below is the secret file that i used

secret-test.yaml
apiVersion: xx
kind: Secret
metadata:
  name: xxxxx
  namespace: xxxxxxxx
type: Opaque
stringData:
  key_name: >
    PuTTY-User-Key-File-2: ssh-rsa\r\

Things i tried:

included |- , >-, only |,only >
tried enclosing in double quotes with backslash as escape character

something like below

         "PuTTY-User-Key-File-2: ssh-rsa\
         Encryption: none\
         Comment: rsa-key-20210504..."
still got the same error as above

CodePudding user response：

i tried with type as kubernetes.io/ssh-auth instead of Opaque and it worked !! thanks for the suggestions provided

CodePudding user response：

Did you tried the command :

kubectl create secret generic ssh-keys --from-file=id_rsa=/path/to/.ssh/id_rsa
