Amazon EC2 (Ubuntu)

Here's an example session. This could definitely be improved and automated.

Dependencies (as root)

apt-get update
apt-get upgrade -y
apt-get install git awscli nginx

# Install Docker CE
# Configure apt-get per instructions
# https://docs.docker.com/engine/installation/linux/docker-ce/ubuntu/
apt-get install docker-ce

# Use a production-quality storage driver that doesn't leak disk space
cat >>/etc/docker/daemon.json <<EOF
{
    "storage-driver": "overlay2"
}
EOF

# Ensure Docker can control the PID limit
mount | grep cgroup/pids

# Ensure Docker can control swap limit
# https://docs.docker.com/engine/installation/linux/linux-postinstall/#your-kernel-does-not-support-cgroup-swap-limit-capabilities

service docker restart
usermod -a -G docker ubuntu # user needs to log out and in again

fallocate -l 1G /swap.fs
chmod 0600 /swap.fs
mkswap /swap.fs

Set aside disk space (as root)

fallocate -l 512M /playground.fs
device=$(losetup -f --show /playground.fs)
mkfs -t ext3 -m 1 -v $device
mkdir /mnt/playground

Configure disk mountpoints (as root)

cat >>/etc/fstab <<EOF
/swap.fs        none            swap   sw       0   0
/playground.fs /mnt/playground  ext3   loop     0   0
EOF

Reboot the instance at this point.

Get the code

git clone https://github.com/rust-lang/rust-playground.git
cd rust-playground

Set a crontab to update the assets, binary, and docker containers

crontab -e

Review the example crontab in this repo. It calls update.sh also in this repo.

Install the SystemD service

playground.service

cp playground.service /etc/systemd/system/playground.service
service playground start
systemctl enable playground.service

Install the Nginx reverse proxy

playground-reverse-proxy

cp playground-reverse-proxy /etc/nginx/sites-enabled
service nginx reload

Configure SSL
