无法在Kubernetes中创建Secret:输入时存在非法的base64数据 [英] Can't create Secret in Kubernetes: illegal base64 data at input

问题描述

我想为我的kubernetes集群创建一个秘密.因此，我编写了以下dummy-secret.yaml文件:

I want to create a secret for my kubernetes cluster. So I composed following dummy-secret.yaml file:

apiVersion: v1
kind: Secret
metadata:
  name: dummy-secret
type: Opaque
data:
  API_KEY: bWVnYV9zZWNyZXRfa2V5
  API_SECRET: cmVhbGx5X3NlY3JldF92YWx1ZTE=

当我运行kubectl create -f dummy-secret.yaml时，我收到以下消息:

When I run kubectl create -f dummy-secret.yaml I receive back following message:

Error from server (BadRequest): error when creating "dummy-secret.yaml": Secret in version "v1" cannot be handled as a Secret: v1.Secret: Data: decode base64: illegal base64 data at input byte 8, error found in #10 byte of ...|Q89_Hj1Aq","API_SECR|..., bigger context ...|sion":"v1","data":{"API_KEY":"af76fsdK_cQ89_Hj1Aq","API_SECRET":"bsdfmkwegwegwe"},"kind":"Secret","m|...

不确定为什么会发生.

Not sure why it happens.

据我了解，我需要对yaml文件中data键下的所有值进行编码.所以我做了base64编码，但是kubernetes仍然无法像我期望的那样处理yaml秘密文件.

As I understood, I need to encode all values under the data key in the yaml file. So I did base64 encoding, but kubernetes still doesn't handle the yaml secret file as I expect.

更新:

我使用此命令在Mac上对data值进行编码:

I used this command to encode data values on my mac:

echo -n 'mega_secret_key' | openssl base64

推荐答案

我从编码数据中获得了解码后的值"mega_secret_key"和"really_secret_value1".似乎它们的编码方式不正确.因此，以正确的方式对数据进行编码:

I got the decoded values "mega_secret_key" and "really_secret_value1" from from your encoded data. Seems they are not encoded in right way. So, encode your data in right way:

$ echo "mega_secret_key" | base64
bWVnYV9zZWNyZXRfa2V5Cg==

$ echo "really_secret_value1" | base64
cmVhbGx5X3NlY3JldF92YWx1ZTEK

然后检查它们是否正确编码:

Then check whether they are encoded properly:

$ echo "bWVnYV9zZWNyZXRfa2V5Cg==" | base64 -d
mega_secret_key

$ echo "cmVhbGx5X3NlY3JldF92YWx1ZTEK" | base64 -d
really_secret_value1

这样就可以了.现在，在您的dummy-secret.yaml中使用它们:

So they are ok. Now use them in your dummy-secret.yaml:

apiVersion: v1
kind: Secret
metadata:
  name: dummy-secret
type: Opaque
data:
  API_KEY: bWVnYV9zZWNyZXRfa2V5Cg==
  API_SECRET: cmVhbGx5X3NlY3JldF92YWx1ZTEK

然后运行$ kubectl create -f dummy-secret.yaml.
