Spinnaker : Getting started guide — Part 3(Setting up Jenkins for building)

Now that we got Spinnaker up and running. Let’s see how we can launch an instance.

The recipe for launching an Instance in the cloud.

• Your business logic should be in a .deb ( or a debian )
• Business logic Example : Apache / nginx webserver, application server, a python script.
• Your debian + BaseAMI = your application.
• Packer : The tool we will use to achive the above ( Your Debian and BaseAMI = Your AMI).
• The AMI will be used to launch an instance.

Task # 1 : Install Jenkins

1. Launch an EC2 Debian instance
2. Update and install Jenkins

1. sudo apt update
2. sudo apt install openjdk-11-jdk
3. curl -fsSL https://pkg.jenkins.io/debian-stable/jenkins.io.key | sudo tee /usr/share/keyrings/jenkins-keyring.asc > /dev/null
4. echo deb [signed-by=/usr/share/keyrings/jenkins-keyring.asc] https://pkg.jenkins.io/debian-stable binary/ | sudo tee /etc/apt/sources.list.d/jenkins.list > /dev/null
5. sudo apt update
# If the above fails then run the following
# wget -q -O - https://pkg.jenkins.io/debian-stable/jenkins.io.key | sudo apt-key add -
# sudo sh -c 'echo deb https://pkg.jenkins.io/debian-stable binary/ > \
#e>     /etc/apt/sources.list.d/jenkins.list'
#  sudo apt-get update -y

6. sudo apt install jenkins
7. systemctl status jenkins
8. sudo apt install git

# Install deb-s3 which is used to upload files to S3
1. sudo apt install ruby
2. sudo apt install ruby-full 
3. sudo gem install pkgr deb-s3

# Login to Jenkins 
1. sudo cat /var/lib/jenkins/secrets/initialAdminPassword
2. You should be able to loing using the Admin Password 
3. Login URL = http://public_IP:8080

Task # 2 : Build your first Debian using Jenkins

Prerequisite : Create a public S3 bucket for hosting debian . This is for Spinnaker to pick them up when baking an AMI. An Artifactory is a place to store your debians.

Login to your Jenkins instance → Create job → “Freestyle Project” Perform the following,

• Under “Source Code Management”,
• Select : “Git”
• Provide the git URL : https://github.com/nagwww/adobe-deb.git
• Select the Branch as “Main:
• Under “Build Steps” select “Execute shell” , type in

./gradlew buildDeb
deb-s3 upload --bucket s3-bucket-for-artifactory --arch all --codename trusty --preserve-versions true build/distributions/*.deb

• Under “Post Build” select “Archive Artifacts”

build/distributions/*.deb

• Click on “Build Now” you should see your Debian created.

Task # 3 : Spinnaker to Jenkins Integration

Add the following to Spinnaker for integrating your Jenkins instance

      ci:
        jenkins:
          enabled: true
          masters:
          - name: jenkins-master-name
            address: http://44.203.77.241:8080/
            username: admin
            password: **************
            csrf: false

Task # 4 : Create the following pipelines to launc an EC2 instance

The main things to note are the following,

Template File Name : aws-ebs.json

repository : http://a-artifactory.s3-website-us-east-1.amazonaws.com trusty main
