Please continue this. Also focus for production grade setups

Bro where is the next video. You content is gold! I'd love if you add the next video about how to setup the replica. Thx!

[intsanerarity]

you are a legend, will there be the last part of this video series?

Hey Marcel, Thanks :) just thanks. I didn't go that route, but your series on k8s has been instrumental in my career direction ! now wih kuber abilities !! TY sir !

[mroshan]

Hi Marcel, good to see you back. Always loved your delivery ❤

[Fullflexno]

Hey, big guy, Marcel! Thanks for providing so much quality content, pleas hurry up and give us more 🥺❤

Thank you for this interesting and insightful series of videos on setting up a PostgreSQL cluster. 
When can we expect the next video? I need the following !
I'm currently in the process of deploying my own PostgreSQL cluster on AKS. It would be great and helpful to have and see a demonstration of how to configure replication on Kubernetes and automate the primary promotion to the replica in case of failover (along with guidance on configuring for production environments).
Excellent work :)
I'm looking forward to the next video, which I hope will arrive very soon.

[azrafal]

Sir please make some videos on Cassandra. Learned a lot from your videos. Thank you very much.

[lior]

love your videos, you are a true professional and a grate tutor.
waiting for your next video on the topic.

[tiagomedeiros]

Thank you. I would like to suggest a future video about karpenter

[dillonhansen]

I love that you keep saying "You will lose data". People need to hear that.

[tayyab_fayyaz]

Great explanation sir, it would be helpful if your similar tutorial PG bouncer with a same of different namespace.

[captain-daybyday]

Nice one @MarcelDempers, Did you post second part to cover replication ?

[pigrebanto]

thanks and well done! Is the next video yet to come?

[JuanNicolas]

hey Marcel, thanks for these videos, they helped me a lot. Is there any update on the replication 2nd part of this? I Tried to figure out how to create the secondary pods as replication server but, I'm still stuck on the configmap and if I need to use a second statefulset yaml file for that to provide new configmap configurations.

[MrGenbu]

can you please make one for mongodb replicaset its very frustrating

Hello Marcel,



I am one of the subscribers to your channel. Your videos are quite informative and very helpful in understanding the technology. -:)

I have couple of doubts related to tools that are used. Could you please help clarify these doubts please?

In REAL WORLD projects, tools such as Jenkins, ELK stack, Databases, RabbitMQ/ActiveMQ, Kafka etc. are generally provisioned on EC2s (or) Vendor provided/managed cloud environments (SaaS) (or) Cloud Provider(AWS/Azure etc.) specific provided/managed environments but not on Kubernetes/EKS?

And,

Only microservices are deployed on K8s clusters and they connect to these tools via K8s environment configurations?

It is very confusing and struggling to understand as most of the tutorials/examples in Internet are showcasing above mentioned tools to provision on K8s along with microservices.

Kindly help clarifying the doubt!

Thank you.. :-)

Thank you for this. If you have a replica of a pod, and the main one dies, then the replica dies, are you out of luck and the data is lost? Or are replicas constantly created?

[IIGrudge]

You most likely won't be doing this in the real world as handling stateful workload robustly is quite a challenge on K8s. Better to use an operator like Zalando to handle things like HA, backups, upgrades.

if i have 3 replicas StatfulSet, is the data automatically replicated into the 3 pods' volumes if i created the data through a client pod connecting to the headless postgres svc
