Creating and accessing secrets

This topic describes how to create a secret, add a secret version, and access a secret version. For information about managing secrets, see Managing secrets.

Note: To access the Secret Manager API from within a Compute Engine instance or a Google Kubernetes Engine node (which is also a Compute Engine instance), the instance or node must have the cloud-platform OAuth scope. For more information about access scopes in Compute Engine, see Service account permissions in the Compute Engine documentation.

Before you begin

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

Creating a secret

A secret contains one or more secret versions, along with metadata such as labels and replication information. The actual contents of a secret are stored in a secret version.

If you aren't sure which replication policy is right for your secret, see Choosing A Replication Policy.

Creating a secret requires the Secret Manager Admin role (roles/secretmanager.admin) on the project, folder, or organization.

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 Create Secret.

3. On the Create secret page, under Name, enter my-secret.

4. (Optional) In the Secret value field, enter abcd1234 to also add a secret version when creating the initial secret.

5. Leave the Regions section unchanged.

6. Click the Create secret button.

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 create secret-id \
    --replication-policy="automatic"

API

Adding a secret version

A secret version contains the actual contents of a secret. A secret version can be enabled, disabled, or destroyed. To change the contents of a secret, you create a new version.

Adding a secret version requires the Secret Manager Admin role (roles/secretmanager.admin) on the secret, project, folder, or organization. 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 View more and select Add new version.

3. In the Add new version dialog, in the Secret value field, enter abcd1234.

4. Click the Add new version button.

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.

Add a secret version from the contents of a file on disk:

$ gcloud secrets versions add secret-id --data-file="/path/to/file.txt"

You can also add a secret version directly on the command line, but this is discouraged because the plaintext will appear in your shell history:

$ echo -n "this is my super secret data" | \
    gcloud secrets versions add secret-id --data-file=-

Optionally: Add a version from a file's contents when first creating a secret:

$ gcloud secrets create secret-id --data-file="/path/to/file.txt"

API

These examples use curl to demonstrate using the API.

Base64-encode the secret data and save it as a shell variable.

$ SECRET_DATA=$(echo "seCr3t" | base64)

Invoke the API using curl.

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

    --header "x-goog-user-project: project-id" \
    --data "{\"payload\": {\"data\": \"${SECRET_DATA}\"}}"

Accessing a secret version

Accessing a secret version returns the secret contents, as well as additional metadata about the secret version. When you access a secret version, you specify its version-id. You can also access the latest version of a secret by specifying "latest" as the version.

Accessing a secret version requires the Secret Manager Secret Accessor role (roles/secretmanager.secretAccessor) on the secret, project, folder, or organization. IAM roles can't be granted on a secret version.

A note on resource consistency

In Secret Manager, adding a secret version and then immediately accessing that secret version is a strongly consistent operation. Other operations within Secret Manager are eventually consistent. Eventually consistent operations typically converge within minutes, but may take a few hours.

Propagating IAM permissions is eventually consistent. This means granting or revoking access to secrets may not take effect immediately. For more information, see the IAM documentation.

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. On the Secret details page, in the Versions table, locate a secret version to access.

4. In the Actions column, click View more.

5. Click View secret value from the menu.

6. You will see dialog that shows the secret version value. Click Done to finish.

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.

Cloud SDK versions prior to 306.0.0 logged the secret material in your home directory. Please upgrade or set core/disable_file_logging to true.

Access a secret version:

$ gcloud secrets versions access version-id --secret="secret-id"

Accessing a binary secret version:

Cloud SDK formats the output as UTF-8 which can corrupt binary secrets. To get the raw bytes, have Cloud SDK print the response as base64-encoded and decode.

$ gcloud secrets versions access version-id --secret="secret-id" --format='get(payload.data)' | tr '_-' '/+' | base64 -d

API

These examples use curl to demonstrate using the API.

$ curl "https://secretmanager.googleapis.com/v1/projects/project-id/secrets/secret-id/versions/version-id:access" \
    --request "GET" \
    --header "authorization: Bearer $(gcloud auth print-access-token)" \
    --header "content-type: application/json" \
    --header "x-goog-user-project: project-id"

The response payload.data is the base64-encoded contents of the secret version. Here is an example of extracting the secret using the jq tool:

$ curl "https://secretmanager.googleapis.com/v1/projects/project-id/secrets/secret-id/versions/version-id:access" \
    --request "GET" \
    --header "authorization: Bearer $(gcloud auth print-access-token)" \
    --header "content-type: application/json" \
    --header "x-goog-user-project: project-id" \
    | jq -r ".payload.data" | base64 --decode
