The standard replica set deployment for a production system is a three-member replica set. While ReplicaSets can be used independently, today they're mainly used by Deployments as a mechanism. When you updated the Deployment, it created a new ReplicaSet (nginx-deployment-1564180365) and scaled it up to 1 and waited for it to come up. In summary, Controller reads the Deployment spec, forwards the pod configuration to ReplicaSet and then it creates the pods with. Replication in MongoDB. Deployment Patterns for MongoDB Replica Set. But what is the best for this case ? This Pod is stateful (I am using volume hostPath to keep the data) and is deployed using nodeSelector to keep it always on the same Node. This naming is consistent, so you can make sure you always have. You will almost always use only Deployment for deploying an application, and for every change, e. That’s the job of the ReplicaSet object. Rolling Deployment. If a user-facing Pod fails or becomes overworked, the Deployment allocates work to a Pod from the ReplicaSet to maintain responsiveness. Tuy nhiên, Deployment Controller, 1 khái niệm ở mức cao hơn sẽ quản lý các ReplicaSet và cung cấp các cập nhật cho pod kèm theo các tính năng hữu ích khác. The Deployment will create a replica set before creating the Pod. you can list all the pods in custom-namespace. That method will check the Deployment status and perform the. Typically license costs constitute to be about 40% and so with license-free standby replica the secondary will be about 40% less expensive. It creates a replica of 4 busybox pods. Deployment provides you the capabilities to upgrade your applications smoothly using rolling updates, undo changes, pause, and resume changes as required. Below is a simple example of a rolling update and undo operation (rollback) is explained. The deployment sets up a ReplicaSet with three pod replicas, specified in the replicasfield under spec. . replicas field. Provide a URL for accessing the API. El Deployment está reduciendo su(s) ReplicaSet(s) más antiguo(s). It will create Deployment object in imperative way. A deployment creates a ReplicaSet that has the purpose of maintaining a "set" of "replicas" of said deployment. Like deployment. A ReplicaSet is a Kubernetes object that ensures that a specified number of replicas of a pod are running at any given time. kubernetes deployment 컨트롤러는 지속적으로 배포된 인스턴스들을. Use this procedure to deploy a new replica set that Ops Manager. The original node affinity specified at the . The Deployment is scaling down its older ReplicaSet(s). It uses a template to describe what each Pod must contain. You will almost never create this directly. » Prerequisites. A running kubernetes cluster stores a lot of interrelated resources, such as deployment, replicaset and pod, which are a set of related resources that we commonly use. e: class-name and the pod created will be class-name-0 and you can replace the _ by -. ReplicaSet. This deployment of DCs is known as a replica set. As mentioned in the previous section, there are two ways to define or configure a ReplicaSet; directly through a YAML configuration file or through a deployment. Repare que ao aplicar o deployment ele ja cria automaticamente o ReplicaSet e por consequência o pod, como não especifiquei o número de réplicas ele criou apenas um pod. A ReplicaSet, as the name implies, is a set of replicas (Pods) maintained with their Revision history. Kubernetes Documentation. In the simplest case, a deployment just creates a new replication. »A replica set is a group of MongoDB deployments that maintain the same data set. spec. Also, the template used to create the Pods will be specified in the Deployment YAML file. In general, you can set up replica sets for testing either with RBAC enabled or disabled. ReplicaSet is the next-generation ReplicationController that. Changes to label selectors make existing pods fall out of ReplicaSet's scope, so if you change labels and label selector the pods are no longer "controlled" by ReplicaSet. " In order to keep. I have a command to scale all the deployments to zero. Deployment menaikkan kapasitas ReplicaSet terbaru. The configuration of each Deployment revision is stored in its ReplicaSets; therefore, once an old ReplicaSet is deleted, you lose the ability to rollback to that revision of Deployment. Walaupun ReplicaSet dapat digunakan secara independen, seringkali ReplicaSet digunakan oleh Deployments sebagai mekanisme untuk mengorkestrasi pembuatan,. The following is an example ReplicaSet definition: apiVersion: apps/v1 kind:. Does any one have implemented blue green deployment while cleaning the old stuff?The solution(s) : Use a StatefulSet, ReplicaSet or DaemonSet to ensure the Pod creation after a Node failure. When a new version of an application is deployed, the Deployment creates a new ReplicaSet