How to auto deregister a service?

[Ha Truong]

I have a service registered to Consul. When I turn it off, how can I auto deregister? Is it a config when register?

[Nicholas Capo]

You could use the http api [1] to deregister it, but probably only if you used the api to do the registration too, instead of the config file.

Isn't that what a health check does?  Maybe I'm being naïve.  I'm going to need to figure this out soon too.  Will try to remember to post an update once I get there.

Health checks and service registrations are independent of each other in Consul. They work closely together, but it is not strictly necessary that you deregister a service if the node(s) providing the service go offline. Queries via the DNS or HTTP health API's will not return the unhealthy node when querying for the service. If you want to completely deregister the service, then you can do so by removing the service from the config, or using the HTTP API if you registered the service that way.

Hope that helps!
