Swarmeta

Swarmeta is a metadata service discovery for docker swarm. Services can be queried by arbitrary labels. The responses are rendered as predefined views.

Configuration

docker_socket = "unix:///var/run/docker.sock"

view "@default" {
    metadata "name" {
        template = "{{.Spec.Name}}"
        OmitEmpty = true
    }
    metadata "id" {
        template = "{{.ID}}"
    }
    metadata "last_update" {
        template = "{{.UpdatedAt}}"
    }
}

To get a complete list of properties you can use in the metadata templates see: https://godoc.org/github.com/docker/docker/api/types/swarm#Service

Query

Just send a request to /api/v1/find/ all query parameters are interpreted as swarm service label matches. To get an EventStream (SSE) append ?_follow=true. To select another view as @default you can set the query parameter ?_view=<viewname>.
