14.3. Manually gathering logs with SSH access to your host(s)

Manually gather logs in situations where must-gather or automated collection methods do not work.

Prerequisites

  • You must have SSH access to your host(s).

Procedure

  1. Collect the bootkube.service service logs from the bootstrap host using the journalctl command by running:

    $ journalctl -b -f -u bootkube.service
  2. Collect the bootstrap host’s container logs using the podman logs. This is shown as a loop to get all of the container logs from the host:

    $ for pod in $(sudo podman ps -a -q); do sudo podman logs $pod; done
  3. Alternatively, collect the host’s container logs using the tail command by running:

    # tail -f /var/lib/containers/storage/overlay-containers/*/userdata/ctr.log
  4. Collect the kubelet.service and crio.service service logs from the master and worker hosts using the journalctl command by running:

    $ journalctl -b -f -u kubelet.service -u crio.service
  5. Collect the master and worker host container logs using the tail command by running:

    $ sudo tail -f /var/log/containers/*
