Enabling Freezer in Devstack

This directory contains the Freezer DevStack plugin.

Download Devstack:

git clone
cd devstack

To configure the Freezer scheduler and agent with DevStack, you will need to enable this plugin by adding one line to the local section of your local.conf file.

To enable the plugin, add a line of the form:

enable_plugin freezer <GITURL> [GITREF]


<GITURL> is the URL of a freezer repository
[GITREF] is an optional git ref (branch/ref/tag).  The default is master.

For example:

enable_plugin freezer master

Then run devstack normally:


This is a sample local.conf file for freezer developer:



# only install keystone/horizon/swift in devstack
# disable_all_services
# enable_service key mysql s-proxy s-object s-container s-account horizon

enable_plugin freezer master
enable_plugin freezer-api master
enable_plugin freezer-tempest-plugin master
enable_plugin freezer-web-ui master

export FREEZER_BACKEND='sqlalchemy'
