Nova Snap
This repository contains the source code of the snap for the OpenStack Compute service, Nova.
This snap specifically provides the compute controller daemons as part of a snap based OpenStack deployment.
Installing this snap
The nova snap can be installed directly from the snap store:
sudo snap install [--edge] nova
Configuring Nova
Snaps run in an AppArmor and seccomp confined profile, so don't read
configuration from /etc/nova on the hosting operating system install.
This snap supports configuration via the $SNAP_COMMON writable area for the snap:
etc
├── nova
│ ├── nova.conf
└── nova.conf.d
├── database.conf
├── nova-snap.conf
└── keystone.conf
The nova snap can be configured in a few ways.
Firstly the nova-server daemon will detect and read etc/nova/nova.conf
if it exists so you can reuse your existing tooling to write to this file
for classic style configuration.
Alternatively the nova daemons will load all configuration files from
etc/nova.conf.d - in the above example, database and keystone authtoken
are configured using configuration snippets in separate files in
etc/nova.conf.d.
For reference, $SNAP_COMMON is typically located under
/var/snap/nova/common.
Managing Nova
Currently all snap binaries must be run as root; for example, to run the nova-manage binary use:
sudo nova.manage
Restarting Nova services
To restart all nova services:
sudo systemctl restart snap.nova.*
or restart services individually:
sudo systemctl restart snap.nova.api
Building the Nova snap
Simply clone this repository and then install and run snapcraft:
git clone https://github.com/openstack-snaps/snap-nova
sudo apt install snapcraft
cd nova
snapcraft
