Create and configure the custom Serverless deployment bucket.


By default, Serverless creates a bucket with a generated name like <service name>-serverlessdeploymentbuck-1x6jug5lzfnl7 to store your service's stack state. This can lead to many old deployment buckets laying around in your AWS account and your service having more than one bucket created (only one bucket is actually used).

Serverless' AWS provider can be configured to customize aspects of the deployment bucket, such as specifying server-side encryption and a custom deployment bucket name. However, server-side encryption is only applied to the objects that Serverless puts into the bucket and is not applied on the bucket itself. Furthermore, if the bucket name you specify doesn't exist, you will encounter an error like:

Serverless Error ---------------------------------------

  Could not locate deployment bucket. Error: The specified bucket does not exist

This plugin will create your custom deployment bucket if it doesn't exist, and optionally configure the deployment bucket to apply server-side encryption by default on objects, regardless of whether the bucket was created by this plugin and as long as you configure the provider with serverSideEncryption: AES256.

This plugin also provides the optional ability to enable versioning of bucket objects, however this is not enabled by default since Serverless tends to keep its own copies and versions of state.


npm install serverless-deployment-bucket --save-dev


Add the plugin to your serverless.yml:

  - serverless-deployment-bucket

Configure the AWS provider to use a custom deployment bucket:

    name: your-custom-deployment-bucket
    serverSideEncryption: AES256

Optionally add custom configuration properties:

    versioning: true
Property Required Type Default Description
versioning false boolean false Enable versioning on the deployment bucket


Configuration of your serverless.yml is all you need.

There are no custom commands, just run: sls deploy
