If the pod template includes a volume, which refers to a specific PersistentVolumeClaim, all replicas of the ReplicaSet will use the exact same PersistentVolumeClaim and therefore the same PersistentVolume bound by the claim (shown in figure 10. A ReplicaSet is a key component of a Kubernetes application. Report this post INSPIRAS 1,078,188 followers 1yDaemonSet. Trivy Github Security Scan. Chúng ta sẽ tạo một DaemonSet đơn giản, đầu tiên chúng ta cũng chuẩn bị file ds_sample. This cheatsheet will serve as a quick reference to make commands on many common Kubernetes components and. All three of these are defined via YAML configuration. 1 Answer. , the byte at offset x in the pseudo-file is the same as the byte at address x in the process. See full list on semaphoreci. ReplicaSets have a . Rollback to an earlier Deployment revision if the current state of the Deployment is not stable. Listing all the pods belonging to a deployment can be done by querying its selectors, but using the deployment’s synthesized replicaset identifier allows for easier automation. # deployment name and namespace deployment_name=mydeployment deployment_ns=mynamespace # get replica set identifier for deployment dep_rs=$. The main difference between a Replica Set and a Replication Controller right now is the selector support. yaml. Replicate Kubernetes Ingress using plain Nginx and Docker Compose in less than 5 minutes #kubernetes #ingress #nginx #docker #dockercompose #proxy…Day 23- Kubernetes DaemonSet #kubernetes #daemonset #keyfeatures #usecases #handson Client Certificates for Normal Users. C. Horizontal scaling means that the response to increased load is to deploy more Pods. Does not matter in which worker node they are running. I like to call it as “run everywhere thing” when I introduce it to newbies. The DaemonSet can be looked down upon by a lot of people for its subjectively resource-intensive approach to Pod replication but used. --. In DaemonSet mode, the Logtail installed by default is in the kube-system namespace. #TrendMicroOne, a unified #cybersecurity platform, provides recommendations. This wouldn’t be possible if a Deployment or ReplicaSet was used, as scheduling or replication changes would. 2. kubectl label node <node-name> key=value. kubectl get nodes. Kubernetes is also known as K8s is an open-source container orchestration tool developed by google which is used for automating software deployment, scaling, and management. Kubectl is the command line configuration tool for Kubernetes that communicates with a Kubernetes API server. kubectl get pods Scaling Application: We can scale the application after created in various ways. Building on replication controllers, OpenShift Container Platform adds expanded support for the software development and deployment lifecycle with the concept of deployments. Figure 6: Group of requests in a DaemonSet and single concern for Sidecar. This means if you have lots of replicas, you are putting. These might be fundamental to the operation of your cluster, such as a networking helper tool, or be part of an add-on. A new ReplicaSet is created and the Deployment manages moving the Pods from the old ReplicaSet to the new one at a controlled rate. Podの雛形 (Pod Template)を定義し、Label Selectorという方法で管理対象を. For example, a log collector daemon gathering log data from all the other programs. To get the yaml file try kubectl get deploy deploymentname -o yaml To update the pod with the new yaml file first either find and edit the yaml file or copy the contents and make the changes you want to make, then run: kubectl apply -f newDeployment. Use daemonsets to create shared storage, run a logging pod on every node in your cluster, or deploy a monitoring agent on every node. namespaces. Algunos casos de uso. DaemonSet is a k8s construct that allows exactly one instance of pod running in each node in the cluster. com A ReplicaSet is defined with fields, including a selector that specifies how to identify Pods it can acquire, a number of replicas indicating how many Pods it should be maintaining, and a pod template specifying the data of new Pods it should create to meet the number of replicas criteria. 