freenas-iocage-caddy

The aim is to develop a script to install Caddy V2 in a FreeNAS jail

Currently supported

The centrepiece is a rc.d script, which supports default methods such as service caddy stop and service caddy status, but also includes a modifed service caddy start method to support the Caddy V2 executable as well as the following extra commands:

service caddy reload - A config reload with zero downtime. More info at https://caddyserver.com/docs/command-line#caddy-reload service caddy validate - Check for a valid Caddyfile configuration. More info at https://caddyserver.com/docs/command-line#caddy-validate

Additional commands may be added at a later stage if deemed useful.

For other configurable script parameters, refer to the comments at the top of the rc.d script. At this stage, configurable script parameters include:

caddy_enable - Set to enable caddy. The default is disabled. caddy_bin_path - location of the Caddy executable. The default is /usr/local/bin/caddy. caddy_config_path - location of the Caddyfile. The default is /usr/local/www/Caddyfile

To change the defaults add lines to /etc/rc.conf. For example: sysrc caddy_enable="YES" sysrc caddy_bin_path="/usr/local/sbin/caddy"

Additional configrable script parameters may be added at a later stage if deemed useful.

To Do

Build the install script

The script will mirror the steps below, that are presently manually executed.

# Set up the jail
iocage create --name="caddyv2" -r 11.3-RELEASE ip4_addr="vnet0|10.1.1.45/24" defaultrouter="10.1.1.1" boot="on" host_hostname="caddyv2" vnet="on"
iocage console caddyv2
pkg install nano ca_root_nss

# Install the rc.d script
mkdir -p /usr/local/etc/rc.d && cd /usr/local/etc/rc.d
nano caddy # Paste in the text from includes/caddy
chmod +x caddy

# Create the Caddyfile
mkdir -p /usr/local/www && cd /usr/local/www
nano Caddyfile # Paste in the 'Hello World' text from includes/Caddyfile

# Install the Caddy V2 executable
 fetch https://github.com/caddyserver/caddy/releases/download/v2.0.0/caddy_2.0.0_freebsd_amd64.tar.gz
 tar -xzvf caddy_2.0.0_freebsd_amd64.tar.gz
 rm caddy_2.0.0_freebsd_amd64.tar.gz

# Start and test the Caddy installation
 sysrc caddy_enable="YES"
 Restart the jail.
 In a browser, enter jail_IP:2015. You should see 'Hello World' returned.
