My situation. Trying to run a docker-compose structure several times on the same box. This is my docker-compose.yml:
version: '3'
services:
code:
image: organization:java-maven
links:
- mysql:mysql
volumes:
- "${PWD}:/home/ubuntu/src"
mysql:
image: organization:mysql
Running this twice with docker-compose run code mvn clean test creates two containers of code and one container of mysql.
Now, I want one code to be linked to one mysql, and another code linked to another mysql.
How do I accomplish this? This is supposed to run on jenkins slaves and the maven executions cannot share mysql.
I've miserably failed trying with the "-e KEY=VALUE" option for docker-compose run together with container_namein the docker compose file.
Not sure how to approach this, please help, thank you.
So, I focused too much on using directives to alter container names manually. The solution was much easier.
docker-compose -p anything run code mvn clean test
docker-compose -p anything_else run code mvn clean test
So, this is the project name solution. Docker compose will use the value given with the option -p as a prefix when creating container names. That means no collision.
Very handy!
