Using an external blobstore

1. Create the necessary buckets using aws-cli:

   REGION=<your-region>
   aws s3api create-bucket --bucket <bucket-name-buildpack> --region "$REGION" --create-bucket-configuration LocationConstraint="$REGION" --acl private
   aws s3api create-bucket --bucket <bucket-name-droplet>   --region "$REGION" --create-bucket-configuration LocationConstraint="$REGION" --acl private
   aws s3api create-bucket --bucket <bucket-name-package>   --region "$REGION" --create-bucket-configuration LocationConstraint="$REGION" --acl private
   aws s3api create-bucket --bucket <bucket-name-resource>  --region "$REGION" --create-bucket-configuration LocationConstraint="$REGION" --acl private
   

   Note: The name of your buckets (package_directory_key, droplet_directory_key, resource_directory_key, buildpack_directory_key) need to be globally unique! Also check your needed/supported aws_signature_version and configure it accordingly.

2. Create a dedicated user with read/write access to your buckets. When using AWS, take a look at their documentation.

3. Add the following values to your installation (keep in mind, that these values may vary when using a provider other than AWS):

   #@data/values
   ---
   blobstore:
     endpoint: https://s3.<your-region>.amazonaws.com/
     region: <your-region>
     access_key_id: <your-access-key-id>
     secret_access_key: <your-secret-access-key>
     package_directory_key: <bucket-name-package>
     droplet_directory_key: <bucket-name-droplet>
     resource_directory_key: <bucket-name-resource>
     buildpack_directory_key: <bucket-name-buildpack>
     aws_signature_version: "4"
