Differences between conf and topologies
Hi,
What are the main differences between "conf/gateway-site.xml",
"topologies/manager.xml" and "topologies/admin.xml"?
I'm still trying to understand how all work together in Knox.
Per example, I can see there's a section for LDAP configuration on
"topologies/admin.xml" but also as part of "conf/gateway-site.xml". Which
one affects what exactly?
Thanks

No. Anything in gateway-site.xml is basically there as defaults and can be
referenced from topologies. Any topology can be configured independently of
what is in gateway-site.xml. Changes in manager.xml would be preferred over
what is in gateway-site if they are topology specific.

Thanks Kevin,
So, does it mean that gateway-site.xml o overwrites any configuration set
as part of manager.xml?
Thanks

The UI configuration comes from "topologies/manager.xml". If you look at
the manager.xml, it can reference configurations in the global
"conf/gateway-site.xml" if it wants to. Topologies don't need to though.
You could technically move the group config stuff from
"conf/gateway-site.xml" to the manager.xml file.
The example topologies that ship with Knox show that it is possible to
configure some settings in "conf/gateway-site.xml" but it is not necessary.
The example is one you already referenced which is the group lookup:
*
https://github.com/apache/knox/blob/master/gateway-release/home/conf/gateway-site.xml#L94
*
https://github.com/apache/knox/blob/master/gateway-release/home/conf/topologies/manager.xml#L60

Hi Kevin,
Thank for the clarification.
What do you mean by "One of those is the group configurations"? Would be
possible to provide an example?
Based on your comment, does it mean the LDAP configuration to access the UI
comes from "conf/gateway-site.xml"?
Thanks!

"conf/gateway-site.xml" has configurations that are global to the entire
Knox instance.
"topologies/abc.xml" are configurations specific to the topology. The
topologies can reference some configurations in the global
"conf/gateway-site.xml". One of those is the group configurations. This
would be useful to say have multiple topologies not have to repeat the same
configuration over and over again. On the other hand, you can so choose to
duplicate the configuration in each topology.
