Deploying stacks using the "Docker Application Bundle" (`.dab`) file format was introduced as an experimental feature in Docker 1.13 / 17.03, but superseded by support for Docker Compose files in the CLI. With no development being done on this feature, and no active use of the file format, support for the DAB file format and the top-level `docker deploy` command (hidden by default in 19.03), will be removed from the CLI, in favour of `docker stack deploy` using compose files. This patch removes the `docker-compose bundle` subcommand from Docker Compose, which was used to convert compose files into DAB files (and given the above, will no longer be needed).

Docker Compose
❗ The docker-compose project announces that as Python 2 reaches it's EOL, versions 1.25.x will be the last to support it. For more information, please refer to this issue.
Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a Compose file to configure your application's services. Then, using a single command, you create and start all the services from your configuration. To learn more about all the features of Compose see the list of features.
Compose is great for development, testing, and staging environments, as well as CI workflows. You can learn more about each case in Common Use Cases.
Using Compose is basically a three-step process.
- Define your app's environment with a
Dockerfileso it can be reproduced anywhere. - Define the services that make up your app in
docker-compose.ymlso they can be run together in an isolated environment. - Lastly, run
docker-compose upand Compose will start and run your entire app.
A docker-compose.yml looks like this:
version: '2'
services:
web:
build: .
ports:
- "5000:5000"
volumes:
- .:/code
redis:
image: redis
For more information about the Compose file, see the Compose file reference.
Compose has commands for managing the whole lifecycle of your application:
- Start, stop and rebuild services
- View the status of running services
- Stream the log output of running services
- Run a one-off command on a service
Installation and documentation
- Full documentation is available on Docker's website.
- Code repository for Compose is on GitHub.