with. 1. Declarative way, edit this line in your Yaml file: replicas: 2. The Deployment and DeploymentConfig API objects in OpenShift Container Platform provide two similar but different methods for fine-grained management over common user applications. e. Deployment is recommended for application services. Deployment is the easiest and most used resource for deploying your application. In kubernetes where pods are controlled by the replicaSet, if you kill a pod it will again be recreated. Get the replicaset list for the Deployment we just created. When you updated the Deployment, it created a new ReplicaSet (nginx-deployment-1564180365) and scaled it up to 1 and waited for it to come up. ReplicaSet は Pod を作成して管理するが、 ReplicaSet が Pod を所有しているわけではない. StatefulSet is the workload API object used to manage stateful applications. In this case, you select a label that is defined in the Pod template (app: nginx). spec. This Replicaset is responsible for creating Pod's. 1 Answer. 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. We can also roll out an app via a ReplicaSet but a deployment resource give us a declarative application update. Replication Controllers perform the same function as ReplicaSets, but Replication Controllers are old school. Agora, vamos mudar a. 2. In other words, a Deployment makes sure that a pod or homogeneous set of pods are always up and available. Here you see that when you first created the Deployment, it created a ReplicaSet (nginx-deployment-2035384211) and scaled it up to 3 replicas directly. Here is the manifest file which will make sure that the deployment of your web application has 3 replicasets always up and running. This Deployment specifies that it wants to maintain 3 replicas of a Pod running the Nginx container. The ReplicaSet is responsible for making sure that the number of replicas specified are always running. Imperative way: (this will then diverge from what you have in your yaml-file) kubectl scale deployment mage-di --replicas=2. Share. To delete all 3 objects (Pod, ReplicaSet and Deployment), please execute the following command. A deployment refers to a Kubernetes object that manages the performance and specifies the desired behavior of a pod. If you deployed Windows resources, then all instances of linux in the following output are windows. Default value: pod. kubernetes. Declarative way, edit this line in your Yaml file: replicas: 2. replicas property from the YAML file. It ensures zero downtime by incrementally updating pod instances with new ones. yml deployment. From the above, it should be clear that there is a Deployment with a single ReplicaSet that contains a single Pod running the busybox image. OpenShift Container Platform adds expanded support for the software development and deployment lifecycle with the concept of deployments. A standalone instance isn't a good choice for a production deployment because it can be a single point of failure. Select the MongoDB version for your replica set. If a node is added/removed from a cluster, DaemonSet automatically adds/deletes the pod. 8 user guide shows how to create a deployment in. When the update starts, the old ReplicaSet is scaled down to 60%. A Replicaset is a K8s object, a set of Pod templates that describe a set of Pod replicas. Let’s first take a look at how should we create a ReplicaSet. When an HPA is enabled, it is recommended that the value of spec. By evaluating pod. Deployment is nothing but the higher-level of abstraction for Replicaset. 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. Exposing the ReplicaSet. Implementation mechanism of garbage collection. kubectl -n eks-sample-app describe service eks-sample-linux-service. When both configured some unexpected behaviour might arise. revisionHistoryLimit is an optional field that specifies the number of old ReplicaSets to retain to allow rollback. Share. Once your Pods have started, you can scale the StatefulSet up or down without risking the destruction of the MySQL primary node. While ReplicaSets can be used independently, today they're mainly used by Deployments as a mechanism to orchestrate Pod creation, deletion and updates. Kubernetes provides a guarantee that the established Pod order will be respected. The straightforward way to achieve this is to create a service object that exposes the deployment. Note: In Kubernetes, Deployments don’t manage Pods directly. Once your Pods have started, you can scale the StatefulSet up or down without risking the destruction of the MySQL primary node. This is where PDB s provide the added advantage over the Replicaset. Tested the field as below. g. In Kubernetes, the Deployment resource is a declarative approach for managing the Pod and ReplicaSet resources. The Deployment is scaling down an existing ReplicaSet. Avoid complexity when possible, but let your