Akses variabel lingkungan melalui process objek Node.

npm install @types/node

new MyDevStack(app, 'dev', { 
  env: { 
    account: process.env.CDK_DEFAULT_ACCOUNT, 
    region: process.env.CDK_DEFAULT_REGION 
}});

Akses variabel lingkungan melalui process objek Node.

new MyDevStack(app, 'dev', { 
  env: { 
    account: process.env.CDK_DEFAULT_ACCOUNT, 
    region: process.env.CDK_DEFAULT_REGION 
}});

Gunakan environ kamus os modul untuk mengakses variabel lingkungan.

import os
MyDevStack(app, "dev", env=cdk.Environment(
    account=os.environ["CDK_DEFAULT_ACCOUNT"],
    region=os.environ["CDK_DEFAULT_REGION"]))

Gunakan System.getenv() untuk mendapatkan nilai variabel lingkungan.

public class MyApp {

    // Helper method to build an environment
    static Environment makeEnv(String account, String region) {
        account = (account == null) ? System.getenv("CDK_DEFAULT_ACCOUNT") : account;
        region = (region == null) ? System.getenv("CDK_DEFAULT_REGION") : region;

        return Environment.builder()
                .account(account)
                .region(region)
                .build();
    }

    public static void main(final String argv[]) {
        App app = new App();

        Environment envEU = makeEnv(null, null);
        Environment envUSA = makeEnv(null, null);
        
        new MyDevStack(app, "first-stack-us", StackProps.builder()
                .env(envUSA).build());
        new MyDevStack(app, "first-stack-eu", StackProps.builder()
                .env(envEU).build());
 
        app.synth();
    }
}

Gunakan System.Environment.GetEnvironmentVariable() untuk mendapatkan nilai variabel lingkungan.

Amazon.CDK.Environment makeEnv(string account=null, string region=null)
{
    return new Amazon.CDK.Environment
    {
        Account = account ?? System.Environment.GetEnvironmentVariable("CDK_DEFAULT_ACCOUNT"),
        Region = region ?? System.Environment.GetEnvironmentVariable("CDK_DEFAULT_REGION")

Simpan skrip sebagaicdk-deploy-to.sh, lalu jalankan chmod +x cdk-deploy-to.sh untuk membuatnya dapat dieksekusi.

Versi Windows skrip digunakan PowerShell untuk menyediakan fungsionalitas yang sama dengan versi macOS/Linux. Ini juga berisi instruksi untuk memungkinkannya dijalankan sebagai file batch sehingga dapat dengan mudah dipanggil dari baris perintah. Itu harus disimpan sebagaicdk-deploy-to.bat. File cdk-deploy-to.ps1 akan dibuat ketika file batch dipanggil.
