Tool env2kube.sh - tool for converting .env files to Kubernetes deployment env definitions

#!/usr/bin/env python3
import sys

filename = sys.argv[1]

with open(filename) as file:
    lines = file.readlines()
    lines = [line.rstrip() for line in lines]
    for line in lines:
        if len(line) > 0:
            parts = line.split('=')
            if len(parts) > 1:
                if not parts[1].startswith('='):
                    parts[1] = '"' + parts[1] + '"'
                    print('- name: ' + parts[0])
                    print('  value: ' + parts[1])
