Docker required to run Makefile on kepler-operator

[arthurus-rex]

Following the steps in the docs, running make cluster-up on a system that has podman installed instead of docker, we receive the following error:

~/go/src/github.com/kepler-operator/tmp/local-dev-cluster/lib/utils.sh: line 182: docker: command not found
 ❯ docker run -d --restart=always --name kind-registry -p 127.0.0.1:5001:5000 --network kind registry:2

~/go/src/github.com/kepler-operator/tmp/local-dev-cluster/lib/utils.sh: line 51: docker: command not found
make: *** [Makefile:126: cluster-up] Error 127

Installing docker alleviates the issue. Could consider either adding podman compatibility to Makefile, or specifying in docs that docker is required.

@arthurus-rex You are correct. The docs should be updated to include docker as one of the requirements. Nice find.
Do you want to update this here: https://github.com/sustainable-computing-io/kepler-doc ?

[arthurus-rex]

Yes of course, I will gladly update this, thank you for your prompt response!
