Hello,
Does anyone have by any chance an ansible playbook to setup docker on a debian trixie?
This is my first experience with Ansible, i thought this would be easy and straightforward. I used existing ones for debian 12 as template and yes, with ai, and taking things from other templates, i am trying to make this work. but for the life of me, i cannot crack this.
i began with the most simple steps:
- name: install Docker
hosts: all
become: true
tasks:
- name: Install apt-transport-https
ansible.builtin.apt:
name:
- apt-transport-https
- ca-certificates
- lsb-release
- gnupg
state: latest
update_cache: true
- name: Create keyrings directory
ansible.builtin.file:
path: /etc/apt/keyrings
state: directory
mode: '0755'
- name: Add Docker GPG key
ansible.builtin.shell: |
curl -fsSL https://download.docker.com/linux/debian/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg
chmod a+r /etc/apt/keyrings/docker.gpg
args:
creates: /etc/apt/keyrings/docker.gpg
- name: Add Docker repository
ansible.builtin.apt_repository:
repo: "deb [arch=amd64 signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/debian trixie stable"
state: present
filename: docker
- name: Install Docker
ansible.builtin.apt:
name:
- docker-ce
- docker-ce-cli
- containerd.io
- docker-buildx-plugin
- docker-compose-plugin
state: latest
update_cache: true
and added some debug stuff that really didnt help that much:
- name: Install Docker Engine and Docker Compose on Debian (Ansible WebUI compatible)
hosts: all
become: true
become_user: root
vars:
docker_packages:
- docker-ce
- docker-ce-cli
- containerd.io
- docker-buildx-plugin
- docker-compose-plugin
tasks:
- name: Ensure required packages are installed
apt:
name:
- ca-certificates
- curl
- gnupg
update_cache: yes
state: present
delegate_to: "{{ inventory_hostname }}"
- name: Ensure /etc/apt/keyrings exists
file:
path: /etc/apt/keyrings
state: directory
mode: '0755'
delegate_to: "{{ inventory_hostname }}"
- name: Get system architecture for Docker repo
ansible.builtin.command: dpkg --print-architecture
register: dpkg_architecture
changed_when: false
delegate_to: "{{ inventory_hostname }}"
- name: Download Docker GPG key
ansible.builtin.get_url:
url: https://download.docker.com/linux/debian/gpg
dest: /etc/apt/keyrings/docker.asc
mode: '0644'
delegate_to: "{{ inventory_hostname }}"
- name: DEBUG - Check if GPG key exists
ansible.builtin.stat:
path: /etc/apt/keyrings/docker.asc
register: gpg_key_stat
delegate_to: "{{ inventory_hostname }}"
- name: DEBUG - Show GPG key status
ansible.builtin.debug:
msg: "GPG key exists: {{ gpg_key_stat.stat.exists }}, Size: {{ gpg_key_stat.stat.size | default('N/A') }}"
- name: DEBUG - List keyrings directory
ansible.builtin.command: ls -lah /etc/apt/keyrings/
register: keyrings_list
delegate_to: "{{ inventory_hostname }}"
- name: DEBUG - Show keyrings directory contents
ansible.builtin.debug:
var: keyrings_list.stdout_lines
- name: Add Docker APT repository (correct for Debian 13)
ansible.builtin.apt_repository:
repo: "deb [arch={{ dpkg_architecture.stdout }} signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/debian {{ ansible_distribution_release }} stable"
filename: docker
state: present
delegate_to: "{{ inventory_hostname }}"
- name: DEBUG - Check if repo file exists
ansible.builtin.stat:
path: /etc/apt/sources.list.d/docker.list
register: repo_file_stat
delegate_to: "{{ inventory_hostname }}"
- name: DEBUG - Show repo file status
ansible.builtin.debug:
msg: "Repo file exists: {{ repo_file_stat.stat.exists }}"
- name: DEBUG - Show repo file contents if exists
ansible.builtin.command: cat /etc/apt/sources.list.d/docker.list
register: repo_contents
when: repo_file_stat.stat.exists
failed_when: false
delegate_to: "{{ inventory_hostname }}"
- name: DEBUG - Display repo contents
ansible.builtin.debug:
var: repo_contents.stdout_lines
when: repo_file_stat.stat.exists
- name: Update apt cache after adding repo
apt:
update_cache: yes
delegate_to: "{{ inventory_hostname }}"
- name: Install Docker packages
apt:
name: "{{ docker_packages }}"
state: present
delegate_to: "{{ inventory_hostname }}"
- name: Enable & start Docker
service:
name: docker
state: started
enabled: yes
delegate_to: "{{ inventory_hostname }}"
but everytime it fails at adding the package because its not found. because the repo was not added, my keyrings folder is miserably empty.
the target server has only root. so no user confusion there. yes, i know. bad practice. but its a learning exercise and its a lxc within my home network not internet exposed.

I am using https://ansible-webui.oxl.app/ although i doubt it has any effect whatsoever. but then again, i know next to nothing of ansible as of yet. so, for sure: what i am missing is incredibly dumb.
any help will be greatly appreciated.
