This setup is intended for local development.

Here is a diagram of the template layout

Backing services

• cache/key-value: Redis
• database server: (Mysql)
• Queue: rabbitMq
• Auth Server: Keycloak

We will be using docker to generate our backing services

$ cd backing-services
$ docker-compose [build|start]

If all goes well we should have all our backing services up and running.

We only need to setup our keycloak server, we need to:

• create realm: "sbService"
• create a client: "sb-service-edge" , get client secret from keycloak and update edge application.yml
• create a couple of realm roles: sbAdmin, sbUser1, sbUser2
• create a couple of users: sbadmin, sbuser1, sbuser2 and link to corresponding roles.

Available endpoints:

• GET ../service-a (public)
• GET ../service-a/auth-user1 (private)
• GET ../service-a/auth-user2 (private)

--

• GET ../service-b (public)
• GET ../service-b/auth-user1 (private)
• GET ../service-b/auth-user2 (private)

--

• GET ../service-c (public)

• GET ../service-c/auth-user1 (private)

• GET ../service-c/auth-user2 (private)

• POST../service-c/queue-job (any authenticated user)

request:

{
    "jobType": "...",
    "jobData": [
        {
            "key": "...",
            "value": "..."
        }
    ]
}
