How to use node-ssh (or ssh2) with TeamCity's ssh-agent

ssh.md

This is actually really straight forward, just use the SSH_AUTH_SOCK environment variable:

const socket = process.env.SSH_AUTH_SOCK
const ssh = new (require('node-ssh'))

ssh.connect({
  username: 'username',
  host: 'example.com',
  agent: socket
}).then(() => {
  // success
}, console.error)
