HBOX_WEB_HOST examples

Value	Notes
0.0.0.0	Visible all interfaces (default behaviour)
127.0.0.1	Only visible on same host
100.64.0.1	Only visible on a specific interface (e.g., VPN in a VPS).
unix?path=/run/homebox.sock	Listen on unix socket at specified path
sysd?name=homebox.socket	Listen on systemd socket

For unix and systemd socket address syntax and available options, see the anyhttp address-syntax documentation.

Private network example

Below example starts homebox in an isolated network. The process cannot make any external requests (including check for newer release) and thus more secure.

❯ sudo systemd-run --property=PrivateNetwork=yes --uid $UID --pty --same-dir --wait --collect homebox --web-host "unix?path=/run/user/$UID/homebox.sock"

Systemd socket example

In the example below, Homebox listens on a systemd socket securely so that only the webserver (Caddy) can access it. Other processes/containers on the host cannot connect to Homebox directly, bypassing the webserver.

File: homebox.socket

# /usr/local/lib/systemd/system/homebox.socket
[Unit]
Description=Homebox socket

[Socket]
ListenStream=/run/homebox.sock
SocketGroup=caddy
SocketMode=0660

[Install]
WantedBy=sockets.target

File: homebox.service

# /usr/local/lib/systemd/system/homebox.service
[Unit]
Description=Homebox
After=network.target
Documentation=https://homebox.software

[Service]
DynamicUser=yes
StateDirectory=homebox
Environment=HBOX_WEB_HOST=sysd?name=homebox.socket
WorkingDirectory=/var/lib/homebox

ExecStart=/usr/local/bin/homebox

NoNewPrivileges=yes
CapabilityBoundingSet=
RestrictNamespaces=true
SystemCallFilter=@system-service

Usage:

systemctl start homebox.socket

::: warning Security Considerations For postgreSQL in production:

• Do not use the default postgres user
• Do not use the default postgres database
• Always use a strong unique password
• Always use SSL (sslmode=require or sslmode=verify-full)
• Consider using a connection pooler like pgbouncer

For SQLite in production:

• Secure file permissions for the database file (e.g. chmod 600)
• Use a secure directory for the database file
• Use a secure backup strategy
• Monitor the file size and consider using a different database for large installations :::

::: tip CLI Arguments If you're deploying without docker you can use command line arguments to configure the application. Run homebox --help for more information.

Usage: api [options] [arguments]
