Enabling Picasso (Functions-as-a-Service) in DevStack
Install Glide
It is required to install Glide on the system in which you plan to run DevStack on, as the Functions service is written in Go and we must fetch dependencies during install. See more info at https://github.com/Masterminds/glide
Download DevStack
export DEVSTACK_DIR=~/devstack
git clone git://git.openstack.org/openstack-dev/devstack.git $DEVSTACK_DIR
Enable the Functions plugin
Enable the plugin by adding the following section to $DEVSTACK_DIR/local.conf
[[local|localrc]]
enable_plugin picasso git@github.com:openstack/picasso.git
