jenkins-agent-manager (jam)

A simple service which manages Vagrant boxes based on the load of the Jenkins master and requested box.

Setup

• git clone https://github.com/mndfcked/jenkins-agent-manager.git into your $GOPATH/src directory.
• cd into the cloned folder, run go install and jenkins-agent-manager or go run *.go

Configuration

jam expects a JSON formatted configuration file. The default path is set to /etc/jenkins-agent-manager/config.json, but you can use the flag -confPath="/path/to/your/config/file.json" to pass a custom path to jam. The sample configuration below lists all currently available options.

{
  "jenkins_api_url":"http://localhost:8080",
  "jenkins_api_secret":"",
  "listener_port":"8888",
  "max_vm_count":2,
  "working_dir_path":"/tmp",
  "boxes":[
    {
      "name": "win7-slave",
      "labels": ["windows", "windows7"],
      "memory": "2048MB"    
    },
    {
     "name": "centos7-slave",
     "labels": ["linux", "centos7", "centos"],
     "memory": "2048MB"
    }  
  ]
}
