How to stop all containers when one container stops with docker-compose?
Solution 1:
You can use:
docker-compose up --abort-on-container-exit
Which will stop all containers if one of your containers stops
Solution 2:
In your docker compose file, setup your test driver container to depend on other containers (with depends_on
parameter). Your docker compose file should look like this:
services:
application_server:
...
selenium:
...
test_driver:
entry_point: YOUR_TEST_COMMAND
depends_on:
- application_server
- selenium
With dependencies expressed this way, run:
docker-compose run test_driver
and all the other containers will shut down when the test_driver
container is finished.
This solution is an alternative to the docker-compose up --abort-on-container-exit
answer. The latter will also shut down all other containers if any of them exits (not only the test driver). It depends on your use case which one is more adequate.
Solution 3:
Did you try the work around suggested on the link you provided?
Assuming your test script looked similar to this:
$ docker-compose rm -f
$ docker-compose build
$ docker-compose up --timeout 1 --no-build
When the application tests end, compose would exit and the tests finish.
In this case, with the new docker-compose
version, change your test container to have a default no-op command (something like echo, or true), and change your test script as follows:
$ docker-compose rm -f
$ docker-compose build
$ docker-compose up --timeout 1 --no-build -d
$ docker-compose run tests test_command...
$ docker-compose stop
Using run allows you to get the exit status from the test run, and you only see the output of the tests (not all the dependencies).
Reference
If this is not acceptable, you could refer to Docker Remote API and watch for the stop
event for the containers and act on it.
An example usage is this docker-gen tool written in golang
which watches for container start events, to automatically regenerate configuration files.