application requirements dictate the architecture. kubectl create --help |awk '/Available Commands:/,/^$/' Available Commands: clusterrole Create a cluster role clusterrolebinding Create a cluster role binding for a particular cluster role configmap Create a config map. Share. (No need for. ReplicaSet is the next-generation ReplicationController that supports the new set-based label selector. # kubectl describe rs soaktestrs Name: soaktestrs Namespace: default Image(s): nickchase/soaktest Here you see that when you first created the Deployment, it created a ReplicaSet (nginx-deployment-2035384211) and scaled it up to 3 replicas directly. And Replica Set manages the basic units in Kubernetes - Pods. It creates a selector that matches to matchLabels. The . これまで、Pod、ReplicaSetの動作を確認してきましたので、今回はDeploymentの動作を確認します。 Deploymentは、ReplicaSet、Podの上位概念で、以下のような関係になります。 Deploymentの作成 yamlファイルの作成とapply. I am new to kubernetes and trying to create a deployment. In this case, the Deployment will run only one Pod of your application. but the problem is i need to clean all old deployment and replica set once new version deployed successfully. Pods are ephemeral wrappers responsible for running one or more containers that have resource requests for a worker node in your cluster. Create a Deployment to rollout a ReplicaSet. Note: a Deployment’s rollout is triggered if and only if the Deployment’s pod template (i. This way you could either, name the stateful-set according to the classes, i. Let's deploy your front-end application using a deployment object. A standalone mongod instance is useful for testing and development. Convert an existing standalone mongod instance into a three-member replica set. The deployment will indicate the current "revision" of the replica set with the deployment. リソース 役割; Deployment: ReplicaSetを生成、管理しローリングアップデートやロールバックといったデプロイ管理を行います。: ReplicaSet: 同じ仕様のPodのレプリカ数を管理します。ReplicationControllerの後継に当たるものです。: Pod: アプリケーションを動かすための最小単位。To make changes in your current deployment you can use kubectl rollout pause deployment/YOUR_DEPLOYMENT. For Deployment, ReplicaSet, Replication Controller, only scale, if the number of existing replicas matches. Deployments have two main disadvantages compared with StatefulSets and DaemonSets. mongosh --port 28015. The interesting thing here is that when there is pod that actually matches the selector labels of the RS without. The desired replica of the old. Understanding Deployment s. To create a ClusterIP service (default), use the following command: $ kubectl expose deployment nginx-deployment –name my-nginx-service –port 8080 –target-port=80. The ReplicaSet will notice the Pod has vanished as the number of container instances will drop. In the case of a Job, this option is ignored. string. Deployment membuat ReplicaSet baru. In this example, the label selected is nginx-appas defined in the pod template. Pod ：1つ以上のコンテナからなる集合体（Kubernetes上でコンテナを管理する最小単位）. Aunque que los ReplicaSets puede usarse independientemente, hoy en día se usan principalmente a través de los Deployments como el mecanismo. Note: we can ignore the service named kubernetes in the example above; that one already did exist before our kubectl run command. A pod is the smallest unit of deployment in Kubernetes, consisting of one or more containers that share resources and networks. 一个 Deployment 为 Pod 和 ReplicaSet 提供声明式的更新能力。. Here the replicas field is set to 3, but you can set it to whatever fits your application. The second line is when I triggered the update. Overview. In the previous example, we scaled up the NGINX pods. 式的定义方法，在 Deployment 对象中描述一个期望的状态，Deployment 控制器就会按照一定的控制 速率把实际状态改成期望状态，通过定义一个 Deployment 控制器会创建一个新的. // +optional CollisionCount *int32 `json:"collisionCount,omitempty" protobuf:"varint,8,opt,name=collisionCount"` }It seems a deployment has gotten stuck. It's mainly used by Deployment as a. In your terminal, change to the directory where you saved the deployment file, and run: $ kubectl apply -f The above command will create the deployment with two pods. It is declarative and can be used for rolling updates of micro. If you see the logs, they are starting from 73, meaning that the previous pod had written till 72 in the file and. In docs about owners and dependents it says:. In the case of a Job, update parallelism only if the current parallelism value matches. Deployment creates ReplicaSet with the number of replicas=3. 