Playbook stuck while starting the RKE2 service on agents

[leon-andria]

Summary

In the troubleshooting section here: https://github.com/lablabs/ansible-role-rke2#troubleshooting, it mentions that it might be a network limitation.

The problem is that the RKE2 script is never executed on the agent which has condition with the variable installed_rke2_version. While that variable is depends on condition "rke2-server.service" in ansible_facts.services.

Below is the changes I made to fix the issue:

Before the Run AirGap RKE2 scripttask (https://github.com/lablabs/ansible-role-rke2/blob/dc6d4267dd346bb133baf662532bb797e0408270/tasks/rke2.yml#L91), I added the following tasks by checking that the rke2 binary path exists and don't relying on this line https://github.com/lablabs/ansible-role-rke2/blob/dc6d4267dd346bb133baf662532bb797e0408270/tasks/rke2.yml#L89.

- name: Check rke2 bin exists
  ansible.builtin.stat:
    path: "{{ rke2_bin_path }}"
  register: rke2_exists

- name: Check RKE2 version
  ansible.builtin.shell: |
    set -o pipefail
    {{ rke2_bin_path }} --version | grep -E "rke2 version" | awk '{print $3}'
  args:
    executable: /bin/bash
  changed_when: false
  register: installed_rke2_version
  when: rke2_exists.stat.exists

Steps to Reproduce

- name: Deploy RKE2
  hosts: all
  become: yes
  vars:
    rke2_version: v1.26.0+rke2r2    
    rke2_api_ip : 192.168.1.10

      - cilium
  roles:
     - role: lablabs.rke2

master-02 ansible_host=192.168.1.11 rke2_type=server

[workers]

worker-02 ansible_host=192.168.1.21 rke2_type=agent

[k8s_cluster:children]
masters
workers

Expected Results

Worker nodes should be provisioned if the rke2.sh script have been executed on the following task https://github.com/lablabs/ansible-role-rke2/blob/dc6d4267dd346bb133baf662532bb797e0408270/tasks/rke2.yml#L100

Actual Results

It's just hanging until timeout.

I tried your changes as described but they didn't work for me (airgapped, 3 workers, HA mode). I still had to run the RKE2 agent script by hand (on the workers). The install scripts runs correctly and the binaries exist but the execution of the agent service didnt (or its creation)
