Hey there! I built a learning-by-doing platform for DevOps, SRE, and all other types of infra engineers - https://labs.iximiuz.com. Started working on the project exactly two years ago, and about 12 months ago added a Premium membership, which immediately took off! Still mind-blown by the results, and it's something I build only in my free (from the main job) time. The labs were making ~$3K MRR for a few months before the Black Friday sale and then doubled the annual revenue in a week by making another ~25K at the end of this November.

I'm building a visual Kubernetes Explorer https://github.com/iximiuz/kexp. Because learning Linux & Containers can be fun.

I wrote this a while ago https://iximiuz.com/en/posts/computer-networking-101. You may find it useful.

Hey thanks a lot for sharing it. But what I need is to know about TCP, UDP, HTTP, TLS/SSL, HTTP 1.1, Reverse Proxy, Forward Proxy, etc... So if you have some resources for that also please share it. I would be grateful to you.

Thanks for sharing! :)

Containers for sure aren't a replacement for VMs. And indeed, VMs still have and will have legitimate use cases. There is actually a relatively simple way to turn a container into a VM. Maybe you'll find it useful https://iximiuz.com/en/posts/from-docker-container-to-bootab...

It does work! Actually, it's my favorite type of containers so far https://iximiuz.com/en/posts/not-every-container-has-an-oper...

I still have a hope that increasing awareness of the problem may eventually lead to a reduction in the number of Dockerfiles starting `FROM <something_huge_and_not_really_needed>`.

They are 100% hand-drawn

thanks for pointing me to how you making these diagrams, very nice posts, keep up this good work.

Thanks a bunch!

Thank you very much for your feedback! I appreciate it a lot because at the end of the day that's what keeps me motivated!

The ip tool chain is a worthy thing to promote.

I especially like all of the replace verbs, which I wish I’d known about sooner. They make idempotency much simpler to express without any if ! ip thing get <long list of route args>; then ip add <same list of args> ; fi stuff.

That's cool! Here's a synopsis of `ip replace`: "replace will either modify an existing address or create a new one if the specified address does not exist"

Well, to be honest, some level of sarcasm was meant to be in this title because it precedes a 4000+ words explanation of the topic... But seems like I'm pretty bad at writing good titles. For sure I didn't mean to make anyone feel bad.

FWIW, I thought it was obviously either stupidity[0] or sarcasm based on the title, and the 4000+ words explanation confirmed it as the latter. Can't speak for anyone else, though.

Edit: 0: well, or lies / container vendor shilling

Appreciate the response. Thank you.
