Jenkins Setup

Jenkins is used to build, deploy and setup the infrastructure for Sunbird. Almost everything in Sunbird is automated using Jenkins pipelines which integrates with ansible and other tools.

• SSH to the Jenkins server and enter the following commands -

     git clone https://github.com/project-sunbird/sunbird-devops.git
     cd sunbird-devops && git checkout tags/release-4.10.0 -b release-4.10.0
     cd deploy/jenkins
     sudo bash jenkins-server-setup.sh

• Open Jenkins UI in a browser by visiting JENKINS_IP:8080

• Enter the initial password and follow the on-screen instructions. Choose Install suggested plugin and create an admin user

• Go to http://JENKINS_IP:8080/pluginManager/available -> Search for ‘Configuration as Code Plugin’ and install the plugin without restart.

Don’t run the following until above steps finished

• Run the below commands on Jenkins server -

    sudo bash jenkins-plugins-setup.sh
    cp envOrder.txt.sample envOrder.txt
    vi envOrder.txt

• Update the environment list as per your requirement in ascending order. For example, if you want to have dev, staging and production environments, your envOrder.txt will look like -

    dev=0
    staging=1
    production=2

• Run the below script on Jenkins server and provide input as required (case sensitive) -

    sudo bash jenkins-jobs-setup.sh

• Restart jenkins

    sudo service jenkins restart

• Configure Jenkins

  sudo su jenkins
  curl -SsL -o ~/jenkins.yaml https://raw.githubusercontent.com/project-sunbird/sunbird-devops/release-4.10.0/deploy/jenkins/jenkins.yaml
    
  # Replace all placeholders ${VALUE} with proper values
  # For example, 
  # username: "${GH_USERNAME}" to  username: "mygithubusername"
  vim ~/jenkins.yaml

• Run the below commands on Jenkins server -

    mkdir -p /var/lib/jenkins/secrets
    cd /var/lib/jenkins/secrets
    touch deployer_ssh_key vault-pass k8s.yaml
    chmod 600 deployer_ssh_key vault-pass k8s.yaml

• Copy the contents of your server’s private key into /var/lib/jenkins/secrets/deployer_ssh_key

• Copy the kubernetes config file contents into /var/lib/jenkins/secrets/k8s.yaml

• If you have encrypted your secrets.yml using ansible-vault, enter the password to decrypt into /var/lib/jenkins/secrets/vault-pass. If you have not encrypted, then enter a random value like 12345

• Run sudo visudo on jenkins server and add the below line -

      jenkins ALL=(ALL) NOPASSWD:ALL

• Reboot the Jenkins VM (sudo reboot)
