ZeroTier GitHub Action

ZeroTier is an SDN platform that allows users to create virtual networks that can span multiple devices, locations, and cloud providers. ZeroTier creates an encrypted peer-to-peer mesh overlay network that handles NAT traversal and authentication to network resources.

The ZeroTier Github Action allows users to easily integrate ZeroTier into their CI/CD workflows by temporarily joining and authorizing runners onto private ZeroTier networks.

- name: ZeroTier
  uses: zerotier/github-action@v1.0.1
  with:
    network_id: ${{ secrets.ZEROTIER_NETWORK_ID }}
    auth_token: ${{ secrets.ZEROTIER_CENTRAL_TOKEN }}

ZEROTIER_CENTRAL_TOKEN can be provisioned from Account section in the ZeroTier Central admin panel.

This Action works on Ubuntu, MacOS, and Windows runners.

---

This action installs ZeroTier on the runner node and generates a unique ZeroTier identity.
It then uses the supplied auth_token to authorize the runner onto the network.

- name: ZeroTier
  uses: zerotier/github-action@v1.0.1
  with:
    network_id: ${{ secrets.ZEROTIER_NETWORK_ID }}
    auth_token: ${{ secrets.ZEROTIER_CENTRAL_TOKEN }}
    
- name: ping host
  shell: bash
  run: |
    count=10
    while ! ping -c 1 ${{ secrets.ZEROTIER_HOST_IP }} ; do
      echo "waiting..." ;
      sleep 1 ;
      let count=count-1
    done
    echo "ping success"

After the workflow has completed, a post step automatically cleans up by removing the runner from the network.
