For tasks that wait or run for a long time without producing output, I found it necessary to add -o ServerAliveInterval=50 to ssh parameters to enable keepalives.

Reboot task might be "racy": ostreedev/ostree#1548

[athajaerel]

Can't be the reboot module --- it's the "wait for nodes" task which is a command.

- name: 'Wait for all nodes to exist'
  register: 'reg_nodes'
  retries: 120
  delay: 20
  until: 'reg_nodes is success'
  delegate_to: '{{ groups.k3s_primary_masters | first }}'
  command:
    argv:
      - '{{ k3s_binary_dir }}/kubectl'
      - 'get'
      - 'node'
      - '{{ fqdn }}'

Would be fixed by #175 , most likely.

Not forgetting to fork off a ticket for the outputs which don't fit...
