OAUTH BLOCK

Devenv setup oauth

To launch the block, use the oauth source. Ex:

make devenv sources="oauth"

Here is the conf you need to add to your configuration file (conf/custom.ini):

[auth]
signout_redirect_url = http://localhost:8087/auth/realms/grafana/protocol/openid-connect/logout?redirect_uri=http%3A%2F%2Flocalhost%3A3000%2Flogin

[auth.generic_oauth]
enabled = true
name = Keycloak-OAuth
allow_sign_up = true
client_id = grafana-oauth
client_secret = d17b9ea9-bcb1-43d2-b132-d339e55872a8
empty_scopes = true
email_attribute_path = email
login_attribute_path = login
name_attribute_path = name
auth_url = http://localhost:8087/auth/realms/grafana/protocol/openid-connect/auth
token_url = http://localhost:8087/auth/realms/grafana/protocol/openid-connect/token
api_url = http://localhost:8087/auth/realms/grafana/protocol/openid-connect/userinfo
role_attribute_path = contains(roles[*], 'admin') && 'Admin' || contains(roles[*], 'editor') && 'Editor' || 'Viewer'

Devenv setup jwt auth

To launch the block, use the oauth source. Ex:

make devenv sources="oauth"

Here is the conf you need to add to your configuration file (conf/custom.ini):

[auth.jwt]
enabled = true
header_name = X-JWT-Assertion
username_claim = login
email_claim = email
jwk_set_file = devenv/docker/blocks/oauth/jwks.json
cache_ttl = 60m
expected_claims = {"iss": "http://localhost:8087/auth/realms/grafana", "azp": "grafana-oauth"}
auto_sign_up = true

You can obtain a jwt token by using the following command for oauth-admin:

curl --request POST \
  --url http://localhost:8087/auth/realms/grafana/protocol/openid-connect/token \
  --header 'Content-Type: application/x-www-form-urlencoded' \
  --data client_id=grafana-oauth \
  --data grant_type=password \
  --data client_secret=d17b9ea9-bcb1-43d2-b132-d339e55872a8 \
  --data scope=openid \
  --data username=oauth-admin \
  --data password=grafana

Grafana call example:

curl --request GET \
  --url http://127.0.0.1:3000/api/folders \
  --header 'Accept: application/json' \
  --header 'X-JWT-Assertion: eyJ......'

Alternative devenv setup jwk_set_url

Run a reverse proxy pointing to the jwk_set_url (only an https-uri can be used as jwk_set_url).

Ex (using localtunnel):

npx localtunnel --port 8087

And using the following conf:

[auth.jwt]
enabled = true
header_name = X-JWT-Assertion
username_claim = login
email_claim = email
jwk_set_url = <YOUR REVERSE PROXY URL>/auth/realms/grafana/protocol/openid-connect/certs
cache_ttl = 60m
expected_claims = {"iss": "http://localhost:8087/auth/realms/grafana", "azp": "grafana-oauth"}
auto_sign_up = true

Backing up keycloak DB

In case you want to make changes to the devenv setup, you can dump keycloack's DB:

cd devenv;
docker-compose exec -T oauthkeycloakdb bash -c "pg_dump -U keycloak keycloak" > docker/blocks/oauth/cloak.sql

Connecting to keycloack:

• keycloak admin: http://localhost:8087
• keycloak admin login: admin:admin
• grafana oauth viewer login: oauth-viewer:grafana
• grafana oauth editor login: oauth-editor:grafana
• grafana oauth admin login: oauth-admin:grafana

Troubleshooting

Mac M1 Users

The new arm64 architecture does not build for the latest docker image of keycloack. Refer to https://github.com/docker/for-mac/issues/5310 for the issue to see if it resolved. Until then you need to build the docker image locally and then run devenv.

1. Remove any lingering keycloack image

$ docker rmi $(docker images | grep 'keycloack')

1. Build keycloack image locally

$ ./docker-build-keycloack-m1-image.sh

1. Start from beginning of this readme
