This is a companion sister project of microservice-aws-eks-setup. That other project demonstrates how to automatically provision a Kubernetes cluster on AWS EKS via Terraform. Whereas, this project showcasing the automated deployment of an app/microservice to the AWS EKS cluster.

• kubectl is setup to point to the AWS EKS cluster.

• a kubconfig is setup for the AWS EKS cluster made

for e.g.

I used aws-cli to update my kubeconfig for the aws eks cluster i made in microservice-aws-eks-setup to store into ~/.kube/aws-eks-config file.

aws eks --region eu-west-2 update-kubeconfig --name microservice-aws-eks-cluster --kubeconfig ~/.kube/aws-eks-kubeconfig

Running from local machine...

Using Ansible for deployment you just run the ansible-playbook command on the CLI and pass in the nanme of the microservice to deploy as an ansible extra variable:

navigate to the ansible subfolder first.

For example, for microservice-java:

ansible-playbook deploy.yml --extra-vars "MICROSERVICE_NAME=microservice-java"

or for microservice-nodejs:

ansible-playbook deploy.yml --extra-vars "MICROSERVICE_NAME=microservice-nodejs"

For example, for microservice-java:

ansible-playbook rollback.yml --extra-vars "MICROSERVICE_NAME=microservice-java"

or for microservice-nodejs:

ansible-playbook rollback.yml --extra-vars "MICROSERVICE_NAME=microservice-nodejs"

navigate to bash subfolder and execute the following bash scripts to do either:

./deploy-microservice-java.sh
./deploy-microservice-nodejs.sh

./rollback-microservice-java.sh
./rollback-microservice-nodejs.sh
