How to run MongoDB and Mongo-express with docker-compose?

Question

I try to run MongoDB and Mongo-express by Docker-compose. I use following config:

version: \'3\'

services:
    mongo:
        image: mongo
        environment:
         


        

Answer 1

In case you are still having this issue... Or in case someone else is going absolutely crazy trying to figure out why none of this works...

Running docker-compose up --force-recreate

Doesn't recreate the container completely (not sure why) - it DOES look like it did, but I figured out that it wasn't recreating the container's data (databases!) when I got into the DB without Auth, and a collection that I created an hour ago was still there.

I had run the above command, and also 'docker image rm mongo' as well as removing the mongo-express (Not needed)

The problem is I had to do a 'docker container list' to see the two containers I had (one for Mongo by itself and one for Mongo with Mongo-express - not sure which I needed to delete, but I deleted them both...)

Once I did that, and did the 'up' your configuration pulling the values from the .env file worked fine - it did the INITDB... and set the Admin passwords correctly in the database!

So, if you EVER created it with any configuration to test it, you will have a container that it is reusing the data for (I think it doesn't recreate that to avoid data loss - I mean, 99.9% of the time you just want to recreate the PROGRAM part, not the data - otherwise you would lose your databases.)

Killed a couple hours figuring this one out...

Some updates in new verion of mongo-express, the accepted solution doesn't work any more, especially you need fix this issue

TypeError: Cannot read property 'listDatabases' of undefined

Tips

Do remember, if you adjust the setting, restart it with option --force-recreate.

docker-compose up --force-recreate -d

Here is the docker-compose.yml I am using currently.

version: '3'

services:
    mongo:
        image: mongo:${MONGO_TAG}
        environment:
            - MONGO_INITDB_ROOT_USERNAME=${MONGO_ROOT_USER}
            - MONGO_INITDB_ROOT_PASSWORD=${MONGO_ROOT_PASSWORD}
            - MONGO_INITDB_DATABASE=project
    mongo-express:
        image: mongo-express
        environment:
            - ME_CONFIG_MONGODB_SERVER=mongo
            - ME_CONFIG_MONGODB_PORT=27017
            - ME_CONFIG_MONGODB_ENABLE_ADMIN=true
            - ME_CONFIG_MONGODB_AUTH_DATABASE=admin
            - ME_CONFIG_MONGODB_ADMINUSERNAME=${MONGO_ROOT_USER}
            - ME_CONFIG_MONGODB_ADMINPASSWORD=${MONGO_ROOT_PASSWORD}
            - ME_CONFIG_BASICAUTH_USERNAME=${MONGOEXPRESS_LOGIN}
            - ME_CONFIG_BASICAUTH_PASSWORD=${MONGOEXPRESS_PASSWORD}
        links:
            - mongo
        ports:
          - "8081:8081"
