# Why we are running with network_mode: host
# Wow this has been awful. We run three things in docker: mysql, keycloak, and the backend server.
# The backend-server needs to talk to the other two.
#
# In order to talk to keycloak, it needs to go through localhost so that it can communicate with
# keycloak using the same url as the frontend so that tokens can be properly validated.
# If the domains are different, keycloak invalidates the token. There may be a way to change
# this but I didn't find it.
#
# In order for the backend server to talk to the mysql server, they need to be on the same network.
# I tried splitting it out where the mysql runs on a custom network and the backend runs on both
# the custom network AND with localhost. Nothing I tried worked and googling didn't help. They
# only ever mentioned one thing or using host.docker.internal which would cause the domains to
# be different.
#
# So instead we are running with both the mysql server and the backend server in host netowrk mode.
# There may be a better way to do this but if it works, then it works.