2. A ReplicaSet is a process that runs multiple instances of a Pod and keeps the specified number of Pods constant. integer. The Scheduler, that is in charge of the pod resource allocation, commnd the kubelet, which reside on every worker nodes,. After the deployment starts, you find a new KUBERNETES OBJECT STATUS tab next to the TASK LOG tab. We are using Kubernetes 1. The . schedulerName field of the DaemonSet. Behind the scenes, Kubernetes stored numbers of old ReplicaSet so that you can switch to any Replicaset anytime. Hostname and port of a mongod process. Whether you’re rolling an update or rollbacking one, using the deployment helps you handle Pod instances better. This is how the deployment is usually rolled out. ReplicaSet ：同じ仕様のPodを期待する数に維持するオブジェクト. replicas field. However, more sophisticated selection rules are possible, as. This manifest will define the desired state of the ReplicaSet, including the pod template for your application. yaml replicaset "soaktestrs" created Check the Status of a ReplicaSet Once the ReplicaSet is created, we can use the describe command to check the status of the pods and get more detail. 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. The nodeapp-deployment is the deployment name which is already. Without this hash, when a Deployment specs are updated and a new ReplicaSet needs to be created, how would it be distinguished from the previous one? I think this is not a matter of overlapping ownership of objects, it is more of a matter of overlapping specs. When you create a deployment, the template is needed for creationupdate of ReplicaSet and PODs, in this case, they need to match the selector, otherwise you would end up with orphan. There is this thing called inter pod anti affinity that does exactly this. 4 or later. kubectl label nodes <node> <key>=<value>. Provide a URL for accessing the API. kubectl apply -f dp. Create a DaemonSet. After it's paused you can make necessary changes to your configuration and then resume it by using kubectl rollout resume deployment/YOUR_DEPLOYMENT. Accordingly Replicaset is owned by Deployment Alternatives to ReplicaSet: Deployment (recommended). To verify the number of Pods, run the $ kubectl get pods command. ReplicaSet is the next-generation ReplicationController that supports the new set-based label selector. How Deployment uses spec. When this ReplicaSet is created it will start the desired number of Pods from the template. kubectl delete <component type> <name> <-n namespace>. Sometimes, Kubernetes sets the value of ownerReference automatically. ( i. – moonkotteA Deployment is used to spin and scale stateless applications while saving the state of the ReplicaSet it manages in a persistent volume, so that all pod replicas share the same volume. Or by using YAML: apiVersion: v1. Un ReplicaSet (ensemble de réplicas en français) a pour but de maintenir un ensemble stable de Pods à un moment donné. This option is mandatory as we aren’t updating the value of the spec. The Deployment can manage multiple ReplicaSets in order to perfom rolling update of the. When you install your database nodes, always use clean and minimal VMs. While ReplicaSets can be used independently, today they’re mainly used by Deployments as a mechanism to orchestrate Pod creation, deletion and updates. The following is an example ReplicaSet definition: apiVersion: apps/v1 kind:. The running instances are located in multiple locations. A Deployment resource uses a ReplicaSet to manage the pods. 0. Then gradually it decreases the count of replicas from the previous ReplicaSet and increases the count on the current one until the latter ReplicaSet has all the Pods. It manages the deployment of ReplicaSets and allows for easy updating of a ReplicaSet as well as the ability to roll back to a previous version of deployment. For Deployment, ReplicaSet, Replication Controller, wait for the status value of ready_replicas to change to the number of replicas. ReplicaSetCondition describes the state of a replica set at a certain point. The Deployment creates a ReplicaSet that creates three replicated Pods, indicated by the . I found a guide that uses vanilla manifests for MongoDB deployment. Once the MongoDB resource is created, the operator will deploy a new. Whenever, you made some changes in deployment's podTemplate, it creates a new replicaset. Like deployment replicaset cant rollout or rollback to different version of application nor maintain any revisions for the same. Deployment is an abstraction over ReplicaSet. A replica set is a core Kubernetes object called ReplicaSet. To get the name just read the environment variable HOSTNAME. yaml, this will instruct Kubernetes to scale the current number of Pods to the value of. It maintains a ReplicaSet with the desired configuration, with some additional configuration for managing updates and. And only after some googling I found this post on Medium:. Unlike a. The number of ready replicas for this replica set. They are composed of the following separate API objects:. So first I created a replicaset named rs. ReplicaSet is not suitable for applications that are going to have rolling updates and rollbacks. For now I'm able to increase the replicas from CLI using the command: kubectl scale --replicas=3 deployment