Ports have to be released on re-deployJune 2018

When I restart Okapi (for example in order to pull a current, stable version) I have to re-deploy the modules afterwards. But this didn't work at first try, because the ports 9131 - ... were still not free. Before I could re-deploy the modules, I had to restart the Docker service. This releases the ports.

Under SLES, it works like this

systemctl stop docker.service
#  this releases ports 9131 - ...
systemctl start docker.service
Multiple on SlackFOLIO requires md5 in pg_hba.conf2018, 2019, 2020, 2021, 2022

Installation fails with this error message:

Opening SQLConnection failed: com/ongres/scram/common/stringprep/StringPreparation
java.lang.NoClassDefFoundError: com/ongres/scram/common/stringprep/StringPreparation

Cause:

FOLIO doesn't support scram-sha-256 password authentication.

Solution:

Configure md5 password authentication in PostgreSQL's pg_hba.conf file.
