# Default values are optimized for production to avoid having to configure

# However it should be easy to get going in development too. If you see an
# uncommented option that means it's either mandatory to set or it's being
# overwritten in development to make your life easier.

# In development we want all services to start but in production you don't
# need the asset watchers to run since assets get built into the image.

# If you're running native Linux and your uid:gid isn't 1000:1000 you can set

# The bind port for puma.
#
# Be warned that if you change this value you'll need to change 8000 in both
# your Dockerfile and in a few spots in docker-compose.yml due to the nature of
# how this value can be set (Docker Compose doesn't support nested ENV vars).

# Be warned that if you change this value you'll need to change 28080 in a few

# The Action Cable address that will be accessible over HTTP. In production
# you would typically have this reverse proxied to a sub-domain with nginx, in
# which case you would set something like: ws://cable.example.com
#
# This is one case where it defaults to a development value because it's not
# possible for me to know what domain name you'll be using.

# What ip:port should be published back to the Docker host for the app server?

# is being overwritten in dev to be compatible with more dev environments.
#
# If you have a port conflict because something else is using 8000 then you
# can either stop that process or change 8000 to be something else.
