In some cases the bracket from the prompt gets passed which locks the terminal

Working in the last section of the lab. Got an error msg regarding fail to connect to DB.

I did not get any error msg from the log:

I am working on the lab3 to push the image locally to Openshift. It looks like the project is not set, not even to the default.

[lab-user@studentvm 0 ~]$ oc project
No project has been set. Pass a project name to make that the default.

So I got an error when I executed the following command

[lab-user@studentvm 0 ~]$ sudo podman tag localhost/wordpress $OS_REGISTRY/$(oc project -q)/w
ordpress
error: no project has been set
Error: error adding 'default-route-openshift-image-registry.apps.summit2021.openshift.open.re
dhat.com//wordpress' to image "localhost/wordpress": invalid reference format

There's a potential issue if a user accidentally pulls an image from dockerhub and ends up with a localhost image and another registry image. This was observed in some cases with the mariadb container image.

Fully qualifying all of the podman run commands with the localhost-based tag will fix the issue even if the user has the extra image present.

I tried to create a pod following the instructions in lab, but got weird error. Here are the details:

[lab-user@studentvm 0 ~/workspace/mariadb/openshift]$ ls -l
total 4
-rw-r--r--. 1 lab-user users 392 Sep 24 18:49 mariadb-pod.yaml

[lab-user@studentvm 0 ~/workspace/mariadb/openshift]$ oc create -f mariadb-pod.yaml
error: unable to recognize "mariadb-pod.yaml": Unauthorized
[lab-user@studentvm 1 ~/workspace/mariadb/openshift]$

The file is there and it seems to have the right privilege, but I got the error:

error: unable to recognize "mariadb-pod.yaml": Unauthorized

From the prompt, it looks like it switch between vms? It changed from [lab-user@studentvm 0] to [lab-user@studentvm 1]?

oc whoami --show-console will get them the URL and then they can login

Current location: Check Your Project

"Under the covers, this cluster has an Operator that will automatically create a default project for your user after you first login. This is not instantaneous, so, before continuing, make sure that the default project exists. Execute the following:"

Needed location: OpenShift Projects and Namespaces

Issue: The tagging op under Tag Images for Registry assumes that the project is created and set. If the user logins in to ocp AND tags the Wordpress image fast enough, the tagging will fail.
