Installing and Using docker-compose

- Using Docker Compose with Docker Executor
docker-compose utility is pre-installed in the CircleCI convenience images. If you’re using another image, you can install it into your primary container during the job execution with the Remote Docker Environment activated by adding the following to your
- run: name: Install Docker Compose command: | curl -L https://github.com/docker/compose/releases/download/1.19.0/docker-compose-`uname -s`-`uname -m` > ~/docker-compose chmod +x ~/docker-compose sudo mv ~/docker-compose /usr/local/bin/docker-compose
Then, to activate the Remote Docker Environment, add the
This step enables you to add
docker-compose commands to build images:
Or to run the whole system:
docker-compose up -d
In the following example, the whole system starts, then verifies it is running and responding to requests:
- run: name: Start container and verify it's working command: | set -x docker-compose up -d docker run --network container:contacts \ appropriate/curl --retry 10 --retry-delay 1 --retry-connrefused http://localhost:8080/contacts/test
Note: The primary container runs in a separate environment from Remote Docker and the two cannot communicate directly. To interact with a running service, use docker and a container running in the service’s network.
Using Docker Compose with Machine Executor
If you want to use docker compose to manage a multi-container setup with a docker-compose file, use the
machine key in your
config.yml file and use docker-compose as you would normally. That is, if you have a docker-compose file that shares local directories with a container, this will work as expected. Refer to Docker’s documentation of Your first docker-compose.yml file for details. Note: There is an overhead for provisioning a machine executor as a result of spinning up a private Docker server. Use of the
machine key may require additional fees in a future pricing update.
Using Docker Compose with Docker Executor
docker combined with
setup_remote_docker provides a remote engine similar to the one created with docker-machine, but volume mounting and port forwarding do not work the same way in this setup. The remote docker daemon runs on a different system than the docker CLI and docker compose, so you must move data around to make this work. Mounting can usually be solved by making content available in a docker volume. It is possible to load data into a docker volume by using
docker cp to get the data from the CLI host into a container running on the docker remote host.
This combination is required if you want to build docker images for deployment.
See the Mounting Folders section of the Running Docker Commands for examples and details.
