This commit adds a new flag --detail to etcdctl user get command. The
flag enables printing the detailed permission information of the user
like below example:
$ ETCDCTL_API=3 bin/etcdctl --user root:p user get u1
User: u1
Roles: r1 r2
$ ETCDCTL_API=3 bin/etcdctl --user root:p user get u1 --detail
User: u1
Role r1
KV Read:
[k1, k5)
KV Write:
[k1, k5)
Role r2
KV Read:
a
b
[k8, k9)
KV Write:
a
b
[k8, k9)
Currently the user can't list only the keys in a prefix search. In
order to support such operations the filtering will be done on the
server side to reduce the encoding and network transfer costs.
This commit expands RPCs for getting user and role and support list up
all users and roles. etcdctl v3 is now support getting all users and
roles with the newly added option --all e.g. etcdctl user get --all
This commit adds a feature for granting and revoking range of keys,
not a single key.
Example:
$ ETCDCTL_API=3 bin/etcdctl role grant r1 readwrite k1 k3
Role r1 updated
$ ETCDCTL_API=3 bin/etcdctl role get r1
Role r1
KV Read:
[a, b)
[k1, k3)
[k2, k4)
KV Write:
[a, b)
[k1, k3)
[k2, k4)
$ ETCDCTL_API=3 bin/etcdctl --user u1:p get k1 k4
k1
v1
$ ETCDCTL_API=3 bin/etcdctl --user u1:p get k1 k5
Error: etcdserver: permission denied
This commit implements RoleGet() RPC of etcdserver and adds a new
subcommand "role get" to etcdctl v3. It will list up permissions that
are granted to a given role.
$ ETCDCTL_API=3 bin/etcdctl role get r1
Role r1
KV Read:

This commit adds a new subcommand "user get" to etcdctl v3. It will
list up roles that are granted to a given user.
Example:
$ ETCDCTL_API=3 bin/etcdctl user get u1
User: u1
Roles: r1 r2 r3
This commit also modifies the layout of InternalRaftRequest for
frequent update of auth related members.
Migrate command accepts a datadir and an optional user-provided
transformer function that transform v2 keys to v2 keys.
Migrate command then builds a v3 backend state based on the existing
v2 keys and the output of the transformer function.
This commit adds a functionality of attaching an auth token to gRPC
connection as a per RPC credential.
For doing this, this commit lets clientv3.Client.Dial() create a
dedicated gRPC connection for doing authentication. With the dedicated
connection, the client calls Authenticate() RPC and obtain its
token. The token is attached to the main gRPC connection with
grpc.WithPerRPCCredentials().
This commit also adds a new option --username to etcdctl (v3). With
this option, etcdctl attaches its auth token to the main gRPC
connection (currently it is not used at all).
