Managing secrets

In Secret Manager, a secret is a wrapper around a collection of secret versions. The secret stores metadata such as labels and replication, but it does not contain the actual secret. This topic describes how to manage secrets. You can also manage a secret's versions.

Before you begin

Configure Secret Manager and your local environment, once per project.

Listing secrets

These examples show how to list all secrets you have permission to view in the project.

Listing secrets requires the Secret Viewer role (roles/secretmanager.viewer) on the secret, project, folder, or organization. IAM roles can't be granted on a secret version.

Web UI

  1. Go to the Secret Manager page in the Cloud Console.

    Go to the Secret Manager page

  2. This page displays the list of Secrets in the project.

Command-line

To use Secret Manager on the command line, first Install or upgrade to version 306.0.0 or higher of the Cloud SDK.

$ gcloud secrets list

C#

To run this code, first set up a C# development environment and install the Secret Manager C# SDK.


using Google.Api.Gax.ResourceNames;
using Google.Cloud.SecretManager.V1;

public class ListSecretsSample
{
    public void ListSecrets(string projectId = "my-project")
    {
        // Create the client.
        SecretManagerServiceClient client = SecretManagerServiceClient.Create();

        // Build the resource name.
        ProjectName projectName = new ProjectName(projectId);

        // Call the API.
        foreach (Secret secret in client.ListSecrets(projectName))
        {
            // ...
        }
    }
}

Go

To run this code, first set up a Go development environment and install the Secret Manager Go SDK.

)

// listSecrets lists all secrets in the given project.
func listSecrets(w io.Writer, parent string) error {
	// parent := "projects/my-project"

	// Create the client.
	ctx := context.Background()
	client, err := secretmanager.NewClient(ctx)
	if err != nil {
		return fmt.Errorf("failed to create secretmanager client: %v", err)
	}

	// Build the request.
	req := &secretmanagerpb.ListSecretsRequest{
		Parent: parent,
	}

	// Call the API.
	it := client.ListSecrets(ctx, req)
	for {
		resp, err := it.Next()
		if err == iterator.Done {
			break
		}

		if err != nil {

Managing access to secrets

These examples show how to manage access to a secret version, including the secret material itself. To learn more about access controls and permissions, see the Secret Manager IAM documentation.

Managing access to a secret requires the Secret Admin role (roles/secretmanager.admin) on the secret, project, folder, or organization. IAM roles can't be granted on a secret version.

To grant access:

Web UI

  1. Go to the Secret Manager page in the Cloud Console.

    Go to the Secret Manager page

  2. On the Secret Manager page, click on the name of a Secret.

  3. If it is not already open, click Show Info Panel to open the panel.

  4. In the info panel, click Add Member.

  5. In the New members text area, enter the email address(es) of the members to add.

  6. In the Select a role dropdown, choose Secret Manager and then Secret Manager Secret Accessor.

Command-line

To use Secret Manager on the command line, first Install or upgrade to version 306.0.0 or higher of the Cloud SDK.

$ gcloud secrets add-iam-policy-binding secret-id \
    --member="member" \
    --role="roles/secretmanager.secretAccessor"

Where member is an IAM member, such as a user, group, or service account.

C#

To run this code, first set up a C# development environment and install the Secret Manager C# SDK.

        SecretManagerServiceClient client = SecretManagerServiceClient.Create();

        // Build the resource name.
        SecretName secretName = new SecretName(projectId, secretId);

        // Get current policy.
        Policy policy = client.GetIamPolicy(new GetIamPolicyRequest
        {
            ResourceAsResourceName = secretName,
        });

        // Add the user to the list of bindings.
        policy.AddRoleMember("roles/secretmanager.secretAccessor", member);

API

These examples use curl to demonstrate using the API.

Note: Unlike the other examples, this replaces the entire IAM policy.

$ curl "https://secretmanager.googleapis.com/v1/projects/project-id/secrets/secret-id:setIamPolicy" \
    --request "POST" \
    --header "authorization: Bearer $(gcloud auth print-access-token)" \

    --header "x-goog-user-project: project-id" \
    --data "{\"policy\": {\"bindings\": []}}"

Updating a secret

These examples show how to update a secret's metadata.

Updating a secret's metadata requires the Secret Admin role (roles/secretmanager.admin) on the secret or the project. IAM roles can't be granted on a secret version.

Web UI

  1. Go to the Secret Manager page in the Cloud Console.

    Go to the Secret Manager page

  2. On the Secret Manager page, click on the name of a Secret to update.

  3. If the Info Panel is closed, click Show Info Panel to display it.

  4. In the Info Panel, select the Labels tab.

  5. Click Add label and enter the key secretmanager with the value rocks.

  6. Click Save.
