MDATA-LIST(1) Metadata Commands MDATA-LIST(1)

mdata-list -- Fetch the list of available metadata key-value pairs.


The mdata-list command allows the user (or a script) to query the metadata for a guest instance running in a SmartDataCenter (SDC) cloud. Metadata values are generally set programmatically via CloudAPI, or during interactive provisioning via a Web Portal. They may also be set from within the instance with the mdata-put command. The value of a key-value pair may be obtained by passing its name to the mdata-get command.
The list of all customer-provided metadata key-value pairs will be printed to stdout. If the metadata service is unavailable at the time of the request, this command will block waiting for it to become available. Non-transient failures will cause the program to exit with a non-zero status. Depending on the nature of the error, some diagnostic output may be printed to stderr.

The following exit values are returned:
Successful completion.
The list of key-value pairs was emitted to stdout.
An error occurred.
An unexpected error condition occurred, which is believed to be a non-transient condition. Retrying the request is not expected to resolve the error condition; either a software bug or misconfiguration exists.
A usage error occurred.
Malformed arguments were passed to the program. Check the usage instructions to ensure valid arguments are supplied.
