NAME
mdata-put -- Set the value of a metadata key-value pair.
SYNOPSIS
/usr/sbin/mdata-put keyname [ value ]
DESCRIPTION
The mdata-put command allows the user (or a script) to modify 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. The value of a key-value pair may be obtained by
passing its name to the mdata-get command.
The key-value pair named keyname will be updated in the metadata store for this instance. If a value
argument is provided on the command-line, then that value will be used. Otherwise, if stdin is not a
tty, the value will be read from stdin.
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, such as the non-existence of the requested keyname, 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.
EXIT STATUS
The following exit values are returned:
0
Successful completion.
The requested keyname was valid, and its value was updated.
2
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.
3
A usage error occurred.
Malformed arguments were passed to the program. Check the usage instructions to ensure valid
arguments are supplied.
