machine

Setup

Run setup-ubuntu.sh using sudo or as root

git clone https://github.com/foundeo/machine.git
chmod a+x setup-ubuntu.sh
./setup-ubuntu.sh

Check to make sure it is working by running:

box version

Create a machine.json file

{
    "stage":"production",

    "webserver": {
        "type":"nginx"
    },

    "sites": {
        "example": {
            "path": "/web/example.com/",
            "wwwroot": "",
            "host": "example.com",
            "aliases": ["www.example.com"],
            "webserver": {
                "https": true,
                "ssl_certificate": "/etc/letsencrypt/live/example.com/fullchain.pem",
                "ssl_certificate_key": "/etc/letsencrypt/live/example.com/privkey.pem",
                "ssl_trusted_certificate": "/etc/letsencrypt/live/example.com/chain.pem"
            },
            "deploy": {
                "git": "https://github.com/foundeo/cfmetrics.git"
            }
        }
        
    }
}

Apply the machine.json to the server

The machine command is an admin tool, and is indended to run as root. So always run with sudo or as root, the servers it creates will not run as root.

box machine apply /path/to/machine.json

What does machine apply do?

For each site defined it will do the following:

1. Clones the git repository (deploy/git) to the path
2. Creates a user with the site_id (example in this case)
3. Creates a systemd service (named example in this case) which runs as the user created
4. Sets up a nginx site (creates /etc/nginx/sites-enabled/example.conf)

Let's Encrypt Certificates

If we create a machine.json file with a "https": true, and specify the ssl_certificate and ssl_certificate_key when machine apply runs if the files do not exist in those paths it will create a self signed certificate.

By specifying a path like /etc/letsencrypt/live/example.com/fullchain.pem it will place them in the directory that certbot would use. Let's Encrypt will be able to perform it's domain verfification using a self signed certificate.

# make sure nginx is running 
service nginx status
# move our self signed certs, so certbot can generate new ones
mv /etc/letsencrypt/live/example.com /etc/letsencrypt/live/example.com.selfsigned
# run certbot
certbot certonly --webroot -w /web/example.com/ -d example.com -d www.example.com

Now certbot should generate the certs in the same location we have already specified, we just need to restart nginx for it to use the new certs.

Unattended Upgrades

For Ubuntu:

apt install unattended-upgrades
echo unattended-upgrades unattended-upgrades/enable_auto_updates boolean true | debconf-set-selections
dpkg-reconfigure -f noninteractive unattended-upgrades

This will now automatically install updates, you may still need to reboot on occasion for some of them to apply.
