need to encrypt user and password string in a yaml file using a regex

[GuillaumeBettayeb]

Hi everyone,

I have the following data file:

[..]
data:
  admin-user: admin
  admin-password: SomeSecurePasswordHere

I need to encrypt the admin-user and admin-password values with sops.

my .sops config file is:

---
creation_rules:
  - path_regex: values.*.yaml$
    kms: 'arn:aws:kms:xx-xxxx-1:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX:role/kms_helm_secrets'
    encrypted_suffix: secrets

when I try encrypting in the command line with:
sops --encrypt --unencrypted-regex '(admin-[a-z]*)' myfile.yaml

it seems to be working, but when I try to encrypt the file itself, it fails with the following error message:

sops metadata not found

my question is, how can I encrypt the admin-user and admin-password strings with sops ?

thanks
