Limbo - LXD Image Import / Export

Limbo is a tool to help import and export LXD images to/from different storage backends.

Storage Backends

• OpenStack Swift

Installation

Usage

Export

The most basic use of Limbo is:

$ limbo export swift --name foo --stop

This will temporarily stop (--stop) a running container called foo and export it to a Swift storage container called limbo. The Swift container limbo must exist first.

To have Limbo automatically create the storage container, do:

$ limbo export swift --name foo --stop --create-storage-container

To specify a custom storage container name, do:

$ limbo export swift --name foo --stop --create-storage-container --storage-container backups

If you already have an image, do:

$ limbo export swift --name foo-image --type image --create-storage-container

Limbo can encrypt an image.

Warning: I am not a crypto expert. I make no guarantees about the integrity of this feature.

$ limbo export swift --name foo --stop --encrypt --pass "some passphrase"

Import

Importing an image works much the same way as exporting, but the data goes in the opposite direction.

To import an image:

$ limbo import swift --object-name foo

This will look for an object named foo in a Swift storage container called limbo and import it into LXD as foo.

To specify an alternative storage container name and LXD image name, do:

$ limbo import swift --storage-container backups --object-name foo --name foobar

To decrypt a previously encrypted image, do:

$ limbo import swift --object-name foo --encrypt --pass "some passphrase"

OpenStack Swift

You can use a standard openrc file to authenticate with Swift:

$ source openrc
$ limbo export swift ...

To take advantage of Swift Object Versioning/Archiving, do:

$ limbo export swift --name foo --stop --create-storage-container --storage-container backups --archive
