Problem running mongo and mongo-express in docker. What is the problem with docker-compose.yml file?

Question

This is my doocker-compose.yml file

version: '3.1'

services:

  mongo:
    image: mongo
    restart: always
    container_name: mongo
    environment:
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: example

  mongo-express:
    image: mongo-express
    restart: always
    depends_on:
      - mongo
    ports:
      - 8081:8081
    environment:
      ME_CONFIG_MONGODB_ADMINUSERNAME: root
      ME_CONFIG_MONGODB_ADMINPASSWORD: example

When i run $ sudo docker-compose up I get the following ...

I have tried to manually create network, expose ports, change names, bing ports to host, change ports etc... The most fanny thing that this example taken from https://hub.docker.com/_/mongo. The only thing I've added was

    depends_on:
      - mongo

I also tried to add environment variable for mongo-express ME_CONFIG_MONGODB_SERVER=mongo but it is default one so did't work ;(

Any suggestions?

you are just getting the mongod output. And seems to be complaining exactly about the line you added...Just check what's that doing. — Minsky, Nov 11 '20 at 21:48

You are using version 3.1 of compose. Either update that version to 3.8 and use docker-compose networks like this:

version: '3.8'

services:
  mongo:
    image: mongo
    restart: always
    environment:
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: example
    networks:
      - mongo-net
  mongo-express:
    image: mongo-express
    restart: always
    networks:
      - mongo-net
    ports:
      - 8081:8081
    environment:
      ME_CONFIG_MONGODB_ADMINUSERNAME: root
      ME_CONFIG_MONGODB_ADMINPASSWORD: example
networks:
  mongo-net:
    driver: bridge

Or use links with version 3.1 like this:

version: '3.1'

services:

  mongo:
    image: mongo
    restart: always
    environment:
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: example
  mongo-express:
    links:
      - "mongo"
    image: mongo-express
    restart: always
    ports:
      - 8081:8081
    environment:
      ME_CONFIG_MONGODB_ADMINUSERNAME: root
      ME_CONFIG_MONGODB_ADMINPASSWORD: example

In both cases you should see something like this in your mongo-express logs:

mongo-express_1  | Welcome to mongo-express
mongo-express_1  | ------------------------
mongo-express_1  | 
mongo-express_1  | 
mongo-express_1  | Mongo Express server listening at http://0.0.0.0:8081
mongo-express_1  | Server is open to allow connections from anyone (0.0.0.0)
mongo-express_1  | basicAuth credentials are "admin:pass", it is recommended you change this in your config.js!
mongo-express_1  | Database connected
mongo-express_1  | Admin Database connected

Thank you for answering! But unfortunately nothing has changed :( In both cases I get the same error – Maksym Antoshkin Nov 12 '20 at 09:07
What is your docker-compose version? `docker-compose version` – mehrdadep Nov 12 '20 at 12:42
When I run docker-compopse version I get the following `docker-compose version 1.27.4, build 40524192 docker-py version: 4.3.1 CPython version: 3.7.7 OpenSSL version: OpenSSL 1.1.0l 10 Sep 2019` – Maksym Antoshkin Nov 12 '20 at 15:14
and what about `docker --version`? – mehrdadep Nov 12 '20 at 16:24
Docker version is 19.03.13, build 4484c46d9d – Maksym Antoshkin Nov 12 '20 at 18:04
Just tested with your version of docker-compose and docker engine with the first compose file (version 3.8) and it works fine. Use these command and try again. `docker-compose down` - `docker container prune` - `docker network prune` – mehrdadep Nov 12 '20 at 18:51
And if by problem you mean the connection refused before mongo service is up and listening I must tell that's not a problem. That is the normal behavior. If you want to avoid mongo-express from even trying, use `wait-for-it` shell commands – mehrdadep Nov 12 '20 at 19:08

Problem running mongo and mongo-express in docker. What is the problem with docker-compose.yml file?
