Re: Connection to 127.0.0.1 refused in a Dockerfile based on postgres:17-alpine3.20

[Alexander Farber]

I have tried changing the line in the Dockerfile, but it has not helped yet:

ENV POSTGRES_INITDB_ARGS "--set port=6432 --set max_connections=20 --set
max_wal_size=2GB --set listen_addresses=localhost"

ENV POSTGRES_INITDB_ARGS "--set port=6432 --set max_connections=20 --set
max_wal_size=2GB --set listen_addresses='localhost'"

Maybe the quotes get lost somehow when using the "--set" option?

$ grep listen $PGDATA/postgresql.conf
listen_addresses = localhost
