Add support for tuning the start of linked services
Background: https://github.com/docker-library/docker/pull/12
Executor: docker
Some images needs entrypoint arguments instead of environment variables to configure the service. Unfortunately this is needed for the docker:dind
image. So when an user wants to pass a custom docker registry mirror, he needs at the moment an patched version of this image to support an environment variable.
The current approach to configure services looks like this:
job:
services:
- postgres:9.5
- redis:3.2
I would like to see an ability to configure starting options like docker-compose.yml
supports.
It could look like this:
job:
services:
"docker:dind":
command: --registry-mirror=http://mymirror:6000
There could be also an environment
array node to configure specific environment variables only for this service. (To stop pollution on environment variables on all related containers)
job:
services:
"docker:dind":
command: --registry-mirror=http://mymirror:6000
"postgres:9.5":
environment:
POSTGRES_USER: postgres
POSTGRES_PASSWORD: postgres
What do you think about it?
