The latest available documentation for Octavia https://docs.openstack.org/octavia/latest/install/install-ubuntu.html#prerequisites (https://docs.openstack.org/octavia/la...) does not include the provisions to install octaiva with postgresql database

Managed to create db, users but while trying to populate the octavia database in psql using command "octavia-db-manage --config-file /etc/octavia/octavia.conf upgrade head" gives error.

The octaiva alembic migration codes seems to assume that the database is mysql and does not treat the psql database.

eg: /usr/lib/python2.7/site-packages/octavia/db/migration/alembic_migrations/versions/fac584114642_.py op.execute("ALTER TABLE health_monitor DROP PRIMARY KEY," "ADD PRIMARY KEY(id);")

The above code is intended for mysql datanbase and not postgresql.

Please guide how to do octavia db migration for postgresql.

Hi,

This is correct. OpenStack overall (not just Octavia) stopped testing with postgresql some time ago [1] (Pike I think).

If you have a need to use a postgresql database with Octavia I would recommend the following: 1. Open a story on Storyboard for Octavia: https://storyboard.openstack.org/#!/p... with the bug you are seeing. Maybe another to track an RFE for adding postgresql support. 2. Join one of the Octavia IRC weekly meetings and raise the discussion of adding support/testing for postgresql.

We may have some base work in getting devstack/tempest gates to support postgresql.

Also, let the team know if you can help with this effort.
