Alternatives to ReplicaSet Deployment (recommended) Deployment is an object which can own ReplicaSets and update them and their Pods via declarative, server-side rolling updates. An ordinary Deployment or ReplicaSet could not implement this workflow. yaml file; We will create a Deployment configuration file that defines the same state as our ReplicaSet example. An important fact to note here is that the way we expose the deployment and the parameters can vary depending. You can define a deployment to create a ReplicaSet or to remove deployments and adopt all their resources with new deployments. The following Deployment definition deploys four pods with nginx as their hosted application:Select the feature compatibility set . The deployment controller extends the ReplicaSet Controller and is responsible for rolling out software updates when you create pods with deployment resources and update them with new versions of your software. I guess Deployments and ReplicaSets will. The deployment process for Deployments is driven by a controller loop, in contrast to DeploymentConfigs which use deployer pods for every new rollout.

Let’s first take a look at how should we create a ReplicaSet. Let's take a brief look at the various options used with the command: webapp: The name of the Deployment--image=nginx: Specifies the name of the container image--replicas=2: Specifies the number of replicas (Pods) to run--dry-run=client: Used to preview the object instead of creating it--output=yaml: Specifies that the output format is. Why Deployment manages multiple ReplicaSets? The answer is Kubernetes wants to support rollback mechanism. A Deployment is another layer above ReplicaSets and Pods, newer and more advanced level concept than ReplicaSets. Let's deploy your front-end application using a deployment object. The Deployment knows that the two Pods can't coexist in the same ReplicaSet, so it creates a second ReplicaSet to hold version 2. The desired replica of the old.
