I don't get it, I think that k8s is the best software written since win95. It redefines computing in the same way IMHO. I have some experience in working with k8s on prod and I loved every moment of it. I'm definitely missing something.

Took a while to find this. K8s is great, IMO most of the people with alternative setups are just rebuilding (usually worse) or compressing (specific to their use case) k8s features that have been GA for a long time.

Spend some time learning it, using it to deploy simple apps, and you won't go back to deploying in a VM again imo.

This only gets better with ai-assisted development, any model is going to produce much better results for k8s given the huge training set vs someone's bespoke build rube-goldberg machine.

I deploy prod by running a shell script I wrote that rsyncs the latest version of the codebase to my server, then sshs into the server and restarts the relevant services

how could k8s improve my deployment process?

You know your app better than me, but here are some practical reasons for the typical B2C app:

split deployments -- perhaps you want to see how an update impacts something: if error rates change, if conversion rates change, w/e. K8s makes this pretty easy to do via something like a canary or blue green deployment. Likewise, if you need to rollback, you can do this easily as well from a known good image.

Perhaps you need multiple servers -- not for scale -- but to be closer to your users geographically. 1 server in each of -5-10 AZs makes the updates a bit more complicated, especially if you need to do something like a db schema update.

Perhaps your traffic is lumpy and peaks during specific times of the year. Instead of provisioning a bigger VM during these times, your would prefer to scale horizontally automatically. Likewise, depending on the predictable-ness of the distribution of traffic, running a larger machine all the time might be very expensive for only the occasional burst of traffic.

To be very clear, you can do all of this without k8s. The question is, is it easier to do it with or without? IMO, it is a personal decision, and k8s makes a lot of sense to me. If it doesn't make a ton of sense for your app, don't use it.

What happens when your new version is broken? Kubernetes would rollback to old version. You have to rerun the deployment script and hope you have the old version available. Kubernetes will even deploy new version to some copies, test it, and then roll out the whole thing when it works.

Also, Kubernetes uses immutable images and containers so you don't have to worry about dependencies or partial deploys.

I think it's just that k8s allows you to shoot yourself in the foot, thus it gets all the blame.

when in reality, you can go very bare-bones with k8s, but people pretend like only the most extreme complexity is what's possible because it's not easy to admit that k8s is actually quite practical in a lot of ways, especially for avoiding drift and automation

that's my take on it

[RyanHamilton]

Can you expand how it redefined computing for you personally?

[dionian]

I noticed in his article he said something like 'and then devops team puts a ton of complexity...' which doesnt seem like a k8s problem.

> the best software written since win95

This feels like what us Brits would call "damning with faint praise".

Windows 95 was terrible. Really bad. If you really mean to say that Kubernetes is revolutionary and well-engineered, Windows 2000 would be a much better example.

[dilyevsky]

it sold like 7 mil copies in a month. yes 98 was much more polished overall but 95 revolutionized personal computing as it was much more accessible than NeXT stuff

[linuxftw]

You're not missing anything. There's legions of amateurs that dislike k8s because they don't understand the value.

[c0rruptbytes]

it's always a skill issue when it comes to people complaining with k8s

knowing when and when not to use k8s, is also a skill
