    properties:
      headers:
        - key: Cache-Control
          value: ${CACHE_CONTROL:no-cache}
        - key: Content-Type
          value: application/json

    package main

    import (
		"github.com/siberia-projects/siberia-env/pkg/env"
		"io"
		"os"
    )

    func main() {
		file, _ := os.Open("path_to_the_yaml_file_above.yaml")
		defer file.Close()

		fileContent, _ := io.ReadAll(file)

		expandedFileContent, _ := env.ExpandEnvIn(fileContent)
		expandedFileContentString := string(expandedFileContent)
		
		println(expandedFileContentString)
    }
