Ansible on Ubuntu 22.04 LTS: Docker CE Installation Complete Guide

Ubuntu 22.04 LTS (Linux 5.15) reached general availability on 2022-04-21 and is supported standard 2027-04, ESM 2032-04. Jammy Jellyfish, OpenSSL 3.0, GNOME 42. This guide shows how to automate docker ce installation on Ubuntu 22.04 LTS with Ansible end-to-end: prerequisites, an opinionated playbook using the ansible.builtin.apt module, validation, and troubleshooting.

Every example is tested with ansible-core 2.18 LTS on a Linux control node and is idempotent — re-running the playbook converges to the same state with zero changed tasks.

Why Docker CE Installation on Ubuntu 22.04 LTS

Ubuntu 22.04 LTS is a workhorse for production Linux. Hand-rolling shell scripts for docker ce installation drifts within weeks. Ansible's ansible.builtin.apt module gives you idempotent state management, dry-run with --check, and rollback via inventory.

Validation

ansible-playbook -i inventory/ubuntu-22-04.ini docker-ce-installation.yml --check --diff
ansible-playbook -i inventory/ubuntu-22-04.ini docker-ce-installation.yml

Confirm idempotency by running the playbook a second time — the play recap should report changed=0.

Troubleshooting

| Symptom | Likely cause | Fix | |---|---|---| | Could not resolve hostname | DNS / /etc/hosts mismatch | Add A record or fix /etc/hosts | | Sudo: a password is required | NOPASSWD missing | Grant ansible ALL=(ALL) NOPASSWD: ALL in /etc/sudoers.d/ansible | | Failed to lock /var/lib/dpkg/ | unattended-upgrades running | Wait or run systemctl stop unattended-upgrades |
