ConfigMap中的内容是存储到etcd中的，然后查询etcd：
|
||||
|
||||
```bash
|
||||
ETCDCTL_API=3 etcdctl get /registry/configmaps/default/nginx-config
|
||||
/registry/configmaps/default/nginx-config
|
||||
ETCDCTL_API=3 etcdctl get /registry/configmaps/default/nginx-config -w json|python -m json.tool
|
||||
```
|
||||
|
||||
注意使用 v3 版本的 etcdctl API，下面是输出结果：

|

|

输出中在 `nginx.conf` 配置文件的基础中增加了文件头内容，是kubernetes增加的。
|
||||
其中的value就是 `nginx.conf` 配置文件的内容。
|
||||
|
||||
可以使用base64解码查看具体值，关于etcdctl的使用请参考[使用etcdctl访问kuberentes数据](../guide/using-etcdctl-to-access-kubernetes-data.md)。
