Quick snippet to convert values into base64 encoding for usage with Kubernetes secrets.yml files

converter.py

import yaml
import base64

# Assumes sample.yml will have a data: entry
if __name__ == '__main__':
    with open('sample.yml', 'r') as fh:
        stream = fh.read()
    data = yaml.safe_load(stream)
    for key, value in data['data'].items():
        encoded = base64.b64encode(str(value).encode('utf-8')).decode('utf-8')
        print(f"{key}: {encoded}")

Sample yml:

apiVersion: v1
data:
  SECRET1: supersecret123
  SECRET2: topsecrethere
kind: Secret
metadata:
  name: deploymentSecrets
  namespace: myspace
type: Opaque
