Container Analysis Client Libraries

This page shows how to get started with the Cloud Client Libraries for the Container Analysis API. Read more about the client libraries for Cloud APIs, including the older Google APIs Client Libraries, in Client Libraries Explained.

Installing the client library

Go

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

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

Java

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

If you are using Maven with a BOM, add the following to your pom.xml file:

<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-containeranalysis</artifactId>
  </dependency>

If you are using Maven without a BOM, add this to your dependencies:

<dependency>
  <groupId>com.google.cloud</groupId>
  <artifactId>google-cloud-containeranalysis</artifactId>
  <version>1.2.36</version>
</dependency>

If you are using Gradle, add the following to your dependencies:

implementation platform('com.google.cloud:libraries-bom:20.1.0')

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

If you are using sbt, add the following to your dependencies:

libraryDependencies += "com.google.cloud" % "google-cloud-containeranalysis" % "1.2.36"

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

• Cloud Code for IntelliJ
• Cloud Tools for Eclipse

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

Node.js

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

npm install @google-cloud/containeranalysis

Python

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

It is recommended to install this library in a virtualenv using pip. Virtualenv allows you to install the Python libraries in an isolated environment, preventing conflicts with the system dependencies.

• Mac and Linux

  pip install virtualenv
  virtualenv <your-env>
  source <your-env>/bin/activate
  <your-env>/bin/pip install google-cloud-containeranalysis</your-env></your-env></your-env>
  

• Windows

  pip install virtualenv
  virtualenv <your-env>
  <your-env>\Scripts\activate
  <your-env>\Scripts\pip.exe install google-cloud-containeranalysis</your-env></your-env></your-env>
  

Ruby

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

gem install google-cloud-container_analysis

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

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.

   Note: The Role field affects which resources your service account can access in your project. You can revoke these roles or grant additional roles later. In production environments, do not grant the Owner, Editor, or Viewer roles. For more information, see Granting, changing, and revoking access to resources.
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"

   Note: The --role flag affects which resources your service account can access in your project. You can revoke these roles or grant additional roles later. In production environments, do not grant the Owner, Editor, or Viewer roles. For more information, see Granting, changing, and revoking access to resources.

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. Replace [PATH] with the file path of the JSON file that contains your service account key. 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="[PATH]"

For example:

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

Windows

With PowerShell:

$env:GOOGLE_APPLICATION_CREDENTIALS="[PATH]"

For example:

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

With command prompt:

set GOOGLE_APPLICATION_CREDENTIALS=[PATH]

Using the client library

The following example shows how to use the client library.

	containeranalysis "cloud.google.com/go/containeranalysis/apiv1"
	grafeaspb "google.golang.org/genproto/googleapis/grafeas/v1"
)

// getOccurrence retrieves and prints a specified Occurrence from the server.
func getOccurrence(occurrenceID, projectID string) (*grafeaspb.Occurrence, error) {
	// occurrenceID := path.Base(occurrence.Name)
	ctx := context.Background()
	client, err := containeranalysis.NewClient(ctx)
	if err != nil {
		return nil, fmt.Errorf("NewClient: %v", err)
	}
	defer client.Close()

	req := &grafeaspb.GetOccurrenceRequest{
		Name: fmt.Sprintf("projects/%s/occurrences/%s", projectID, occurrenceID),
	}
	occ, err := client.GetGrafeasClient().GetOccurrence(ctx, req)
