I am a bit of a noob to curl/REST, and have looked but can't find much that makes sense to me.
am playing with etcd, storing some keys, i can use etcdctl to pull a single return, which is very handy, as I intend to echo such things into config files;
etcdctl get /dtank/facts/server/IP
10.2.0.91
which is ace. what I'm trying to do now is get that same functionality via curl, as I will need to make such requests on machines that do not have etcdctl installed.
when I run the following;
I get this;
{"action":"get","node":{"key":"/dtank/facts/server/IP","value":"10.2.0.91","modifiedIndex":19,"createdIndex":19}}
My question here is really, do I need to jump through hoops [grep, sed, etc] to resolve this return down to the IP address, which is what I'm after, or is there some trick I can use to request just that value?
many many thanks in advance!
