Why does the mongo-express-service external service in my browser require a username and password?

Question

I am currently working through the following Kubernetes tutorial: https://www.youtube.com/watch?v=X48VuDVv0do&t=2437s&ab_channel=TechWorldwithNana

I am using an 2022 Macbook Air with an M2 chip, so Hyperkit is not compatible, so instead I am using Qemu. My problem is this: when I run the external service 'mongo-express-service' with Minikube, the browswer opens, but I am asked to sign in. See 1:44:40 of the video above to see which step I am on. I am using the exact files from Nana's repo, so I think it has something to do with me using Qemu and having to install socket_vmnet to run the external service. This is what I get in the browser when I run the external service. This is what I get in my terminal when I run the external service.

These are my files:

I have tried using 'username' and 'password' as well as their base64 encoded versions but that does not work. I have also tried going into the Qemu documentation to no avail.

It looks like everything is set up correctly and running, I just don't know why it is asking for authorization.

Answer 1

You need to enter credentials for the web login of the mongo-express container.

The default values for the first login are "admin" for username and "pass" for password. You can read it in mongo-express documentation here.