my-deployment. the pod template specified inside the Deployment's yaml file, and the value of the replica field (which define the size of the pod set). $ kubectl apply -f deployment. As per the name, ReplicaSet is used for managing the replicas of our pods. PodとReplicaSetが再作成されました。. Create a Service. Use when strategy = canary. It gives us fine-grained control over how and when a new pod version is rolled out. Un ReplicaSet (ensemble de réplicas en français) a pour but de maintenir un ensemble stable de Pods à un moment donné. Now we’ll create a Kubernetes service using our deployment from the previous section. ET. Add an arbiter to give a replica set an odd number of voting members to prevent election ties. It also needs to check whether the target pod is already managed by another controller (like a Deployment or another ReplicaSet). After you destroy the ReplicaSet, the running Pods will also get deleted. Regarding Endpoints and Namespace Controllers. Il a ensuite poursuivi la montée en puissance du. If you want to look at all the logs for a specific deployment, use the command: kubectl logs. A ReplicaSet provides basic scaling mechanisms for pods, such as creating new pods if any pod. 15, 2023, 3:18 p. The controller verifies if the current state matches the deployment’s desired set, and creates a ReplicaSet if necessary, which then creates the pods. yaml. The ReplicaSet configuration defines a number of identical pods required, and if a pod is evicted or fails, creates more pods to compensate for the loss. configure ArgoCD / FluxCD / other deployment tool to delete them. spec. Data Directory. Assume that you have a Deployment that spawns five Pod replicas. The Deployment controller uses this // field as a collision avoidance mechanism when it needs to create the name for the // newest ReplicaSet. The replicaset with revision N-1 will be the "old" one. replicas of the Deployment and / or StatefulSet be removed from their manifest (s). Patch your deployment either by running and edit the environment field there: kubectl edit. In general, Deployment is a more powerful and feature-rich resource than ReplicaSet. Kubernetes deployments manage stateless services running on your cluster (as opposed to for example StatefulSets which manage stateful services). These sets provide redundancy and fault tolerance. Reload to refresh your session. It can. When you update a Deployment, it will update the ReplicaSet, which in turn updates the Pods. Deployment 是 kubernetes 中最常用的资源对象，为 ReplicaSet 和 Pod 的创建提供了一种声明. Replica Count: The number of replicas (pods) the controller should always be. Deployment adds flexibility to your Kubernetes cluster and eventually, to your application. The . To learn more about replica sets, see the Replication Introduction in the MongoDB manual. The number of pods that have labels matching the labels of the pod template of the replicaset. The pod-template-hash label is added by the Deployment controller to every ReplicaSet that a Deployment creates or adopts. OwnerReferences[0]. StatefulSet (stable-GA in k8s v1. To deploy a replica set using an object, you must: Have or create an Ops Manager instance or a Cloud Manager organization. ReplicaSet. Here we go. I guess Deployments and ReplicaSets will. selector field defines how the created ReplicaSet finds which Pods to manage. A DeploymentConfig (DC) in OpenShift is more or less equivalent to a Kubernetes Deployment, nowadays. This is where you specify how the ReplicaSet should. You signed in with another tab or window. StatefulSet で作成された Pod は、それぞれ単一の PV をマウントしています. Kubernetes events are a resource type in Kubernetes that are automatically created when other resources have state changes, errors, or other messages that should be broadcast to the system. The simplest method that comes to mind when we need to run a Singleton Pod in Kubernetes is a ReplicaSet. More information Before you. Update the replica set configuration when the hostname of a member's corresponding mongod. kubectl delete deployment $ {our-deployment-name} And this seems to delete the deployment called our-deployment-name fine. Tiếp. This hostname can be a hostname, an FQDN, an IPv4 address, or an IPv6 address. 9) is a Kubernetes resource used to manage stateful applications. The ReplicaSet uses a pod template with the app: web-app label, and the pod specification includes a container named web using the nginx image with specified resource limits and requests. A Deployment is the preferred way to deploy an application inside a pod. kubectl delete deploy inginx-deploy. How can I diagnose this further?. apiVersion: extensions/v1beta1 kind: Deployment metadata: name: nginx. ownerReferences" field with the ID of that ReplicaSet. Declarative config management. # deployment name and namespace deployment_name=mydeployment deployment_ns=mynamespace # get replica set identifier for deployment dep_rs=$. This annotation is set by Kubernetes. StatefulSets. 