# Here is a script to deploy cert to Synology DSM
|
|
#
|
|
# it requires the jq and curl are in the $PATH and the following
|
|
# environment variables must be set:
|
|
#
|
|
# SYNO_Username - Synology Username to login (must be an administrator)
|
|
# SYNO_Password - Synology Password to login
|
|
# SYNO_Certificate - Certificate description to target for replacement
|
|
#
|
|
# The following environmental variables may be set if you don't like their
|
|
# default values:
|
|
#
|
|
# SYNO_Scheme - defaults to http
|
|
# SYNO_Hostname - defaults to localhost
|
|
# SYNO_Port - defaults to 5000
|
|
#
|
|
#returns 0 means success, otherwise error.
