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-5.0.0 -b release-5.0.0
   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-5.0.0/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)