26. The ReplicaSet can then establish the Pods it controls, so it knows whether the minimum availability target has been met. After the DaemonSet is created, any updates to a RollingUpdate DaemonSet . Also, the DaemonSet controller will use the original template the next time a node (even with the same name) is created. DaemonSet là một dạng dịch vụ quản lý các Pod hoạt động với chức năng khá là riêng biệt bằng cách đảm bảo Pod dịch vụ sẽ được chạy trên toàn bộ các Node trong một Kubernetes Cluster (hoặc trên một số Node cụ thể trong Kubernetes. Check. This is useful in multi-tenant environments where you must isolate tenants from each other or when you want to create separate environments for development, staging, and production. Except for the out-of-resources condition, all these conditions should be familiar to most users; they are not specific to Kubernetes. spec. Deployment options. While the earlier controller types ensure that a specific number of replicas are running across the cluster, DaemonSets are intended to run exactly one pod per node. Understanding ReplicaSet vs. Rollback to earlier deployment revision - If due to some circumstance, the current state doesn’t turn out to be stable, then the deployment can be. replication controllers are deprecated and is not recommended any more. Understanding ReplicaSet vs. StatefulSets. DaemonSet vs. To remove a DaemonSet, use the kubectl delete command (for example, kubectl delete –f example-daemon. there are many differences between how DaemonSet and ReplicaSet are managed, but the main ones are as follows. - state_node - state_deployment - state_replicaset - state_pod - state_container period. Usa un DaemonSet en vez de un ReplicaSet para aquellos Pods que proporcionan funcionalidad a nivel de servidor, como monitorización de servidor o logging de servidor. Gunakan DaemonSet alih-alih ReplicaSet untuk Pod yang menyediakan fungsi pada level mesin, seperti monitoring mesin atau logging mesin. DaemonSet. If it succeeds, the command returns: daemonset "<daemonset-name>" rolled back. use the node affinity/anti-affinity and/or node selector to control the set of nodes to run on (similar to how DaemonSet does it). LAB-8 Replicaset. DaemonSets guarantee a single instance of a pod runs on each eligible node. 14 [stable] Pods can have priority. For kinds in the extensions/v1beta1, apps/v1beta1, and apps/v1beta2 group versions, unless you specify otherwise, dependent objects are orphaned by default. With Calico network policy enforcement, you can implement network segmentation and tenant isolation. Implement distributed tracing with Jaeger & Opentelemetry on Kubernetes #kubernetes #distributedtracing #opentelemetry #jaeger #microservices…Saket Jain. ReplicaSet is a lower-level abstraction that provides basic scaling mechanisms. What is the difference between a StatefulSet, a Deployment, and a DaemonSet? Stateful vs. 6 Kubernetes Deployment Strategies: Roll. e. Where a ReplicaSet. Creates an autoscaler that automatically chooses and sets the number of pods that run in a Kubernetes cluster. What is the difference between them. Utilisez un DaemonSet au lieu d’un ReplicaSet pour les pods qui fournissent une fonction au niveau du noeud, comme le monitoring ou la gestion des logs de ce noeud. spec. Television. Reading the documents it is not clear if the default behaviour should. Unlike a Deployment, a StatefulSet. DaemonSet. The difference between StatefulSets and Deployments reflects the divide between stateful and stateless systems. If a node is added/removed from a cluster, DaemonSet automatically adds. DaemonSets. How Deployments, Statefulsets & Daemonsets work. Node affinity is a property of Pods that attracts them to a set of nodes (either as a preference or a hard requirement). In Kubernetes, the Namespace object provides a way to create isolated environments within a cluster. apps/kuard created $ kubectl get deployment,replicaset,pod --show-labels NAME DESIRED CURRENT UP-TO-DATE AVAILABLE AGE LABELS deployment. The Log Analytics workspace ID and key configured on the containerized agent match with the workspace that the insight is configured with. Next, tell Kubernetes to drain the node: kubectl drain --ignore-daemonsets <node name>. StatefulSet. If a Pod from the ReplicaSet fails, it automatically creates an additional Pod from the. From my understanding replicaset ensures there is only a set amount of. daemonset. In this example: A Deployment named nginx-deployment is created, indicated by the . StatefulSets will deploy the desired number of Pods to any available. You can see it by running: $ sudo microk8s kubectl get daemonset -n ingress nginx-ingress-microk8s-controller -o yaml. Job. DaemonSet vs. There is no difference between Replication Controller and Deployment for this case (after all a Deployment is just a wrapper around a Replica Set). 