What is a pod in kubernetes

A Pod is the smallest execution unit in Kubernetes

  • Pods are ephemeral by nature
  • If a pod (or the node it executes on) fails, Kubernetes can automatically create a new replica of that pod to continue operations.

Because we're not supposed to pack multiple processes into a single container, we need a higher-level structure that will allow us to tie and wrap containers together and manage them as a single unit. This is the reasoning behind the pods. Simply put, a Kubernetes pod is a collection of containers.

  • In case of a Node failure, identical Pods are scheduled on other available Nodes in the cluster.

Networking in Kubernetes

Pods that are running inside Kubernetes are running on a private, isolated network. By default they are visible from other pods and services within the same Kubernetes cluster, but not outside that network Every Pod has a unique IP address And it is reachable from all other Pods in the K8s cluster A pod is a host, just like your laptop, having an ip-address and a range of ports that can be alloted to containers A container runs on a specific port inside a pod In a Kubernetes environment, when services are deployed within the same namespace , they can communicate with each other using the service name as the hostname e.g. in the following snippet from appsetting.json form a .net core project, ' document-api'  is the name of the service "DocumentApiConfiguration" : { "BaseUrl" : "http://document-api/" } What if I want to access a service from another namespace? When you want to access a service from another namespace in Kubernetes, you typica...

Terraform

It is an Infrastructure as Code tool Normally, if one has to configure VMs or other resources on the cloud, they have to go to the cloud provider's website and click a lot to get things done as supposed, terraform can do all of that provided you tell it precisely what to do in a .tf file e.g. which cloud provider you are using(GCP, Azure etc), which resource to configure with what specifications. One writes the file in hashicorp language (kinda like JSON) Free and Open source One has to install the CLI terraform init terraform apply  (to make the changes to cloud) terraform destroy

Kubernetes

Some keywords: Node A Node is a worker machine in Kubernetes and may be either a virtual or a physical machine, depending on the cluster Clusters Kubernetes coordinates a highly available cluster of computers (nodes) that are connected to work as a single unit Namespace Namespaces are a way to organize clusters into virtual sub-clusters — they can be helpful when different teams or projects share a Kubernetes cluster . Any number of namespaces are supported within a cluster , each logically separated from others but with the ability to communicate with each other Kubernetes: Kubernetes is a portable, extesible open-source platform for managing and orchestration containerized workloads . It abstracts away complex container management tasks Provides us with declarative configuration to orchestrate containers in different computing environments This orchestration platform gives you the same ease of use and flexibility you might already know from Platform-as-a-Service (PaaS) or Infrastruct...
