Terraform and Ansible

I have used terraform as an Infrastructure as code (IaC) tool to provision my infrasctructure on AWS. Provisioned infrastructure inlude; VPCs, EKS Clusters, Private and Public subnets, Iinternet Gateway, Routing Tables, SECURITY GROUP, etc. https://github.com/WinifredZenabuin/UnityProject/blob/master/CI-CD%20Intergration.JPG

EKS Getting Started Guide Configuration

This is the full configuration from https://www.terraform.io/docs/providers/aws/guides/eks-getting-started.html

See that guide for additional information.

NOTE: This full configuration utilizes the Terraform http provider to call out to icanhazip.com to determine your local workstation external IP for easily configuring EC2 Security Group access to the Kubernetes servers.

Provision EKS Infrastructure on AWS using Terraform

terraform init terraform plan terraform apply terraform destory

Jenkins

Jenkins will enable us to achieve Continuos Integration and Continuous Deployment. Our Jenkins pipeline-script will ensure once the application is developed or modified it is automatically build using maven, tested using selenium, validated using SonarQube. The build artifacts will be uploaded to Nexus Private aritifact repository.

GitHub

The scripts used for this project can be clone from https://github.com/WinifredZenabuin/UnityProject. I also confihured github-webhook so that ounce the source code is modified jenkins will srtigger a build.

Dockerfile

we are also using the created package (artifacts) to create a docker imgae for our application. Here docker is used for containerisation.

docker build -t legah2045/springboot-app .

Kubernetes Manifest files

This files will deploy a "Spring-boot-app" with a MongoDB. Our application and database is deployed using Replicat Set, ConFigMap, Ingress Controller, Secrets, PVC, StorageClass, HPA, and Cluster-Auto-Scaling. We have also deployed Grafana and Prometheus using Helm Charts. This will monitor our applications, send alerts and as such we are going to achieve high availability.

kubectl create deployment autoscaler-demo --image=nginx
kubectl get pods --all-namespaces | grep Running | wc -l
kubectl get nodes -o yaml | grep pods
kubectl scale deployment autoscaler-demo --replicas=20

Build Project Using Maven

Maven is java based build tool to generate executable

packages(jar, ear,war) for java based projects.

mvn clean package

Create Docker Image

Docker is a continerization tool.Using docker we can deploy our applications as

containers using docker images. Containers contains application code and also the softwares,

config files whatever is required for our application to run.

Create docker image using Dockerfile

docker build -t legah2045/springboot-app .

Deploy Application Using EKS Cluster

kubectl apply -f springboot-app-deployment.yml

List Docker Containers

docker ps -a
