Microk8s Kubernetes and connecting by Service Name

Ops and Admin

Hi Folks

I have gotten my app running with Docker and all works well.

I have now attempted to put it in kubernetes and experiencing problems to understand how to do this.

When I use docker I can connect with mongosh using the host name passed

docker run -d --rm --name mongo -p 27017:27017 -v mongodata -e MONGO_INITDB_ROOT_USERNAME=forshow -e MONGO_INITDB_ROOT_PASSWORD=forshow --network restapicsharp mongo

And in this case I can connect with the user/password and the name of the container (mongo) and all works well.

For Kubernetes I am instructed to use the service-name and Cluster :None and the forums say do not command.

If I use mongo client I can connect to the kubernetes service as long as I do not use the user/password

mongosh mongodb://mongodb-service:27017

if I try with the username/password

mongosh mongodb://forshow:forshow@mongodb-service:27017

It fails with MongoServerError: Authentication failed.

And of course "UserNotFound: Could not find user …

I do specify the user and password

    env:
    - name: MONOGO_INITDB_ROOT_USERNAME
      value: "forshow"
    - name: MONOGO_INITDB_ROOT_PASSWORD
      value: forshow

And as I say with no credentials it does work.

Thanks all
