Hi,
We are trying to set up a Dovecot Docker image with dynamic database configuration based on environment variables, however the variables do not appear to be expanded in the "connect=" string of the SQL config.
The documentation states that environment variables, being listed under global variables, work "everywhere":
https://doc.dovecot.org/configuration_manual/config_file/config_variables/#v...
However, the source code for driver-pgsql.c indicates that the connect string is never expanded:
https://github.com/dovecot/core/blob/master/src/lib-sql/driver-pgsql.c#L297
For reference, this is my configuration. dovecot.conf:
import_environment = PASSDB_USER PASSDB_DBNAME PASSDB_PASSWORD passdb { override_fields = proxy=y driver = sql args = /etc/dovecot/dovecot-sql.conf.ext }
/etc/dovecot/dovecot-sql.conf.ext:
driver = pgsql connect = host=mail-passdb dbname=%{env:PASSDB_DBNAME} user=%{env:PASSDB_USER} password=%{env:PASSDB_PASSWORD}
Does anyone have any suggestions for how to connect to a database without hardcoding the connection parameters in the Dovecot config, which does not involve patching driver-pgsql.c to make the variable expansion?
Best regards, Eirik Rye
