In this episode we take a look at cert-manager.
How to issue TLS certificates automatically and store them in kubernetes secrets.
We break down the process, and how cert manager works.
We also render self signed as well as real Let's Encrypt certificates in Kubernetes.

I know it's big words, but IMO you are creating the best DevOps channel on YT. Thanks for your hard work!
Thank you for the kind words 🙏🏽
You are sir, the reason why I am watching work related videos at holidays. Really interesting, informational and cool edited content. Keep it up!
Well thank you ALOT for this! you dont even know how many hours i was on this subject, now i can have this configuration and make it work in my cluster, many guides just forgets to mention the nginx ingress, thanks for the clear instructions!
Just to clarify, every EVERY videos from Mr.Dempers are clear and intuitive even for both newbie and intermediate k8s users.
I like the way you edit the video, your speech are continuous and delay exactly on time. Your voice are clear, the illustration from images are straightforward.
Step by step guiding are totally insane for such low-level users. It worth every second watching your channel even on holiday.
Thanks to your project. I jumped to K8s Intermediate level really fast.
Thank you for the kind words 🙏🏼
Thank you so much for this tutorial. You have explained all the concepts so well. I already had everything setup and just required the tls to be setup. It is done now.
These videos really are fantastic. They bring so much clarity to an otherwise mystical system...
One of the best tutorial videos I've ever seen. Def subbed. Def going back through your catalog. Might even push a tweet out about it!
Thanks, Marcel.
GM sir, through your guided video I am able to learn kubernetes and how secret it is. Thank you 🙏 for the teachings sir you are DHA 🌳 groot.
And all of a sudden the mist of magic around kubernetes/ingress/docker begins to disappear. Thank you Marcel, please keep going! It's absolutely helpful watching your videos.
Thank you for the step by step how-to Marcel. I was able to install a multi-domain certificate into my kubernete cluster. You are my hero sir.
Struggled with this when i was starting out with k8s. This would be very helpful for beginners.
Thank you so much for all your tutorials, they're incredibly useful, well made and clear
I think this is EXACTLY what I needed to see to learn how to cert my cluster.
Thank you!
I love all the videos I watched from you.
Basically, you make sooo valueable guides! I wish your channel had 1M subs and more views because damn, your content is awesome!
Marcel you are the top one! Your content is always really clear, enjoyable and to the point. At time I get lost with som cli command you use but hey, that makes me a better dev. So once again thank you very much for the effort you put in it. I'm now finally getting into cert management for my cluster on Azure and this was a great deep intro to it.Now I just need to translate it to Terraform lol 😅 A big hug from Italy
You read my mind :). Exactly what I was looking for... Great content and wonderful presentation. Keep it up!
This is what I was looking for complete SSL in k8s and there are dozens of places which give some information but not complete and very well explained. You did a great job. This is awesome. It really helped me. As always Thanks and wish you a very happy new year 🥳
Thanks for the kind words 💪🏽
Happy new year 🎉🍻
I now have my first app properly deployed with k8s, using cert-manager to rotate certificates, in great part thanks to this video!
Thank you for taking the time to create such thoroughly informative videos. It is appreciated more than you know!
Thanks to you, I finnaly combined the results of 10+h of googling and resolve the certificates issuing
the only place I could find my answer! Thanks a lot! Subscribing now
We followed this and it was a breeze thanks to this awesome tutorial! Thanks 🙏🏻
Thank you so much dude. Had to complete a Test assignment for an interview and it helped. :)
Thank you! I was just playing around with this on a kind environment when you dropped your video!
every video of yours I have watched has been so incredibly helpful. thank you.
Amazing video, really clearing up my headache of setting up SSL.
Wow! 😊 Thanks Marcel! Thats the best tutorial out there.
Amazing work, loved the way this was been explained, and thank you.

Thank you. I like the style of explanation.
Works like a charm, thanks!
Thanks! The only issue I ran into is the permission for binding port 80 & 443 on ec2 instance where kind cluster running. I had to assign setcap for kubectl. It works!
