STEPS FOLLOWED FOR THE ENTIRE CICD PIPELINE SETUP

1) Created two github repositories.

One repository to store the code and another repository to store the manifest files . The manifest repo is a private repository .

2) Started a Jenkins server at port 8080 and installed some plugins .

3) Started a sonarqube server at port 9000 .

4) Created a token on Sonarqube server ( at adminstration > security > users ).

5) Configure sonarqube server on Jenkins .

Here mentioned the sonarqube server URL and also created a secret text using the token ( created in step 4 ) and added that secret text into the sonarqube server .

6) Setup Sonarqube scanner on Jenkins .

Here in tools section of manage Jenkins i have configured the sonarqube scanner . Just given the desired version of sonarqube scanner and a name to the scanner .

7) Setup Quality gate on sonarqube .

On Sonarqube server , at adminstration ? configuration > webhook , added the <jenkins_url>/sonarqube_webhook and a name .

8) Configure gmail and jenkins integration .

Here i have first created an app password on gmail .

Then using the app password , created a username and password credential on Jenkins .

Then on system of manage jenkins configured the gmail . Here i have mentioned the smtp server and its port as 465 .

9) Integrated dockerhub and Jenkins .

Here created a username and password credential on the Jenkins server . Here i have mentioned my dockerhub account username and the password . Here the username and password can be accessed by using the ID .

10) Integrated Github and Jenkins .

Here first created a personal token on github .

Then created a secret text credential by using the github personal token on Jenkins .

11) Created a K8s cluster using Kind .

kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
- role: control-plane
  extraPortMappings:
  - containerPort: 32215
    hostPort: 80
  - containerPort: 32216
    hostPort: 8081
- role: worker

12) ArgoCD setup using the private manifest repository .

Here first created argocd namespace .

Then generated the argocd server password .

Then port forward the argocd server access to port 8078 .

After connecting the argocd server , i have first updated the argocd password .

Then connected the manifest repo file using the github manifest repo url , github username and github personal token .

Created an application from the connected github repo .

After this argocd started deploying the manifest files .

13) Written the Jenkins pipeline code .

14) Started prometheus at port 9090, grafana at port 3000 and blackbox exporter at port 9115 .

Here i have configured the prometheus.yml inside the prometheus container . Here added the some code which will help to scrape the metrics from the blacbox exported and Jenkins .

Then restarted my prometheus container . After this checked the targets in prometheus server .

Then integrated prometheus and grafana .

15) Now started the my Jenkins pipeline .

It will build the version 1 of my website .

Jenkins Pipeline result:

Sonarqube result :

Argo CD deploys the version 1 of website :

Received the trivy reports and pipeline status on my gmail .

16) Updated the code .

Now the website of version 2 .

Jenkins Pipeline result after website code is updated to version 2 :

Argo CD automatically deploys the version of website .

Received status of pipeline on gmail:

17) Accessed the version 2 of website .

---ALL STEPS COMPLETED----

Manifest files

Here kubernetes secrets is used to store the API_TOKEN . Application runs at port 80 and it is connected to the backend at port 8081 .

Received which stages are failed on gmail while running a demo pipeline .

Monitoring results :

Blackbox exporter :
