--from-json [text]
------------------

Provide input to this command as a JSON document from a file using the
file://path-to/file syntax.

The --generate-full-command-json-input option can be used to generate
a sample json file to be used with this command option. The key names
are pre-populated and match the command option names (converted to
camelCase format, e.g. compartment-id --> compartmentId), while the
values of the keys need to be populated by the user before using the
sample file as an input to this command. For any command option that
accepts multiple values, the value of the key can be a JSON array.

Options can still be provided on the command line. If an option exists
in both the JSON document and the command line then the command line
specified value will be used.

For examples on usage of this option, please see our "using CLI with
advanced JSON options" link: https://docs.cloud.oracle.com/iaas/Conte
nt/API/SDKDocs/cliusing.htm#AdvancedJSONOptions
