copenhagen-a had Ubuntu's docker-compose-v2 package installed, which
conflicts with Docker's official docker-compose-plugin over
/usr/libexec/docker/cli-plugins/docker-compose.
Moved the removal task before the install task and added docker-compose-v2
to the removal list.
* Add Docker official apt repo to docker role
The docker role was installing docker-compose-plugin which is only
available from Docker's official apt repository. helsinki-a had it
configured manually, but london-b and copenhagen-a did not, causing
deploy failures.
Now the role:
- Adds Docker's GPG key and apt repo (handles both Debian and Ubuntu)
- Installs docker-ce, docker-ce-cli, containerd.io, docker-compose-plugin
- Removes conflicting stock packages (docker.io, docker-compose)
* fix: resolve yamllint violations in docker role
- Remove standalone comment blocks that caused indentation errors
- Collapse multiline repo string to single line
- Ensure document start marker is present
* fix: keep all lines under 160 chars for yamllint
Use set_fact to build the Docker repo line in parts instead of
one long inline string.
* fix: resolve yamllint errors in london-b host_vars and promtail config
- Remove trailing blank line in inventory/host_vars/london-b.yml
- Add missing document start marker to promtail config
- Fix indentation in promtail scrape_configs (indent list items under key)
* Remove ansible-lint on push, keep PR-only
Lint already runs on pull_request — no need to double up on push to main.
- Docker role: replace docker-compose with docker-compose-plugin (v2).
The old docker-compose package conflicts with docker-compose-plugin
already installed on helsinki-a. Also removes the conflicting package
if present.
- firewall_alpine handler: use ansible.builtin.shell instead of
ansible.builtin.command for iptables-restore, since the redirect
operator (<) requires a shell.
