🐛 Check cluster is running for non-standalone Make targets

[bentito]

We have several non-standlone Make targets

• test-e2e
• kind-load
• install
• only-deploy-manifest

The above targets rely on Kind to be running.

Unfortunately, currently, errors returned from the Go code are pretty cryptic. Better would be an explicit catch and error when a Kind cluster is not found when these targets are run.

Currently we have:

catalogd checking_kind_running $ make test-e2e
/Users/btofel/go/bin/ginkgo-v2.20.2  -trace -vv  test/e2e
Running Suite: E2E Suite - /Users/btofel/workspace/catalogd/test/e2e
====================================================================
Random Seed: 1729265504

Ginkgo ran 1 suite in 4.681573708s

Test Suite Failed
make: *** [test-e2e] Error 1

wha?

but it would be better to have:

$ make test-e2e
if ! kubectl config current-context >/dev/null 2>&1; then \
		echo "Error: Could not get current Kubernetes context. Use 'run' or 'e2e' targets first."; \
		exit 1; \
	fi
Error: Could not get current Kubernetes context. Use 'run' or 'e2e' targets first.
make: *** [check-cluster] Error 1

This check might be a bit too presumptuous. For example, someone running test-e2e might want to run the tests after running kind create cluster --name=foobar and tilt up.

It may even be that someone wants to run the e2es against a non-kind cluster that already has OLM deployed.

[bentito]

Changed to make it more generic like this:

.PHONY: check-cluster
check-cluster:
	if ! kubectl config current-context >/dev/null 2>&1; then \
		echo "Error: Could not get current Kubernetes context. Use 'run' or 'e2e' targets first."; \
		exit 1; \
	fi

wdyt?
