可以用以下命令为用户添加所有的caps，拥有对应的cap的用户可以操作不仅限与属于用户自己的桶和对象和其他用户，可以看作拥有管理员的某种权限

radosgw-admin caps add --uid=admin --caps="users=*;buckets=*;metadata=*;usage=*;zone=*"

*代表read和write

可以按照以下方式为不同的用户添加不同的caps，但是不建议给普通用户开启任何caps

testcaps1用户
radosgw-admin caps add --uid=testcaps1 --caps="users=*" 

testcaps2用户
radosgw-admin caps add --uid=testcaps2 --caps="buckets=*"

testcaps3用户
radosgw-admin caps add --uid=testcaps3 --caps="metadata=*" 

testcaps4用户
radosgw-admin caps add --uid=testcaps4 --caps="usage=*"

testcaps5用户
radosgw-admin caps add --uid=testcaps5 --caps="zone=*"

对照http://docs.ceph.com/docs/jewel/radosgw/adminops/的介绍

cap为usage=read

用户拥有 usage=read 的可以查看调用admin rest api 的 usage 接口

于是只有testcaps4是可以

{"entries":[],"summary":[]}

其他用户则无权限获取usage的统计信息

cap为usage=write

拥有该cap的用户可以删除usage的统计信息

DELETE /{admin}/usage?format=json HTTP/1.1

#cap为users=read 该cap的用户可以获取用户信息 display_name user_id suspended max_buckets subusers keys swift_keys caps，获取配额信息

GET /{admin}/user?format=json HTTP/1.1

cap为users=write

该cap的用户可以创建或修改或删除其他用户或子用户,添加用户的cap，删除用户cap,创建key，删除key，修改key，修改配额

PUT /{admin}/user?format=json HTTP/1.1
Host: {fqdn}
PUT /{admin}/user?caps&format=json HTTP/1.1
Host {fqdn}

cap为buckets=read

该cap的用户可获取bucket信息,对象或Bucket的acl

GET /{admin}/bucket?format=json HTTP/1.1
Host {fqdn}
GET /{admin}/bucket?policy&format=json HTTP/1.1
Host {fqdn}

cap为buckets=write

该cap的用户可以check bucket index，删除bucket，unlink bucket，link bucket,删除对象(不论桶还是对象是不是属于该用户)

GET /{admin}/bucket?index&format=json HTTP/1.1
Host {fqdn}
DELETE /{admin}/bucket?format=json HTTP/1.1

PUT /{admin}/bucket?format=json HTTP/1.1
Host {fqdn}
DELETE /{admin}/bucket?object&format=json HTTP/1.1
Host {fqdn}

cap为metadata=read

该cap的用户可以读取user 和 bucket的metadata

cap为zone=write

有该cap权限的用户可以修改zone相关的信息

PUT  /admin/config HTTP/1.1
body体内容为json格式

注意： 可以通过ADMIN REST API 修改zone等信息，实现bucket与pool的绑定，而不用命令行来进行bucket与pool的绑定操作
