海外TECH	DEV Community	Getting Started with Kubernetes as a Developer	https://dev.to/okteto/getting-started-with-kubernetes-as-a-developer-2jea	Getting Started with Kubernetes as a DeveloperAre you tired of listening to everyone in DevOps talk about “Kubernetes while you re still struggling with how to pronounce it Unless you started programming today I m pretty sure you have heard the word but most likely as a developer you haven t gotten the chance to learn about it maybe because it seems intimidating or maybe because you aren t sure how it s useful for you Let me take you on a journey from being a developer clueless about Kubernetes to one who can understand all the mumbo jumbo the infra team talks about In the process you ll also start appreciating its beauty and usefulness in increasing developer productivity We ve got a lot to cover over the course of this series so let s jump right in The Death Of “It Works On My Machine It s important to have an understanding of containers before talking about Kubernetes Containers are executable packages of software that contain all the code and dependencies necessary to run an application anywhere And by anywhere I literally mean anywhere my laptop your laptop or even on “the cloud Are containers starting to sound similar to virtual machines Well they re not and in fact they re even better Why Because unlike VMs containers do not contain operating system images This means they re much more lightweight To create and run containers locally you would use a container engine like Docker Containers grew in popularity because they truly embraced the ideology of write once run anywhere Because of how fast and easy it is to deploy containers they increased developer productivity significantly A fun fact is that Okteto also utilizes these containers to give you a live preview of the changes you make while developing locally But as more and more companies started using containers a new problem arose How do you manage thousands of containers running on distributed systems And that s where Kubernetes saved the day Kubernetes To The Rescue Kubernetes often abbreviated as Ks is a container orchestration platform Let me explain this in very simple terms Let s say you have your app which you have containerized So you run a bunch of containers to serve your app to users But how do you manage these different containers The situation is complicated even more by the fact that these containers needn t necessarily be running on the same machine This is where Ks comes to the rescue It makes deploying managing and scaling containerized workloads a breeze I want to explicitly call out here that Ks is NOT a container engine like Docker Rather it is a container orchestrator As a developer you won t need to worry about “how Ks does all this orchestration You probably also will not have to set up a Ks cluster for your application But what you would mostly be doing is interacting with a cluster set up for you by the infrastructure team So it becomes important to be familiar with the Ks objects you ll be interacting with That s what we ll be focusing on in the articles in this series Before we do that let s have a high level idea about the architecture of Kubernetes so that you re not totally clueless about what is happening under the hood Kubernetes Under The HoodIn the Kubernetes world a machine is called a node A Ks “cluster is nothing but a group of nodes that run your containerized application These nodes may be bare metal servers in your home or instances you re running on a cloud provider These nodes are also of two types worker and master The worker nodes are the ones where your application s containers would actually be running Kubernetes actually uses an object called Pod to run these containers but more on that in the next article Three essential things running on a worker node in a Kubernetes cluster are Container runtime This should be no surprise since a container runtime is what is actually responsible for running containers Kubernetes supports multiple container runtimes including Docker and containerd kubelet This is the agent which is responsible for communicating with the Kubernetes control plane running on the master node It is responsible for executing any instructions it receives from the control plane It also makes sure that containers are running in the pods properly kube proxy This is a network proxy running on each node Not going into much detail you can think of it as being responsible for network communications within the cluster as well as outside the cluster We ll be exploring how all these communications happen between pods in a future article The master node is the one which has all the components of the Kubernetes control plane running on it You can also set up multiple master nodes for high availability Following are some important control plane components you should be familiar with kube apiserver This exposes the Kubernetes API which we can use to talk to our Ks cluster This can be thought of as the frontend for the Kubernetes control plane etcd This is the distributed key value store where all cluster related data is stored For security reasons it is only accessible through the API server This also helps ensure that the data stored in etcd is consistent kube scheduler This is responsible for scheduling pods on available worker nodes While scheduling it takes into consideration resource requirements of the pod and any other constraints that we specify kube controller manager A controller in Ks is responsible for observing an object and making sure that the current state of that object matches the desired state that we specified There are various controllers in Ks for different objects All these are combined into a single binary which is the kube controller manager cloud controller manager This is the component which lets you link your cluster to a cloud provider This binary contains all the cloud provider specific controllers So when something like a node termination happens in the cloud provider then this component will be responsible for handling that ConclusionAnd this covers all the basics of the Kubernetes architecture The really cool thing is that while it s good to have this knowledge as a Developer you probably won t have to worry about any of this at all especially if your team is using development environments like those provided by Okteto When you use Okteto you re able to develop from the comfort of your favorite IDE while at the same time you re able to see changes you make to your app live without having to commit build push or deploy You get to see a deployed preview of your changes exactly as users would see in production since Okteto deploys on an actual Kubernetes cluster In the next article we ll start diving deeper into common Kubernetes objects We will explore the Pods I mentioned briefly here and see how they can be managed using a Deployment which is another important Kubernetes object So while you wait for the next article in the series why don t you go give Okteto a try and see the magic for yourself The Kubernetes for Developers blog series has now concluded and you can find all the posts in this series here	2022-01-27 15:45:00
