Jenkins continuous deployment project

->This project will trigger any changes in the code in GitHub and trigger those changes using GitHub webhook to Jenkins where a job is created to build and run the code using docker-compose and deploy on ec2 instance.

• -> First, create a job, and fill in the details.

• Project URL:https://github.com/ManishNegi963/node-todo-cicd

• Source code management

Repository URL: https://github.com/ManishNegi963/node-todo-cicd.git

Branch: master

• Build Triggers

GitHub hook trigger for GITScm polling: It will constantly poll to the webhook (URL) created in the GitHub for any change and if any changes it will trigger a new build.

• Create a webhook in GitHub.

Committed Jenkins is amazing

• ->This will trigger a build as there is a push event(commit) in the master branch and it will automatically start the build.

• ->Go to the browser and paste the IP address with port 8000, code changes have been deployed automatically.
