Unable to find Kubernetes apiserver's data in etcd3
To get keys and values stored in etcd v3 by kubernetes:
ETCDCTL_API=3 etcdctl --endpoints=http://localhost:2379 get --prefix /registryTo get 1 specified key and value from etcd v3, e.g.:
ETCDCTL_API=3 etcdctl --endpoints=http://localhost:2379 get /registry/services/specs/default/kubernetesBased on: https://github.com/coreos/etcd/blob/master/Documentation/dev-guide/interacting_v3.md
If your system is set up correctly be aware that there are some changes from etcd2 to etcd3. For example the key space in etcd3 is now flat so unlike etcd2 there are no longer any directories. Instead of using the etcdctl 'ls' command as shown above use the 'get' command instead (and make sure the etcdctl command is using the v3 api by having the ETCDCTL_API=3 environment variable set).
