I've got a general question about how the scripts for version 11 configure the listen address of 0.0.0.0, it doesn't look like it relies directly on a postgresql.conf file but the Dockerfile does take steps to modify the postgresql.conf.sample file. How are the listening addresses of ipv4 0.0.0.0 and ipv6 :: configured?

We edit postgresql.conf.sample since it is the source of /var/lib/postgresql/data/postgresql.conf when initdb runs.

See also: #105 (comment) and #127.

See also the "Database Configuration" on the Docker Hub docs (https://hub.docker.com/_/postgres/ and official-images/docs)

If you are seeing the empty listen_address in the entrypoint, that is just for the temporary server that is started for initial setup and /docker-entrypoint-initdb.d/ scripts

postgres/docker-entrypoint.sh

Lines 127 to 129 in a8613f4

pg_ctl -D "$PGDATA" \
-o "-c listen_addresses=''" \
-w start
