Podman Desktop and the Virtual Learning Environment

[Vinny_Edivan]

I cannot seem to get the podman desktop command to work from the command line in the Lab environment. Is there a reason for this? This picture is right after completely recreating a lab environment and trying again. I know the podman desktop icon is under the activities in the top left and that works fine, but I also don't know if that opens podman as the current logged in user or as the student@workstation user. I also would like to know if there is a disconnect in podman desktop between registries and container images. As I can add a custom registry and login (so it seems) but cannot pull and image for some reason. Any advice would be great. Thank you

Hello

1)Answer for First part of question is simple: At Lab Environment Podman-Desktop installed only at workstation, but not at servers

2) More difficult second part of question. Without additional manipulation Podman Desktop on workstation could not login to registry.lab.example.com. Please, explain how you get your second screenshot

I am going through the RH134 training V9.3. This was released quite recently and has training on podman desktop. I reached the second screen shot by opening the podman desktop app in the lab environment and then going to settings in the bottom left and then the registries tab. Then clicked add custom registry and and tried to add the registry.lab.example.com registry and login. But no dice it seems. The answers about it only being on the workstation was very helpful though. Thank you.

What lab is this? You've put this in the RH134 section, but I can't find a lab that uses the containers-lifecycle script). It may be that you are using a version of RH134 that's not available to the Red Hat Academy (yet).

Anyway, the answer is most likely in your third screen shot:

It appears that you aren't logged into (authenticated to) registry.lab.example.com.

I don't know if the start script was supposed to log you into the registry - there's no output that suggests that it does. Perhaps the instructions give you a username and password to use? At the command prompt, use either:

podman login registry.lab.example.com (and then suply the information)

or

podman login -u <username> -p <password> registry.lab.example.com

Since you are logged into the contsvc user, try using contsvc as the <username> and contsvc's password as <password>.

I am going through the RH134 training V9.3. This was released quite recently and has training on podman desktop. I understand how to login to the registry from the command prompt. Just wanted to see more of the podman desktop. Thank you
