Details and Options

  • ExternalStorageUpload returns an ExternalStorageObject.
  • The default external storage is given by $ExternalStorageBase.
  • Possible forms for dest include:
  • "path"path in the external storage service (e.g. Dropbox)
    "bucket"bucket name in the external storage service (e.g. Amazon S3)
    "bucket/key"bucket name and key in the external storage service (e.g. Amazon S3)
    "bucket/prefix/"bucket name and prefix in the external storage service (e.g. Amazon S3)
    "uri"external storage service URI (e.g. Amazon S3 URI)
    {"dest1","dest2",…}list of paths, buckets or URIs in the external storage service

IPFS  (1)

Upload a file to the InterPlanetary File System (IPFS). IPFS does not require a target path because files in that system are identified by a content identifier (CID) that is automatically provided:

OverwriteTarget  (1)

By default, ExternalStorageUpload does not overwrite a file if a different file is uploaded to an existing path. Upload a new file:

Upload a new file to the same path:

A new file will be created:

By setting the OverwriteTarget option to True, the target file will be replaced:

Properties & Relations  (2)

The ExternalStorageBase option can use a ServiceObject as a value, from an already created connection:

CopyFile also supports an ExternalStorageObject as a file specification to upload a local file to an external storage service:

Possible Issues  (1)

IPFS manages the content identifier (CID):

With IPFS, you cannot upload to a specific ExternalStorageObject:
