Subject: Mount PostgreSQL Data from Persistent Volume
X-Git-Tag: 6.0.0~107
X-Git-Url: https://gerrit.opnfv.org/gerrit/gitweb?a=commitdiff_plain;h=34f15a071a9df12986654593193235a21a774fc8;p=pharos.git

Mount PostgreSQL Data from Persistent Volume

Each time the postgresql container is torn down the database is lost.
By using a presistent volume managed outside of docker compose, the
postgresql data can persist across updates and service restarts.

The volume needs to exist before the postgres container can start: this
is done with the 'make data' command.

Note: postgres container creates a volume at /var/lib/postgresql/data.
Mounting at this location ensures the data is persisted into the
external volume.
