VMagent

Summary

Create a VM image to be a buildkite agent that can be run on multiple platforms, set up a corresponding VirtualBox machine and export it to be a Vagrant box.

Requirements

• VirtualBox
• Python 2.7 (Haven't tested on Python 3 yet)
• Packer v1.0.4
• Vagrant v1.9.3
• Jinja2

Get started

Before running the program, you need to:

• Generate a service account key for your Google API credentials and name it google_credential.json to put into credentials/ directory.
• Have a buildkite-agent token to pass to the program

To see the usage of the program, you can type python vmagent.py -h in the terminal:

usage: vmagent.py [-h] --token TOKEN --vm_number VM_NUMBER [--name NAME]
                  [--memory MEMORY] [--cpus CPUS]

Setting up buildkite agents using Ubuntu Trusty virtual machines.

optional arguments:
  -h, --help            show this help message and exit
  --token TOKEN         Buildkite agent's token.
  --vm_number VM_NUMBER
                        Number of buildkite agents to set up.
  --name NAME           Name of the vagrant box.
  --memory MEMORY       Memory of each buildkite agent VM (in megabytes).
  --cpus CPUS           Number of cpus for each buildkite agent VM.

To run the program, please type:

python vmagent.py --token <buildkite_agent_token> --vm_number <number_of_vms_to_setup>

You can also add options such as memory and cpus to configure the memory and number of cpus used in the virtual machines.

After this command you will have a Vagrant box in the output/ folder, which is also already added to your Vagrant, and a Vagrantfile in the current directory. You can change the configurations in Vagrantfile and simply do vagrant up to run the virtual machines.

After you do vagrant up, the virtual machines will start running, and buildkite agents on these machines will be started as well.
