Linux: systemd сервис для Docker Compose

Есть Docker Compose файл, который запускает Prometheus стек.

Рабочий каталог Prometheus – /opt/prometheus, в котором находится Compose файл prometheus-compose.yml.

Для управления им через systemd – создаём файл /etc/systemd/system/prometheus.service:

[Unit]
Description=Prometheus stack
Requires=docker.service
After=docker.service

[Service]
Restart=always
WorkingDirectory=/opt/prometheus

ExecStart=/usr/local/bin/docker-compose -f prometheus-compose.yml up

ExecStop=/usr/local/bin/docker-compose -f prometheus-compose.yml down

[Install]
WantedBy=multi-user.target

Проверяем.

Запускаем:

[simterm]

# systemctl start prometheus.service

[/simterm]

Проверяем контейнер:

[simterm]

# docker ps
