I've spent most of the day trying to configure the Fiware PEP proxy Wilma to secure an Orion Context Broker i have running on a development server. The documentation here: http://forge.fiware.org/plugins/mediawiki/wiki/fiware/index.php/PEP_Proxy_-Wilma-_Installation_and_Administration_Guide is not clear.
Here is my setup:
- A Fiware Keyrock instance running on server1, port 3000
- A PEP Proxy running on server 1
- An Orion Context Broker running on server2, port 1026
The manual states to edit the config.js script. Here is what i changed (Stackoverflow prevents me from entering url's so replace http.. with http:)
config.account_host = 'http..//localhost:3000';
config.keystone_host = 'http..//server1';
config.keystone_port = 3000;
config.app_host = 'server2';
config.app_port = '1026';
config.username = '***** username of the user in Keyrock *****';
config.password = '***** password of the user in Keyrock *****';
Here is the error
~/fi-ware-pep-proxy$ node server.js express deprecated app.configure: Check app.get('env') in an if statement server.js:30:5 Starting PEP proxy. Keystone authentication ... Error in keystone communication Error: getaddrinfo ENOTFOUND at errnoException (dns.js:37:11) at Object.onanswer [as oncomplete] (dns.js:124:16)
My Orion and Keyrock instances are up and running. I can query them with curl or a browser.
I really have no idea what i should be filling in the config.js to get this set up.
I hope this helps. We are working on deploying some of the Generic Enablers, included IdM, Wilma PEP and Orion among others using docker and docker-compose.
This environment, called Fiware-devguide-APP is actually under construction, but you can test's the environment (already working) and also check our configuration here.
We are updating all the documentation!
For this, we have the images here.
Docker and docker-compose are required.
If you already have them, to start all the apps integrated in Devguide, you just have to clone the repository:
git clone https://github.com/Bitergia/fiware-devguide-app.git
And then run docker-compose using the .yml
file in the fiware-devguide-app/docker/compose:
docker-compose -f docker-compose.yml up -d
So you will have up all the containers! Finally, add the ip of the devguide container (compose_devguide_1) to your /etc/hosts
and you will be able to browse it :)
Explanation:
We've went through several configurations for this. I assume you are interested in IdM and Wilma PEP, so here it goes what we did:
We've installed a IdM GE from the scratch providing the users, roles, and permissions desired. Here you can find what we added at
test_data
method:- We've added test users
- Couple organizations
- Our app
- Roles for the application
- And permissions for the actions
Note that all those provision could have been done also using Keystone REST API
Also here you can find the Dockerfile i.e. how it has been installed.
We've installed an Authzforce for the role management as explained in the tour guide. You will need it as wilma-pep will send the PDP requests to validate requests against the resource protected.
Finally the PEP Wilma. Here you can find the configuration files.
How does it work?
Here goes the trick. Let's assume the env Authzforce (Access Control), IdM, PEP Wilma, Orion (the app to be protected) and the devguide. As we use docker-compose, all this steps are done almost at the same time! :)
In authzforce, we need to create a domain as stands in the documentation, and we do it here.
The script itself retrieves the domain ID and, it parses the
config.js
file of the PEP Wilma in this line using the right path.The
config.js
is simple:account_host
andkeystone_host
are in the same container 'idm'. Docker-compose handle this by adding aliases to the/etc/hosts
of each container, which makes the process much easier and we don't need to handle the IP's ourselves.app_host
andapp_port
are the IP and port of the app to protect, in our case is 'orion'!config.username
andconfig.password
. We've created a user 'pepproxy' in the provision we explained before, exactly here. (Note that this user must havedomain roles
assigned in order to work, as done here).- And the
azf
configuration, which contains also the 'authzforce' host and where the path is parsed as explained before.
Adding the authzforce configuration to IdM and PEP (i.e. domain)
Get an Oauth2 token as it explains here.
Finally, with this token and everything running, you can open the
compose_devguide_1
. It has different resources that can be reached depending on the roles you have assigned at IdM. For example, 'user0@test.com' can access to all the resources, meanwhile the other one can access just to the restaurants.
Hope I was clear enough.
Best!
right now requests from PEPs are not directly sent to the IdM. They uses an Openstack compliant server (Keystone Proxy). So if you want to use it you have to install also this component. Any way in two weeks we are going to change this behaviour.
Hope this helps
We are installing a Fiware enviroment in a local machine; we pretend to have an orion context broker with a Keyrock idm instance. We understand that we need to use a Pep Proxy in order to check the tokens of the requests to the orion context broker. We use Keyrock idm, so we are wondering whether we can do this or not. Is there any way to use them now without installing anything else or we are supposed to install de keystone proxy too?
This is the keystone proxy that we have found:
https://github.com/ging/fi-ware-keystone-proxy
If this is the case; How do we have to configure the pep proxy? Where do we have to put the data to connect to the Keyrock idm and where are we supposed to indicate the keystone information?
new versions are ready. Now you only need Keyrock and PEP Proxy. As explained here validations go directly to IdM. Hope this helps.
