Mengonfigurasi sertifikat SSL untuk koneksi TCP dengan menggunakan Python

Konfigurasikan sertifikat SSL (Secure Sockets Layer) untuk koneksi TCP ke Cloud SQL untuk MySQL menggunakan paket sqlalchemy Python.

Contoh kode

    # Note: Saving credentials in environment variables is convenient, but not
    # secure - consider a more secure solution such as
    # Cloud Secret Manager (https://cloud.google.com/secret-manager) to help
    # keep secrets safe.

        "INSTANCE_HOST"

    # using the Cloud SQL Proxy, configuring SSL certificates will ensure the
    # connection is encrypted.
