kubectl apply -f https://k8s.io/examples/controllers/nginx-deployment.yaml In order to check the deployment status, run the following command: kubectl get deployments 4. Scaling: Think of Kubernetes as your trusted assistant, always ready to adjust the size of your application as needed. If ...
What is Kubernetes (k8s)? Kubernetesis an open-sourcecontainer orchestrationtool that helps in the operational management and scaling ofcontainers. Kubernetes is often abbreviated ask8s, which shortens the name to its first and last letters, with an 8 representing the eight letters between them. Ku...
The replication controller is responsible for ensuring that the number of pods deployed in the cluster matches the number of pods in its configuration. If a pod or underlying host fails, the controller will start new pods to compensate. If the number of replicas in a controller’s configuration...
Furthermore,PDBs closely interact with other Kubernetes components, such asReplicaSets,Deployments, andStatefulSets. These controllers ensure that a specified number of replicas for a pod are running at any given time. In addition, PDBs add a layer of protection by ensuring that operations affecting...
Kubernetes(aka K8s) is an open source platform used to run and manage containerized applications and services on clusters of physical or virtual machines across on-premises, public, private, and hybrid clouds. It automates complex tasks during the container’s lifecycle, such as provisioning, depl...
Once the rule is set, CSE automatically builds a normal behavior baseline for each Entity based on the rule expression. It creates a signal only when a deviation from normal behavior is detected (in this case, too many login failures compared to their normal baseline behavior). Other examples...
A ReplicaSet is primarily used with stateless applications to make sure that a specified number of identical pod replicas are always running. Here’s a table comparing ReplicaSet with StatefulSet. Creating and managing StatefulSets To learn how to set up a StatefulSet deployment, let’s look at...
An alert manager is a tool used to raise alerts based on the rules defined in Prometheus. The architecture of Prometheus in K8s Most users are deploying it with the help ofa Helm Chart, which will automatically deploy the following components in your Kubernetes cluster: ...
ReplicaSet:A ReplicaSet maintains a stable set of replica pods for specific workloads. Deployment:The deployment controls the creation and state of the containerized application and keeps it running. It specifies how many replicas of a pod should run on the cluster. If a pod fails, the deploym...
A recent LinkedIn survey found that Database as a Service (DBaaS) is the most popular choice for cloud migration. However, using Virtual Machines (VMs) on IaaS and Containers with Kubernetes (K8s) are also doing well in the market. Q: How are you moving your databases to the...
