This repository contains the source for the OpenStack Manila Data snap.
The manila-data daemon is part of OpenStack Manila (https://docs.openstack.org/manila/latest/), the Shared Filesystems service. It handles data-intensive operations such as:
The snap packages the upstream manila-data binary together with Ceph (ceph-common) and NFS support, manages its configuration files via Jinja2 templating, and runs the service as a strictly-confined snap daemon.
This snap is designed to be used with a deployed OpenStack control plane such as delivered by Sunbeam (https://canonical-openstack.readthedocs-hosted.com/en/latest/how-to/features/shared-filesystem/).
Getting Started
Installation
Install the snap from the Snap Store:
sudo snap install manila-data
Required configuration
The service will not start until the database and message queue connections are provided:
sudo snap set manila-data \
database.url=mysql+pymysql://manila:password@10.152.183.210/manila
sudo snap set manila-data \
rabbitmq.url=rabbit://manila:supersecure@10.152.183.212:5672/openstack
Once both values are set the configure hook will render the configuration files and start (or restart) the manila-data daemon automatically.
Verifying the service
sudo snap services manila-data
Logs are written to syslog. You can also inspect the snap-specific log:
sudo snap logs manila-data
Configuration Reference
All options are set with snap set manila-data <key>=<value> and read with snap get manila-data <key>.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap can be installed from the command line on openSUSE Leap 15.x and Tumbleweed.
You need first add the snappy repository from the terminal. Choose the appropriate command depending on your installed openSUSE flavor.
Tumbleweed:
sudo zypper addrepo --refresh https://download.opensuse.org/repositories/system:/snappy/openSUSE_Tumbleweed snappy
Leap 15.x:
sudo zypper addrepo --refresh https://download.opensuse.org/repositories/system:/snappy/openSUSE_Leap_15.6 snappy
If needed, Swap out openSUSE_Leap_15. for, openSUSE_Leap_16.0 if you’re using a different version of openSUSE.
With the repository added, import its GPG key:
sudo zypper --gpg-auto-import-keys refresh
Finally, upgrade the package cache to include the new snappy repository:
sudo zypper dup --from snappy
Snap can now be installed with the following:
sudo zypper install snapd
You then need to either reboot, logout/login or source /etc/profile to have /snap/bin added to PATH.
Additionally, enable and start both the snapd and the snapd.apparmor services with the following commands:
sudo systemctl enable --now snapd
sudo systemctl enable --now snapd.apparmor
To install manila-data, simply use the following command:
sudo snap install manila-data
Browse and find snaps from the convenience of your desktop using the snap store snap.
