Usage: consul services register [options] [FILE...]
|
|
|
|
Register one or more services using the local agent API. Services can
|
|
be registered from standard Consul configuration files (HCL or JSON) or
|
|
using flags. The service is registered and the command returns. The caller
|
|
must remember to call "consul services deregister" or a similar API to
|
|
deregister the service when complete.
|
|
|
|
$ consul services register web.json
|
|
|
|
Additional flags and more advanced use cases are detailed below.
