DevOps-Project-3-tier-Application-Deployment-Azure

For your reference the Source Code for this project is present in the GitHub Repository https://github.com/singhritesh85/TWSThreeTierAppChallenge.git inside the directory Application-Code. However for the current project I have used Azure Repos into which the source code is present. as shown in the screenshot below.

1. This is a three tier application (of Things-to-Do App) in which frontend or presentation layer is React Js code which is present in the directory Application-Code/frontend in the GitHub Repo https://github.com/singhritesh85/TWSThreeTierAppChallenge.git. To deploy React Js code I have created a Pipeline using Azure DevOps.
2. The Backend or Application layer is Node Js code which present in the directory Application-Code/backend in the GitHub Repo https://github.com/singhritesh85/TWSThreeTierAppChallenge.git. To deploy Node Js code I have created a Pipeline using Azure DevOps.
3. For Database or Data layer MongoDB has been used. To deploy MongoDB I have created a Pipeline using Azure DevOps.
4. To Deploy the three Pipelines I have used Helm and helm chart. These helm charts are present in the GitHub Repo https://github.com/singhritesh85/helm-repo-for-ArgoCD-three-tier-app-backend.git, https://github.com/singhritesh85/helm-repo-for-ArgoCD-three-tier-app-frontend.git and https://github.com/singhritesh85/helm-repo-for-ArgoCD-three-tier-app-database.git. In the current project I have clonned the helm chart from above mentioned repositories inside the home directory of user which is /home/demo.
   
   As discussed above there are three Pipelines using which ReactJs code, NodeJs code and MongoDB have been deployed. which is also shown in the Architechture diagram above. The azure-pipelines.yaml for ReactJs Code, NodeJs Code and MongoDB is present inside the directory azure-pipelines in this Repository. Before Running Jenkins Job for MongoDB create the password, pv (persistent volume) and pvc (persistent volume claim). To do so run the command kubectl apply -f pv.yaml, kubectl apply -f pvc.yaml and kubectl apply -f secrets.yaml. The password for MongoDB is encrypted with base64.
   
   

Encryption with Base64
==================================
echo "admin"|base64 -----------> Encrypt the username
ehco "password123"|base64  --------------> Encrypt the password


Decryption with Base64
==================================
echo "YWRtaW4="|base64 --decode
echo "cGFzc3dvcmQxMjM="|base64 --decode

The screenshot for SonarQube Analysis is shown below.

To keep the Docker Images for frontend and backend I have created two container registries with the name of akscontainer24registry1 and akscontainer24registry2 respectively in Azure Container Registries (ACR) as shown in the screenshot below. After Successfully Running the three Pipelines (successfully deployment of the three-tier Application) create the URL for the application using the file ingress-rule.yaml present inside the directory ingress-rule-pv-pvc-mongodbsecret with the command kubectl apply -f ingress-rule.yaml. Create a record set for the URL inside the hosted zone as shown in the screenshot below.

Using the created URL backend.singhritesh85.com access the application as shown in the screenshot below.

After Successful deployment we can see the Applications using command line as shown in the screenshot below.

The Service Connection is created as shown in the screenshot below.

The three pipelines in Azure DevOps is as shown in the screenshot below.

The frontend-auth and backend-auth secrets for kubernetes can be created using the command below

kubectl create secret docker-registry frontend-auth --docker-server=https://akscontainer24registry2.azurecr.io --docker-username=akscontainer24registry2 --docker-password=XXXXXXXXXXXXXXXXXXXXXXXXXXXOJ7eXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXFyh6 -n three-tier


kubectl create secret docker-registry backend-auth --docker-server=https://akscontainer24registry1.azurecr.io --docker-username=akscontainer24registry1 --docker-password=XXXXXXXXXXXXXXXXXXXXXXXXXXXX4rHeWXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX1skn -n three-tier