16 DevOps Best Practices to Follow. For example, let’s say you want to label a node as. yml deployment. The DaemonSet is named logtail-ds, and the Logtail pod on each node is responsible for collecting data (including stdout and files) of all running pods on this node. Deployments #kubernetes #controllers #replicaset #statefulset #daemonset #deployments… Beliebt bei Asel Şeşen The blue book, by Eric Evans, is a must. StatefulSet vs. There is no difference between Replication Controller and Deployment for this case (after all a Deployment is just a wrapper around a Replica Set). A request for more than one time-sliced GPU does not guarantee that the pod receives access to a proportional amount of GPU compute power. Manages the deployment and scaling of a set of Pods, and provides guarantees about the ordering and uniqueness of these Pods. stateless applications. DaemonSet vs. Any non-bare pod will be recreated on a new node by its respective controller (e. 0. Refer below code and add. Production-Grade Container Scheduling and Management. StatefulSet is the workload API object used to manage stateful applications. Let’s talk about our final set type: a DaemonSet. StatefulSet vs. The. DaemonSet. DaemonSet. A DaemonSet is a Kubernetes resource that ensures a specified Pod runs on all nodes or a specific subset of nodes in a cluster. However, the official Kubernetes documentation provides little guidance on apiVersion. Also, static Pods may be deprecated in the future. Each pod in a DaemonSet performs a job similar to a system daemon on a classic Unix / POSIX server. Posted on 14/05/2021. Now get the Pods list using the following command. $ kubectl drain foo --grace-period=900 Options: --delete-emptydir-data=false: Continue even. Algunos casos de uso típicos de un DaemonSet son: Ejecutar un proceso de. 9. The first building block is a pod, which is, in turn, used in ReplicaSets. (Allows more disruptions at once). template will trigger a rolling update. In Kubernetes, a HorizontalPodAutoscaler automatically updates a workload resource (such as a Deployment or StatefulSet), with the aim of automatically scaling the workload to match demand. In ch 4. By evaluating pod. In this case, all DaemonSet objects are reconciled each time a Node is created. Both Application Load Balancer and Network Load Balancer are designed from the ground…The Azure Monitor metrics agent's architecture utilizes a ReplicaSet and a DaemonSet. 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. Kubectl Command Cheatsheet. Read more: Kubernetes Daemonset: A Practical Guide. Currently, it is being maintained by the cloud native computing foundation (CNCF). There is one other type ReplicationController but Kubernetes now favors Deployments as Deployments configure. Un ReplicationController garantiza que un número determinado de réplicas se estén ejecutando en todo momento. Using Kubectl allows you to create, inspect, update, and delete Kubernetes objects. Although they had. Step 2: Roll back to a specific revision. replicaset. As nodes are removed. That rejection happens asynchronously from the creation, and is indistinguishable from something deleting the pods for unrelated reasons. StatefulSet vs. The Azure Monitor Agent Health service is running. Close navigation. Command used to delete kubernetes namespace named “my-namespace” in a Kubernetes cluster. Use a Job instead of a ReplicaSet for Pods that are expected to terminate on their own (that is, batch jobs). Here are a couple from my canal daemonset: tolerations: - effect: NoSchedule operator: Exists - key: CriticalAddonsOnly operator: Exists - effect: NoExecute operator: Exists. The kubernetes kubelet runs on each node and keeps the other pods on the node running. As you said, DaemonSet guarantees one pod per node for a subset of the nodes in the cluster. DaemonSets are used to deploy system daemons such as log collectors and monitoring agents, which typically must run on every node. daemonset and deployment can be primarily. Use a Job instead of a ReplicaSet for Pods that are expected to terminate on their own (that is, batch jobs). Kubernetes API is growing day by day and they are adding new features every day. Each rollback updates the revision of the Deployment. It is declarative and can be used for rolling updates of micro. 9) is a Kubernetes resource used to manage stateful applications. These pods have a lifetime that is tied to a machine lifetime: the pod needs to be running on the machine before other pods start, and are safe to terminate when the machine is. 4 of Kubernetes In Action by Marko Luksa, he says the kube-proxy is a DaemonSet but doesn't explicitly state that. The application pods use the service mesh pod on the same node as a proxy for all requests. Sorted by: 7. --force will also allow deletion to proceed if the managing resource of one or more pods is missing. ReplicationController $ kubectl scale --replicas=3 rc/demo-replicationcontroller. The Azure Monitor Agent replicaset pods are running. At most one pod of the. Tolerations allow scheduling but don't. A DaemonSet allows you to overcome Kubernetes’ scheduling limitations and makes sure that a specific app gets deployed on all the nodes within