example docker compose and caddy config for plex, radarr, sonarr, etc.

# Some services use paths on my main domain, such as home.domain/sonarr. 
# Others use subdomains, such as plex.home.domain.
# If I were starting over, I'd use all subdomains. Caddy just magically
# obtains SSL certificates for subdomains, some services require some 
# extra work and configuration to work at a path.

###
# I've left my internal IP and port addresses as examples, but you'll
# want to change them all to match the actual IPs for your services.
#
# Also, some of the ports I use are not the standard ports for those services.
# So make sure to use the real port your services use and/or you map in your 
# docker-compose.yml.

# TO RELOAD CADDY after config changes without restarting container:
# 1. start a docker shell in the Caddy container
# 2. cd /etc/caddy
# 3. caddy reload

version: "3.7"

###
# This lives, for me, in a /caddy folder inside my main /docker folder. I run 
# docker compose up -d twice - once in the main docker folder, and once in 
# the caddy folder.
#
# I don't think there is any advantage to doing it like this, instead of adding 
# Caddy in as another entry in the main docker-compose.yml file. But when I was 
# first playing around with Caddy, I wasn't sure if I was going to use it, and I 
# wanted to keep it separate, and it worked, so I never changed it.
