Step 1: Uploaded project dependencies to GitHub.

Step 2: In AWS, created an EC2 instance with ubuntu image and created a new key pair, allowed HTTP traffic.

Step 3: Connected to instance via EC2 instance connect.

Step 4: Installing Jenkins

     *Step 1*: Updating packages - *sudo apt update*
     *Step 2*: Installing Java - `sudo apt install openjdk-11-jre`  
     *Step 3*: Validating Java version by `java -version`.
     *Step 4*: Copying jenkins GPG keys.
     *Step 5*:  Updating packages `sudo apt update`.
     *Step 6*:  Installing Jenkins `sudo apt-get install jenkins`.
     *Step 7*: Starting jenkins sudo systemctl start jenkins
     *Step 8*: Validating Jenkins has started sudo systemctl status jenkins
     *Step 9*: Updating inbound rules to allow port 8080 from my Ip in security groups.
     *Step 10*: Opening Jenkins in localhost 8080.
    *Step 11*:  Unlocking Jenkins `/var/lib/jenkins/secrets/initialAdminPassword`.
    *Step 12*: Installing Plugins
    *Step 13*: Credentials and creating admin user.  (ubuntu, 1919)

Step 5: Creating a free style project.

Step 6: Configuring free style project.

    *Step 1*:  Specify Git hub project url.
    *Step 2*: Specify GitHub repository link in Source Code Management.
    *Step 3*:  Generating Key pair in EC2 instance `ssh-keygen`.
    *Step 4*: `cd .ssh`.
    *Step 5*: `cat id_rsa.pub`. 
    *Step 6*: Copying public key and pasting it in github settings/ssh and gpg keys.
    *Step 7*: In source code management specify credentials.
                credentials type: ssh
                id: github-jenkins
                username: ubuntu
                private key: in EC2 `cd .ssh/ cat id_rsa`. copy private key and paste it then click on add button.
                Now in credentials select ubuntu from list.
                Specify the branch from where jenkins need to import code.
    *Step 8*: Save and Build now and view Console ouput if any error occurs.
    *Step 9*: Navigating to workspace created by jenkins in EC2, path specified in console output.

Step 7: Installing Node js sudo apt install nodejs.

Step 8: Installing NPM sudo apt install npm.

Step 9: Validating installation by checking versions node -v npm -v.

Step 9: Installing packages specified in package.json using sudo npm install

Step 10: Starting web app using node filename.js and then edit inbound rules in ec2 security group and add port in inbound rules then open port with ec2 ip address.

Step 11: Installing Docker sudo apt install docker.io.

Step 12: Creating and writing Dockerfile.

Step 13: Building docker image docker build -t movie-info . .

Step 14: Building docker container docker run -d --name movie-info-web -p 3000:3000.

Step 15: Killed the container with docker kill <container id>.

Step 16: In Previously created jenkins free style job, configured and added a build step; execute shell and added docker commands for creating a image and running the image in docker container.

Step 17: Added plugin GitHub Integration in jenkins.

Step 18: In repository settings added a webhook with jenkins payload url and change the content type to application/json. http://<ip address>:8080/github-webhook/ .``

Step 19: Changed EC2 inboud rule settings port 8080 to anywhere IPv4 for git to access jenkins.

Step 20: In Previously created jenkins free style job, configure and enable GitHub hook trigger for GITScm polling in build triggers.
