Docker compose删除了另一个容器

Question

I have a project with one basic docker-compose.yml file and then 2 another file - each for one environment docker-compose.dev.yml and docker-compose.prod.yml .

docker-compose.yml

version: "2"

services:
    app:
        build: 
            context: .
        depends_on:
            - redis
            - selenium
        networks:
            - richy

    redis:
        image: redis:3.2
        container_name: redis
        networks:
            - richy

    selenium:
        image: selenium/standalone-chrome
        container_name: selenium
        networks:
            - richy

networks:
    richy:
        driver: bridge

docker-compose.dev.yml

version: "2"

services:
    app:
        build: 
            args:
                env: dev
        image: richy_image:dev-latest
        container_name: richy-dev
        volumes:
            - .:/var/www/richy
        ports:
            - 9000:80
        environment: 
            - ENV=dev

docker-compose.prod.yml

version: "2"

services:
    app:
        build: 
            args:
                env: prod
        image: richy_image:prod-latest
        container_name: richy-prod
        volumes:
            - /home/grafa/workspace/prichy/richy/db.sqlite3:/var/www/richy/richy/db.sqlite3
        ports:
            - 9001:80
        environment: 
            - ENV=prod

I run my dev/prod environments like docker-compose -f docker-compose.yml -f docker-compose.(dev|prod).yml up

The thing is I cannot run there both containers side by side despite I was able to do it like a month ago and few changes ago. Everytime I have running for example dev environment and I spawn docker-compose for prod environment docker spits out this:

redis is up-to-date
selenium is up-to-date
Recreating richy-dev

which is strange because why it wants to recreate the richy-dev container when I'm starting the richy-prod.

Maybe there is a conflict in my config files. Can you guys please help me?

Thank you.

Answer 1

Basically to differentiate between container names of two environments, you will need to define project name explicitly. otherwise it takes the name based on the folder name.

you can use -p or the COMPOSE_PROJECT_NAME environment variable for that.
