Can't connect to MongoDB running in docker container

I run MongoDB in a docker container like this

docker run --name mongo -d -p 27017:27107 mongo

Check with docker ps shows

77f1a11295c3 mongo "docker-entrypoint.s…" 20 minutes ago Up 20 minutes 27017/tcp, 0.0.0.0:27017->27107/tcp mongo

so it's running with the port mapped correctly.

When I try to setup a connection via Intellij

it fails with

com.mongodb.MongoTimeoutException: Timed out after 10000 ms while waiting to connect. Client view of cluster state is {type=UNKNOWN, servers=[{address=localhost:27017, type=UNKNOWN, state=CONNECTING, exception={com.mongodb.MongoSocketReadException: Exception receiving message}, caused by {java.net.SocketException: Connection reset}}].

When I try to connect to connect from a golang web server

clientOptions := options.Client().ApplyURI("mongodb://localhost:27017")
client, err := mongo.Connect(context.TODO(), clientOptions)

I get this error and it shuts down the web server:

server selection error: server selection timeout, current topology: { Type: Unknown, Servers: [{ Addr: localhost:27017, Type: Unknown, Average RTT: 0, Last error: connection() error occured during connection handshake: connection(localhost:27017[-64]) incomplete read of message header: read tcp 127.0.0.1:40700->127.0.0.1:27017: read: connection reset by peer }, ] }

Is this a bug in the MongoDB docker image, or is there something else I need to do?

I think you have a typo mistake while creating a container. 27017 and 27107

docker run --name mongo -d -p 27017:27017 mongo

This is clearly visible in docker ps command.

Can you try and see if it solves the problem ?

As @fly2matrix said you have a typo, and I believe you have another issue:

1. you forward the ports 27017:27107, in which the container port is incorrect. Check 27107 instead of 27017
2. It seems you're connecting to localhost instead of mongo as I see the phrase localhost in your code.
