notes:
|
|
|
|
|
- To create a new server at least the C(name), C(ssh_key), C(image) and C(flavor) options are required.
|
|
|
|
|
- If more than one server with the name given by the C(name) option exists, execution is aborted.
|
|
|
|
|
- Once a server is created all parameters except C(state) are read-only. You can't change the name, flavor or any other property. This is a limitation
|
|
|
|
|
of the cloudscale.ch API. The module will silently ignore differences between the configured parameters and the running server if a server with the
|
|
|
|
|
correct name or UUID exists. Only state changes will be applied.

|
- Since version 2.8, I(uuid) and I(name) or not mututally exclusive anymore.
|
|
|
|
|
- If I(uuid) option is provided, it takes precedence over I(name) for server selection. This allows to update the server's name.
|
|
|
|
|
- If no I(uuid) option is provided, I(name) is used for server selection. If more than one server with this name exists, execution is aborted.
|
|
|
|
|
- Only the I(name) and I(flavor) are evaluated for the update.
|
|
|
|
|
- The option I(force=true) must be given to allow the reboot of existing running servers for applying the changes.
