Launch local cluster

k3d create -n myCluster

With a local registry

Using Tilt’s script, it launches a local registry to accelerate local development

curl https://raw.githubusercontent.com/tilt-dev/k3d-local-registry/master/k3d-with-registry.sh | bash /dev/stdin \
  -w 2 \
  -p "80:80" \
  -p "443:443" \
  --server-arg "--no-deploy=traefik"

-w: define the number of worker you want (k3s node).
-p: published port (like Docker) ! If you expose TCP/UDP port with traefik, you have to publish port to access it.
--no-deploy=traefik: option to do not deploy feature. It is useful to not deploy Traefik if you have your own ingress controller.

Storage

If you have issue with pvc, verify that storageClassName is not defined as default. Indeed, with k3s only local-path storage is allowed and default className prevent from using this.

La série « Jé pa l’temps » est une série de tutoriels rapides en mode “prise de note” pour avoir une trace de tout ce dont je ne peux me rappeler et pourquoi pas le partager à d’autre. On va à l’essentiel, laissons les jolis pavés à d’autres sites comme medium… LOL !