You're the beast. Thank you for this.
such an excellent video thanks Marcel :)
your videos are awesome. Thanks so much!
You saved my day. thank you so much 🎉❤
AMAZING CONTENT!!! I will love to see this integrated with Istio
Hey Marcel, the best video explaining this subject. I've done everything working perfectly then stopped work because got expired. Now I'm trying to find out how to renew.
Thanks a lot, that’s a really useful video.
Amazing work, thank you
Hello from Belarus, it was interesting to see wildcard certificates. Thanks =)
Simply brilliant.
amazing work! thank you
Thank you! Well done!
It is kind of way too easy now to be a programer now. Thank you! :)
Do you think you could make a video on how you make your videos? Really love your stuff!
Great video, thanks!
I'm going to try this!
This is too good kind sir 🤲🏾
Maan if all those kubernetes commands you ran worked for me as well as they do for you, I would be 5 years younger :D... thanks for the content, great explanation!
I should have subscribed to this channel earlier. Awesome Content - Just Subscribed !!🔥
Best explanation. Can u also do a tutorial of all things combined? Nginx, load balancing and ssl
Best tutorial!!! Thx
Great Video and Great Explanation. How can we generate the wildcard certificate using cert-manager and aws route53
using dns challenge method.
Good Job dude!
Thank you very much!!!
thanks, do you have a video with eks + aws load balancer as ingress controller as example?
Thanks a lot !!
You have save my bacon once again sir. Thank you.
Thank you for your great tutorial. It was very educational and helped me to learn a lot of topics. However I do have a problem with installing and using cert-manager with the GKE autopilot cluster. The cert manager installs but the webhook doesn't work. Tried with Helm too. Not avail. Is there anything to recommend, please?
a big red hart from Romania ❤
thanks for this video, i have one question, will certmanager will work with NLB in EKS with nginx or kong ingress controller ?
Very nice tutorial thank you. I am wondering if I can use it... How to use the cert-manager when you have an external load balancer? I have a three node rancher cluster with an external nginx load balancer? It's not possible since cert-manager does not expose the secrets right?
Wow awesome tutorial...
thank you !!
Can you do a video on how to install wildcard ssl on ks8
Great! how are certs renewed afterwards?
Very good
For inside cluster communication, can we use cert-manager? any docs available please?
Very nice content, if you have to follow this with aws free tier account, what extra we need to do??
You should create END-TO-END tutorial of setting up HA SSL VAULT with Consul :D
on k8s of course
Sir in my scenario I don't have a loadbalancer and used port forwarding but it only lasts till the terminal is open , after it is closed port forwarding stops.
What I can do for making it permanent other than having a load balancer...???
A.burton-Boston one the better videos , I like and subscribed ... excellent work.
Hi, I tried this in a kubeadm cluster in cloud vms, when i deploy nginx controller, i can access it. but after that when i try to expose a service using a nginx object it returns 302 in a loop
i have multiple applications running in multiple namespaces. Currently i am coping the secret yaml file to all the namespaces. I also have ingress rules in namespace. How to manage the secret file accross the namespace?
if dns01 solver, what are the records needed to create on Cloudflare?
what kind of challenge will be raised by cert-manager and if the challenge fails, then secret wont get created. isnt it.? what are those cases where the challenge will not complete. please explain. Thanks in advance!
Thanks a lot, I got it set up! So this is called TLS termination in Nginx since behind Nginx only port 80 is used?
Yes you're right! TLS is offloaded by default unless passthrough is explicitly stated in the ingress annotation
Is this also going to work in a situation where port 80 and 443 is forwarded to my Synology NAS? my Kubernetes cluster is running on a server. In the past, I spun up an Nginx container to secure my environment with a certificate from let's encrypt, but it never worked because the port was forwarded to my NAS.
Do you have a video about MTLS ?
Wish I had found this tutorial early.
Video Request (If possible): Comparision between K8s, MicroK8s, K3s etc ? What is the difference between docker and containerd, services wise (under the hood)?
amazing stuff, better than the paid ones
