# Build and run the change server.
#
# This image will launch the server with the default port (port 9000) open.
#
# To run, add the -s argument and the -u argument
# The -u argument takes a Postgres URL.
# The -s argument takes the name of the logical replication slot to create
#
# Each instance of the change server must have a different logical replication
# slot (otherwise, changes will be lost). Furthermore, the logical
# replication slot lasts forever -- when instances are shut down, the slot
# must be removed, or else the database will never be able to purge
# its transaction logs.
#
# For instance:
#
# docker run --rm -t changeserver -s test -u postgres://user:pass@host/databasename?ssl=false
