Your teaching skills has no match .. Thank U for providing it for free. Grateful. 🎉 What you are providing is saving time and brain damage in understanding other videos related k8s. Thank you for all those efforts.

Pod has running specification and can have multiple container. Side car container for service mesh. Service mesh is established by sidecar proxy. Deployment is capable of providing capabilities like autohealing and autoscaling. Deployment will create an intermediate resource called replicaset and then replicaset will create/rollout pod replicas.. So end of the day we are creating pods. Since replicaset is Kubernetes controller , it will implement autohealing and ensure that there are always two replicas of pods running. A Controller ensure desired state matches the current state in Kubernetes.

Don't have words. There are lots of peoples out there won't teach anything to anyone. Meanwhile like you sir absolutely gods gifted kid who is helping lakhs of peoples and soon in Crs. Got 2 offers finally. From Cloud engineer to DevOps Finally. Thanks again sir

This is for people who don't understand "Replica Set": -> In k8s, there is a concept called controllers (we saw this in architecture video). The main work of controller is to watching the POD is running in desired state or not. -> If not it sends the message to scheduler to create a new resource to achieve the desired state. -> One of the controller is called "Deployment". -> "Deployment" first creates "replica set(actual controller)" managed by "deployment" and replica set creates and manages the POD. -> Still confusing see the bellow picture: +-----------------------------+ | Deployment | | (desired state: 3) | +-----------------------------+ | | creates or updates | +----------------------------+ | ReplicaSet | | (desired state: 3) | +----------------------------+ | | creates or updates | +----------------------+ | Pod | (POD -> execution environment for the containers) +----------------------+ | | runs the containers | +----------------------+ | Container | +----------------------+

The similarity there is that you can pass in all the arguments in the yaml file rather than on the command line. Docker -compose helps in building re-usable scripts for running containers.
