# matrix-synapse-reverse-proxy companion is a role which brings up a containerized nginx webserver which helps with reverse-proxying to Synapse.
#
# When Synapse is NOT running in worker-mode, reverse-proxying is relatively simple (everything goes to `matrix-synapse:XXXX`).
#
# When Synapse workers are enabled, however, the reverse-proxying configuration is much more complicated.
# Certain requests need to go to certain workers, etc.
# In the past, the main reverse proxy (`matrix-synapse-reverse-proxy-companion`) was handling request routing to the appropriate workers,
# but that only worked well for external requests (from outside of the Matrix server itself).
#
# Without the help of `matrix-synapse-reverse-proxy-companion`, internal services (like Dimension) that would like to talk to Synapse over the container network
# did not have an endpoint for Synapse that they could be pointed to and have it just work.
# If `matrix-synapse-reverse-proxy-companion` was enabled, Dimension could be pointed to its vhost handling Synapse and routing to the appropriate workers,
# but when `matrix-synapse-reverse-proxy-companion` was disabled, this helpful functionality was not available and the best we could do
# is point Dimension to the main Synapse process at `matrix-synapse:XXXX` itself.
# Doing that breaks requests that need to go to specific workers.
# See: https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/2090
#
# What this role does is, it extracts all the Synapse request routing out of the `matrix-synapse-reverse-proxy-companion` role here,
# and makes the `matrix-synapse-reverse-proxy-companion` container service represent Synapse and route appropriately,
# regardless of whether workers are enabled or disabled.
# All other playbook services can then forget about `matrix-synapse` or `matrix-synapse-whatever-worker`, etc.,
# and just use `matrix-synapse-reverse-proxy-companion` as their request destination.
