From cd381ae7f8716a1dccce78d08f5776ec94cd31b7 Mon Sep 17 00:00:00 2001 From: Joel Diaz Date: Thu, 4 Jan 2018 13:55:23 +0000 Subject: un-hardcode default subnet az allow defining 'default_az' for one of the subnets in the vpc structure, and pull that default_az and set it to openshift_aws_subnet_az. this should allow one less variable to have to be defined/overridded (openshift_aws_subnet_az) when using non-default (us-east-1) regions update provisioning_vars.yml.example to show an example VPC structure --- roles/lib_utils/filter_plugins/openshift_aws_filters.py | 16 ++++++++++++++++ roles/openshift_aws/defaults/main.yml | 5 +++-- 2 files changed, 19 insertions(+), 2 deletions(-) (limited to 'roles') diff --git a/roles/lib_utils/filter_plugins/openshift_aws_filters.py b/roles/lib_utils/filter_plugins/openshift_aws_filters.py index dfcb11da3..f16048056 100644 --- a/roles/lib_utils/filter_plugins/openshift_aws_filters.py +++ b/roles/lib_utils/filter_plugins/openshift_aws_filters.py @@ -67,8 +67,24 @@ class FilterModule(object): return tags + @staticmethod + def get_default_az(subnets): + ''' From a list of subnets/AZs in a specific region (from the VPC + structure), return the AZ that has the key/value + 'default_az=True.'
