Kie server router always response 404

[Александр Емельянов]

HI!

I have jbpm 7.7.0 instalation. In kie execution server configuration I add property:

-Dorg.kie.server.router=http://<local ip>:9000

Kie server router has next configuration:

-Dfile.encoding=UTF-8 -XX:+UseG1GC \

-Dorg.kie.server.router.host=0.0.0.0 \

-Dorg.kie.server.router.port=9000 \

-Dorg.kie.server.router.url.external=http://localhost:9000/ \

-Dorg.kie.server.controller=http://localhost:8082/kie-wb/rest/controller \

-Dorg.kie.server.controller.user=... \

-Dorg.kie.server.controller.pwd=... \

In kie workbench UI appeared KIE Server Router configuration with one remote server and I can deploy container there, but kie-wb can not do anything with router.

Kie router always answer 404 for any request, i.e.

wget --quiet \

  --method GET \

  --header 'Accept: application/json' \

  --header 'Authorization: Basic ...' \

  --header 'Cache-Control: no-cache' \

  --output-document \

  - http://localhost:9000/containers

what I do wrong?

Could you provide exact commands you use for starting:

- router

- workbench

- kie server

Have a look at this article as it might become helpful http://mswiderski.blogspot.com/2017/01/kie-server-router-integrated-with.html

Maciej, can I found relevant documentation for kie router anywhere?

Does it have any rest documentation? i.e. swagger?

Router itself has very tiny rest (like) api that consists fo three endpoints:

- /mgmt/list - list all configuration it has in terms for kie servers and their containers

- /mgmt/add - adds new kie server/container info

- /mgmt/remove - remove kieserver/container info

Other than that it mirrors KIE Server’s REST api - main difference it does not allow to use KIE Server management api - meaning create/dispose KIE containers. Other than that it should expose (forward) all other endpoints. There is no swagger docs for router itself as the same endpoints will be in KIE Server swagger docs.

Yes, /mgmt/list woks. But workbench have 404 errors in log:

Maybe this is authentication issue - router might then simply return page not found - workbench uses kieserver/kieserver1! As default credentials so double check if you have these setup on kie servers behind router.

I check password configuration. All is OK. Also I try to use default credentials - there no effect, error occurs again

Turn on debug logs for org.kie.server package on workbench server, that might give us some more information what’s happening.
