From 0cf6db3617e0cebeb89c4809396f84360827e96c Mon Sep 17 00:00:00 2001 From: Chad Smith Date: Tue, 5 Dec 2017 16:42:35 -0700 Subject: Datasources: Formalize DataSource get_data and related properties. Each DataSource subclass must define its own get_data method. This branch formalizes our DataSource class to require that subclasses define an explicit dsname for sourcing cloud-config datasource configuration. Subclasses must also override the _get_data method or a NotImplementedError is raised. The branch also writes /run/cloud-init/instance-data.json. This file contains all meta-data, user-data and vendor-data and a standardized set of metadata keys in a json blob which other utilities with root-access could make use of. Because some meta-data or user-data is potentially sensitive the file is only readable by root. Generally most metadata content types should be json serializable. If specific keys or values are not serializable, those specific values will be base64encoded and the key path will be listed under the top-level key 'base64-encoded-keys' in instance-data.json. If json writing fails due to other TypeErrors or UnicodeDecodeErrors, a warning log will be emitted to /var/log/cloud-init.log and no instance-data.json will be created. --- cloudinit/analyze/dump.py | 8 +------- 1 file changed, 1 insertion(+), 7 deletions(-) (limited to 'cloudinit/analyze/dump.py') diff --git a/cloudinit/analyze/dump.py b/cloudinit/analyze/dump.py index ca4da496..b071aa19 100644 --- a/cloudinit/analyze/dump.py +++ b/cloudinit/analyze/dump.py @@ -2,7 +2,6 @@ import calendar from datetime import datetime -import json import sys from cloudinit import util @@ -132,11 +131,6 @@ def parse_ci_logline(line): return event -def json_dumps(data): - return json.dumps(data, indent=1, sort_keys=True, - separators=(',', ': ')) - - def dump_events(cisource=None, rawdata=None): events = [] event = None @@ -169,7 +163,7 @@ def main(): else: cisource = sys.stdin - return json_dumps(dump_events(cisource)) + return util.json_dumps(dump_events(cisource)) if __name__ == "__main__": -- cgit v1.2.3
