In this video we take a look at Kubernetes Access Control and RBAC.
How traditional kubernetes trusts and authenticates users and the anatomy of a kube config file. We then take a look at roles and rolebindings to give users extended access.

I've learned a lot from your videos. I think we always need to read the official documentation for anything, but sometimes the documentation uses a language format that gets confusing, and you explain it in a way that makes things very clear. Thank you so much.

[@TheArpitkoberoi]

Honestly, one of the most underrated engineering content creators out there. Keep up the good work, keep educating the community 👍

[@robertpolanski6776]

As a rule, I very rarely comment on youtube videos. But here I absolutely have to do it. This video is simply great. Everything is very clearly explained. Thank you!

[@flesz_]

W3 thank you for your efforts of putting a comment , amongst so many comments....

[@dillonhansen71]

He has blessed us with another gift of DevOps knowledge.

[@valentingeorgiev3760]

Simply said, excellent video!

[@martijnvanschie]

Again, another great video. I was struggling with this subject but this is so well explained and with good examples.

[@subhankarpadhy5146]

Hello Marcel, Thanks for posting such quality tutorials. They have been really helpful. Really hoping for many upcoming python tutorials from you. I'm really looking forward to learn and making way for my upcoming DevOps journey

[@jorgerodriguez227]

I absolutely love the way you explain things. Thanks for the great work.

[@joross8]

Great description and background information on RBAC in K8s. Covering off how kubernetes was initially designed for certificate authn/authr, but then adopted oauth over time was great. Hard to find quality info like this elsewhere on the internet.

[@Clobercow1]

Marcel, Your content is golden. You explain this better than anyone I've ever seen! Way to go man! Keep it up!

[@boemowamemmopelwa8894]

The tutorial is amazing!🥳. Thanks

[@maini8888]

You create absolut famos Workshops with fun and great overview with importants point to understand and find a good way in. Personal wish!!!! Many persons will learn devops and kubernetes by self but's not easy without money of an long testing environment on clouds that costs. I know I can use kind and minikube. But then no video tells a great possible way how it is locally from home possible to use a kubernetes with conventional to and from outside like fritzbox dsl... How ingress can be used in home office location with own locally Kind kubernetes. Etc.... I hope we get in future more realy good expert videos from you! You help us all really to go forward. Big thanks

Thanks Marcels ❤

[@user-qm7rs4xg7d]

Note: if you're using an arm64 machine (i.e. Macbook M1 type) and are having issues creating a cluster with image v1.20.2, try any > than v1.20.2 as that image is only built for amd64 and will fail to create the cluster. I am using v1.29.0 and is working fine.

[@ronaldocorrea8007]

excellent. thanks

[@niketsingh87]

this video is better than any documentation. can you please create video explaining OAuth2, JWT tokens, OIDC also ?

[@karthickkarthi.3342]

[@kanakorn]

Thanks, excellent.

[@didomeddach7431]

Thanks for great video i am facing this issue it is saying below after setting use-context as dev and then try to get pods using kubectl get pods, can you please help what is the issue. "The connection to the server 127.0.0.1:52807 was refused - did you specify the right host or port?"

[@akrammohammad8780]

Hello Marcel, very resourceful and informative video. Can you please cover RBAC on HELM 3 as helm 3 doesn't have tiller so how do i give a user permission to only do something like 'helm list' .

[@sauravkalal1037]

Hello Marcel, your video is so amazing and creative really appreciate 👍 Can you please make a video on Grails and Django Nginx docker containerisation please

[@haraldhacker]

Please make a video abouth k8s multi-tenancy for production environments :)

[@ToshuMalhotraiitk]

All I want to know what's the use of alpine container, why it has been created. We could also create csr, certificates for bob on local terminal also, why to create alpine container and mount it locally.

[@HarshaVardhan-mr2bw]

can you please tell me where i can find this ca.crt and ca.key for the rancher cluster

[@user-gc9sp7bx5z]

u just saved my ass.

[@stefanw8203]

Great video

[@JackReacher1]

Marcel why do you do everything from an alpine container?

[@MarcelDempers]

Since there are many OS like windows\mac\linux, many times running command line can be problematic when it comes to portability. Running in a small Alpine container almost guarantees that whatever I run, can be run by you with the most accurate idempotent outcome. Especially when things like awk, grep, etc are added.

[@JackReacher1]

@@MarcelDempers Agreed Can you make videos on Knative and Kubevela?

[@mpattanaik7]

[@shivamgupta5476]

Suggestion Make a video on service account

4.5€/month is a little steep for me (and I'm sure to many others)... you should open a 1€ tier in you Patreon dude...

[@rishabhprajapati8423]

[@sergeibatiuk3468]

It's hard to watch these videos because it's uncomfortable to hold my laptop tilted 45 degrees the whole time

[@kannanswaminathan8210]

if managed cluster (AKS), can we generate oauth token dynamically with validaty of 1 day?

[@garibtube]

Can you please demo this in regards to openID connect

[@spiraldynamics6008]

C'est juste l'effet placebo... Dans le positif comme dans le negatif

[@shan5612]

Please make a video on how to write a Gatekeeper policy ,the policy should be the pods shouldn't be get created if there's no cpu limits and request provided.

[@toragodzen]

Why it looks overcomplicated af... 😕 Great video 🙏

Now that you've got your content and presentation to a 'T', it's time for the blooper reel... Waiting with bated breath...

[@victormendoza3295]

Great video, but way to much. In 2023, 2024 I don't want to be doing this level of work on the infra.
