Steps to be followed:

• 1. Set up ELK stack on Docker
• 2. Configure Jenkins pipeline for Docker build and deployment
• 3. Run the Spring Boot application and check the logs in Kibana

sudo su
git clone https://github.com/manikcloud/elk-stack.git
cd elk-stack
ls -alrt

apt install docker-compose
docker-compose version

sudo sysctl -w vm.max_map_count=262144

docker-compose up -d
docker ps

http://localhost:5601/app/kibana

• Notedown your user name.
• 1. Goto the Jenkins file.
• 2. Replace your docker hub username from varunmanik in line no. 3.
• 3. run this command

 git add . && git commit -am"adding dockerhub user name in jenkins file " && git push 

• Install Docker pipeline plugin in jenkins
• http://localhost:8080/pluginManager/

• 2.1 From the browser, navigate to http://localhost:8080 and login to Jenkins.
• 2.2 Configure your Docker hub credentials in Jenkins. Go to Manage Jenkins -> Manage Credentials -> click on Jenkins link -> click on Global credentials (unrestricted) -> click on Add Credentials from the left pane.
• http://localhost:8080/credentials/store/system/domain/_/newCredentials

Username: <Your_DockerHub_Username> Password: <Your_DockerHub_Password>

• 2.4 You should now see the credentials saved as shown below

• 2.5 Create a Jenkins pipeline job to fetch Jenkinsfile from the URL mentioned below.

• 2.6 You can either use the below git repository or Fork it in your Github account and use it https://github.com/manikcloud/elk-stack.git

• 2.7 Configure the job as shown in the screenshot below and then run the build.

• 2.8 Give 777 permission to the Docker sock file since we are running Docker command from a Jenkins user.

chmod 777 /var/run/docker.sock

• 2.9 Build the Jenkins job to deploy the Docker container on the Docker host.

• 2.10 Jenkins pipeline will complete the build and the deployment process for the Spring Boot application

• 2.11 We can see the Docker container deployed on the Docker host using the command:

docker ps | grep springbootapp

• 3.1 Access the Spring Boot web application and perform some random activity so that the logs will be pushed to ELK stack.

http://localhost:81

• 3.2 Check the logs pushed to ELK stack in Kibana.

• 3.3 Navigate to the Kibana dashboard. Select Management > Index Management from the navigation bar on the left. You can see the logs created.
