# pvc-provisioner client configuration file example
|
||||
#
|
||||
# This configuration file specifies details for the PVC provisioner client
|
||||
# running on this machine. Default values are not supported; the values in
|
||||
# this sample configuration are considered defaults and can be used as-is.
|
||||
#
|
||||
# Copy this example to /etc/pvc/pvc-provisioner.yaml and edit to your needs.
|
||||
#
|
||||
# Alternatively, you may combine this configuration (anything under the
|
||||
# `provisioner` section) with a PVC API configuration in a single file, and
|
||||
# create links between them. By default, the only difference is the
|
||||
# provisioner header and the listen port specifically.
