The HPA is what you can say is the main functionality of Kubernetes and will be using mostly. HPA can change the number of replicas of a pod, scale pods to add or remove pod container collections as needed. HPA achieves its goal by checking various metrics to see whether preset thresholds...
Kubernetes Horizontal Pod Autoscaling (HPA) As explained here, Kubernetes offers the HPA on deployments. As per the docs: Horizontal Pod Autoscaling automatically scales the number of pods in a replication controller, deployment or replica set based on observed CPU utilization Google Cloud Contai...
The reason I need to add two autoscaling groups is that one of the groups has OnDemand pricing and the other has Spot pricing and one of my deployments will schedule pods in the OnDemand autoscaling group while the other will schedule pods in the Spot autoscaling group. Can I ...
Kubernetes aims to provide both resilience and scalability. It achieves this by deploying multiple pods with different resource allocations, to provide redundancy for your applications. Although you can grow and shrink your own deployments manually based on your needs, Kubernetes provides ...
Kubernetes is built to scale, and with managed Kubernetes services, you can deploy a Pod without having to worry about capacity planning at all. So why is it that Pods sometimes become stuck in an "Unschedulable" state? How do you end up with Pods that have been "Pending" for several ...
There are many ways to restart pods in kubernetes with kubectl commands, but for a start, first, restart pods by changing the number of replicas in thedeployment. In this strategy, you scale the number of deployment replicas to zero that stops all the pods and further terminates them. Pods...
Looking for more Kubernetes risks lurking in your system? Grab a copy of our comprehensive ebook, “Kubernetes Reliability at Scale.” What are CPU requests and why are they important? In Kubernetes, you can control how resources are allocated to individual Deployments, Pods, and even containers...
Step 2: Edit the Compute Environment to use EC2 Spot Instances 2.1 — By default, Elastic Beanstalk creates compute environments with an Auto Scaling group (ASG) with single instance type and on-demand purchase option. In this section, you modify the compute environment to use EC2 Spot ...
Kubernetes autoscaling is a great feature that allows you to scale your pods up or down automatically based on CPU utilization or other metrics. Autoscaling can help you maintain an optimal number of pods in your cluster, improving the performance and stability of your applications. ...
The Kubectl Scale Replicas Command A different approach to restarting Kubernetes pods is to update their environment variables. Then, the pods automatically restart once the process goes through. To restart Kubernetes pods through the set env command: ...
