Doc Text:	Previously, an initial puppet run during provisioning could result in puppet errors. The initial puppet run is only done to exchange certificates and errors in other puppet actions are not fatal. As a result, this would lead to erroneous reports of failed deployments. This has been fixed by ignoring errors in the first puppet run. Now, deployments no longer fail erroneously.	Story Points:	---

Description Lars Kellogg-Stedman 2014-07-25 18:18:59 UTC

When installing the 'Neutron Networker' role on a system with multiple interfaces, it is likely that only the provisioning interface has an address assigned when the kickstart is running.

This means that Puppet manifests that rely on facts like "ipaddress_eth1" to determine the ip address of an interface will fail, leading to errors such as:

  Could not retrieve catalog from remote server: Error 400 on SERVER: Local ip for ovs agent must be set when tunneling is enabled at /etc/puppet/environments/production/modules/neutron/manifests/agents/ovs.pp:32 on node mac52540036b16c.localdomain


This error *only* manifests during kickstart, because once the system boots for real all the interfaces are brought up and the appropriate facts are available.

Unfortunately, the error that crops during kickstart causes the deployment to fail.  So there are two problems here:

- Should we bring up interfaces before running puppet?  Or should we simply not run puppet in the kickstart?

- Should errors cause the deployment to *stop*, or should the deployment remain active and waiting for a successful puppet run?  In which case, the puppet run after the system boots should correct the error and allow the deploy to continue.

s/likely/certain/

I have confirmed that during the kickstart install, only the provisioning interface has an address.

Comment 2 Lars Kellogg-Stedman 2014-07-29 00:44:01 UTC

pchalupa proposed the following patch:

diff --git a/app/lib/actions/staypuft/host/wait_until_host_ready.rb b/app/lib/actions/staypuft/host/wait_until_host_ready.rb
index 5fb3b86..8d755fb 100644
--- a/app/lib/actions/staypuft/host/wait_until_host_ready.rb
+++ b/app/lib/actions/staypuft/host/wait_until_host_ready.rb
 -59,7 +59,7 @@ module Actions
 
         def host_ready?(host_id)
           host = ::Host.find(host_id)
-          host.reports.order('reported_at DESC').any? do |report|
+          host.reports.order('reported_at DESC')[0..-2].any? do |report|
             check_for_failures(report, host.id)
             report_change?(report)
           end

This causes the workflow engine to ignore the first report from Puppet, so errors encountered during Kickstart are ignored.  I have tried this in my test environments and it appears to work as advertised.
