| To create a fresh builder host: (should only be needed once) |
| |
| Create a new Scaleway server with type "Docker 1.5" (second tab). |
| |
| Make a tmpfs: |
| # echo "tmpfs /tmpfs tmpfs" >> /etc/fstab |
| # mkdir /tmpfs |
| |
| Make a 2GB swap file: |
| # dd if=/dev/zero of=/swap count=2097152 obs=1024 |
| # mkswap /swap |
| # chmod 0600 /swap |
| # echo "/swap none swap loop 0 0" >> /etc/fstab |
| |
| Reboot. |
| |
| Should see swaps in "cat /proc/swaps" and tmpfs in "cat /proc/mounts" now. |
| |
| * Copy the contents of this directory to the server. |
| |
| * Go into that directory and: |
| # docker build -t buildlet . |
| |
| Add to /etc/rc.local: |
| |
| (mkdir -p /tmpfs/buildertmp && docker run -e BUILDKEY_ARM=xxx -e BUILDKEY_ARM5=xxx -v=/tmpfs/buildertmp:/tmp --restart=always -d --name=buildlet buildlet) & |
| sleep 5 |
| |
| .. before the exit 0 |
| |
| Power it down (with ARCHIVE), |
| |
| Snapshot the disk. |
| |
| Start a bunch of them. (see golang.org/x/build/cmd/scaleway) |
