Registering an Image
|
|
====================
|
|
|
|
Sahara deploys a cluster of machines using images stored in Glance.
|
|
|
|
Each plugin has its own requirements on the image contents (see specific plugin
|
|
documentation for details). Two general requirements for an image are to have
|
|
the cloud-init and the ssh-server packages installed.
|
|
|
|
Sahara requires the images to be registered in the Sahara Image Registry.
|
|
A registered image must have two properties set:
|
|
|
|
* username - a name of the default cloud-init user.
|
|
* tags - certain tags mark image to be suitable for certain plugins. The tags
|
|
depend on the plugin used, you can find required tags in the plugin's
|
|
documentations.
|
|
|
|
The default username specified for these images is different
|
|
for each distribution:
|
