Thanks for the tip. I am much closer but I'm getting some undesirable
characters added to the var named "key" I'm setting.
1. - hosts: swarm-init
2. tasks:
3. - shell: docker swarm init
4. - shell: docker swarm join-token -q manager
5. register: manager
6. - set_fact:
7. manager: "{{ manager.stdout_lines }}"
8. - shell: docker swarm join-token -q worker
9. register: worker
10. - set_fact:
11. worker: "{{ worker.stdout_lines }}"
12. - hosts: swarm-worker
13. vars:
14. key: "{{ hostvars[groups['swarm-init'][0]]['worker'] }}"
15. tasks:
16. - shell: "docker swarm join --token {{ key }} {{ swarmmanager }}:2377"
Inventory
1. [swarm-init]
2. myhost1
3.
4. [swarm-manager]
5. myhost1
6.
7. [swarm-worker]
8. myhost2
9.
10. [swarm-manager:vars]
11. swarmmanager=myhost1
12.
13. [swarm-worker:vars]
14. swarmmanager=myhost1
The output:
