Error while opening cockpit

Question

I am trying to create a cockpit and this is my error. Is anyone is aware of this error?

{"service":"","errors":[{"message":"RESTEASY003210: Could not find resource for full path: http://34.193.191.224:8080/knowage/restful-services/undefined&SBI_ENVIRONMENT=WORKSPACE&IS_TECHNICAL_USER=false&DATASET_LABEL="}]}

Thanks in advance !

Please, write as much detail as possible. How did you installed Knowage? If it is a custom installation, which is your application server? Give more info.

I think I have the same problem.

I started knowage 6.1.1 and knowagedb from a docker-compose.yml file that's slightly modified from the one available on github. I modified it so the knowage app server would have access to the postgres database I'm testing with, also in a container. Here's the compose file

version: '2'

networks:
  default:
    external:
      name: app_under_test

services:
  knowage:
      image: knowagelabs/knowage-server-docker:6.1.1
      links:
          - knowagedb:db
      ports:
          - "8080:8080"
      environment:
          - WAIT_MYSQL=true
          # Need these manually set to be compatible docker-compose v1
          - DB_PORT_3306_TCP_ADDR=knowagedb
          - DB_PORT_3306_TCP_PORT=3306
          - DB_ENV_MYSQL_USER=knowageuser
          - DB_ENV_MYSQL_DATABASE=knowagedb
          - DB_ENV_MYSQL_PASSWORD=knowagepassword
      container_name: knowage

  knowagedb:
      image: mysql:5.5
      environment:
          - MYSQL_USER=knowageuser
          - MYSQL_PASSWORD=knowagepassword
          - MYSQL_DATABASE=knowagedb
          - MYSQL_ROOT_PASSWORD=knowagerootpassword
      container_name: knowagedb

I can login to the knowage web UI at http://localhost:8080/knowage/. Most pages are fine. Trying to create a 'New Cockpit' tries to download angular resources from the ip address of the container, not from the docker-exposed port on localhost.

Start on the Document Browser page. Hit the plus sign to add a new document. Pick a Cockpit type from the dropdown. Firefox's console mentions this

XML Parsing Error: not well-formed
Location: http://localhost:8080/knowagecockpitengine/js/src/messages/messages.properties
Line Number 1, Column 1:

while the browser is waiting trying to download from http://172.22.0.4:8080, which is the ip address of the knowage docker container.

Here's one example of a resource the browser is trying to download (via firefox's network panel)

http://172.22.0.4:8080/knowage/js/lib/angular/angular-json-tree/json-tree.js

Is there a configuration in knowage somewhere to set the front part of the url that it should use, instead of detecting the ip address of the host it's running on?

Browser is

Found a solution here

https://www.knowage-suite.com/qa/1788/adding-a-cockpit-blank-page-appear

In that post, the answer is to change TOMCAT_HOME/conf/server.xml and modify the host_url setting.

In the docker container version, TOMCAT_HOME/bin/entrypoint.sh sets this value every container start. It defaults the value to the ip address of the container, but that setting can be overridden by setting the environment varaible PUBLIC_ADDRESS to be 'localhost' in my case.

Here's the environment-variable section from above for the knowage container, with the new change

environment:
    - WAIT_MYSQL=true
    # Need these manually set to be compatible docker-compose v1
    - DB_PORT_3306_TCP_ADDR=knowagedb
    - DB_PORT_3306_TCP_PORT=3306
    - DB_ENV_MYSQL_USER=knowageuser
    - DB_ENV_MYSQL_DATABASE=knowagedb
    - DB_ENV_MYSQL_PASSWORD=knowagepassword
    - PUBLIC_ADDRESS=localhost
container_name: knowage

Now on my mac, knowage loads the cockpit from localhost:8080 instead of 172.22.0.4.
