity.
How can I just generate CRD yaml, CR yaml and Contoller Image? Or any other more convenient way to publish an Operator？
You can change the make deploy command to generate deploy.yaml with all rbac and deployment objects needed for the operator. I struggle with my self until I found this solution.
Just change the deploy task in the make file.
$(KUSTOMIZE) build config/default | kubectl apply -f -
To
$(KUSTOMIZE) build config/default > deploy.yaml
Then run make deploy. And then copy the deploy.yaml and install it in your k8s or create a helm chart from it. This worked for me no need for operator-sdk in your environment.
Edit:
I didn't use CRD i use it to watch existing resources.
But it's look like the same solution should work with the install task for CRD and CR.
The operator-sdk is not intended to directly run operators in production. Instead, you should run your operator as a Deployment inside the cluster. https://v1-0-x.sdk.operatorframework.io/docs/building-operators/golang/tutorial/#2-run-as-a-deployment-inside-the-cluster
