I've created a small example set of code to generate and learn about JWTs .  This code allows you to create and sign your own JWT.  You can create your own public/private keys to sign and verify the tokens. In and of itself this code would not likely be used for a production environment but knowing how a JWT works and the part of it are an important part of understanding Oauth2 in general.  I've got some future code to show you how to use a JWT in more of a production environment but this is useful to learn from.   Photo by Maick Maciel on Unsplash

  I've been using  Keycloak  for years now and have been experimenting with the newer versions that are based on top of  Quarkus .  One of the struggles I've had is spinning up a test server for development.  The new Quarkus model though is pretty simple.  A small  Docker Compose  script let's you spin up an environment in almost no time. My script looks like: version: '3.8' services: postgres: image: postgres:latest environment: POSTGRES_PASSWORD: ${POSTGRES_PASSWORD} restart: unless-stopped healthcheck: test: [ "CMD-SHELL", "pg_isready -U postgres" ] networks: - pg_network volumes: - ./pgdata:/var/lib/postgresql/data - ./create_db.sql:/docker-entrypoint-initdb.d/create_db.sql keycloak: image: quay.io/keycloak/keycloak:latest depends_on: postgres: condition: service_healthy environment: KC_DB: ${KC_DB} KC_DB_URL: ${KC_DB_URL} KC_DB_USERNAM
