Secret Manager Client Libraries

This page shows how to get started with the Cloud Client Libraries for the Secret Manager API. Read more about the client libraries for Cloud APIs in Client Libraries Explained.

Installing the client library

C#

For more information, see Setting Up a C# Development Environment.

Using PowerShell:

$ Install-Package Google.Cloud.SecretManager.V1 -Version 1.0.0

Using the dotnet CLI:

$ dotnet add package Google.Cloud.SecretManager.V1 --version 1.0.0

Go

For more information, see Setting Up a Go Development Environment.

$ go get -u cloud.google.com/go/secretmanager/apiv1
$ go get -u google.golang.org/genproto/googleapis/cloud/secretmanager/v1

Java

For more information, see Setting Up a Java Development Environment.

Wenn Sie Maven verwenden, fügen Sie Ihrer Datei pom.xml den folgenden Code hinzu. Weitere Informationen zu BOMs finden Sie unter The Google Cloud Platform Libraries BOM.

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>com.google.cloud</groupId>
      <artifactId>libraries-bom</artifactId>
      <version>16.1.0</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
  </dependencies>
</dependencyManagement>

<dependencies>
  <dependency>
    <groupId>com.google.cloud</groupId>
    <artifactId>google-cloud-secretmanager</artifactId>
  </dependency>
</dependencies>

Wenn Sie Gradle verwenden, fügen Sie den Abhängigkeiten Folgendes hinzu:

compile 'com.google.cloud:google-cloud-secretmanager:1.2.5'

Wenn Sie sbt nutzen, fügen Sie den Abhängigkeiten Folgendes hinzu:

libraryDependencies += "com.google.cloud" % "google-cloud-secretmanager" % "1.2.5"

Bei Verwendung von IntelliJ oder Eclipse können Sie Ihrem Projekt mithilfe der folgenden IDE-Plug-ins Clientbibliotheken hinzufügen:

Diese Plug-ins bieten zusätzliche Funktionen wie die Schlüsselverwaltung für Dienstkonten. Einzelheiten finden Sie in der Dokumentation der einzelnen Plug-ins.

Node.js

For more information, see Setting Up a Node.js Development Environment.

$ npm install --save @google-cloud/secret-manager

PHP

For more information, see Using PHP on Google Cloud.

$ composer require google/cloud-secret-manager

Python

For more information, see Setting Up a Python Development Environment.

$ pip install google-cloud-secret-manager

Ruby

For more information, see Setting Up a Ruby Development Environment.

$ gem install google-cloud-secret_manager

Setting up authentication

To run the client library, you must first set up authentication by creating a service account and setting an environment variable. Complete the following steps to set up authentication. For other ways to authenticate, see the GCP authentication documentation.

Cloud Console

  1. Wechseln Sie in der Cloud Console zur Seite Dienstkontoschlüssel erstellen.

    Zur Seite „Dienstkontoschlüssel erstellen“
  2. Wählen Sie aus der Liste Dienstkonto die Option Neues Dienstkonto aus.
  3. Geben Sie im Feld Dienstkontoname einen Namen ein.
  4. Wählen Sie in der Liste Rolle die Option Projekt > Inhaber

  5. Klicken Sie auf Erstellen. Eine JSON-Datei mit Ihrem Schlüssel wird auf Ihren Computer heruntergeladen.

Befehlszeile

Sie können die folgenden Befehle mithilfe des Cloud SDK auf Ihrem lokalen Computer oder in Cloud Shell ausführen.

  1. Erstellen Sie das Dienstkonto. Ersetzen Sie NAME mit einem Namen für das Dienstkonto.

    gcloud iam service-accounts create NAME
  2. Gewähren Sie dem Dienstkonto Berechtigungen. Geben Sie für PROJECT_ID Ihre Projekt-ID an.

    gcloud projects add-iam-policy-binding PROJECT_ID --member="serviceAccount:NAME@PROJECT_ID.iam.gserviceaccount.com" --role="roles/owner"
  3. Erstellen Sie die Schlüsseldatei. Geben Sie für FILE_NAME einen Namen für die Schlüsseldatei an.

    gcloud iam service-accounts keys create FILE_NAME.json --iam-account=NAME@PROJECT_ID.iam.gserviceaccount.com

Die Anmeldedaten zur Authentifizierung für Ihren Anwendungscode geben Sie durch Festlegung der Umgebungsvariable GOOGLE_APPLICATION_CREDENTIALS an. Geben Sie für [PATH] den Dateipfad der JSON-Datei an, die Ihren Dienstkontoschlüssel enthält. Diese Variable gilt nur für Ihre aktuelle Shell-Sitzung. Wenn Sie eine neue Sitzung öffnen, müssen Sie die Variable neu festlegen.

Linux oder macOS

export GOOGLE_APPLICATION_CREDENTIALS="[PATH]"

Beispiel:

export GOOGLE_APPLICATION_CREDENTIALS="/home/user/Downloads/my-key.json"

Windows

Mit PowerShell:

$env:GOOGLE_APPLICATION_CREDENTIALS="[PATH]"

Beispiel:

$env:GOOGLE_APPLICATION_CREDENTIALS="C:\Users\username\Downloads\my-key.json"

Mit Eingabeaufforderung:

set GOOGLE_APPLICATION_CREDENTIALS=[PATH]