the cluster. If a DaemonSet Pod must run on specific Nodes, instead of all Modes, label selectors help identify the Nodes to run on. DaemonSet is a Kubernetes controller used for cluster-level operations, ensuring that a specific Pod runs on every node in the cluster. ReplicaSet $ kubectl scale --replicas=3 rs/demo-replicaset. You can not control its replica using scale option. This can. When DaemonSet is deployed, it will create pods equal to the number of nodes. It is the kube-controller-manager under which kubernetes is running several type of controllers. , you can achieve something similar by scaling the number of container replicas you're running. The minimum management object in a cluster is a pod. With RollingUpdate update strategy, after you update a DaemonSet template, old DaemonSet pods will be killed, and new DaemonSet pods will be created automatically, in a controlled fashion. yaml. io/zone and the value of that label must be either antarctica-east1 or antarctica-west1. As nodes are added to the cluster, Pods are added to them. Deployments. Tolerations allow the scheduler to schedule pods with matching taints. You should be cautious when specifying the name of the DaemonSet file as deleting a DaemonSet will clean up all the pods it has deployed. A new ReplicaSet is created and the Deployment manages moving the Pods from the old ReplicaSet to the new one at a controlled rate. Next steps. What is ReplicasSets? A ReplicaSet is a process that runs multiple instances of a Pod and keeps the specified number of Pods constant. You can use --help after the subcommand to get additional info about possible parameters (for example: kubectl get nodes --help). ·. DaemonSets are great for running a single instance of an application on every node in the cluster. This helps to ensure that the DaemonSet is present on each node without triggering node recreation. Por ejemplo, si creamos un StatefulSet con el nombre counter, se creará un pod con el nombre counter-0, y para múltiples réplicas de un StatefulSet, sus nombres se incrementarán como counter-0, counter-1, counter-2, counter-3, etc. If you want to create a secret form the file, then use the. Create a deployment. StatefulSets vs. This answer isn’t all that helpful. StatefulSets. Understanding ReplicaSet vs. 5. (ReplicaSet extends an older object called ReplicationController-- which is exactly the same but without the Revision history. StatefulSet $ kubectl scale --replicas=3 sts/demo-statefulset 基础缩放 现在我们将看一个使用kubectl scale扩展部署的完整示例。这是一个定义简单部署的 YAML 文件. 아울러 이들의 실행 구역을 논리적으로 분할하는 네임스페이스(Namespace)의 역할도 함께 들여다 본다. This guide gives you. QoS classes are used by Kubernetes to decide which Pods to evict from a Node experiencing Node Pressure. g. For this the recommended approach is to use a Deployment, which under the hood create a ReplicaSet. DaemonSet vs. The Replication Controller is the original form of replication in Kubernetes. You can also configure it to scrape any custom targets at the node level with static configs. Use a DaemonSet instead of a ReplicaSet for Pods that provide a machine-level function, such as machine monitoring. Command used to. As nodes are removed from the cluster, those. Kubernetes API is growing day by day and they are adding new features every day. Xin chào các bạn, chúng ta lại tiếp tục với series k8s basic để cùng nhau làm quen với k8s. For example, if you have 3 nodes, it will schedule 3 DaemonSets one for each node. 1. kind from deployment to daemonset without reinstalling from the very beginning?Deploy a DaemonSet with a HostPath. In preparation for my CKA exam, I…A new ReplicaSet is created and the Deployment manages moving the Pods from the old ReplicaSet to the new one at a controlled rate. With ReplicaSet you define number of replicas you want to run for a specific application or a service. ReplicaSetについて. ; Now, get the Pods and pass the --show. This way the deployment will be marked as paused and won't be reconciled by the controller. Labels can be used to organize and to select subsets of objects. Deploying a Sample ReplicationSet in Kubernetes. Understanding ReplicaSet vs. A DaemonSet is a higher-level abstraction designed to ensure that a specific pod runs on all nodes in a cluster or on a subset of nodes based on specified criteria. Use a DaemonSet instead of a ReplicaSet for Pods that provide a machine-level function, such as machine monitoring or machine logging. This is important for a few reasons: It ensures that the Ingress Controller is always available to serve traffic, even if a node fails. At most one. // +optional CollisionCount *int32 `json:. StatefulSets. use inter-pod anti-affinity to spread the pods across the nodes. A DaemonSet is an efficient way to deploy containers on multiple