# This script reads environment variables and generates a shared Synapse worker,
|
|
# nginx and supervisord configs depending on the workers requested.
|
|
#
|
|
# The environment variables it reads are:
|
|
# * SYNAPSE_SERVER_NAME: The desired server_name of the homeserver.
|
|
# * SYNAPSE_REPORT_STATS: Whether to report stats.
|
|
# * SYNAPSE_WORKER_TYPES: A comma separated list of worker names as specified in WORKER_CONFIG
|
|
# below. Leave empty for no workers.
|
|
# * SYNAPSE_AS_REGISTRATION_DIR: If specified, a directory in which .yaml and .yml files
|
|
# will be treated as Application Service registration files.
|
|
# * SYNAPSE_TLS_CERT: Path to a TLS certificate in PEM format.
|
|
# * SYNAPSE_TLS_KEY: Path to a TLS key. If this and SYNAPSE_TLS_CERT are specified,
|
|
# Nginx will be configured to serve TLS on port 8448.
|
|
# * SYNAPSE_USE_EXPERIMENTAL_FORKING_LAUNCHER: Whether to use the forking launcher,
|
|
# only intended for usage in Complement at the moment.
|
|
# No stability guarantees are provided.
|
|
# * SYNAPSE_LOG_LEVEL: Set this to DEBUG, INFO, WARNING or ERROR to change the
|
|
# log level. INFO is the default.
|
|
# * SYNAPSE_LOG_SENSITIVE: If unset, SQL and SQL values won't be logged,
|
|
# regardless of the SYNAPSE_LOG_LEVEL setting.
|
|
#
|
|
# NOTE: According to Complement's ENTRYPOINT expectations for a homeserver image (as defined
|
|
# in the project's README), this script may be run multiple times, and functionality should
|
|
# continue to work if so.
