This whole series covering docker and kubernetes is excellent, precise and easy to understand. Congratulations and thanks for your efforts. You have great teaching abilities. I specifically liked videos that cover practical aspects - for example, application deployment using k8s and docker-compose etc. Keep up your excellent work.

best development /devops youtube channel ever, great content by Nana!

[@krisdoe]

Maybe it is really important to mention that: 1. Know the database (if you are going to deploy database in K8s). Not all works the same way. For example, sharding as concept (found in Elastic) is very important. 2. Know your application requirements. Where is not possible to have stateless application, state-full self-contained application (deployed as StatefulSet) might make sense.

@TechWorld with Nana there is probably a issue in description on 13:38. The service has name "svc1" but the pods dns names have `${pod_name}.svc2` rather `.svc1`

[@Kumbutranjaami]

Can you refer me a trustable source where you have seen pods part of statefulset replicates their STORAGE to next pod in the same statefulset?

[@Clarifier-hv5cl]

She failed to explain the gist of stateful sets by focusing too much on the example. The storage is NOT replicated on its own, but in the case of a distributed MySQL database the slaves communicate with the master to obtain a copy of the data. The storage replication is part of the "application" itself, not the StatefulSet logic. The role of StatefulSets, among other things, is to ensure that pods are created in a particular order (changeable by a policy), help us configure a headless service allowing us to communicate with individual pods by creating DNS entries, and ensuring that each pod can request its own STORAGE by providing a PVC template as part of the StatefulSet. So good call on your part, Kubernetes does NOT take care of storage replication.

[@Kumbutranjaami]

@@Clarifier-hv5cl You are right. Your explonation was so clear. Storage replication has to be handled by application itself.

[@hesse_df3274]

Great video. One point I am messing is about how the service share the request to the pods ?

[@MrChinook1991]

Fantastic video, thank you! What happens in this scenario: a stateful application continually receives requests to update a database (e.g. MySQL) that is hosted on the k8s cluster as a StatefulSet. What happens in the time between Master pod failure and spinning up a new Master pod? Are the update database requests buffered until a new Master pod is available that can write the updates to the DB?

[@syedibrahim-il2gj]

Very Well Explained

[@nikhilrajan2370]

So when do you choose deployments objects with pods and volume claims over state full sets

[@abhi_galav]

the whole video answers your question mate. To put it in simple terms, your front end applications, backend apps, mirco services are perfect candidates for deployment and volumes in deployment on the other hand can be useful to find data like certificates, logs, custom configs, etc..you can however also choose volumes for storing data