servers inside a Kubernetes cluster. The first thing is we need to have a ReplicaSet (deployment) with 30 pods (3 per node). Change this value and apply the updated ReplicaSet manifest to your cluster to have Kubernetes reschedule your Pods to match the new. Podを配置したくないNodeがあるときはnodeSelector,Node Anti-Affinity. Like a Deployment, a StatefulSet manages Pods that are based on an identical container spec. 2 Answers Sorted by: 4 Replica Controller Vs Replica Set The functionality of both Replica Controller and Replica Set are quite the same - they are responsible to. As a DaemonSet to ensure that there’s a running instance on each node of the cluster. Job, ReplicaSet,Deployment & DaemonSet supports Set-based selectors. A Daemonset is not going to run a couple of reproduction per node. 3 Answers. Nota: Los StatefulSets son estables (GA) en la versión 1. Delete the ReplicaSet Let's clean up before we move on. sharma@knoldus. Pipe is used to. Although they had ReplicaSet, DaemonSet is the K8 object they added. Pods by themselves don't do much, even if they're hosted on nodes. 10 min read. The ReplicaSet is responsible to manage the Pods. A ReplicaSet is used to ensure that a specific number of replicas (copies) of a pod are running at any given time, while a Deployment manages updates to a ReplicaSet by creating a new ReplicaSet with the updated pod template and gradually scaling it up while scaling down the old ReplicaSet. 이번에는 쿠버네티스의 대표적인 워크로드 리소스인 레플리카셋(ReplicaSet), 디플로이먼트(Deployment), 스테이트풀셋(StatefulSet), 데몬셋(DaemonSet)을 살펴본다. kubesec will help us to analyze the security risk for Kubernetes resources. DaemonSet. You should be cautious when specifying the name of the DaemonSet file as deleting a DaemonSet will clean up all the pods it has deployed. Submit and view feedback for. We can use nodeSelector to run the pods on some specific nodes. metadata. Create DaemonSet. A DaemonSet ensures that all (or some) Nodes run a copy of a Pod. 1 Create. It is used to automatically replace any pods that fail, get deleted, or are terminated, ensuring the desired number of replicas are always available to serve requests. Use a DaemonSet instead of a. If a Node is added, the DaemonSet will automatically add a Pod to that Node. These Pods have a lifetime that is tied to a machine lifetime: the Pod needs to be running on the machine before other Pods start, and are safe to terminate when the machine is. Kubernetes Deployment vs. With ReplicaSet you define number of replicas you want to run. 11. DaemonSet ensures that all (or some, matching a node selector) Nodes run a copy of a Pod. A daemonset can be used to run replicas of a pod on specific or all nodes in an OpenShift Container Platform cluster. ReplicaSet, DaemonSet, StatefulSet or Job, then drain will not delete any pods unless you use --force. A DaemonSet container has to service all targeted containers in a cluster node, whereas a Sidecar container can only service focus on containers in. If you subsequently create a new DaemonSet with the same selector, the new DaemonSet adopts the existing Pods. 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. For example, If you create a deployment with 1 replica, it will check that the desired state of ReplicaSet is 1 and current state is 0, so it will create a ReplicaSet,. g. Cet objet est souvent utilisé pour garantir la disponibilité d'un certain nombre identique de Pods. Share. After it's paused you can make necessary changes to your configuration and then resume it by using kubectl rollout resume. Each new ReplicaSet updates the revision of the Deployment. We run the following command in k8s. Looks up a deployment, replica set, stateful set, or replication controller by name and creates an autoscaler that uses the given resource as a reference. 9. To improve fault tolerance, instead, they should always be part of a Deployment, DaemonSet, ReplicaSet or StatefulSet. Understanding ReplicaSet vs. Use a Job instead of a ReplicaSet for Pods that are expected to terminate on their own (that is, batch jobs). you should not normally create any pods whose labels match this selector, either directly, with another ReplicationController, or with another controller such as Job. Note: If --to-revision flag is not specified, kubectl picks the most. You can do that by using Deployment/ReplicaSet in Kubernetes with hostPort. A regular ReplicaSet or Deployment would not be appropriate because you couldn't reliably identify the Pod running the primary replica. DaemonSet — to manage pods that must run on each cluster node, including existing and future nodes. kubectl delete deployment $ {our-deployment-name} And this seems to delete the deployment called our-deployment-name fine. StatefulSet vs. If you just have a