#part-handler
# vi: syntax=python ts=4
# this is an example of a version 2 part handler.
# the differences between the initial part-handler version
# and v2 is:
# * handle_part receives a 5th argument, 'frequency'
# frequency will be either 'always' or 'per-instance'
# * handler_version must be set
#
# A handler declaring version 2 will be called on all instance boots, with a
# different 'frequency' argument.
handler_version = 2
def list_types():
# return a list of mime-types that are handled by this module
return(["text/plain", "text/go-cubs-go"])
def handle_part(data, ctype, filename, payload, frequency):
# data: the cloudinit object
# ctype: '__begin__', '__end__', or the specific mime-type of the part
# filename: the filename for the part, or dynamically generated part if
# no filename is given attribute is present
# payload: the content of the part (empty for begin or end)
# frequency: the frequency that this cloud-init run is running for
# this is either 'per-instance' or 'always'. 'per-instance'
# will be invoked only on the first boot. 'always' will
# will be called on subsequent boots.
