MDATA-LIST(8) Metadata Commands MDATA-LIST(8)


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.
