I have a docker configuration where I started nginx server. Now I have to run mongo and mongo-express to be able to connect to my database. When I put my configuration for those two in docker-compose.yml and try docker compose up, mongo service starts but mongo express shows this error
Could not connect to database using connectionString: mongodb://root:pass@mongodb:27017/" mongo-express_1 | (node:8) UnhandledPromiseRejectionWarning: MongoNetworkError: failed to connect to server [mongodb:27017] on first connect
Any help is appreciated, here are my configurations.
