Learning playground for k8s, helmfiles and k3d

Cluster k3d

Start the cluster without integrated Traefik 1.7

k3d cluster create mycluster -p "80:80@loadbalancer" --registry-use k3d-registry.k3d.lan.carmier.fr:5000 --k3s-server-arg "--no-deploy=traefik"

k3d kubeconfig merge mycluster --kubeconfig-switch-context

Install Traefik 2.x

helm repo add traefik https://containous.github.io/traefik-helm-chart
helm install traefik traefik/traefik

To access Traefik dashboard on http://localhost:9000

kubectl port-forward $(kubectl get pods --selector "app.kubernetes.io/name=traefik" --output=name) 9000:9000

Delete the cluster

k3d cluster delete newcluster

Application container

Build and push the image to k3d registry Note: Due to HTTPS/HTTP limitation we need to push to localhost but the k8s will refer with the name provided on k3d spawn.

docker build -t localhost:5000/loadtest .
docker push localhost:5000/loadtest

Helmfile

Start the application

helmfile --environment python-dev   apply

Delete the application

helmfile --environment python-dev   delete

Notes

Add registry credentials as secrets (if needed)

kubectl create secret docker-registry regcred --docker-server=myregistry --docker-username= --docker-password= --docker-email=
