I’m using Consul, with Nomad, all with ACL enabled. I have a service with 3 instances, and would like to manually update tags on specific instances (1 instance master, 2 instances replica). But I do not understand how to do this. I know I have to use the API, there’s no easy way to do it with consul cli. But what I want is simply
- Get the current service definition
- Add / Remove the tags I need
- Register the service again to update the tags, without changing anything else
I really do not understand how to do this. There’re several API endpointsto both get, or set/modify servcices
Could anyone provide a simple one-liner to update the service tag while keeping everything else the same ?
