Docker Compose Plugin

With the Release Docker Compose plugin you can create and destroy multi-container Docker applications on a Docker host.

It includes the following task types:

  • Docker Compose: Up
  • Docker Compose: Start
  • Docker Compose: Stop
  • Docker Compose: Down
  • Docker Compose: Command

In the release flow editor, Docker Compose tasks are marked with a blue border.

Features​

  • Create and start containers and services on a Docker host
  • Stop containers and services on a Docker host
  • Remove containers, networks, images, and volumes on a Docker host

Requirements​

The Docker Compose plugin requires the Release Remoting plugin to be installed.

Set up a Docker Compose server​

To set up a connection to a Unix server running Docker Compose:

In Release, from the navigation pane, go to Configuration> Connections and click Add Unix Host.

  1. In the Address box, enter the IP address or host name of the remote machine running Docker Compose.

  2. In the Port box, enter the SSH port of the remote machine.

  3. In the Username and Password boxes, specify the user name and password of the SSH user that Release should use when connecting to the remote machine.

  4. In the Sudo Username box, enter the user name of the sudo user on the remote machine (for example, root).
