From ca8a5abf71bd885a80f15f3d743eddfc6371af13 Mon Sep 17 00:00:00 2001 From: Devan Goodwin Date: Mon, 9 Nov 2015 13:01:30 -0400 Subject: Read etcd data dir from appropriate config file. Rather than assuming the etcd data dir, we now read if from master-config.yaml if using embedded etcd, otherwise from etcd.conf. Doing so now required use of PyYAML to parse config file when gathering facts. Fixed discrepancy with data_dir fact and openshift-enterprise deployment_type. --- roles/openshift_facts/library/openshift_facts.py | 51 +++++++++++++++++++++--- roles/openshift_facts/tasks/main.yml | 7 +++- 2 files changed, 50 insertions(+), 8 deletions(-) (limited to 'roles/openshift_facts') diff --git a/roles/openshift_facts/library/openshift_facts.py b/roles/openshift_facts/library/openshift_facts.py index 6d6c99c97..932bfd441 100755 --- a/roles/openshift_facts/library/openshift_facts.py +++ b/roles/openshift_facts/library/openshift_facts.py @@ -20,6 +20,8 @@ EXAMPLES = ''' import ConfigParser import copy import os +import StringIO +import yaml from distutils.util import strtobool from distutils.version import LooseVersion from netaddr import IPNetwork @@ -526,18 +528,55 @@ def set_aggregate_facts(facts): first_svc_ip = str(IPNetwork(facts['master']['portal_net'])[1]) all_hostnames.add(first_svc_ip) internal_hostnames.add(first_svc_ip) - - if facts['master']['embedded_etcd']: - facts['master']['etcd_data_dir'] = os.path.join( - facts['common']['data_dir'], 'openshift.local.etcd') - else: - facts['master']['etcd_data_dir'] = '/var/lib/etcd' + _add_etcd_data_dir_fact(facts) facts['common']['all_hostnames'] = list(all_hostnames) facts['common']['internal_hostnames'] = list(internal_hostnames) return facts + +def _add_etcd_data_dir_fact(facts): + """ + If using embedded etcd, loads the data directory from master-config.yaml. + + If using standalone etcd, loads ETCD_DATA_DIR from etcd.conf. + + If anything goes wrong parsing these, the fact will not be set. + """ + if facts['master']['embedded_etcd']: + try: + # Parse master config to find actual etcd data dir: + master_cfg_path = os.path.join(facts['common']['config_base'], + 'master/master-config.yaml') + master_cfg_f = open(master_cfg_path, 'r') + config = yaml.safe_load(master_cfg_f.read()) + master_cfg_f.close() + + facts['master']['etcd_data_dir'] = \ + config['etcdConfig']['storageDirectory'] + # We don't want exceptions bubbling up here: + # pylint: disable=broad-except + except Exception: + pass + else: + # Read ETCD_DATA_DIR from /etc/etcd/etcd.conf: + try: + # Add a fake section for parsing: + ini_str = '[root]\n' + open('/etc/etcd/etcd.conf', 'r').read() + ini_fp = StringIO.StringIO(ini_str) + config = ConfigParser.RawConfigParser() + config.readfp(ini_fp) + etcd_data_dir = config.get('root', 'ETCD_DATA_DIR') + if etcd_data_dir.startswith('"') and etcd_data_dir.endswith('"'): + etcd_data_dir = etcd_data_dir[1:-1] + facts['master']['etcd_data_dir'] = etcd_data_dir + # We don't want exceptions bubbling up here: + # pylint: disable=broad-except + except Exception: + pass + + def set_deployment_facts_if_unset(facts): """ Set Facts that vary based on deployment_type.
