compose.yml

# This compose file is for development use ONLY!

# In order to preserve file ownership and permissions,
# create a '.env' file containing GTN_UID and GTN_GID.

# You may set a custom ruby tag using
# GTN_RUBY_TAG in your '.env' file

# In order to use this composition from multiple locations
# on one host, you also need to specify 'COMPOSE_PROJECT_NAME'
# in your '.env' file, so multiple compositions will not interfere.

# If you would like to use multiple compositions in parallel,
# you also need to set the GTN_PORT and GTN_RELOAD_PORT
# in your '.env' file, so that ports do not collide.

# In order to use this composition with rootless container platform
# installations, e.g. podman or docker rootless, please review
# user namespace settings of your installation.
# If you have set it to 'host', you need to set GTN_UID and GTN_GID
# to 0 in order to preserve correct file ownership.
