How to setup minikube for testing?

Build Environment

Hi,

I’m trying to provide a minikube instance to use it during tests execution.

Unfortunately all my attempts failed so far.

(more links available but restricted to 2 max as i’m a new user)

they are all failing with various errors.
Anyone able to launch minikube? Or any other ways to have a Kubernetes instance available for testing on CircleCI?

regards,

I think using the K8s orb will probably be the easiest option: https://circleci.com/developer/orbs/orb/circleci/kubernetes

If that doesn’t work, I can definitely dig deeper into resources!

Hi,

thnaks for the suggestion. i wasn’t able to use the kubernetes orb neither.

I finally managed to have minikube working. Trying to share the main points:

  • requires to use a machine and not a docker image
  • use minikube vm-driver=docker
  • install conntrack (and iptables?)
  • install kubectl

I will share my branch when I will have finish to clean my config file and it will be merged in my master

Hi Apupier minikube does require the machine executor in which you can use image ubuntu-2004:202010-01 then you can install + configure the system.

I would also suggest experimenting with microK8s which runs much smoother since it’s provided by Canonical.

Thanks for the suggestion. In my case, our end-users are using more minikube, so preferred to stick with it.
After several attempts, I managed to slim down the configuration to have only few lines:

in a nutshell: use an image with .deb and docker vm-driver. it gives something like:

machine:
  image: ubuntu-2004:202010-01
steps:
  - run:
      command: |
        curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube_latest_amd64.deb
        sudo dpkg -i minikube_latest_amd64.deb
        minikube start --vm-driver=docker --kubernetes-version=v1.19.0
