Usage: consul services deregister [options] [FILE...]
|
|
|
|
Deregister one or more services that were previously registered with
|
|
the local agent.
|
|
|
|
$ consul services deregister web.json db.json
|
|
|
|
The -id flag may be used to deregister a single service by ID:
|
|
|
|
$ consul services deregister -id=web
|
|
|
|
Services are deregistered from the local agent catalog. This command must
|
|
be run against the same agent where the service was registered.
