Setting up client libraries

This page shows how to install client libraries for the Memorystore for Redis API so you can connect to the API with the language of your choice.

Installing the client library

C#

Install the Google.Cloud.Redis.V1 package in Visual Studio

Go

go get -u cloud.google.com/go/redis/apiv1

Java

If you are using Maven, add this to your pom.xml file:

<dependency>
    <groupId>com.google.cloud</groupId>
    <artifactId>google-cloud-redis</artifactId>
    <version>0.62.0-alpha</version>
</dependency>

If you are using Gradle, add this to your dependencies:

compile 'com.google.cloud:google-cloud-redis:0.62.0-alpha'

If you are using SBT, add this to your dependencies:

libraryDependencies += "com.google.cloud" % "google-cloud-redis" % "0.62.0-alpha"

If you're using IntelliJ or Eclipse, you can add client libraries to your project using these IDE plugins:

The plugins provide additional functionality, such as key management for service accounts. Refer to each plugin's documentation for details.

Node.js

npm install --save @google-cloud/redis

PHP

composer require google/cloud-redis

Python

For more on setting up your Python development environment, refer to Python Development Environment Setup Guide.
pip install --upgrade google-cloud-redis

Ruby

gem install google-cloud-redis

Setting up authentication

To run the client library, you must first set up authentication by creating a service account and setting an environment variable.

Cloud Console

Create a service account:

  1. In the Cloud Console, go to the Create service account page.

    Go to Create service account
  2. Select a project.
  3. In the Service account name field, enter a name. The Cloud Console fills in the Service account ID field based on this name.

    In the Service account description field, enter a description. For example, Service account for quickstart.

  4. Click Create.
  5. Click the Select a role field.

    Under Quick access, click Basic, then click Owner.

  6. Click Continue.
  7. Click Done to finish creating the service account.

    Do not close your browser window. You will use it in the next step.

Create a service account key:

  1. In the Cloud Console, click the email address for the service account that you created.
  2. Click Keys.
  3. Click Add key, then click Create new key.
  4. Click Create. A JSON key file is downloaded to your computer.
  5. Click Close.

Command line

You can run the following commands using the Cloud SDK on your local machine, or in Cloud Shell.

  1. Create the service account. Replace NAME with a name for the service account.

    gcloud iam service-accounts create NAME
  2. Grant permissions to the service account. Replace PROJECT_ID with your project ID.

    gcloud projects add-iam-policy-binding PROJECT_ID --member="serviceAccount:NAME@PROJECT_ID.iam.gserviceaccount.com" --role="roles/owner"
  3. Generate the key file. Replace FILE_NAME with a name for the key file.

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

Provide authentication credentials to your application code by setting the environment variable GOOGLE_APPLICATION_CREDENTIALS. This variable only applies to your current shell session, so if you open a new session, set the variable again.

Linux or macOS

export GOOGLE_APPLICATION_CREDENTIALS="KEY_PATH"

Replace KEY_PATH with the path of the JSON file that contains your service account key.

For example:

export GOOGLE_APPLICATION_CREDENTIALS="/home/user/Downloads/service-account-file.json"

Windows

For PowerShell:

$env:GOOGLE_APPLICATION_CREDENTIALS="KEY_PATH"

Replace KEY_PATH with the path of the JSON file that contains your service account key.

For example:

$env:GOOGLE_APPLICATION_CREDENTIALS="C:\Users\username\Downloads\service-account-file.json"

For command prompt:

set GOOGLE_APPLICATION_CREDENTIALS=KEY_PATH

Replace KEY_PATH with the path of the JSON file that contains your service account key.
