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.

Thanks , :)
thanks
Thanks dude
hero
Better than 13min ad I just watched.
One of the best decisions I made lately: subbed to this man's channel. I love the practical approach he takes in sharing the knowledge.
you are quickly being my favourite tech tuber , you make great content travis
perfect timing! I was just looking for this. Keep up the great work!
Thank you for this video, I was looking into learning kubernetes. I like your videos you deserve more subs man :D
Travis, watching your videos gives me good motivation. I also started learning new stuff!! thanks 👍
I’m Kubernetes certified CKA & CKAD
I’m fully agree with you about the prerequisites and also something really important to emphasize is mastering Linux before going to K8s because this is the only OS Kubernetes deals with
100%. Are you for that CKS now?!?! I've been putting off the CKA now for like 4 years, myself. 😆
@@TravisMedia I surely will 😊
I am studying an intro to containers and I would lije to know in your opinión it is worth certification in containers. Are there many jobs oportunities? Thanks for your answer.
GIGA CKAD
Have you been able to get a job because of your cka or ckad?
Travis, u inspired me 5 months back to go on Devops journey.
I am using udemy to prepae for Devops job.
I completd :
1.Linux Administrator course : Imran Afzal
2.Bash scripting----> Narendra
3.Git --> Bogdan stashuk
4.Maven --> Bharath Thippireddy
As of now, trying to complete AWS [Fundamentals + Solutions Architect Associate] by stephen .
Next will b : SonarQube---->Nexus---->Docker--->Kubernetes--->Terraform--->Ansible---->Prometheus & Graffana---->Python
Bro any chance of getting job for you with current knowledge? my issue is I will learn for 4-5 months then i gave up and i have to start all again. I lost hope too.
I think we have to learn a lot to get into DevOps junior roles too
@@goutham9831 wat tools have u completed till now ?
@@goutham9831😮
@@goutham9831 prepare ur own notes. Keep revising it I am about to finish Stephen mareck solution architect associate. Docker kubernetes terraform Ansible r left now. 4 months.
Amazing info video, completely agree to you Travis. Thanks a lot.
You teach from fundamental and I loved it. It gave me a blueprint abt how to understand something in this case kubernetes in the big picture
Thank you so much for the video, it was very helpful!! I'm so happy that I found your channel, your content is amazing!! Keep it up 💗⭐
Thanks for all you do! 💪🏽
Outstanding. Thanks for keeping it short and to the point.
Thanks man. Awesome video. Keep it up!
Great information
Thank you for this video for us learning kubernetes
Thank you for sharing this to learn Kubernatares ❤
Docker is a huge prerequisite as well as docker compose and swarm to get you used to microarchitecture, how networks function and communicate as well as services in between containers, and swarm to get you used to orchestration. If you do those first kubernetes will be a lot more familiar to you.
Thank you, i'm a network engineer taking on the devop role at our company. At the moment I am struggling to deploy apps on a eks cluster. I will be checking out the udemy course you recommended.
Hi, I am on that course right now, amazing option, from my point of view the best one I've ever seen about Kubernetes Administration.
Thank you for this video i wanted to learn all these concept and your video gave me a starting point for that.
Perfect timing. Thank you.
Came at the right time. Thank you
Holy Smokes... I didn't know it was this involved... I'm halfway home in terms of the requirements, but the stuff about networking will absolutely need to be learned....
Thank you very much, this was arranged in a verly clear and correct way.
Can you make a video about how to debug ongoing and occouring issues with Pods, and how to monitor k8s?
Thank you, this is really helpful
I used to be a PHP developer 20 years ago. I had no idea I'd be interested in this stuff but I seem to be. It's like lego but cooler. Your videos are very clear, concise, and most of all.... WELL PACED! nice one my man.
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.
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 always has helpful tips..Let's Gooooooooo
Hey nice one ! Any prompts on how to go about getting a legacy app containerized..
Great video, thank you!
Great vid Travis! In the same boat as you were haha, need to deploy containers in kubernetes for work😂
tank you for the course tips
Brilliant video! Thanks!
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.. )
I would include learning Docker Compose as the second step. It's a highly effective method for running containers locally, regardless of whether they're configured to run in a Kubernetes cluster or other environments.
Hi Travis. Amazing content. I wanted to inquire on your video setup. Would you be willing to answer a few questions?
Where I work, we abandoned docker and started using Podman about a year ago.
Why?
That's basically the same thing I guess.. It has a lot of enhancements though and the best thing is it automatically starts up when you start the the laptop/computer. No more systemctl start docker 🥲
Only principal software engineer knows, probably.
podman is essentially same as docker but has rootless advantage and will most likely be the replacement for docker
@@SweetMelon-sd1qu you nailed it, it is more secure than docker
Great video, YAML stands for "Yet Another Markup Language"
Thank you ❤
Hi there.
i am now a CCNA, RHCSA, RHCE and i have knowledge in WinServ
Do you recommend me going through AWS then some basic Docker and then to CKA?
thanks, helpful
great video but I thought it was going to be learning about "Kubnernetes" not Kubernetes... you fooled me :)
seriously though, truly great and appreciated video. Thanks.
