From 0a448dd034883c07f85091dbfc9117de7227eb8d Mon Sep 17 00:00:00 2001 From: Chad Smith Date: Thu, 25 May 2017 11:04:55 -0600 Subject: ntp: Add schema definition and passive schema validation. cloud-config files are very flexible and permissive. This adds a jsonsschema definition to the cc_ntp module and validation functions in cloudinit/config/schema which will log warnings about invalid configuration values in the ntp section. A cmdline tools/cloudconfig-schema is added which can be used in our dev environments to quickly attempt to exercise the ntp schema. It is also exposed as a main in cloudinit.config.schema. (python3 -m cloudinit.config.schema) LP: #1692916 --- tools/cloudconfig-schema | 35 +++++++++++++++++++++++++++++++++++ 1 file changed, 35 insertions(+) create mode 100755 tools/cloudconfig-schema (limited to 'tools') diff --git a/tools/cloudconfig-schema b/tools/cloudconfig-schema new file mode 100755 index 00000000..32f0d61e --- /dev/null +++ b/tools/cloudconfig-schema @@ -0,0 +1,35 @@ +#!/usr/bin/env python3 +# This file is part of cloud-init.
