serverless-s3-deploy

Plugin for serverless to deploy files to a variety of S3 Buckets

Note: This project is currently not maintained.

Installation

 npm install --save-dev serverless-s3-deploy

Usage

Add to your serverless.yml:

  plugins:
    - serverless-s3-deploy

  custom:
    assets:
      targets:
       - bucket: my-bucket
         files:
          - source: ../assets/
            globs: '**/*.css'
          - source: ../app/
            globs:
              - '**/*.js'
              - '**/*.map'
       - bucket: my-other-bucket
         empty: true
         prefix: subdir
         files:
          - source: ../email-templates/
            globs: '**/*.html'

You can specify any number of targets that you want. Each target has a bucket and a prefix.

bucket is either the name of your S3 bucket or a reference to a CloudFormation resources created in the same serverless configuration file. See below for additional details.

You can specify source relative to the current directory.

Each source has its own list of globs, which can be either a single glob, or a list of globs.

Setting empty to true will delete all files inside the bucket before uploading the new content to S3 bucket. The prefix value is respected and files outside will not be deleted.

Now you can upload all of these assets to your bucket by running:

$ sls s3deploy

If you have defined multiple buckets, you can limit your deployment to a single bucket with the --bucket option:

$ sls s3deploy --bucket my-bucket

ACL

You can optionally specificy an ACL for the files uploaded on a per target basis:

  custom:
    assets:
      targets:
        - bucket: my-bucket
          acl: private
          files:

The default value is private. Options are defined here.

Content Type

The appropriate Content Type for each file will attempt to be determined using mime-types. If one can't be determined, a default fallback of 'application/octet-stream' will be used.

You can override this fallback per-source by setting defaultContentType.

  custom:
    assets:
      targets:
        - bucket: my-bucket
          files:
            - source: html/
              defaultContentType: text/html
              ...

Other Headers

Additional headers can be included per target by providing a headers object.

See http://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectPUT.html for more details.

  custom:
    assets:
      targets:
        - bucket: my-bucket
          files:
            - source: html/
              headers:
                CacheControl: max-age=31104000 # 1 year

Resolving References

A common use case is to create the S3 buckets in the resources section of your serverless configuration and then reference it in your S3 plugin settings:

  custom:
    assets:
      targets:
        - bucket:
            Ref: MyBucket
          files:
            - source: html/

  resources:
    # AWS CloudFormation Template
    Resources:
      MyBucket:
        Type: AWS::S3::Bucket
        Properties:
          AccessControl: PublicRead
          WebsiteConfiguration:
            IndexDocument: index.html
            ErrorDocument: index.html

You can disable the resolving with the following flag:

  custom:
    assets:
      resolveReferences: false

Auto-deploy

If you want s3deploy to run automatically after a deploy, set the auto flag:

  custom:
    assets:
      auto: true

IAM Configuration

You're going to need an IAM policy that supports this deployment. This might be a good starting point:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "s3:ListBucket"
            ],
            "Resource": [
                "arn:aws:s3:::${bucket}"
            ]
        },
        {
            "Effect": "Allow",
            "Action": [
                "s3:PutObject",
                "s3:PutObjectAcl",
                "s3:GetObject",
                "s3:DeleteObject"
            ],
            "Resource": [
                "arn:aws:s3:::${bucket}/*"
            ]
        }
    ]
}

Upload concurrency

If you want to tweak the upload concurrency, change uploadConcurrency config:

config:
  assets:
    # defaults to 3
    uploadConcurrency: 1

Verbosity

Verbosity cloud be enabled using either of these methods:

Configuration:

  custom:
    assets:
      verbose: true

Cli:

  sls s3deploy -v
