Run KinD (Kubernetes in Docker) as part of Gitlab CI job

.gitlab-ci.yml

#Spin up Kubernetes control plane as part of before_script, and destroys it using after_script
#Some custom logic to get to the right ip address
#Requres the gitlab docker runner, with "pass-thru" to the host docker socket.

stages:
  - test
image: python:3.6.6 #the docker image you run in needs Docker installed, and access to the host docker socket.

Were you able to do a health check in a deployment you made? I'm trying to do a deployment of a nginx and then do a basic curl to check the status, but I'm not being able to do so. Can't get it right with the network logic behind the gitlab runner and the kind container. I'm using the image docker-git. Any idea?

Hi, glad it helped you! I'm afraid I haven't worked on this for many years so I don't have any helpful tips to share, sorry!

@pirolas001, I don't know if this would help, but when doing local testing, I was able to make my web service that's running in the cluster accessible like this: kubectl port-forward service/<service name> <local port>:<service's target port>. Perhaps kubectl proxy might also help?

I am having issues with using a local GH Runner and building the cluster locally, it seems that I can't reconnect to the cluster in a seperate stage, has anyone successfully done this with kind and podman on wsl2?
