### `mode`
Two modes of service discovery are supported: `node` and `service`. `node`, the default will register a service using
the `/v1/catalog` endpoints and mTLS (if `client_cert` and `client_key` are provided). `service` mode uses the
`v1/agent` endpoints instead, where an optional `consul_http_token` may be provided.
### `consul_http_addr` and `service_name` ### `consul_http_addr` and `service_name`
The `consul_http_addr` parameter should be set to the full HTTP(S) address of the Consul server. The `consul_http_addr` parameter should be set to the full HTTP(S) address of the Consul server.

`service` mode only. Uses the provided token for communication with Consul. The policy assigned to this token
should at least have these rules:
