海外TECH	DEV Community	Kubernetes CRUD Operation using Go on Docker Desktop	https://dev.to/docker/kubernetes-crud-operation-using-go-on-docker-desktop-3l6a	Kubernetes CRUD Operation using Go on Docker DesktopKubernetes is a popular container orchestration platform used by developers to deploy and manage their applications While Kubernetes provides a powerful command line interface called kubectl for managing Kubernetes resources it can also be accessed programmatically using various programming languages such as Python Go and Java In this blog post we will focus on using Go to perform CRUD Create Read Update and Delete operations on Kubernetes resources Specifically we will demonstrate how to perform CRUD operations on deployments using the Kubernetes API and the official Go client library We will be performing these operations on a local Kubernetes cluster running on Docker Desktop PrerequisitesBefore we start make sure you have the following prerequisites Docker Desktop installedGo installedA basic understanding of Kubernetes concepts such as deployments and pods Setting up the Go environmentTo get started we need to set up our Go environment We will first create a new directory for our project and initialize a new Go module mkdir kubernetes go amp amp cd kubernetes gogo mod init github com lt username gt kubernetes goNext we need to install the ks io client go package which provides a client library for accessing the Kubernetes API go get ks io client go v Creating a deploymentLet s start by creating a deployment using Go In Kubernetes a deployment is used to manage a set of replica pods We will create a deployment that manages a single pod running an Nginx web server First create a new file called create deployment go and add the following code package mainimport fmt os ks io client go kubernetes ks io client go rest ks io client go util retry appsv ks io api apps v func main create a Kubernetes client config err rest InClusterConfig if err nil panic err Error clientset err kubernetes NewForConfig config if err nil panic err Error create the deployment object deployment amp appsv Deployment ObjectMeta metav ObjectMeta Name nginx deployment Spec appsv DeploymentSpec Replicas intPtr Selector amp metav LabelSelector MatchLabels map string string app nginx Template corev PodTemplateSpec ObjectMeta metav ObjectMeta Labels map string string app nginx Spec corev PodSpec Containers corev Container Name nginx Image nginx latest Ports corev ContainerPort ContainerPort create the deployment retryErr retry RetryOnConflict retry DefaultRetry func error err clientset AppsV Deployments default Create deployment return err if retryErr nil fmt Fprintf os Stderr Failed to create deployment v n retryErr os Exit fmt Println Deployment created successfully func intPtr i int int return amp i In this script we first import the necessary packages including ks io client go kubernetes which provides the clientset for accessing the Kubernetes API We also import the appsv package which defines the Deployment resource Next we create a Kubernetes client using the rest InClusterConfig function which returns a rest Config object containing the configuration for accessing the Kubernetes API server We use this config to create a new kubernetes Interface clientset We then create a new Deployment object with the desired specifications including the number of replicas the pod selector and the container specifications The retry RetryOnConflict function is used to ensure that we can safely create the deployment in case of conflicts with existing resources Finally we call the Create function on the Deployments client with the newly created Deployment object to create the deployment on the Kubernetes cluster To run this script simply execute the following command go run create deployment goThis will create a new deployment called nginx deployment with a single replica running the Nginx web server Updating a deploymentNow let s update the deployment we just created We will update the image used by the Nginx container to a newer version Create a new file called update deployment go and add the following code package mainimport fmt os ks io client go kubernetes ks io client go rest ks io client go util retry appsv ks io api apps v func main create a Kubernetes client config err rest InClusterConfig if err nil panic err Error clientset err kubernetes NewForConfig config if err nil panic err Error get the deployment object deployment err clientset AppsV Deployments default Get nginx deployment metav GetOptions if err nil fmt Fprintf os Stderr Failed to get deployment v n err os Exit update the deployment deployment Spec Template Spec Containers Image nginx retryErr retry RetryOnConflict retry DefaultRetry func error updateErr clientset AppsV Deployments default Update deployment return updateErr if retryErr nil fmt Fprintf os Stderr Failed to update deployment v n retryErr os Exit fmt Println Deployment updated successfully In this script we first get the existing deployment object using the Deployments Get function We then update the image used by the Nginx container to version We then use the retry RetryOnConflict function again to ensure that we can safely update the deployment Finally we call the Update function on the Deployments client with the updated Deployment object to update the deployment on the Kubernetes cluster To run this script simply execute the following command go run update deployment goThis will update the existing nginx deployment with the new image Scaling a deploymentNext let s scale the deployment we just updated We will increase the number of replicas from to Create a new file called scale deployment go and add the following code package mainimport fmt os ks io client go kubernetes ks io client go rest ks io client go util retry appsv ks io api apps v func main create a Kubernetes client config err rest InClusterConfig if err nil panic err Error clientset err kubernetes NewForConfig config if err nil panic err Error get the deployment object deployment err clientset AppsV Deployments default Get nginx deployment metav GetOptions if err nil fmt Fprintf os Stderr Failed to get deployment v n err os Exit scale the deployment replicas int deployment Spec Replicas amp replicas retryErr retry RetryOnConflict retry DefaultRetry func error updateErr clientset AppsV Deployments default Update deployment return updateErr if retryErr nil fmt Fprintf os Stderr Failed to scale deployment v n retryErr os Exit fmt Println Deployment scaled successfully In this script we first get the existing deployment object using the Deployments Get function We then set the number of replicas to We then use the retry RetryOnConflict function again to ensure that we can safely update the deployment Finally we call the Update function on the Deployments client with the updated Deployment object to scale the deployment on the Kubernetes cluster To run this script simply execute the following command go run scale deployment goThis will scale the existing nginx deployment to replicas Deleting a deploymentFinally let s delete the deployment we just scaled Create a new file called delete deployment go and add the following code package mainimport fmt os ks io client go kubernetes ks io client go rest metav ks io apimachinery pkg apis meta v func main create a Kubernetes client config err rest InClusterConfig if err nil panic err Error clientset err kubernetes NewForConfig config if err nil panic err Error delete the deployment err clientset AppsV Deployments default Delete nginx deployment amp metav DeleteOptions if err nil fmt Fprintf os Stderr Failed to delete deployment v n err os Exit fmt Println Deployment deleted successfully In this script we simply call the Delete function on the Deployments client with the name of the deployment we want to delete To run this script simply execute the following command go run delete deployment goThis will delete the existing nginx deployment from the Kubernetes cluster ConclusionIn this blog post we have learned how to perform CRUD operations on Kubernetes resources programmatically using Go on Docker Desktop We have covered how to create update retrieve scale and delete a deployment using the Kubernetes API and the client go library in Go Using the Kubernetes API programmatically allows us to automate the management of our Kubernetes resources and integrate them into our applications and workflows This is particularly useful when dealing with large scale Kubernetes clusters and complex deployment scenarios In addition we have demonstrated how to run these scripts on a local Kubernetes cluster using Docker Desktop which allows developers to test their code in a development environment before deploying to a production cluster We hope that this blog post has provided you with a solid foundation for working with the Kubernetes API and client go library in Go and that it will help you automate your Kubernetes workflows and streamline your operations	2023-05-15 05:10:33
