-The 'OpenNebula' DataSource supports the OpenNebula contextualization disk.
-
-The following criteria are required to be identified by
-DataSourceOpenNebula as contextualization disk:
- * must be formatted with iso9660 filesystem or labeled as CDROM
- * must be un-partitioned block device (/dev/vdb, not /dev/vdb1)
- * must contain
- * context.sh
-
-== Content of config-drive ==
- * context.sh
- This is the only mandatory file on context disk, the rest content depends
- on contextualization parameter FILES and thus is optional. It's
- a shell script defining all context parameters. This script is
- processed by bash (/bin/bash) to simulate behaviour of common
- OpenNebula context scripts. Processed variables are handed over
- back to cloud-init for further processing.
-
-== Configuration ==
-Cloud-init's behaviour can be modified by context variables found
-in the context.sh file in the folowing ways (variable names are
-case-insensitive):
- * dsmode:
- values: local, net, disabled
- default: None
-
- Tells if this datasource will be processed in local (pre-networking) or
- net (post-networking) stage or even completely disabled.
-
- * ssh_key:
- default: None
- If present, these key(s) will be used as the public key(s) for
- the instance. More keys can be specified in this single context
- variable, but each key must be on it's own line. I.e. keys must
- be separated by newlines.
-
- * hostname:
- default: None
- Custom hostname for the instance.
-
- * public_ip:
- default: None
- If hostname not specified, public_ip is used to DNS resolve hostname.
-
- * 'user_data' or 'userdata':
- default: None
- This provides cloud-init user-data. See other documentation for what
- all can be present here.
