Playbook под все хосты из твоего inventory, который установить Docker&Compose

Что делает этот PlayBook

  • ставит Docker CE из официального репозитория (Debian/Ubuntu и RHEL/CentOS 8/9);

  • добавляет пользователя kodalin в группу docker и корректно обновляет сессию;

  • ставит Docker Compose (v2) именно из GitHub docker/compose — всегда самую последнюю стабильную (через GitHub API);

  • кросс-архитектурный: x86_64, aarch64, armv7, ppc64le, s390x;

  • аккуратно, идемпотентно, без устаревших apt_key/bionic/ручного compose v1.

Сохрани как, например, docker-install.yml и запускай:

ansible-playbook -i inventory.ini docker-install.yml

Предпосылки: на контрол-ноде установлен Ansible; на целевых — интернет к download.docker.com и github.com. Если у тебя другие sudo/SSH-настройки — поправь remote_user/инвентори.

Заметки:

  • Если какой-то хост — ARM/IBM Z/PowerPC — арх маппинг уже учтён. Для экзотических платформ, которых нет в релизах compose, таск «Fail on unsupported architecture» остановит плей.

  • Проверка hello-world выполняется от лица текущего SSH-пользователя (kodalin) уже после reset_connection, поэтому права группы docker применяются корректно.

  • При желании можно закрепить конкретную версию compose: -e "compose_version=v2.31.0".
