Changed the wrong file at first, but fixed it now.

I get that we'd like to suggest an alternative.

• Why is this container image a good choice / could we switch to another image (maybe one that we, the
  Kubernetes project, control)?
• please specify the registry; corelab is not a DNS name that resolves.
  I know you mean Docker Hub, but some readers might not.

[azn-abel]

A better alternative may be us-docker.pkg.dev/google-samples/containers/gke/gb-frontend:v5, which is now the image used in the original tutorial.. Pasting the link in a browser leads to a Google cloud container registry.

A note could also be added at the top of the .yaml file directing readers to the original tutorial's yaml file if they have run into any trouble with the container image.

If this works, I will update the PR accordingly.

@azn-abel I like this option. If we can get the page corrected, it will help resolve many duplicate issues which have been logged for this.

Sounds good. I've corrected the page in a new commit @adityasamant25

[adityasamant25]

@azn-abel Looks good to me. However I don't have the permissions to add the lgtm label. Can you please request one of the other reviewers to help?
Also would be great if you could squash the commits into one.

[azn-abel]

@adityasamant25 Thanks - I've squashed the commits. I'll request @sftim for the lgtm label.

[adityasamant25]

Looks good to me.

Per #44290 (comment)

Why is this container image a good choice / could we switch to another image (maybe one that we, the Kubernetes project, control)?

We'll need an answer to that question.

@sftim

• The image is a good choice because it's the image that's now used in the original tutorial that the one on k8s.io is based on, and it works well with the rest tutorial. The previous image used was also Google's, but they seem to have taken it down in favor of this updated one.
• The Kubernetes project doesn't seem to own any compatible images, as the images used in the tutorial (aside from the redis image) are both controlled by Google. Unless we can upload copies of the images to a registry owned by the Kubernetes project the Google ones may be the best option.
• Also looks like Google replaced the gb-redis-follower currently referenced in the k8s.io tutorial (gcr.io/google_samples/gb-redis-follower:v2) with us-docker.pkg.dev/google-samples/containers/gke/gb-redis-follower:v2. I can go ahead and update this one as well in case the older one is taken down.

Hi folks – SIG Docs has PR wranglers assigned each week in order to move through the contribution queue of PRs, of which the schedule can be found here: https://github.com/kubernetes/website/wiki/PR-Wranglers

Feel free to ping the relevant PR wrangler in a PR, or in the #sig-docs channel on Kubernetes Slack, to have your work looked at as needed. I can see with the scheduling that Tim has already given his review, and I'm on schedule next week. Unfortunately, the assigned reviewers have yet to respond.
