Docker Playbook yml - ssh to a host with different port

Question

I have deploy script for a Docker container.

- hosts: "{{ HOSTS|default('...') }}"
  remote_user: "{{ USER|default('root') }}"
  vars:
    deploy_port: "{{ DEPLOY_PORT|default(80) }}"
    git_branch: "{{ GIT_BRANCH|default('development') }}"
    python_settings: "{{ PYTHON_SETTINGS|default('development') }}"
  tasks:
  - name: Log into Docker registry
    docker_login:
      registry_url: ...
      username: ...
      password: ...
  ....

So firstly I do SSH to a HOSTS with user USER. But now, I have HOSTS that have different ssh port (not 22). How do I set this?

I try with port, and it did't work

- hosts: "{{ HOSTS|default('...') }}"
  port: 23
  remote_user: "{{ USER|default('root') }}"
  vars:
    deploy_port: "{{ DEPLOY_PORT|default(80) }}"
    git_branch: "{{ GIT_BRANCH|default('development') }}"
    python_settings: "{{ PYTHON_SETTINGS|default('development') }}"
  tasks:
  - name: Log into Docker registry
    docker_login:
      registry_url: ...
      username: ...
      password: ...
  ....

This is a var you should set in your inventory for hosts that do not have the default port. Its name is ansible_port (and not port as you tried).

Very basically:

• Create a host_vars folder (at same level as your playbook or at same level as your inventory file)
• For each machine having a different port that 22, create a <name_of_host>.yml file in host_vars with the following content (replace XX with your actual port):

   --- ansible_port: XX
