In MAAS 1.5 and later (included in Ubuntu 14.04 Trusty) the architecture has changed, so now the recommended way to import boot images is through the Web UI of MAAS at the "Clusters" page, clicking the "Import boot images" button. Alternatively, using the MAAS CLI commands, run:
$ maas my-maas-session node-groups import-boot-images
The configuration file that defines what images to download is in /etc/maas/bootresources.yaml
. It looks like this:
boot:
sources:
- keyring: /usr/share/keyrings/ubuntu-cloudimage-keyring.gpg
path: http://maas.ubuntu.com/images/ephemeral-v2/releases/
selections:
- arches:
- i386
- amd64
labels:
- release
- rc
release: trusty
subarches:
- generic
- arches:
- i386
- amd64
labels:
- release
release: precise
subarches:
- generic
storage: /var/lib/maas/boot-resources/
To limit what gets downloaded, remove one or more entries from the list of arches, labels or subarches. For example, to only download images for series trusty-release-amd64-generic, leave only this in the file:
boot:
sources:
- keyring: /usr/share/keyrings/ubuntu-cloudimage-keyring.gpg
path: http://maas.ubuntu.com/images/ephemeral-v2/releases/
selections:
- arches:
- amd64
labels:
- release
release: trusty
subarches:
- generic
storage: /var/lib/maas/boot-resources/
Hope this helps! MAAS documentation about that needs to be updated to include this, so thanks for reporting it - I've filed a bug for it.
