k3s-dbruno

This is a snap of k3s, a fully conformant production-ready Kubernetes distribution.

Install

To install the snap from the store use:

snap install k3s-dbruno --edge --devmode

After installation a couple of small tweaks are required:

• Create the /run/user/0/snap.k3s dir

  sudo mkdir -p /run/user/0/snap.k3s sudo chmod 700 /run/user/0

• Download and parse the cri-containerd apparmor profile

  sudo wget https://raw.githubusercontent.com/dbruno74/k3s-dbruno/main/cri-containerd.apparmor.d -O /var/lib/snapd/apparmor/profiles/cri-containerd.apparmor.d sudo apparmor_parser -r /var/lib/snapd/apparmor/profiles/cri-containerd.apparmor.d

Alternatively, you can download the install-k3s-dbruno.sh script and run on your host:

sudo wget https://raw.githubusercontent.com/dbruno74/k3s-dbruno/main/install-k3s-dbruno.sh
chmod 755 install-k3s-dbruno.sh
./install-k3s-dbruno.sh

Note: if your host is Ubuntu Core, wget is not available, you can use wget-simosx snap instead

snap install wget-simosx

Run

*k3s server*

Just start the k3s-daemon service

snap start k3s-dbruno.k3s-daemon

k3s will be launched with the "server" parameter. In case you want to change the k3s service command line, use snap set

snap set k3s-dbruno k3s-cmd-line="server --node-name k3s-server"

To print k3s daemon logs:

snap logs k3s-dbruno.k3s-daemon -f

To stop the server:

snap stop k3s-dbruno.k3s-daemon

*k3s agent*

Set the k3s daemon command line first

snap set k3s-dbruno k3s-cmd-line="agent --server https://<k3s server address>:6443 --token <k3s server's token>"

To get the k3s server token, login to k3s server at , then:

sudo cat /var/snap/k3s/current/var/lib/rancher/k3s/server/token

Then start the k3s-daemon service

snap start k3s-dbruno.k3s-daemon

To print k3s daemon logs:

snap logs k3s-dbruno.k3s-daemon -f

To stop the server:

snap stop k3s-dbruno.k3s-daemon
