Error Pulling Container

Jump to solution

I am currently undertaking version 4.14 of the DO188 - Red Hat OpenShift Development I: Introduction to Containers with Podman. In https://rol.redhat.com/rol/app/courses/do188-4.14/pages/ch02s03 (chapter 2, section 3) I am trying to follow the Container Networking Basics interactive, however, upon executing the second command:

podman run -d --name my-container \--net example-net container-image:latest

 or alternatively:

podman run -d --name my-container \
--net example-net container-image:latest

 and also:

podman run -d --name my-container --net example-net container-image:latest

 It first gives me an option to select the following:

In terms of self-troubleshooting here is the following that I have tried:

  1. I have tried to login using the following commands using my username and password:
    podman login registry.redhat.io
    podman login reigstry.access.redhat.com

    ## With user name jlumagbas, which succeeds
    Whilst I am successful in logging in, it does not seem to solve any of the issues I face.
  2. Restarting the laboratory environment: I have tried this multiple times and have even destroyed and re-created the environment several times but no luck.

I hope there is a fix out there that can help me as I would like to proceed with the course.

You aren't doing a guided exercise. You are looking at the lecture content. You can't always type what is in a lecture. In this instance 

container-image:latest

Isn't a real container image which is why you can't pull it down from the registry. You must be logged into a container registry and you must also use a real container image with a real tag.

You can only perform Guided Exercises and End of Chapter labs in our Red Hat Training courses and not all of the lecture items have commands you can directly copy/paste. They are representations and in this instance "Container Name" is meant to be the name of a container.
