Only needed to create new machines: (skip this step)

  p: see link in email (l:password packet)

Machines:

golang-builder-1:

     $ ssh -i ~/keys/id_ed25519_golang1 root@147.75.109.230
     (key: http://go/golang-ssh-key)

Machine details:

  root@golang-builder-1:~# cat /proc/cpuinfo | grep process | wc -l
  96
 
  root@golang-builder-1:~# free
  total        used        free      shared  buff/cache   available

  root@golang-builder-1:~# lsb_release  -a
  No LSB modules are available.
  Distributor ID:    Ubuntu

  Codename:          xenial


But each machine is setup like:

   $ apt-get install docker.io
   
   $ build.sh (with Dockerfile in same directory)
   
   $ GOARCH=arm64 GOOS=linux go install golang.org/x/build/cmd/rundockerbuildlet && \
     scp -i ~/keys/id_ed25519_golang1 ~/bin/linux_arm64/rundockerbuildlet  root@147.75.109.230:/usr/local/bin

   $ scp -i ~/keys/id_ed25519_golang1 rundockerbuildlet.service root@147.75.109.230:/etc/systemd/user/

   $ systemctl enable /etc/systemd/user/rundockerbuildlet.service
   $ systemctl start rundockerbuildlet.service
