From f752eaccbb1a5f0e2c1d36502f755d022a21d073 Mon Sep 17 00:00:00 2001 From: Jason DeTiberus Date: Fri, 10 Jul 2015 15:04:26 -0400 Subject: Playbook updates for clustered etcd - Add support to bin/cluster for specifying etcd hosts - defaults to 0, if no etcd hosts are selected, then configures embedded etcd - Updates for the byo inventory file for etcd and master as node by default - Consolidation of cluster logic more centrally into common playbook - Added etcd config support to playbooks - Restructured byo playbooks to leverage the common openshift-cluster playbook - Added support to common master playbook to generate and apply external etcd client certs from the etcd ca - start of refactor for better handling of master certs in a multi-master environment. - added the openshift_master_ca and openshift_master_certificates roles to manage master certs instead of generating them in the openshift_master role - added etcd host groups to the cluster update playbooks - aded better handling of host groups when they are either not present or are empty. - Update AWS readme --- playbooks/common/openshift-cluster/config.yml | 61 +++++++ .../set_master_launch_facts_tasks.yml | 6 +- .../set_node_launch_facts_tasks.yml | 6 +- playbooks/common/openshift-master/config.yml | 199 ++++++++++++++++++++- playbooks/common/openshift-node/config.yml | 39 ++-- 5 files changed, 280 insertions(+), 31 deletions(-) (limited to 'playbooks/common') diff --git a/playbooks/common/openshift-cluster/config.yml b/playbooks/common/openshift-cluster/config.yml index 14ffa928f..0779cfe47 100644 --- a/playbooks/common/openshift-cluster/config.yml +++ b/playbooks/common/openshift-cluster/config.yml @@ -1,4 +1,65 @@ --- +- name: Populate config host groups + hosts: localhost + gather_facts: no + tasks: + -
