K3s remove traefik

To install the K3s, on the new VM instance, you can simply run the script in the terminal:

curl -sfL https://get.k3s.io | sh -

After the installation and initial setup process (which can take a few minutes), you can access the k3s cluster using the kube config file located at the /etc/rancher/k3s/k3s.yaml.

Configuring installation

curl -sfL https://get.k3s.io | INSTALL_K3S_EXEC="server" sh -s - --flannel-backend none --token 12345

Configuration can be passed to the installer via environment variables.

Other way to do this is using /etc/rancher/k3s/config.yaml file.

See more at the k3s docs.

Installing k3s without Traefik

curl -sfL https://get.k3s.io | INSTALL_K3S_EXEC="server" sh -s - --disable-traefik

This will install k3s without Traefik

Removing Traefik from the already running k3s

sudo rm -rf /var/lib/rancher/k3s/server/manifests/traefik.yaml
helm uninstall traefik traefik-crd -n kube-system
sudo systemctl restart k3s

Traefik will be uninstalled and will not be reinstalled via HelmChartConfig when k3s is restarted.
