Udacity Microservices at Scale using AWS & Kubernetes

In this project, we will apply our skills to build an application that connects to the Postgres database. Including:

• Works on AWS
• Use ECR to store the latest version application images
• Use Codebuild to deploy image storage to ECR automatically
• Work with CloudFormation to deploy Kubernetes infrastructure
• Use helm to deploy Postgres database
• Build a Kubernetes cluster and deploy microservices

Build Cluster kubernetes

Deploy cluster kubernetes using cloudformation

• Run aws cloudformation deploy --template-file eks.yml --stack-name eks --tags project=udapeople --capabilities CAPABILITY_NAMED_IAM to create EKS cluster

• Some kubectl commands to check k8s resources

  Fet k8s configs

  aws eks --region us-east-1 update-kubeconfig --name eks

  check all deployment

  kubectl get all

Build Postgresql

• Run helm repo add database https://charts.bitnami.com/bitnami
• helm install postgres database/postgresql

Deploy application to Kubernetes

• Run kubectl apply -f /deployment
• Show all pod, svc, deployment run kubectl get all
