Pods consume node resources and PVCs consume PV resources. It is useful for our database deployment.Ī PersistentVolumeClaim (PVC) is a request for storage by a user. ( bmc.com)Ī Persistent Volume (PV) is a piece of storage in the cluster that has been provisioned by an administrator or dynamically provisioned using Storage Classes. Those containers all share a unique network IP, storage, network, and any other specification applied to the pod. Inside a pod, you can have one or more containers. In a Kubernetes cluster, a pod represents a running process. Deployments represent a set of multiple, identical Pods with no unique identities( gcloud).Ī Kubernetes pod is a group of containers that are deployed together on the same host. Deployments are managed by the Kubernetes Deployment controller. In this way, Deployments help ensure that one or more instances of your application are available to serve user requests. These are some:Ī Deployment runs multiple replicas of your application and automatically replaces any instances that fail or become unresponsive. It is important to understand kubernetes terms. It is also pretty simple to install on any other OS, you can browse about that. If you are on macOS, install using it brew: brew cask install virtualbox This is required in order to start and run minikube To install and set up kubectl, follow this guide. You can use kubectl to deploy applications, inspect and manage cluster resources, and view logs. Kubectl (Kubernetes command-line tool): allows you to run commands against Kubernetes clusters. To install and setup minikube, follow this guide. Minikube runs a single-node Kubernetes cluster inside a Virtual Machine (VM) on your laptop for users looking to try out Kubernetes or develop with it day-to-day ( kubernetes.io). Minikube is a tool that makes it easy to run Kubernetes locally. You can get the code for this article here.īut if you want to follow step by step from article 2, where we dockerized our application, clone the repo. We will deploy our awesome API on a local kubernetes cluster using minikube. Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications ( kubernetes.io) Kubernetes Features Get article 2 here and the github here Introduction This is the third part of the article series.

Welcome! In this article, we will deploy our API to Kubernetes.
