Use entity tags for optimistic concurrency control

Secret Manager supports using entity tags (ETags) for optimistic concurrency control.

In some cases, two processes updating the same resource in parallel may interfere with one another, where the latter process overwrites the effort of the former one.

ETags provide a means for optimistic concurrency control by allowing processes to see if a resource has been modified before taking action on that resource.

Use ETags with Secret Manager

The following resource modification requests support ETags:

In a secrets.patch request, the request ETag is embedded in the Secret data. All other requests accept an optional etag parameter.

If an ETag is provided and matches the current resource ETag, the request succeeds; otherwise, it fails with a FAILED_PRECONDITION error and an HTTP status code 400. If an ETag isn't provided, the request proceeds without checking the currently stored ETag value.

Resource ETags are generated at resource creation (projects.secrets.create, projects.secrets.addVersion) and updated for each of the above-listed modification requests. A modification request only updates the ETag of the resource to which it applies. That is, updating a secret version doesn't affect the secret ETag, and similarly, updating the ETag doesn't affect the secret version.

Even when an update doesn't change a resource's state, it still updates the resource ETag.

Consider the following example:

  • User 1 tries to enable a secret version unaware that it's already enabled. The system processes this, changing nothing but the version's ETag.

  • User 2, using the old ETag, tries to disable the version.

  • This fails because the system recognizes the newer ETag, which indicates a more recent intent to keep the version enabled.

Even seemingly minor updates matter due to ETag changes. This ensures data consistency, especially with multiple users or systems interacting with the same resource.

The resource etag is returned in the response whenever a resource (Secret or SecretVersion) is included.

Delete a secret with ETags

This section describes using ETags when deleting a secret. If the secret has been modified by another process, the delete operation fails.

gcloud

Before using any of the command data below, make the following replacements:

  • SECRET_ID: the ID of the secret or fully qualified identifier for the secret.
  • LOCATION: the Google Cloud location of the secret.
  • ETAG: the entity tag of the secret. The ETag must include the surrounding quotes. For example, if the ETag value was "abc", the shell-escaped value would be "\"abc\"".

Execute the following command:

Linux, macOS, or Cloud Shell

gcloud secrets delete SECRET_ID --location=LOCATION \
    --etag "ETAG"

Windows (PowerShell)

gcloud secrets delete SECRET_ID --location=LOCATION `
    --etag "ETAG"

Windows (cmd.exe)

gcloud secrets delete SECRET_ID --location=LOCATION ^
    --etag "ETAG"

REST

Before using any of the request data, make the following replacements:

  • LOCATION: the Google Cloud location of the secret.
  • PROJECT_ID: the Google Cloud project ID.
  • SECRET_ID: the ID of the secret or fully qualified identifier for the secret.
  • ETAG: the entity tag of the secret. The ETag is specified as part of the URL's querystring and must be URL-encoded. For example, if the ETag value is "abc", the URL-encoded value would be %22abc%22 because the quote character is encoded as %22.

HTTP method and URL: 

DELETE https://secretmanager.LOCATION.rep.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/secrets/SECRET_ID?etag=ETAG

Request JSON body: 

{}

To send your request, choose one of these options:

curl

Save the request body in a file named request.json, and execute the following command: 

curl -X DELETE \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "Content-Type: application/json; charset=utf-8" \
     -d @request.json \
     "https://secretmanager.LOCATION.rep.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/secrets/SECRET_ID?etag=ETAG"

PowerShell

Save the request body in a file named request.json, and execute the following command: 

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
    -Method DELETE `
    -Headers $headers `
    -ContentType: "application/json; charset=utf-8" `
    -InFile request.json `
    -Uri "https://secretmanager.LOCATION.rep.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/secrets/SECRET_ID?etag=ETAG" | Select-Object -Expand Content

You should receive a JSON response similar to the following:
