MDATA-LIST(8) Metadata Commands MDATA-LIST(8)
-- Fetch the list of available metadata key-value pairs.
command allows the user (or a script) to query the
metadata for a guest instance running in a SmartDataCenter (SDC)
Metadata values are generally set programmatically via CloudAPI
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
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: 0

resolve the error condition; either a software bug or
misconfiguration exists. 3