Replicaset with one replica and no PodDisruptionBudget specified, the pod will be terminated and a new pod will be created on other nodes. In the replica sets, we used the selector. A DaemonSet ensures that a single instance of a pod is running on each node in a cluster. Deployments ; Red Hat Unveils Developer Hub to Boost Dev… GPS Geolocation vs IP Geolocation:. yml có nội dung dưới đây. 5 or before. – Pixel Elephant. StatefulSet vs. template. kubectl apply -f postgresql. ; You can use the operator field to specify a. Let’s start by looking at the difference between a stateful and stateless application. Alternatively, you can just use the kubectl autoscale command to accomplish the same (and it's easier!)Before getting started it is important to understand how Fluent Bit will be deployed. We can also use kubectl set image to update container image in a yaml file without applying it: kubectl set image -f definition. ETCD. Managing workload objects. Kubernetes Replication Controller vs Deployment Deployments are intended to replace Replication Controllers. BMW BMW. If I call a kubectl describe on the ReplicaSet, just the first three pod creation events are showed, all successful. Replica Set is the next generation of Replication Controller. DaemonSet controllers disregard the schedulable status of your Nodes. As you said, DaemonSet guarantees one pod per node for a subset of the nodes in the cluster. Logging agents. You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster. The default Persistent Volume provisioner will provision the volume, and we can deploy this by running the following command. The key difference between stateful and stateless applications is that stateless applications don’t “store. Every time a new node is added to a cluster, the pod is added to it, and when a node is removed from the cluster, the pod is removed. A DaemonSet is a unique kind of resource that K8s assigns to a pod for each Kubernetes node in the cluster. It also implies that create command can only be used to create a Pod. 1 /5. $ kubectl apply -f deployment. Figure 6 shows another comparison, request grouping, that we have taken into consideration in our studies. Use a Job instead of a ReplicaSet for Pods that are expected to terminate on their own (that is, batch jobs). I always retain info better when I explain concepts to myself or a teammate - you know, the rubber ducky effect . In this example, the following rules apply: The node must have a label with the key topology. Philadelphia 76ers Premier League UFC. This application is a replicated MySQL database. Next steps. Some typical uses of a DaemonSet are: running a cluster storage daemon, such as glusterd. First, you need to add a label to the node. ReplicaSets are a higher-level API that gives the ability to easily run multiple instances of a given pod. When Kubernetes has a release that updates what is available for you to use—changes something in its API—a new apiVersion is created. If a node is added/removed from a cluster, DaemonSet automatically adds/deletes the pod. Step 4. 9. This page shows how to run a replicated stateful application using a StatefulSet. Create a deployment. Let’s see the difference. A DaemonSet in Kubernetes is like a chef in a restaurant. A ReplicaSet delegates local container restarts to some agent on the node such as Kubelet. For a particular service. from the cluster, those Pods are garbage collected. DaemonSets guarantee a single instance of a pod runs on each eligible node. These replicas don’t differ from each other, apart from their name and IP address. Al igual que un Deployment, un StatefulSet gestiona Pods que se basan. To remove a DaemonSet, use the kubectl delete command (for example, kubectl delete –f example-daemon. Namespace in Kubernetes can be compared to the concept of separate dining areas or private rooms in a restaurant. the node disappears from the cluster due to cluster network partition. 1. As nodes are added to the cluster, Pods are added to them. Back Submit Submitまた、ReplicaSet を使っていれば別の Node で Pod が自動的に起動される。 メンテナンス完了後、kubectl uncordonを行うことで再度 Pod がスケジューリングされる状態になる. It does this by authenticating with the Master Node of your cluster and making API calls to do a variety of management actions. In the simplest case, a deployment just creates a new replication controller and lets it start up pods. In applications of robotics and automation, a control loop is a non-terminating loop that regulates the state of the system. replicas: 2 a new ReplicaSet is created, and it observes the. schedulerName field of the DaemonSet. A new ReplicaSet is created and the Deployment manages moving the Pods from the old ReplicaSet to the new one at a controlled rate. Controller - DaemonSet. Kube-apiserver.
