Description of problem: Docker healthcheck works by checking for index.html in ODL. However, netvirt-ui feature which offers this URL was removed from Oxygen build. In order to fix the problem, we can load the dlux gui feature instead (odl-dlux-core).

Can we change how the docker healthcheck works? If not, is there another way we can get the index.html to show up without installing dlux? that project is pretty stale and maybe slated for removal. It'd be nice not to have to load it.
Patch merged into upstream queens
There is a REST endpoint we can use that seems like a better option than using the presence of that index.html file. we can hit this: curl -u "admin:admin" http://${ODL_IP}:8081/jolokia/read/org.opendaylight.infrautils:type=ready,name=SystemState The response is something like this: {"request":{"mbean":"org.opendaylight.infrautils:name=SystemState,type=ready","type":"read"},"value":{"SystemState":"ACTIVE"},"timestamp":1521496065,"status":200} notice the SystemState:ACTIVE. This would require the odl-infrautils-ready feature to be installed.
Lowering severity on this as unhealthy containers do not fail deployments. See https://bugs.launchpad.net/tripleo/+bug/1752925
Created attachment 1419132 [details] Feature list
Checked with openstack-tripleo-heat-templates-8.0.2-0.20180327213843.f25e2d8.el7ost.noarch I don't see the feature odl-dlux-core (I attached the features list). Also the container in unhealthy.
I am seeing unhealthy status too. I suspect it has something to do with jolokia or some config somewhere. $ curl http://10.10.125.12:8081/index.html <html> <head> <meta http-equiv="Content-Type" content="text/html;charset=utf-8"/> <title>Error 401 Unauthorized</title> </head> <body><h2>HTTP ERROR 401</h2> <p>Problem accessing /index.html. Reason: <pre> Unauthorized</pre></p> </body> </html> "Unauthorised" reason is weird too. $ curl -u admin:admin http://10.10.125.12:8081/index.html <html> <head> <meta http-equiv="Content-Type" content="text/html;charset=utf-8"/> <title>Error 404 Not Found</title> </head> <body><h2>HTTP ERROR 404</h2> <p>Problem accessing /index.html. Reason: <pre> Not Found</pre></p> </body> </html>

We moved to using index.html because it doesnot need (atleast when it was implemented) credentails. TripleO can provide custom credentials and no proper way was found to get credentials from any file in ODL.
Agreed that re-packaging DLUX again is not the way we want to go IMHO... Let us instead first clarify what we really want to check for, and then change the health check to probe something better than that /index.html? FYI that always was fairly useless, anyway (the fact that HTTP GET /index.html returns HTTP never really proved anything; just Karaf is running, but netvirt et al can be completely broken).
Let's decide what should be the way to do this check. For now I propose to curl the /controller/nb/v2/neutron path and see that it returns a non-error code (currently from what I see you get a 302 Found code). We can consider better alternatives for future versions but I suggest we track it in a different BZ.
Agreed, lets use /controller/nb/v2/neutron for the short term, and improve it later in bug 1566080.
