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.

Se você estiver usando o Maven, adicione o código abaixo ao arquivo pom.xml. Para mais informações sobre BOMs, consulte BOM das bibliotecas do Google Cloud Platform.

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>com.google.cloud</groupId>
      <artifactId>libraries-bom</artifactId>
      <version>20.1.0</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
  </dependencies>
</dependencyManagement>

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

Se você estiver usando o Gradle, adicione isto às dependências:

implementation platform('com.google.cloud:libraries-bom:19.2.1')

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

Se você estiver usando o sbt, adicione o seguinte às suas dependências:

libraryDependencies += "com.google.cloud" % "google-cloud-secretmanager" % "1.4.2"

Caso você esteja usando o IntelliJ ou o Eclipse, poderá adicionar bibliotecas de cliente ao seu projeto usando estes plug-ins de ambiente de desenvolvimento integrado:

Os plug-ins também oferecem outras funcionalidades, como gerenciamento de chaves de contas de serviço. Consulte a documentação de cada plug-in para mais detalhes.

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.

Console do Cloud

Crie uma conta de serviço:

  1. No Console do Cloud, acesse a página Criar conta de serviço.

    Acesse Criar conta de serviço
  2. Selecione um projeto.
  3. No campo Nome da conta de serviço, insira um nome. O Console do Cloud preenche o campo ID da conta de serviço com base nesse nome.

    No campo Descrição da conta de serviço, insira uma descrição. Por exemplo, Service account for quickstart.

  4. Clique em Criar.
  5. Clique no campo Selecionar um papel.

    Em Acesso rápido, clique em Básico e em Proprietário.

  6. Clique em Continuar.
  7. Clique em Concluído para terminar a criação da conta de serviço.

    Não feche a janela do navegador. Você vai usá-lo na próxima etapa.

Crie uma chave de conta de serviço:

  1. No Console do Cloud, clique no endereço de e-mail da conta de serviço que você criou.
  2. Clique em Chaves.
  3. Clique em Adicionar chave e em Criar nova chave.
  4. Clique em Criar. O download de um arquivo de chave JSON é feito no seu computador.
  5. Clique em Fechar.

Linha de comando

É possível executar os seguintes comandos usando o SDK do Cloud na máquina local ou no Cloud Shell.

  1. Crie a conta de serviço. Substitua NAME por um nome para a conta de serviço.

    gcloud iam service-accounts create NAME
  2. Conceda permissões à conta de serviço. Substitua PROJECT_ID pelo ID do seu projeto.

    gcloud projects add-iam-policy-binding PROJECT_ID --member="serviceAccount:NAME@PROJECT_ID.iam.gserviceaccount.com" --role="roles/owner"
  3. Gere o arquivo de chave. Substitua FILE_NAME pelo nome do arquivo de chave.

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

Forneça credenciais de autenticação ao código do aplicativo definindo a variável de ambiente GOOGLE_APPLICATION_CREDENTIALS. Substitua [PATH] pelo caminho do arquivo JSON que contém sua chave da conta de serviço. Essa variável só se aplica à sessão de shell atual. Assim, se você abrir uma nova sessão, precisará definir a variável novamente.

Linux ou macOS

export GOOGLE_APPLICATION_CREDENTIALS="[PATH]"

Exemplo:

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

Windows

Com o PowerShell:

$env:GOOGLE_APPLICATION_CREDENTIALS="[PATH]"

Exemplo:

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

Com prompt de comando:

set GOOGLE_APPLICATION_CREDENTIALS=[PATH]
