I get an opcode error when trying to connect to a vanilla mongodb docker container from windows robo3t

Question

I'm using Windows 10 to develop Linux applications using Docker for Windows. I'm also using docker-compose. When I try to connect to a vanilla MongoDB 4.1 image from my Windows Robo 3T client, I get this peculiar error.

docker-compose.yml

version: "3"
services:
  myapp-db:
    image: mongo:4.1
    ports:
      - 27017:27017
    networks:
      - myapp-net
    volumes:
      - vol-myapp-db:/data/db
    restart: always

networks:
  myapp-net:

volumes:
  vol-myapp-db:

When I run this configuration I get the following error only when I attempt to connect with Robo3T.

stdout:

$ docker-compose up --build

Anyone have an idea what's going on here?

Answer 1

I used to have the same error with robo 3T 1.2.1

I updated the robo 3T version to 1.3 and it worked again,
which uses the MongoDB Internal Client 4.0:

{ 
  application: { name: "MongoDB Shell" },   
  driver: { name: "MongoDB Internal Client", version: "4.0.5-17-gd808df2233" }
} 

But as stated on their website they only recommend up to Mongo 4.0.

Robo 3T 1.3 brings you support for MongoDB 4.0 and SCRAM-SHA-256, an upgraded mongo shell, support for importing from MongoDB SRV connection strings, among many other fixes and improvements.

So i recommend using Studio 3T.
