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:
The default username specified for these images is different for each distribution:
OS | username |
---|---|
Ubuntu 12,14 | ubuntu |
Fedora | fedora |
CentOS 6.x | cloud-user |
CentOS 7.x | centos |
