How to Install Jenkins

Jenkins is an open-source Java application server for Continuous Integration and Continuous Delivery (CI/CD). This will run in servlet containers such as Apache Tomcat. It helps the developers to build, test, and deploy the software by automating using CI/CD pipelines. It detects bugs and notifies the developers in an early stage.


How to Download and Install:

Step 1: Go to https://www.jenkins.io/. Click Download

Step 2: Download Jenkins ‘Generic Java package’. I prefer to download the LTS package (It is a stable one).

Step 3: Select your desired path after downloading and save the Jenkins.war file in your local system.

Step 4: Go to command prompt (Windows) | Terminal (IOS)

               Go to the folder where the war file is saved. Then, type the command java -jar Jenkins.war and run it. It will take a while to run the command. It gives an admin password. Note it down to use Jenkins the first time. The password will be saved in the Jenkin path.

Step 5: Go to the browser and type http://localhost:8080/ and enter. It asks for the password. Provide it and click Continue.

Step 6: Select Plugins to install.

Step 7: Select the plugins and click Install.

Step 8: After installing, it goes to the page that asks for credentials to create. You can select an admin user to proceed if you do not want to create a new id.

Step 9: Click Save and Finish.

Step 10: Your Jenkins is ready now and start using Jenkins.

Step 11: Now, you will land on the Jenkins homepage after installing it.

Step 12: All the Jenkin-related plugins and folders will be in the available path.


Now, you are ready to go for automating the process of CI/CD pipelines.

HTTP Payloads

 What happens when I send a letter without information to the receiver that I require some details from them? What happens when the receiver writes a response to my letter without having the information I need? This information is similar to the body generally called a payload in HTTP request and response.  Let us see the payload in the HTTP request and HTTP response individually. I have added the below image to explain the HTTP request and response body/payload in JSON. I have used BurpSuite to take this image and Swagger Petstore (petstore.swagger.io) for this example. HTTP Request Payload Generally, the payload is not required for all the requests and responses. GET and HEAD methods usually do not require a body while sending a request to the server. The above example is a POST request to create a resource name 'doggie'. To achieve this, I should send some information about the resource which is called HTTP request payload. Breakdown of request payload: Content-Type:  Specif

Variables in Postman

What is a variable? This is the basic question to learn when you start programming. I am not going to dive deep into the programming concepts. Let me explain the variables used in Postman. What is a Variable in Postman? A data unit, that stores a value and it is dynamic based on the data type we use.  Should be written as Key: Value pair (Example: name= "Test"; num=1;) Provides the facility to access the value without manual effort every time. There are 5 different scopes of variables used in Postman. Global Variables Environment Variables Collection Variables Data Variables Local Variables These variable scopes are specially designed to refer to values in the Postman tool. Global Variable:          When the variable is assigned globally, it has all the privileges of accessing anywhere in the workspace such as the Environment, Collection. Environment Variable:          It is limited within the specific environment where you can access data between collections. Collection Vari