I didn’t understand anything but the feeling they were pleasant🤩
Thank you.
google has a paper on Borg that is a good reading to understand some of the design decisions behind kubernetes
can you share the link please?
Thank you
I learnt kube from a developer perspective in around 6 months, plus additional 1 months for Jenkins and additional CI/CD stuff. I am now learning something like ansible and planning for AWS. 😅
congrats! you are on 1/20 step to understand how everything works
@@ordinaryggso true 😂 IT hole is real
nice for beginner
@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.
thank you
If you have less then 100 servers and < 1000 containers don't even bother go into k8s. Most of orgs even some medium-big businesses don't need such complexity to maintain their MONOLITH-microservice architecture)
Same situation here. Familiarity with Helm is also needed.
Yes!
How about hinglish in the course ?
BRAVO!
great info
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.
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. 😁
Ctl as control feels a lot more natural to me. Ctl as cuttle seems like raised-by-wolves speak.
What makes AWS EKS a “managed service?”
I think you just saved me from a decent year of walking in hell. Thank you Travis, great content!
I'm a software engineer and I have a question: why are companies starting to demand Devops skills from software engineers?
Woww. Thanks
Prerequisites Linux an docker ..
I don't think any other thing needed..
Travis media?
I was tought that was other channel.
Clear English on the course and is 84% off for the next 10 hours, wish me luck
If only u could do a video where u explain everything with real situations, like say in order for CZcams to run we need kubernetes as the middle man
I'm absorbed in this content. I had the privilege of reading something similar, and I was absorbed. "Mastering AWS: A Software Engineers Guide" by Nathan Vale
Content begins at 2:10. You are welcome.
YAML aint a superset of JSON ;-)
Self delete isn't the best option. Policies that crush one party but prop up the other party will always test the sanity of the one being crushed. Can't delete policy.
Can listen to this, but its hard to watch with so many edits every few seconds. Otherwise solid content on basics of Kubernetes and getting started.
You haven't mentioned the helm package manager, and where companies will force you to write 100 services for an app if there is no helm for the given target image, and you have to do it in a day :D.
"Yaml which stands for 'Yaml ain't a Markup Language' "
👍
Great video!! But ummmm actuallyyyy.... YAML stands for Yet Another Markup Language, not YAML Ain't Markup Language. Super important difference
"Depending on whom you ask, YAML stands for yet another markup language or YAML ain’t markup language (a recursive acronym), which emphasizes that YAML is for data, not documents." - Red Hat
@@caitlinmclaren2695 I stand corrected. Thank you for the info!
type kubectl like it's your first name. Don't alias it. Grow your muscle memory.
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.
10:41 I very much disagree. Use the actual command as doing so makes copying examples painless. 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.
2:10
Typo? "Kubnernetes" => "Kubernetes"
Thank you 🙏🏻. Fixed 🤦♂️
Travis, this content is SO helpful, but damn, you talk wayyyyyyyyyy too fast (I had to play it at 75%) and this video would be significantly easier to follow if it had some text overlays. My poor little visual learning brain struggled with this one.
It's "Yet Another Markup Language", not "Yaml Ain't Markup Language"
stackoverflow.com/questions/6968366/if-yaml-aint-markup-language-what-is-it
@@TravisMediaThanks for sharing. 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.
@@MuaahaaEither way, I think its a hotly debated thing. I just ran with what popped in my head for the video. Thanks for bringing it up though. Good to know more about it now.
You cant say stuff like "spot instance automation with fallback" in the same video you are recommending people to study basic cloud tech
Africa?
never use KGF
I'm almost positive that YAML stood for "Yet Another Markup Language"
“Developers have a weakness when it comes to networking”
_I’m in this photo and I do not like it_
managing a kube cluster sounds like the most boring job ever, akin to guarding sheep.
Please convince me otherwise as I m trying to find motivation to learn this so as to shamelessly ride this hype wave.
This is called dev ops, and yes, many find it boring, as mostly about managing and monitoring configuration.
But it is massively rewarding to get something running smoothly and reliably.
You didn't actually list a *single* concept specific to kubernetes. This is a list of things you need to know for docker-compose
What? You can use Kubernetes without knowing what containerization is?
Please clap
The certified Kubernetes installers dont add up for Africa
KGB, haha
YAML = "Yet Another Markup Language"
Bloated caution for bloated tech from bloated tech youtuber. Thank god I can quickly list "concepts" in comments.
Your voice sounds like a rapper.
almost half of the video is wording that has nothing to do with the title, and he brings a sponsor in the middle!!!! this guy is a scam
Do NOT Learn Kubernetes.... Ok I will take your advice
