Integrating Github , Jenkins and Docker (running a container in docker)

JENKINS / DOCKER / GITHUB

This article contains how Jenkins makes the project automate for the developer from writing the code to deployment just by assigning the jobs.

Task :-

• Use the docker file to build the container with the customized image having Jenkins installed .
• Jenkins should automatically Start as soon as the image is successfully launched.
• Now we have assign the jobs to the Jenkins and create a chain of the jobs using pipeline plugins.

Now, we are going to create the file with name DOCKERFILE having the following commands:

DOCKERFILE

Now we will use our VM and run the command :

DOCKER FILE USING CLI

Jenkins project performs a full test flow with the following JDK/JREs:

OpenJDK JDK / JRE 8 - 64 bits

OpenJDK JDK / JRE 11 - 64 bits

Using the cmd : docker image

To check the status that the image is active or not

Now , logging in Jenkins in browser

LOGIN USING USERNAME AND PASSWORD

JOB 1:- Automatically pulling the repo from GitHub whenever the developer push the repo using ssh plugins.

> After successfully logging in to jenkins we have to install GitHub plugin .

> Then we have to provide the GitHub URL to fetch data.

JOB2:- By looking at the code or program file , jenkins should automatically start the respective language interpreter install image container to deploy code.

USING THIS CODE JENKINS INSTALL THE CONTAINER TO DEPLOY THE CODE OF DEVELOPER

JOB3:- Testing the app if it is working or not .

JOB4:- Check if the app is not working , then send email to developer with error messages.We created a python file and if this site wont work or face any error ,it will run and developer will receive any email.

>import smtplib

>server = smtplib.SMTP_SSL(“smtp.gmail.com”,465)

>server.login = (mltask2@gmail.com,******)

>server.sendmail(“rohitkumawat1968@gmail.com”,

your site is not working)

>server.quit()

This is the full automation of the php server using GitHub, Jenkins, and Docker.

Thank u…!!
