This PR adds the ability to extend the limited set of
CASSANDRA_xxx
styleenv
vars that update thecassandra.yaml
viadocker_entrypoint.sh
This is done by setting an
env
variableEXTEND_CONFIG
with a space separated list of config keys that thedocker_entrypoint.sh
will add to it's limited list of keys to replace incassandra.yaml
.One could add this to a
docker-compose.yml
e.g.:The above would recognize the last 3
env
variables and set these appropriately in thecassandra.yaml
config file.
