Securing thorntail service with KEYCLOAK

I see a lot of topics about this but it seems that all of them access KEYCLOAK with the same URL. Explanation. I try to set up a frontend+microservice secured by KC architecture.

See the drawing:

Simple architecture

Everything work well if keycloak (kc) is seen by everybody with the same url, that is for JS:

const keycloakURL = "http://test-kc-keycloak:8080/auth";

const keycloakParams = {
  url: keycloakURL,
  realm: "Test",
  clientId: "IHM"
};
const keycloak = Keycloak(keycloakParams);
...

For the service (project-default.yml):

thorntail:
  keycloak:
    secure-deployments:
      kc.war:
        auth-server-url: "http://test-kc-keycloak:8080/auth"
        realm: Test
        resource: service
        bearer-only: true
        ssl-required: external
  microprofile:
    jwtauth:
      realm: Test
      token:
        issuedBy: "http://test-kc-keycloak:8080/auth/realms/Test"


  logging:
    loggers:
      kc:
        level: DEBUG

See https://github.com/lbroque/test-kc

But in the real world, the frontend is in the dark side of the net while KC and the service is supposed to be in a protected environment. So the frontend see KC through a reverse proxy and a HTTPS scheme, while the service see it with an HTTP scheme.

As far as I can see, the service try to access KC with SSL:

meaning it tries with the https scheme, No? so I suppose it uses the URL found in the TOKEN sent by frontend which got it with the HTTPS scheme, because I configured my service (so it should use HTTP scheme):

thorntail:
  keycloak:
    secure-deployments:
      model4xxx.war:
        auth-server-url: "http://keycloak.hnr:9090/auth"
        realm: xxx
        resource: model4xxx
        bearer-only: true
        ssl-required: external
  microprofile:
    jwtauth:
      realm: xxx
      token:
        issuedBy: "http://keycloak.hnr:9090/auth/realms/xxxx"

Last point : KC is in a DOCKER container. I tried several combinations of env variables KEYCLOAK_FRONTEND_URL, KEYCLOAK_HOSTNAME. It doesn't seem to have any effect.

I think I didn't understand the purpose of auth-server-url. What the use if the information could be found in the token ????

I'm sure it is something very very obvious that I don't see or understood ... please help.

Solution

  • Champagne ! With this conf (project-defauls.yml) :

    thorntail:
  keycloak:
    secure-deployments:
      model4geo3d.war:
        auth-server-url: "http://keycloak.hnr:9090/auth"
        realm: xxxx
        resource: model4xxx
        bearer-only: true
        ssl-required: external
  microprofile:
    jwtauth:
      realm: xxx
      token:
        issuedBy: "https://keycloak.hnr/auth/realms/xxxx"

    And :

           - "KEYCLOAK_FRONTEND_URL=https://keycloak.hnr/auth/"
        - "PROXY_ADDRESS_FORWARDING=true"

    in docker-compose of the keycloak container (keycloak.environment)

    And 

    keytool -import -trustcacerts -keystore /etc/ssl/certs/java/cacerts -storepass 'changeit' -file /home/core/dota/keycloak.hnr.crt -alias keycloak

    in the container of the data service, it works great.

    2020-05-06 17:41:56,582 INFO  [org.keycloak.adapters.KeycloakDeployment] (default task-1) Loaded URLs from http://keycloak.hnr:9090/auth/realms/xxxx/.well-known/openid-configuration

    got a correct config that it could use :)

    Thanks to Xtreme Biker for his help and time.