1. 1 Answer. When you revise a deployment, a ReplicaSet is created that. StatefulSets. The rules are of the form "this pod should (or, in. The standard replica set deployment for a production system is a three-member replica set. Deployment with name backend is created indicated by metadata. # Create the MySQL StatefulSet using deployment we can undo deployment, pause deployment, resume deployment. This is different from vertical scaling, which for Kubernetes would. Deployment creates ReplicaSet with the number of replicas=3. Without it, ReplicaSet might create new pods when existing pods are deleted. You cannot create any Deployment (RelicaSet) without container properties description (images, volumes etc. In mongosh, use rs. In this case, you select a label that is defined in the Pod template (app: nginx). It increases the pods one by one while the old replicaset decreases the pods one by one. 1. Puedes monitorizar el progreso de un Deployment usando el comando kubectl rollout status. To specify a port to connect to on localhost, you can use either: A connection string with the chosen port. For Deployment, ReplicaSet, Replication Controller, only scale, if the number of existing replicas matches. Deployment adalah sebuah objek yang bisa memiliki ReplicaSet dan memperbarui ReplicaSet dan Pod-nya melalui rolling update deklaratif dan server-side. For all intents and purposes just use Deployments now. They let you perform rolling updates of ReplicaSets, where Pods are rescheduled without any service downtime. Bare pod. Ops Manager initially groups each process under the replica set name. While ReplicaSets can be used independently, today they're mainly used by Deployments as a mechanism to orchestrate Pod creation, deletion and updates. selector. StatefulSet is also a Controller but unlike Deployments, it doesn’t create ReplicaSet rather itself. This is the same result for another. to the left of the replica set name to display all mongod processes in the replica set. Kubernetes deployment drawbacks. Deployment is a higher-level concept that manages ReplicaSets and provides declarative updates to Pods. 8. Add a new member to an existing replica set. ReplicaSet có số lượng pod mong muốn (DESIRED) là 10, và số lượng Pod hiện tại (CURRENT) là 10. For example, the following commands connect to a deployment running on localhost port 28015: mongosh "mongodb://localhost:28015". Click the. # deployment name and namespace deployment_name=mydeployment deployment_ns=mynamespace # get replica set identifier for deployment dep_rs=$ (kubectl describe. default 22m 22m 1 wordpress-686ccd47b4. On the deployment configuration editor page or in the fromimage page of the web console, set the Pull Secret. Add a comment. Replica Count: The number of replicas (pods) the controller should. Most objects in Kubernetes have a metadata, it is responsible to store information about the resource like, name, labels, annotations and so on. of pods as mentioned in the yaml file. The deployment file contains details for a ReplicaSet that includes a PodTemplate. io/revision: "4" This will exist on both the deployment and the replicaset. nodeAffinity field (if specified) is taken into consideration by the DaemonSet controller when evaluating the eligible nodes, but is. Choices: false. yml. To estimate cost for. A ReplicaSet is a Kubernetes object that ensures that a specified number of replicas of a pod are running at any given time. Deployment では、全てのPodで1個のPV をマウントしている違いがあります. 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. A Deployment owns and manages one or more ReplicaSets. replicas field. Imperative config management with commands. selector to know what Pods it should manage. Deployment is a good fit for managing a stateless application workload on your cluster, where any Pod in the Deployment is interchangeable and can be replaced if needed. template) is changed. Each of these objects is abstractions with different responsibilities;. kind: Deployment name: php-apache minReplicas: 1 maxReplicas: 10 targetCPUUtilizationPercentage: 50. spec. There are many private registries in use. This item links to a third party project or product that is not part of Kubernetes itself. Despite both controllers being instrumental in managing high-availability. As such, a deployment is generally the best option for any service that needs to maintain high availability, as it intelligently tears down services in the event of a change to the desired state of the system so that it doesn’t interrupt any service. I want a Replica. trafficSplitMethod - Traffic split method string. the pod template specified inside the Deployment's yaml file, and the value of the replica field (which defines the size of the pod set).
