Install Jenkins, configure Docker as agent, set up cicd, deploy applications to k8s and much more.

## AWS EC2 Instance

- Go to AWS Console

- Instances(running)

- Launch instances



### Install Jenkins.

Pre-Requisites:

 - Java (JDK)

### Run the below commands to install Java and Jenkins

Install Java

```

sudo apt update

sudo apt install openjdk-17-jre

```

Verify Java is Installed

```

java -version

```

Now, you can proceed with installing Jenkins

```

curl -fsSL https://pkg.jenkins.io/debian/jenkins.io-2023.key | sudo tee \

  /usr/share/keyrings/jenkins-keyring.asc > /dev/null

echo deb [signed-by=/usr/share/keyrings/jenkins-keyring.asc] \

  https://pkg.jenkins.io/debian binary/ | sudo tee \

  /etc/apt/sources.list.d/jenkins.list > /dev/null

sudo apt-get update

sudo apt-get install jenkins

```

**Note: ** By default, Jenkins will not be accessible to the external world due to the inbound traffic restriction by AWS. Open port 8080 in the inbound traffic rules as show below.

- EC2 > Instances > Click on 

- In the bottom tabs -> Click on Security

- Security groups

- Add inbound traffic rules as shown in the image (you can just allow TCP 8080 as well, in my case, I allowed `All traffic`).



### Login to Jenkins using the below URL:

http://:8080    [You can get the ec2-instance-public-ip-address from your AWS EC2 console page]

Note: If you are not interested in allowing `All Traffic` to your EC2 instance

      1. Delete the inbound traffic rule for your instance

      2. Edit the inbound traffic rule to only allow custom TCP port `8080`

  

After you login to Jenkins, 

      - Run the command to copy the Jenkins Admin Password - `sudo cat /var/lib/jenkins/secrets/initialAdminPassword`

      - Enter the Administrator password

      



### Click on Install suggested plugins



Wait for the Jenkins to Install suggested plugins



Create First Admin User or Skip the step [If you want to use this Jenkins instance for future use-cases as well, better to create admin user]



Jenkins Installation is Successful. You can now starting using the Jenkins 



## Install the Docker Pipeline plugin in Jenkins:

   - Log in to Jenkins.

   - Go to Manage Jenkins > Manage Plugins.

   - In the Available tab, search for "Docker Pipeline".

   - Select the plugin and click the Install button.

   - Restart Jenkins after the plugin is installed.

   



Wait for the Jenkins to be restarted.

## Docker Slave Configuration

Run the below command to Install Docker

```

sudo apt update

sudo apt install docker.io

```

 

### Grant Jenkins user and Ubuntu user permission to docker deamon.

```

sudo su - 

usermod -aG docker jenkins

usermod -aG docker ubuntu

systemctl restart docker

```

Once you are done with the above steps, it is better to restart Jenkins.

```

http://:8080/restart

```

The docker agent configuration is now successful.
