ltdconveyor.s3.upload_dir(bucket_name, path_prefix, source_dir, upload_dir_redirect_objects=True, surrogate_key=None, surrogate_control=None, cache_control=None, acl=None, aws_access_key_id=None, aws_secret_access_key=None, aws_profile=None)#

Upload a directory of files to S3.

This function places the contents of the Sphinx HTML build directory into the /path_prefix/ directory of an existing S3 bucket. Existing files on S3 are overwritten; files that no longer exist in the source_dir are deleted from S3.

Parameters:

  • bucket_name (str) – Name of the S3 bucket where documentation is uploaded.

  • path_prefix (str) – The root directory in the bucket where documentation is stored.

  • source_dir (str) – Path of the Sphinx HTML build directory on the local file system. The contents of this directory are uploaded into the /path_prefix/ directory of the S3 bucket.

  • upload_dir_redirect_objects (bool, optional) – A feature flag to enable uploading objects to S3 for every directory. These objects contain x-amz-meta-dir-redirect=true HTTP headers that tell Fastly to issue a 301 redirect from the directory object to the index.html` in that directory.

  • surrogate_key (str, optional) – The surrogate key to insert in the header of all objects in the x-amz-meta-surrogate-key field. This key is used to purge builds from the Fastly CDN when Editions change. If None then no header will be set.

  • cache_control (str, optional) – This sets the Cache-Control header on the uploaded files. The Cache-Control header specifically dictates how content is cached by the browser (if surrogate_control is also set).

  • surrogate_control (str, optional) – This sets the x-amz-meta-surrogate-control header on the uploaded files. The Surrogate-Control or x-amz-meta-surrogate-control header is used in priority by Fastly to givern it’s caching. This caching policy is not passed to the browser.

  • acl (str, optional) – The pre-canned AWS access control list to apply to this upload. Can be 'public-read', which allow files to be downloaded over HTTP by the public. See https://docs.aws.amazon.com/AmazonS3/latest/dev/acl-overview.html#canned-acl for an overview of S3’s pre-canned ACL lists. Note that ACL settings are not validated locally. Default is None, meaning that no ACL is applied to an individual object. In this case, use ACLs applied to the bucket itself.

  • aws_access_key_id (str, optional) – The access key for your AWS account. Also set aws_secret_access_key.

  • aws_secret_access_key (str, optional) – The secret key for your AWS account.

  • aws_profile (str, optional) – Name of AWS profile in ~/.aws/credentials. Use this instead of aws_access_key_id and aws_secret_access_key for file-based credentials.

Return type:

None

Notes

cache_control and surrogate_control can be used together. surrogate_control takes priority in setting Fastly’s POP caching, while cache_control then sets the browser’s caching. For example:

  • cache_control='no-cache'

  • surrogate_control='max-age=31536000'

together will ensure that the browser always does an ETAG server query, but that Fastly will cache the content for one year (or until purged). This configuration is good for files that are frequently changed in place.

For immutable uploads simply using cache_control is more efficient since it allows the browser to also locally cache content.
