Install Trove in DevStack

This page describes how to set up a working development environment that can be used in deploying Trove on latest releases of Ubuntu.

Config DevStack with Trove

Trove can be enabled in devstack by using the plug-in based interface it offers.

Note

The following steps have been fully verified both on Ubuntu 22.04/24.04 and Rocky Linux 9.

Note

Make sure that you have at least 16 GB of RAM available before deploying DevStack with Trove, as it requires significant memory to run properly.

Start by cloning the devstack repository using a non-root user(the default user is ubuntu) and change to devstack directory:

git clone https://opendev.org/openstack/devstack
cd devstack/

Create the local.conf file with the following minimal devstack configuration, change the HOST_IP to your own devstack host IP address:

[[local|localrc]]
RECLONE=False
HOST_IP=<your-host-ip-here>

Take a look at the options you could use to customize the Trove installation.

Running devstack

Run the stack.sh script:

./stack.sh

After it completes, you can see there is a MySQL datastore available to create Trove instance:

$ openstack datastore version list mysql
+--------------------------------------+------------------+
| ID                                   | Name             |
