Jenkins Freestyle Project for DevOps Engineers

What is CI/CD?

CICD Pipelines i.e Continuous Integration, Continuous Delivery and Deployment pipelines, are a way of running Jenkins jobs in a sequence, which resembles a pipeline view.

What are CI/CD Pipelines?

What Is a Build Job?

A Jenkins build job contains the configuration for automating a specific task or step in the application building process. These tasks include gathering dependencies, compiling, archiving, or transforming code, and testing and deploying code in different environments.

Jenkins supports several types of build jobs, such as freestyle projects, pipelines, multi-configuration projects, folders, multibranch pipelines, and organization folders.

What is Freestyle Projects ??

Jenkins freestyle projects allow users to automate simple jobs, such as running tests, creating and packaging applications, producing reports, or executing commands. Freestyle projects are repeatable and contain both build steps and post-build actions.

Task 1:-React Django App

In This Task, we are using React Django App

Step 1:- First we need to create a new item

Step 2:- Now need to give the project name and choose Freestyle project and click on ok

Step 3:- After clicking ok , Need to give the Description and check the GitHub project and need to give GitHub project URL

Step 4:- In Source Code Management choose Git and need to provide the git hub URL and Branch Specifier section, since in the GitHub the code is the main branch so we have to specify the same name

Step 5:- In the Build Step tab, select "Execute Shell" and pass the docker build command Next, pass the docker run command to start a container using the image specified.

echo " $USER Hello i have started my devps journey"

echo "i will build the code using docker"
docker build . -t rect-django-app
echo "i will perfom the test if required"

echo "i will deploy code"
docker run -itd -p 8001:8001 rect-django-app:latest

Step 6:- Now before running the build now we have to make sure that the below commands are installed in the Ubuntu machine

#Below command use to install docker in ubuntu machine
sudo apt-get install docker.io -y
#Below command use to add docker user
sudo usermod -aG docker $USER
#Below command use for rebbot machine
sudo reboot

Step 7:- Now we need to run the Build now

Step 8:- Once the build is successful, you can go to the console output and check the output of the build.

Step 9:- Now we need to verify whether we can browse the application or not by using Public IPv4 address:prot_number

TASK 2:-

• Create a Jenkins project to run the "docker-compose up -d" command to start the multiple containers defined in the compose file

• Set up a cleanup step in the Jenkins project to run "docker-compose down" command to stop and remove the containers defined in the compose file.

Step 1:- Before running the "docker-compose up -d" file we need to install docker-:- compose in the Ubuntu machine

Step 2:- now need to give the docker-compose command and save and then click on build now

Step 3:- in the console output we can check the output

Step 4:- Now we need to verify whether we can browse the application or not by using Public IPv4 address:prot_number
