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

Machines:

golang-builder-1:

     $ ssh -i ~/keys/id_ed25519_golang1 root@147.75.92.14
     (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

But each machine is setup like:

   # local
   $ scp -i ~/keys/id_ed25519_golang1 -r .. root@147.75.92.14:~

   # on packet box
   $ apt-get install docker.io

   $ build.sh (with Dockerfile in same directory)

   $ echo "<BUILDER KEY>" > /etc/gobuild.key
   
   # local 
   $ GOARCH=arm64 GOOS=linux CGO_ENABLED=0 go install golang.org/x/build/cmd/rundockerbuildlet && \
     scp -i ~/keys/id_ed25519_golang1 ~/bin/linux_arm64/rundockerbuildlet root@147.75.92.14:/usr/local/bin

   # on packet box
   $ scp -i ~/keys/id_ed25519_golang1 rundockerbuildlet.service root@147.75.92.14:/etc/systemd/user/

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