Went from "Oh Shit! we're screwed" to "Ah, this is fine" in 12 minutes.

200% clear, no more questions.. Great explanation.. Thank you..

As someone with a self managed and on-prem K8s cluster, I will say that changing the container runtime from docker to containerd was not only fairly straight forward, but I'm also noticing better node resource availability which makes sense given the heaviness of dockershim vs natively supported cri. I will say, the process to change runtimes was not well documented as of yet, but if anyone needs assistance and is also using kubdadm to manage their on-prem clusters, just hit me up!

Nana, you are the best to explain the change, I was boiling the ocean to understand the change, but you nailed it in 12 min. Thanks a lot, keep up the good work. always following you.

[kenchang]

Whew, thank you for this video! As a newbie using docker for development this took a load off my mind.

[SanjayKumar-rfkh]

Just brilliant Nana. Keep up the good work !. I have referred a couple of your videos and became your big fan. The way you explain the concept is just amazing. God bless you.

[mytubeuser]

No matter how difficult or confusing the subject may be, Nana knows the way to break it down to make super duper easy. My 2 year old has no further questions, so do I :) Thanks Nana...

[danielyount]

Thanks for the rundown of the cluster changes. Having to fight to find documentation for setting a local private K8 cluster, I was set a back that this was going to be a bad thing. But with your explanation, sound like it will be smooth sailing. I would take this as a advantage to move Docker closer to the top of the stack. Containers are very slow compared to VM's(around half speed. You want VM's over containers for time sensitive services) So to take out another layer of slowness would be a bonus, if you choose the container option. If for some reason you still need the shim, it's an option.

i wish i had discovered this channel earlier ... you got yourself a new subscriber

[smitshah]

Now I am cristal clear about changes! Thanks, Tina!

[pazonec]

So comprehensive and clear! If you can explain it simply, you understand it perfectly...

[ebenessy]

It's the first time I see your channel and I'm really impressed by the quality of your explanations and the way you're presenting them. Pleased continue this great work. Thank you.

[tarasankarbanerjee]

Excellent as always!! How do you anticipate all the questions that can arise!! Just awesome..

[Joe-tkcx]

Perfect explanation, just the thing I needed, just as request, can you do a tutorial on crio or containerd.

[ravindrav]

My most productive 12.21 minutes of today; Thank you Nana :-)

[tilmow]

Yet another cristal clear straight to the point video, bravo! which leaves me begging for others, specifically on the container runtime landscape.
I understand CRI-O or containerd can only replace Docker **within** kubernetes as container runtime, i.e that can't be used to build or run a standalone containerized workload --> is that correct?
more generally, some intro videos on docker alternatives will be more than welcome : how to install them to set-up a k8S cluster, how to configure the latter accordingly, how do they work ... etc.
Thanks again for the great content

[manikanthanekkalapudi]

Thank you Nana! Such a simple explanation🙏 Subscribed!

[Farrukhw]

Thank you Nana... Actually, I never knew about this change and at first, I got worried, as I only worked with docker...

[ashwinin]

When we watch a video we get so many questions, .how why, and this video answers all those questions the next minute/seconds... Thank you so much. Subscribed!!
