Description of problem:

Ref: https://openshift.redhat.com/community/faq/can-i-access-my-applications-gear

I have used haproxy_ctld -u to launch a new gear in manual mode. haproxy_ctld_daemon was not and is not running. Using rhc app show, I saw Scaling: go from 1 to 2 as expected. However, ~/haproxy-1.4/conf/gear-registry.db is empty. Where else can I find the IP or host of the framework gear?

Version-Release number of selected component (if applicable):

Can't reproduce this issue on devenv or int.

[rmtest-rmillnerint.int.rhcloud.com 51378bb36cec0e896a00007d]\> haproxy_ctld -u
[rmtest-rmillnerint.int.rhcloud.com 51378bb36cec0e896a00007d]\> cat ~/haproxy-1.4/conf/gear-registry.db

Taking off the build blocker list.

The haproxy_ctld daemon should be running; but you can disable auto_scaling by setting the appropriate marker.

Here's how to do that:

Go into your git clone of the application
touch .openshift/markers/disable_auto_scaling
git add .openshift/markers/disable_auto_scaling
git commit -m 'Disabled automatic scaling'
git push

Then ssh back into your head gear, scale up and observe ~/haproxy-1.4/conf/gear-registry.db.

Try this bug in two ways,

One is Rob mentioned, after haproxy_ctld -u, gear info recorded into gear_registry.db

The other one, is kill the haproxy_ctld manually, then haproxy_ctld -u,
\> ps -ef |grep haproxy_ctld
501      2142     1  0 21:33 ?        00:00:00 haproxy_ctld.rb                                                                                  
501      23470 23012  0 21:41 pts/1    00:00:00 grep haproxy_ctld                                                             
\> kill -9 2142
\> cat haproxy-1.4/conf/gear-registry.db
\> haproxy_ctld -u
\> cat haproxy-1.4/conf/gear-registry.db
\> ps -ef |grep haproxy_ctld
501      13941     1  0 21:45 ?        00:00:00 haproxy_ctld.rb                                                                                  
501      24985 23012  0 21:45 pts/1    00:00:00 grep haproxy_ctld

One concern of the issue in topic is, the haproxy_ctld -u took a long time,and the gear which just scaled-up has already scaled-down automatically.

Please add disable_auto_scaling marker to prevent this kind of problem. As comment#2.  Thanks.
