I’m not sure about rolling back, isn’t that risky?

Alyssa 11 months ago

Rolling updates are the way to go, no downtime!

Gladys 12 months ago

Wait, is 1.13 the latest version? I thought it was higher now.

Ressie 12 months ago

Totally agree, those settings are crucial for stability!

Amie 1 year ago

Just updated the deployment with maxSurge 5% and maxUnavailable 2%.

Rusty 1 year ago

I feel a bit confused about the namespace part. Do I need to specify it in every command, or just the ones for the deployment?

Rasheeda 1 year ago

Rolling back the deployment is something I practiced, but I can't recall the exact command. Was it `kubectl rollout undo`?

Beata 1 year ago

This seems similar to a practice question where we had to update an image version. I think I need to use `kubectl set image` for that part.

Lashon 1 year ago

I remember something about maxSurge and maxUnavailable settings, but I'm not entirely sure how to apply them in this context.

Salome 1 year ago

Alright, time to put my Kubernetes skills to the test. I'll need to use the right commands to update the deployment, do the rolling update, and then roll it back. Shouldn't be too bad if I take it step-by-step.

Lenora 1 year ago

Hmm, this looks like a tricky one. I'll need to review the Kubernetes deployment update and rollout commands to make sure I get this right. Gotta be careful with those percentages.

Hollis 1 year ago

Okay, let's see. I think I can handle this. I'll need to use the `kubectl set` command to update the deployment, and then `kubectl rollout` to perform the rolling update and rollback.

Honey 1 year ago

Oof, this is a lot of steps. Updating the deployment, rolling out a new version, and then rolling it back? I better double-check the syntax for those commands to make sure I don't mess anything up.

Yoko 1 year ago

Hmm, I'm a bit unsure about the differences between the options. I'll need to review my notes on the tax treatment of domestic, multinational, and nonresident life insurance companies in Canada.

I'm a bit confused about the specifics of LACP modes. I remember LACP Active is usually paired with protocols like LLDP, but is that right given CDP is off?

Lorrine 1 year ago

Based on my understanding, an agent is typically needed to integrate a k8s cluster with a monitoring or management solution. But I'd double-check the documentation to be sure.

I can already smell the Kubernetes vibes from this question. Let's crush it!

Let's roll out the new version of the web1 deployment with Ifccncf/ngmx image version 1.13.

Rolling back to the previous version is a crucial step, just in case the new one causes any issues.

Elke 2 years ago

Haha, 'Ifccncf/ngmx' - what a name! I wonder who came up with that.

Jettie 1 year ago

↳ replying to Elke

It's definitely a unique name for an image version, that's for sure.

Shawna 1 year ago

↳ replying to Elke

I wonder if the developers just mashed their keyboard to come up with that name.

I know right, 'Ifccncf/ngmx' sounds like a random combination of letters!

Looks good! The updated deployment settings should ensure a smooth rollout.

Yvonne 1 year ago

Now we just need to make sure the rollback to the previous version works smoothly.

Yes, the maxSurge and maxUnavailable percentages should help with the rollout.

Thanks! I'm glad the deployment settings look good.
