How To Setup Jenkins in Docker

My next few blogs will be related to Jenkins, Docker and Kubernetes .

FYI, Same tutorial is available in youtube.

What’s Jenkins? Jenkins is a automation tool which you can create jobs to build, test and deploy your application.

Jenkins + Docker

You can create your pipelines in Jenkins. But whats’s pipeline? Pipeline is a script which executes step by step of all things you need to do. Example: you will create a pipeline to build your code. First step is to checkout your git code, after this you need to test, build, package, create a docker image and finally, deploy your code.

For first step with Jenkins, let’s create a container in your machine.

You need Docker installed and running in your machine.

Execute this command:

docker run -p 8080:8080 -p 50000:50000 jenkins

This command will download and run a Jenkins in your machine.

Wait for some time,when Jenkins was initialized, the console will show you a admin password to start Jenkins initial setup. The text with password is:

*************************************

Jenkins initial setup is required. An admin user has been created and a password generated.
Please use the following password to proceed to installation:

b9ad7c6d6b894ba89d7b8d******

This may also be found at: /var/jenkins_home/secrets/initialAdminPassword

**************************************

You can access your Jenkins in http://localhost:8080/. You will see this screen and provide the initialAdminPassword to continue:

Unlock Jenkins

In next screen, click “Install suggested plugins”

Customize Jenkins

Wait for the plugins installations

Getting Started

Now, create a first admin user by providing the username and password.
