sample post-hook to upload-to-horreum needs to be fixed

[rafaeltuelho]

I noticed the Operator generates a ConfigMap containing a sample post-hook that can be used to upload reports to Horreum using its API.

horreum-operator/controllers/horreum_controller.go

Lines 539 to 545 in 104e3a4

	TOKEN=$(curl -s -X POST ` + keycloakURL + `/auth/realms/horreum/protocol/openid-connect/token ` +
	` -H 'content-type: application/x-www-form-urlencoded' ` +
	` -d 'username='$HORREUM_USER'&password='$HORREUM_PASSWORD'&grant_type=password&client_id=horreum-ui'` +
	` | jq -r .access_token)
	curl -s '` + horreumURL + `/api/run/data?owner='$HORREUM_GROUP'&access=PUBLIC&test=$.info.benchmark&start=$.info.startTime&stop=$.info.terminateTime'` +
	` -X POST -H 'content-type: application/json' -d @$RUN_DIR/all.json -H 'Authorization: Bearer '$TOKEN

This sample post-hook needs some tweaks in order to work properly like the curl command used to retrieve a OIDC Token from keycloak needs to include the -k option in case of self-signed certs...
The other thing is to fix the OIDC token api URL from

/auth/realms/horreum/protocol/openid-connect/token

to

/realms/horreum/protocol/openid-connect/token

and also include the $RUN_ID to the json file path

-d @$RUN_DIR/$RUN_DIR/all.json
