Your docker-compose log output only shows the one error message from Mongo-Express? What're the logs for the Mongodb container? when I tried it took 5 connection attempts and then connected successfully docker-compose logs$ docker logs mongo_mongo-express_1

Can you do a version: '3.1'
services:
mongo:
image: mongo
restart: always
environment:
MONGO_INITDB_ROOT_USERNAME: root
MONGO_INITDB_ROOT_PASSWORD: example
mongo-express:
image: mongo-express
restart: always
ports:
- 8081:8081
environment:
ME_CONFIG_MONGODB_ADMINUSERNAME: root
ME_CONFIG_MONGODB_ADMINPASSWORD: example
ME_CONFIG_MONGODB_URL: mongodb://root:example@mongo:27017/
restart: unless-stoppedIt should give this output. And hopefully with a $ docker-compose up -d
Creating network "temp_default" with the default driver
Creating temp_mongo-express_1 ... done
Creating temp_mongo_1 ... done
$ docker run -it --rm --network=temp_default mongo mongosh mongodb://root:example@mongo:27017

I had the same issue. Looking at the logs from the mongo-express container gave me the correct credentials to log in. Seems as though the env vars for admin username and password are ignored for mongo-express config. Mongo Express server listening at http://0.0.0.0:8081 |

I am simply running
docker-compose up -dusing the compose file found on the docker page of mongo (https://hub.docker.com/_/mongo/) under the title "... via docker stack deploy or docker-compose"docker-compose.yml:
Output of running docker-compose logs
Waiting for MongoDB to start up wasn't the issue. It was still failing to connect after 10 minutes
Any ideas how to fix this? Host machine is running Ubuntu.
