When I was asked to deploy containers to Kubernetes at a new job, I was confident I could learn it quickly.
Well, I was wrong.
Kubernetes is complex, mainly because there are underlying skills that developers do not possess which makes it confusing.
So it's vital to first learn these concepts, and only then Kubernetes will make sense.
In this video, I'll teach you what those 5 concepts are.

If you do those first kubernetes will be a lot more familiar to you.

  • Hi Good One, But I think for some one to even understand containers, they should not go use docket first, with out docker they should try to containerize a process in their linux using cgroups and namespaces linux kernel concepts which is infac he fundamental concept behind containers and then kubernetes is just a orchestration and management of these containers.. with some intelligence for load placing etc... across nodes... or machines ( physical.. or virtuall.. )

  • Hi Travis. Thankyou for the Video. Even though, I understand the Docker / Kube basics, how would you relate this with Serverless Architecture using Lambda Functions? I started to learn SAM but cannot able differentiate in terms of which one Supersedes when creating server or deploying Apps? Any general guidelines would be helpful. Thankyou.

    @faisalraj6654@faisalraj66545 ай бұрын

    • IMO, Lamdas/Serverless Architecture are a completely different ways to create solutions. A Lambda is an ephemeral process that does not reside on a server, nor in a container. It is a complete, standalone stateless application; the only way to have data persistence is to have the Lambda send whatever data to an external store. If you need to orchestrate Lambdas, Step Functions are what is usually used. Containers, on the other hand, can persist as long as you want, and can be more heavy-weight. Since containers can scale up and down, external stores can be mounted for data persistence.

  • @Travis I believe there is a mistake in your explanation with regards to Docker @3:20. When one creates a container out of the image, all the necessary dependencies/libraries are already baked into the image, there is no re-running of those instructions when a container is started. If everything runs again and needs to install the libs/dependencies, there is no point of creating the image. One can just use a shell script file as a start up script.

  • I've been working with k8s as a hobby for over 2 years now. I was looking for (and still working on) a way to run a platform I'd like to commercialize at some point. And, although I have a successfully running k8s cluster with like 30+ apps running, and I'm heading to my own very opinionated platform. I still wouldn't ever call myself an expert. I'm a jack of all trades and master of none. These basics are definitely important, but there is a whole lot more.

    @scottamolinari@scottamolinari2 ай бұрын

    • That being said, I think a general understanding of what k8s means in terms of not only being an orchestration management system for containerized apps is important, but also understanding the fluidity between development, devOps and turning k8s into a PaaS for your company, is hugely important too. You could theoretically have all development outside of k8s, however, I know this is missing out on taking full advantage of k8s. And, having all dev'ing done outside of k8s is going to be a constant source of uncertainty, when things go wrong. Is the root cause the dev environment or is it the k8s environment? Yes, containers are supposed to help alleviate this concern, but they don't really in the end. The only way to remove that big question is to have the code being developed actually running in a real cluster with all the accessible services too. Once you see this path and can offer it to devs in an automated way, you also increase development velocity manyfold. It's why SRE is being renamed platform engineer slowly but surely. And yeah again, I'm just doing this as a hobby. But, I love it. 😁

  • Dude, YAML is not a superset of JSON. JSON uses lots of double quotes - for all keys and many values. And ignores whitespace. YAML depends on whitespace (which can be really annoying sometimes, especially if people throw in tabs) and typically doesn't use quotes ... though you can, but you need to be careful. And it auto-interprets and changes some of your values '(like 'NO" being changed to 'false', even if you wanted 'NO" to refer to Norway. or '1.0' is changed to '1' so be careful with version numbers). JSON doesn't do this nonsense.

Should you alias kubectl as `k`, you now need to manually edit your example every time you want to share a command in a document, over chat, or when creating a bug report. Alias flags you want to (nearly) always pass. Only shorten commands if you know you won't be sharing examples very often. I alias `n` to nano for example.

So this is the quote: "After a few months of us working together, I pointed out that YAML (which most definitely stood for Yet Another Markup Language at that time) was not really a markup language (marking up various elements of a text document) but a serialization language (textual representation of typed/cyclical data graphs). We all liked the name YAML, so we backronymed it to mean YAML Ain't Markup Language." I guess the "marketing" for their name update hadn't penetrated the circles I'm in, since I've only ever heard to original naming for many years. But, good to know what it is officially.
