In a Jenkinsfile:
node {
sh './packer build -color=false jenkins_agent_ami.json'
sh 'JENKINS_AUTH_USER="packer" JENKINS_AUTH_PASSWORD="SECRETPASSWORD" EC2_CLOUD_INSTANCE=ec2 AMI_PROFILE_NAME="aws-jenkins-agent" AWS_REGION="eu-west-1" python jenkins-update-ec2-ami.py'
}
EC2_CLOUD_INSTANCE is the name of the Amazong EC2 cloud in the plugin (as seen in the screenshot below).
AMI_PROFILE_NAME is the AMI’s “Description” in the EC2 plugin.
