Export data from a cloud

This will use the configuration for a cloud named undercloud from your clouds.yaml file, which can be located in your current working directory, in $HOME/.config/openstack/clouds.yaml, or in /etc/openstack.clouds.yaml.

A clouds.yaml file looks something like:

clouds:
  undercloud:
    identity_interface: admin
    identity_api_version: 3
    auth:
      password: SECRET
      auth_url: https://192.168.24.2:13000/v2.0
      username: admin
      tenant_name: admin

Once you have a clouds.yaml file in place, you could use a command like the following to export all exportable data into a local folder named data:

$ mkdir data
$ os-migrate export --os-cloud undercloud -D data

Which will produce the following output:

starting export of openstack data to /home/stack/os-migrate/data
exporting image data
exporting compute data
exporting identity data
finished export

And a collection of files in your data directory:

$ ls data
compute.json  identity.json  image.json
