# 解码和编辑Secret
|
||
|
||
## 解码Secret
|
||
|
||
Secret 中的信息可以通过 `kubectl get secret` 命令获取。例如，执行命令 `kubectl get secret mysecret -o yaml
|
||
` 可获取前面章节中所创建的 Secret，输出信息如下：
|
||
|
||
```
|
||
apiVersion: v1
|
||
kind: Secret
|
||
metadata:
|
||
creationTimestamp: 2016-01-22T18:41:56Z
|
||
name: mysecret
|
||
namespace: default
|
||
resourceVersion: "164619"
|
||
uid: cfee02d6-c137-11e5-8d73-42010af00002
|
||
type: Opaque
|
||
data:
|
||
username: YWRtaW4=
|
||
password: MWYyZDFlMmU2N2Rm
|
||
```
|
||
|
||
执行命令 `echo 'MWYyZDFlMmU2N2Rm' | base64 --decode` 可解码密码字段，输出结果如下：
|
||
|
||
```
|
||
1f2d1e2e67df
|
||
```
|
||
|
||
执行命令 `echo 'YWRtaW4=' | base64 --decode` 可解码用户名字段，输出结果如下：
|
||
|
||
```
|
||
admin
|
||
```
|
||
|
||
## 编辑Secret
|
||
|
||
执行命令 `kubectl edit secrets mysecret` 可以编辑已经创建的 Secret，该命令将打开一个类似于 `vi` 的文本编辑器，您可以直接编辑已经进行 base64 编码的字段，如下所示：
|
||
|
||
``` yaml {7,8}
|
||
# Please edit the object below. Lines beginning with a '#' will be ignored,
|
||
# and an empty file will abort the edit. If an error occurs while saving this file will be
|
||
# reopened with the relevant failures.
|
||
#
|
||
apiVersion: v1
|
||
data:
|
||
username: YWRtaW4=
|
||
password: MWYyZDFlMmU2N2Rm
|
||
kind: Secret
|
||

|
