If you’re using a major Linux distribution, you should be able to find a pre-compiled package in the repositories. If not, then a tar file is available at Duplicity.
sudo apt-get update sudo apt-get install duplicity
Because we are going to authenticate against keystone, it is also necessary to
sudo apt-get install python-keystoneclient
pip install python-keystoneclient
If you intend to create encrypted backups you will also require a GPG key. The
gpg --gen-key command line tool can create a local one for you, see
(GnuPG) for more information on this.
Duplicity requires certain environment variables to be set. One option would be to source a simple bash script like this. The data for these variables can be obtained from your OpenStack RC file.
#!/bin/bash # Swift credentials for Duplicity export SWIFT_USERNAME="email@example.com" export SWIFT_TENANTNAME="mycloudtenant" export SWIFT_AUTHURL="https://api.cloud.catalyst.net.nz:5000/v2.0" export SWIFT_AUTHVERSION="2" # With Keystone you pass the keystone password. echo "Please enter your OpenStack Password: " read -sr PASSWORD_INPUT export SWIFT_PASSWORD=$PASSWORD_INPUT
In order to source this file, run the following from the command line
This will need be done before each Duplicity run if the variables are not already set.
