How to install K3s without ServiceLB

I'm trying to install k3s by using k3sup. I want also to use kube-vip instead of ServiceLB.

For this reason, I first tried to install k3s on the control node with the following command:

k3sup install --k3s-channel stable --ip $CTRL_IP --user myuser --cluster --k3s-extra-args "--no-deploy traefik --no-deploy servicelb"

but it fails:

[INFO]  systemd: Starting k3s
Job for k3s.service failed because the control process exited with error code.
See "systemctl status k3s.service" and "journalctl -xeu k3s.service" for details.
Error: error received processing command: Process exited with status 1

Systemctl does not give any other useful information.

If I keep ServiceLB, K3s is correctly installed:

k3sup install --k3s-channel stable --ip $CTRL_IP --user myuser --cluster

All the guides I found do not mention any problem on that. How can I install k3s without servicelb?

Note: I tried also to use --no-extras instead of --k3s-extra-args "--no-deploy traefik --no-deploy servicelb", but it did not work.

Solution

  • Ok I solved by keeping traefik installation. The extra args were changed as follows:

    --k3s-extra-args "--no-deploy servicelb"
