mu-docker-compose-handler

Microservice to download the docker-compose.yml from a given repository's URL and store it in a graph database. It will create the DockerCompose model and link the current Stack to it. There are two entry points of this service:

1. /createdrc: In a scenario without a delta service, the frontend can call the service directly.
   • method: POST
   • payload: { 'uuid': <uuid> }
2. /update: This is the entrypoint for updates coming from the delta service. In order for the delta service to call this entrypoint we will need to edit the subscribers.json file like this:

{
  "potentials": [
  ],
  "effectives": [
    "http://drc-handler/update"
  ]
}

Workflow Diagram

Quick start

docker run -it --rm \
    --link database:some_container \
    -v /var/run/docker.sock:/var/run/docker.sock \
    mu-docker-compose-handler
Overrides

The default graph can be overridden by passing the environment variable MU_APPLICATION_GRAPH to the container. The default SPARQL endpoint can be overridden by passing the environment variable MU_SPARQL_ENDPOINT to the container.

Usage

Add the image to the docker-compose.yml file:

  drc-handler:
    build: ./mu-docker-compose-handler
    depends_on:
      - database
    links:
      - database:database

And add links to the dispatcher & delta service to it.
