Demonstration of SpringBoot web application deployment to Kubernetes cluster at AWS using Jenkins

Overview:

Script DevOps028.Demo4/kubernetes/create_clusters.sh will:

create Kubernetes cluster at AWS and deploy to it:
- preconfigured Jenkins with pipeline job to build and deploy web application
- private Registry to store Docker images
build all necessary Docker images for Jenkins and push it to private Registry
create Kubernetes cluster at AWS for SpringBoot web application
set alias DNS records at AWS for loadbalancers with:
- Jenkins
- Registry
- Web application Samsara

After running this script you will be able to visit Jenkins site and run preconfigured job to build and deploy web application

Prerequisites:

This tools should be installed before running deployment scripts:

kops
kubectl

Also you should have registered domain name, e.g. example.com, and SSL certificate (private key and certificate files) for domain registry.example.com

Registry also requires password authentification to be set. Please read this official guideline about restricting access to Registry

You can change these variables and path to certificate files in bash script DevOps028.Demo4/kubernetes/create_clusters.sh

Please follow this official guideline about prerequisites for Kubernetes cluster creation at AWS.

Deployment steps:

Clone this git repository
Export environment variables AWS_DEFAULT_REGION, AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY
Run script DevOps028.Demo4/kubernetes/create_clusters.sh
Open Jenkins website, e.g. http://jenkins.lerkasan.de:8080
Run pipeline job called Demo4
You also may explore Regitry with docker images https://registry.lerkasan.de
Wait for Jenkins to finish executing pipeline job
Visit Samsara application website http://samsara.lerkasan.de
