From 139a82349040983a4af7ebd7e09e32a96bc00667 Mon Sep 17 00:00:00 2001 From: Devan Goodwin Date: Thu, 26 Nov 2015 10:40:05 -0400 Subject: Block re-use of master/node as load balancer in attended install. Code was present to catch this in unattended installs but was looking for a host record with both master/node and master_lb set to true, but in the attended installs we were adding a separate host record with the same connect_to. Attended tests can now optionally specify multiple "attempted" strings for the master_lb specification, we'll try to input each if multiple are specified. Cleanup some empty defaults and error messages as well. --- utils/src/ooinstall/cli_installer.py | 35 +++++++++++++++++++++++---------- utils/src/ooinstall/oo_config.py | 4 ++-- utils/test/cli_installer_tests.py | 38 ++++++++++++++++++++++++++++++------ 3 files changed, 59 insertions(+), 18 deletions(-) (limited to 'utils') diff --git a/utils/src/ooinstall/cli_installer.py b/utils/src/ooinstall/cli_installer.py index d7c06745e..a016a5597 100644 --- a/utils/src/ooinstall/cli_installer.py +++ b/utils/src/ooinstall/cli_installer.py @@ -106,8 +106,7 @@ http://docs.openshift.com/enterprise/latest/architecture/infrastructure_componen num_masters = 0 while more_hosts: host_props = {} - host_props['connect_to'] = click.prompt('Enter hostname or IP address:', - default='', + host_props['connect_to'] = click.prompt('Enter hostname or IP address', value_proc=validate_prompt_hostname) if not masters_set: @@ -144,13 +143,17 @@ http://docs.openshift.com/enterprise/latest/architecture/infrastructure_componen more_hosts = click.confirm('Do you want to add additional hosts?') if num_masters > 1: - hosts.append(collect_master_lb()) + collect_master_lb(hosts) return hosts -def collect_master_lb(): +def collect_master_lb(hosts): """ - Get an HA proxy from the user + Get a valid load balancer from the user and append it to the list of + hosts. + + Ensure user does not specify a system already used as a master/node as + this is an invalid configuration.
