Steps for End to End Pipeline Automation

Pre-requisite :

1. JDK1.8 or +
2. Eclipse Neon or +
3. Maven 3.3 or +
4. Jenkins latest

1. Create an Spring Boot Application

Follow the instructions at below link to create an Spring Boot Application.

https://github.com/shubhamkushwah123/DevOps_README/blob/master/README_SpringBoot.md

2. Build and Test the Application using MAVEN.

1. Open the Command Prompt and check maven installation.

mvn --version

2. Navigate to the project folder, where pom.xml resides and run below command to build the application.

mvn clean test install

3. Upload the Code to the GitHub Repository.

1. Create an account on https://www.github.com

2. Login to the Account.

3. Create a public repository.

4. Copy the repository url to clone. (e.g. It looks like this : https://github.com/shubhamkushwah123/DevOps.git)

5. Open command prompt in your machine and navigate to the project folder, where pom.xml resides.

6. Initializes the local git repository. (Inside the project folder, run below command)

git init

git config --global user.name = "your name"

git config --global user.email - "your email address that you have used to login to github"

git add .

git remote add origion <the git repository url that you have copied into the above steps>
git remote add origin https://github.com/shubhamkushwah123/DevOps.git

git push origin master

Note : Check the repository in github.com, Your application code should be there in your github repository.

4. Creating Jenkins Pipeline.

1. To Launch the Jenkins, Go to the folder, where jenkins.war is placed and run below command.
