Keycloak integration with RadosGW
|
|
=================================
|
|
|
|
Keycloak can be setup as an OpenID Connect Identity Provider, which can be used by mobile/ web apps
|
|
to authenticate their users. The Web token returned as a result of authentication can be used by the
|
|
mobile/ web app to call AssumeRoleWithWebIdentity to get back a set of temporary S3 credentials,
|
|
which can be used by the app to make S3 calls.
|
|
|
|
Setting up Keycloak
|
|
====================
|
|
|
|
Installing and bringing up Keycloak can be found here: https://www.keycloak.org/docs/latest/server_installation/.
|
|
|
|
Configuring Keycloak to talk to RGW
|
|
===================================
|
|
|
|
The following configurables have to be added for RGW to talk to Keycloak.
|
|
The format of token inspection url is https://[base-server-url]/token/introspect::
|
|
|
|
[client.radosgw.gateway]
|
|
rgw sts key = {sts key for encrypting/ decrypting the session token}
|
|
rgw s3 auth use sts = true
|
|
|

Example showing how to fetch a web token from Keycloak
|
|
======================================================
|
|
|
|
Several examples of apps authenticating with Keycloak are given here: https://github.com/keycloak/keycloak-quickstarts/blob/latest/docs/getting-started.md
|
|
Taking the example of app-profile-jee-jsp app given in the link above, its client secret and client password, can be used to fetch the
|
|
access token (web token) as given below::
|
|
|
|
KC_REALM=demo
|
|
KC_CLIENT=<client id>
|
|
KC_CLIENT_SECRET=<client secret>
|
|
KC_SERVER=<host>:8080
|
|
KC_CONTEXT=auth
|
|
|
|
# Request Tokens for credentials
|
|
KC_RESPONSE=$( \
|
|
curl -k -v -X POST \
|
|
-H "Content-Type: application/x-www-form-urlencoded" \
|
|
-d "scope=openid" \
|
|
-d "grant_type=client_credentials" \
|
|
-d "client_id=$KC_CLIENT" \
|
|
-d "client_secret=$KC_CLIENT_SECRET" \
|
|
"http://$KC_SERVER/$KC_CONTEXT/realms/$KC_REALM/protocol/openid-connect/token" \
|
|
| jq .
|
|
)
|
|
|
|
KC_ACCESS_TOKEN=$(echo $KC_RESPONSE| jq -r .access_token)
|
|
|
|
KC_ACCESS_TOKEN can be used to invoke AssumeRoleWithWebIdentity as given in
|
|
:doc:`STS`.
