Set db-operator version on database CR during full reconcile

[bobertrublik]

• Issue: Add an information about the version of db operator that was running the last reconciliation  #79

The change is rather simple. I retrieve the pod db-operator runs in and extract the version from the image tag. I had to add a new POD_NAMESPACE environment variable to the db-operator deployment manifest so I can fetch the pod from the cluster.

I'm not sure if I should add more error handling when I split the image tag. What do you think?

I was thinking about something like that https://www.digitalocean.com/community/tutorials/using-ldflags-to-set-version-information-for-go-applications

It doesn't seem right to me that dbo will have to recieve data about itself from the k8s api. Fithermore, it doesn't have to be running in k8s

[bobertrublik]

Ah I didn't know that possibility existed. Not an issue, I will implement this. 🙂

Do you mean it could also run on Openshift or what did you have in mind?

In general, it should be possible to run it as a bin pointing to k8s from outside

[bobertrublik]

Does this go in the right direction?

[allanger]

Yep, it looks better to me, but I would put it to the status, not the spec

[bobertrublik]

Fixed here and in the chart repository. If you want, you can test the image using this build target in the Makefile,.

build: ## Build a container
	$(CONTAINER_TOOL) build ${CONTAINER_TOOL_ARGS} -t ${IMAGE_TAG} . ${CONTAINER_TOOL_NAMESPACE_ARG} --build-arg="VERSION=v1.23.0"

[allanger]

I would replace version to operatorVersion
Also I'm not sure if the common helper is a good place for storing the var, but I can't find a better one, so I'm alright with that

[bobertrublik]

I renamed the variable but had issues running make generate because I'm on Go 1.22.1 which is incompatible with controller-gen 0.13.0. kubernetes-sigs/controller-tools#888

Are you fine with me updating the codebase and Github workflows to 1.22.1? After the controller-gen update the generated CRDs have a little different syntax for descriptions.

[allanger]

Yep, why not. Let's upgrade

[bobertrublik]

I applied the necessary changes for the 1.22.1 update, renamed the variable to operatorVersion and copied the generated CRDs to the db-operator charts PR.

Thanks, it looks good to me now
