What is the difference between a pod and a deployment?
As we now know, a pod is the smallest unit of Kubernetes used to house one or more containers and run applications in a cluster, while deployment is a tool that manages the performance of a pod. This is where deployments come in; defining the number of copies of a specific pod.22 Dec 2021
What are the types of deployment in Kubernetes?
- recreate: terminate the old version and release the new one.
- ramped: release a new version on a rolling update fashion, one after the other.
- blue/green: release a new version alongside the old version then switch traffic.
What is the difference between StatefulSet and deployment in Kubernetes?
A StatefulSet is another Kubernetes controller that manages pods just like Deployments. But it differs from a Deployment in that it is more suited for stateful apps. A stateful application requires pods with a unique identity (for example, hostname). One pod should be able to reach other pods with well-defined names.
How does Kubernetes Deployment work?
A Kubernetes Deployment is used to tell Kubernetes how to create or modify instances of the pods that hold a containerized application. Deployments can scale the number of replica pods, enable rollout of updated code in a controlled manner, or roll back to an earlier deployment version if necessary.
How do I start a deployment in Kubernetes?
Creating Deployments You can create a Deployment using the kubectl apply , or kubectl create commands. Once created, the Deployment ensures that the desired number of Pods are running and available at all times. The Deployment automatically replaces Pods that fail or are evicted from their nodes.
What is difference between service and deployment in Kubernetes?
What's the difference between a Service and a Deployment in Kubernetes? A deployment is responsible for keeping a set of pods running. A service is responsible for enabling network access to a set of pods. The deployment could be scaled up and down and pods could be replicated.
How services work in Kubernetes?
What is a Service in Kubernetes? A Service enables network access to a set of Pods in Kubernetes. Services select Pods based on their labels. When a network request is made to the service, it selects all Pods in the cluster matching the service's selector, chooses one of them, and forwards the network request to it.
What are the types of Deployments?
Which Deployment Strategy Should You Use: Basic, Multi-Service, Rolling, Blue/Green, Canary, A/B Testing? Whether we mean to or not, software deployments look different across organizations, teams, and applications.
