ckanext-s3filestore

Use Amazon S3 or Minio<https://minio.io/> as a filestore for resources.

Requirements

Requires CKAN 2.9+

When installing this extension on CKAN versions prior 2.9 please use ckan-2.8 branch.

Installation

To install ckanext-s3filestore:

1. Activate your CKAN virtual environment, for example:

   . /usr/lib/ckan/default/bin/activate
   

2. Install the ckanext-s3filestore Python package into your virtual environment:

   pip install ckanext-s3filestore
   

3. Add s3filestore to the ckan.plugins setting in your CKAN config file (by default the config file is located at /etc/ckan/default/ckan.ini).

4. Restart CKAN. For example if you've deployed CKAN with Apache on Ubuntu:

   sudo service apache2 reload
   

Config Settings

Required:

ckanext.s3filestore.aws_bucket_name = a-bucket-to-store-your-stuff
ckanext.s3filestore.region_name= region-name
ckanext.s3filestore.signature_version = s3v4

Conditional:

ckanext.s3filestore.aws_access_key_id = Your-Access-Key-ID
ckanext.s3filestore.aws_secret_access_key = Your-Secret-Access-Key

Or:

ckanext.s3filestore.aws_use_ami_role = true

Optional:

# An optional path to prepend to keys
ckanext.s3filestore.aws_storage_path = my-site-name

# An optional setting to fallback to filesystem for downloads
ckanext.s3filestore.filesystem_download_fallback = true
# The ckan storage path option must also be set correctly for the fallback to work
ckan.storage_path = path/to/storage/directory

# An optional setting to change the acl of the uploaded files. Default public-read.
ckanext.s3filestore.acl = private

# An optional setting to specify which addressing style to use. This controls whether the bucket name is in the hostname or is part of the URL. Default auto.
ckanext.s3filestore.addressing_style = path

# Set this parameter only if you want to use Minio as a filestore service instead of S3.
ckanext.s3filestore.host_name = http://minio-service.com

# To mask the S3 endpoint with your own domain/endpoint when serving URLs to end users.
# This endpoint should be capable of serving S3 objects as if it were an actual bucket.
# The real S3 endpoint will still be used for uploading files.
ckanext.s3filestore.download_proxy = https://example.com/my-bucket

# Defines how long a signed URL is valid (default 1 hour).
ckanext.s3filestore.signed_url_expiry = 3600

# Don't check for access on each startup
ckanext.s3filestore.check_access_on_startup = false
