S3 Resource

Versions objects in an S3 bucket, by pattern-matching filenames to identify version numbers.

Source Configuration

• access_key_id: Required. The AWS access key to use when accessing the bucket.

• secret_access_key: Required. The AWS secret key to use when accessing the bucket.

• bucket: Required. The name of the bucket.

• region_name: Optional. The region the bucket is in. Defaults to us-east-1.

• private: Optional. Indicates that the bucket is private, so that any URLs provided are signed.

• cloudfront_url: Optional. The URL (scheme and domain) of your CloudFront distribution that is fronting this bucket. This will be used in the url file that is given to the following task.

• endpoint: Optional. Custom endpoint for using S3 compatible provider.

• disable_md5_hash_check: Optional. Disables MD5 hash checking of files while uploading/downloading.

File Names

One of the following two options must be specified:

• regexp: Optional. The pattern to match filenames against. The first grouped match is used to extract the version, or if a group is explicitly named version, that group is used.

  The version extracted from this pattern is used to version the resource. Semantic versions, or just numbers, are supported.

• versioned_file: Optional If you enable versioning for your S3 bucket then you can keep the file name the same and upload new versions of your file without resorting to version numbers. This property is the path to the file in your S3 bucket.

Behavior

check: Extract versions from the bucket.

Objects will be found via the pattern configured by regexp. The versions will be used to order them (using semver). Each object's filename is the resulting version.

in: Fetch an object from the bucket.

Places the following files in the destination:

• (filename): The file fetched from the bucket.

• url: A file containing the URL of the object. If private is true, this URL will be signed.

• version: The version identified in the file name.

Parameters

None.

out: Upload an object to the bucket.

Given a path specified by from, upload it to the S3 bucket, optionally to a directory configured by to. The path must identify a single file.

Parameters

• from: Required. A regexp specifying the file to upload. If the regexp matches more than one file, the output fails.

• to: Optional. A destination directory in the bucket.
