Run multiple containers on same docker network localhost

I want to connect from my app to mongodb on localhost, so they need to have same localhost address.

So the question is: Can two containers share they localhost, or for each container the localhost ip must be different?

  • docker compose with swarm and spring boot, cannot connect to database on different node
  • Docker containers cannot connect through overlay networks
  • Google Container Engine: Accessing Cloud Storage
  • Sharing /tmp between two containers
  • web api on docker stops
  • Docker + Spring Boot Error : could not create Vfs.Dir from url
  • I’m doing this for test environment purposes, so I don’t want in-memory database, changed mongo uri or any different solution. I just want to connect from A to B by localhost.

    To run my network and containers i type:

    docker network create --driver bridge isolated_nw
    docker run --name mongodb -d -p 27017:27017 --network=isolated_nw mongo:3.4.2
    docker run --name roomate-profiles --network=isolated_nw -d -p 8080:8080 sovas/roomate-profiles

    My custom docker network:

            "Id": "3efd6831784c2a8c9e9ea345144fcc6b9180e70c0e1b4b5d1a72219051b24e67",

    localhost won’t work since it refers to the roomate-profiles container. But you can do

    since both containers are connected to the same network. There is also no need to map the mongodb port to the host (unless you need it for something else).

    Docker will be the best open platform for developers and sysadmins to build, ship, and run distributed applications.
