Errors running Container Tutorials

[tshawker]

In which scenario did this bug occur?

Linux Container Internals 2.0 - Lab 2: Container Images

At what step of the scenario did this happen?

First (start of tutorial)

Describe the bug

Example commands fail to execute.

1. "conmon" package is out of date.
2. No such container image, registry.access.redhat.com/ubi7/ubi:latest
3. No such container image, registry.access.redhat.com/ubi7/ubi_minimal:latest

Logs or error messages

1. conmon
   [root@bc02dd8781de ~]# podman pull registry.access.redhat.com/ubi7/ubi
   WARN[0000] Conmon at /usr/bin/conmon invalid: outdated conmon version
   WARN[0000] Conmon at /usr/bin/conmon is invalid: outdated conmon version

To proceed, I updated conman with "yum upgrade conmon"

2. images
   [root@bc02dd8781de ~]# podman history registry.access.redhat.com/ubi7/ubi:latest
   Error: registry.access.redhat.com/ubi7/ubi:latest: image not known
   [root@bc02dd8781de ~]# podman history registry.access.redhat.com/ubi7/ubi-minimal:latest
   Error: registry.access.redhat.com/ubi7/ubi-minimal:latest: image not known

It looks as if the installation script doesn't download the images. I ran step 3, which updates the ubi7 image, and that retrieves the image before updating it. The first command that shows the image history then works, but the second that looks at the minimal image continues to fail. I manually downloaded the minimal image and the sample command then worked.

Moving on to another scenario, it seems that the failure with "conmon" breaks the downloads of the various images. I have to manually upgrade conmon and then rerun all the downloads. That seems to work.
