This page contains information, code snippets and other information regarding using Keycloak with mod_auth_openidc.

Running on Azure

HEE fork of Keycloak repository;

https://github.com/Health-Education-England/keycloak

The code for the HEE Docker container is here;

...

There is a Jenkins job that will rebuild the Keyclock Docker image;

https://build-hee.tis.transformcloudnhs.netuk/jenkins/job/keycloak-docker/

When this job completes, docker-compose runs to restart the stack on the dev server;

https://build-hee.tis.transformcloudnhs.netuk/jenkins/job/keycloak-dev-deploy/

The service should then be available at this address;

https://dev-apps.lintis.nhs.uk/auth/

Running locally

Keycloak is available from keycloak.org.  It is an application embedded in a JBoss WildFly JEE container.  The easiest way to get it working is to use an existing docker container.  This container is set up to use with a MySQL datastore.  To run Keycloak with a dockerized version of MySQL

1. Run MySQL, if you don't have a local MySQL server running then you can create one with the following commands;

   Code Block
   $ docker run --name mysql -e MYSQL_DATABASE=keycloak -e MYSQL_USER=keycloak -e MYSQL_PASSWORD=29UTYZ735L0T8i7h6657Di71H -e MYSQL_ROOT_PASSWORD=password -d mysql

   
   

2. If you want to create a database in an existing instead MySQL database then try the following; 

   Code Block
   create database keycloak; grant all on keycloak.* to keycloak@'%' identified by '29UTYZ735L0T8i7h6657Di71H'; flush privileges;

   
   

3. Add a DNS entry in your /etc/hosts file pointing to mysql.lintis.nhs.uk  where aaa.bbb.ccc.ddd is the IP address that your MySQL server is listening on.

   Code Block
   $ echo "aaa.bbb.ccc.ddd mysql.lintis.nhs.uk " >> /etc/hosts

   
   

4. Start Keycloak using the docker-compose file for the stack https://github.com/Health-Education-England/TIS-DEVOPS/blob/master/docker/stacks/keycloak/docker-compose.yml 

   Code Block
   $ cd $TIS-DEVOPS/docker/stacks/keycloak $ docker-compose up -d

Programmatic Access

The following script show how a JWT token can be To access an API programmatically, a new Keycloak user needs to be added to the LIN realm. The username and password can then be exchanged for a JWT token to make a request to a protected service. The following script show how a JWT token can be acquired and how that token is used to make an authenticated request, in this case, our jamesh user;

#! /bin/bash

# Step3Step 1
export TOKEN=$(curl -s 'https://dev-apps.lintis.nhs.uk/auth/realms/lin/protocol/openid-connect/token' \
  -d "client_id=adminapi-clitokens&username=jamesh&password=j4m3srul3z&grant_type=password" | jq -r .access_token)

# Step 2 - optional
curl https://dev-apps.lintis.nhs.uk/auth/realms/lin/protocol/openid-connect/token/introspect \
	-d client_id=<client id> \
	-d client_secret=<client secret> \
	-d "token=${TOKEN}" \
	| python -m json.tool

# Step 3
curl -i -H "Authorization: bearer ${TOKEN}" \
 	https://dev-apps.lintis.nhs.uk/api/revalidation/health 

1. Use use a password grant to exchange a username and password for a JWT token. The response from this command will be a JSON document with the access token with it;

   Code Block
   { "access_token": "<long string value>", "expires_in": 300, "id_token": "<long string value>", "not-before-policy": 0, "refresh_expires_in": 1800, "refresh_token": "<long string value>", "session_state": "<uuid>", "token_type": "bearer" }

2. In this step, we show how the token is validated using a client id and secret. This step will be completed by mod_auth_openidc and is included for completeness.
3. In this step, we add the "Authorization: Bearer <access token>" header to our call. Apache will intercept the call, extract the JWT and validate it before forwarding the request to the target API.

LIN Keycloak Theme

We have updated the Keycloak theme for the login screens, the new code is held in https://github.com/Health-Education-England/TIS-KEYCLOAK-THEME

To update the theme, the customised Docker image needs to be updated to include that code. There is a job to rebuild in Jenkins https://build-hee.transformcloud.net/jenkins/job/keycloak-docker/NB for testing and debugging locally, use a token generated using:

curl -s 'https://dev-apps.tis.nhs.uk/auth/realms/lin/protocol/openid-connect/token'  -d "client_id=api-tokens&username=jamesh&password=j4m3srul3z&grant_type=password" | jq -r .access_token

Or

curl -s 'http://localhost:8087/auth/realms/lin/protocol/openid-connect/token' -d "client_id=api-tokens&username=jamesh&password=j4m3srul3z&grant_type=password" | jq -r .access_token

Note: the client_id = api-tokens. This will bring back user roles etc

1. Use use a password grant to exchange a username and password for a JWT token. The response from this command will be a JSON document with the access token with it;

   Code Block
   { "access_token": "<long string value>", "expires_in": 300, "id_token": "<long string value>", "not-before-policy": 0, "refresh_expires_in": 1800, "refresh_token": "<long string value>", "session_state": "<uuid>", "token_type": "bearer" }

   
   

2. In this step, we show how the token is validated using a client id and secret. This step will be completed by mod_auth_openidc and is included for completeness.

3. In this step, we add the "Authorization: Bearer <access token>" header to our call. Apache will intercept the call, extract the JWT and validate it before forwarding the request to the target API.

Styling updates to keycloak theme

It is possible to tweak the styling for a keycloak theme without having to run keycloak locally via using charles https://www.charlesproxy.com/download/ which is a web proxy application. This is achieved by locally mapping the remote css file responsible for the theme to a local css file on your computer. 

For example the remote css file https://stage-apps.tis.nhs.uk/auth/resources/2.2.2.final-snapshot/login/lin/css/login.css can be mapped to /Users/XXX/Sites/HEE/keycloak/themes/lin/login/resources/css/login.css which essentially means you can locally work on the css and once done can push your changes to the git repo mentioned above as well as triggering the jenkins job https://build-hee.transformcloud.net/jenkins/job/keycloak-dev-deploy/

Steps to map a remote file locally

1. Enable SSL proxing for the host
