Keycloak

Chat with Leo and Jon to review timing and req

Development

• merge Keycloak update (Song & Score) (Blocker Document) (keycloack integration (song), keycloack permission manager (Score)
• Generate Jar file for Keycloak Oveture APIkey extension (Leo: Devops will be in charge of pipelines. Yelizar working on this)

Documentation

• update score user docs with Keycloak UI permissions, scopes, and policies
• update score dev doc (more below)
• Update song user docs
• Song dev doc setup (Leo)
• update song docs with Keycloak information (plus ES, kafka and zookeeper)

We want to document Keycloak integration instructions within the score and song developer docs; this will be used to inform updates to the overture.bio user docs.

We will want to include:

• Setting up the developer environment (standalone and docker environment) (Leo: working on this)
• Integrating Keycloak (consider dev and production configurations) (Leo: working on this)

We will draft the docs within a Google Docs located here: https://docs.google.com/document/d/1J6ERQBItMPP8hJfFqa_EqD0-JmzXdiOvoBZ1whPAkc4/edit
