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:
However, choosing either one of them gives me the following errors:
Hence, I am unable to proceed with similar interactives in the course as I face the same errors.
In terms of self-troubleshooting here is the following that I have tried:
podman login registry.redhat.ioWhilst I am successful in logging in, it does not seem to solve any of the issues I face.
podman login reigstry.access.redhat.com
## With user name jlumagbas, which succeeds
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.
