Name: nginx-app
Using container nginx with version 1.11.10-alpine
The deployment should contain 3 replicas
Next, deploy the application with new version 1.11.13-alpine, by performing a rolling update.
Finally, rollback that update to the previous version 1.11.10-alpine.

I thought 1.11.13 had some bugs, so rollback makes sense.

Wait, why rollback to 1.11.10? Isn’t 1.11.13 better?

Rolling update to 1.11.13-alpine was smooth!

I think I saw a question like this in our mock exams. The deployment should be straightforward, but I need to double-check the versioning for the update and rollback.

I feel confident about setting up the initial deployment, but rolling back is a bit fuzzy for me. I hope I can remember the rollback command!

I think the rolling update part is similar to what we did in the last session, but I can't recall the exact syntax for the kubectl command.

I remember we practiced creating deployments with specific replicas, but I'm not sure about the exact command for the rolling update.

Alright, time to put my Kubernetes skills to the test. I'll start by creating the deployment, then use the rolling update functionality to upgrade to the new version, and finally roll it back to the previous version. Gotta love those Kubernetes commands!

No problem, I've got this. I'll use `kubectl create deployment` to set up the initial deployment, then `kubectl set image` to update to the new version, and finally `kubectl rollout undo` to roll it back. Easy peasy!

Whoa, this is a tricky one. Updating and rolling back a deployment? I'm not sure I've practiced this before. Let me think through the steps carefully and make sure I don't mess anything up.

Hmm, okay, I think I can handle this. First, I'll need to create the deployment, then update it to the new version, and finally roll it back. Shouldn't be too difficult, just need to remember the right commands.

This looks like a straightforward deployment and update question. I'll start by creating the initial deployment with 3 replicas of the nginx:1.11.10-alpine container.

Wait, are we allowed to use kubectl? I was planning on just manually editing the YAML files. I hope that's not against the rules...

Don't worry, using kubectl is allowed and it's the recommended way to manage deployments.

It's more efficient to use kubectl for these tasks, rather than manually editing YAML files.

Yes, you can use kubectl to create the deployment and perform the rolling update.

Looks good! The key steps are creating the initial deployment, then updating the image to the new version, and finally rolling back to the previous version. Shouldn't be too difficult.
