Operations on a blob endpoint

Description

Get, list, create, or delete blob containers.

Usage

blob_container(endpoint, ...)

## S3 method for class 'character'
blob_container(endpoint, key = NULL, token = NULL,
  sas = NULL, api_version = getOption("azure_storage_api_version"), ...)

## S3 method for class 'blob_endpoint'
blob_container(endpoint, name, ...)

## S3 method for class 'blob_container'
print(x, ...)

list_blob_containers(endpoint, ...)

## S3 method for class 'character'
list_blob_containers(endpoint, key = NULL,
  token = NULL, sas = NULL,
  api_version = getOption("azure_storage_api_version"), ...)

## S3 method for class 'blob_endpoint'
list_blob_containers(endpoint, ...)

create_blob_container(endpoint, ...)

## S3 method for class 'character'
create_blob_container(endpoint, key = NULL,
  token = NULL, sas = NULL,
  api_version = getOption("azure_storage_api_version"), ...)

## S3 method for class 'blob_container'
create_blob_container(endpoint, ...)

## S3 method for class 'blob_endpoint'
create_blob_container(endpoint, name,
  public_access = c("none", "blob", "container"), ...)

delete_blob_container(endpoint, ...)

## S3 method for class 'character'
delete_blob_container(endpoint, key = NULL,
  token = NULL, sas = NULL,
  api_version = getOption("azure_storage_api_version"), ...)

## S3 method for class 'blob_container'
delete_blob_container(endpoint, ...)

## S3 method for class 'blob_endpoint'
delete_blob_container(endpoint, name, confirm = TRUE, lease = NULL, ...)

Arguments

endpoint	Either a blob endpoint object as created by storage_endpoint, or a character string giving the URL of the endpoint.
...	Further arguments passed to lower-level functions.
key, token, sas	If an endpoint object is not supplied, authentication credentials: either an access key, an Azure Active Directory (AAD) token, or a SAS, in that order of priority. If no authentication credentials are provided, only public (anonymous) access to the share is possible.
api_version	If an endpoint object is not supplied, the storage API version to use when interacting with the host. Currently defaults to "2019-07-07".
name	The name of the blob container to get, create, or delete.
x	For the print method, a blob container object.
public_access	For creating a container, the level of public access to allow.
confirm	For deleting a container, whether to ask for confirmation.
lease	For deleting a leased container, the lease ID.

Details

You can call these functions in a couple of ways: by passing the full URL of the share, or by passing the endpoint object and the name of the container as a string.

If authenticating via AAD, you can supply the token either as a string, or as an object of class AzureToken, created via AzureRMR::get_azure_token. The latter is the recommended way of doing it, as it allows for automatic refreshing of expired tokens.

Value

For blob_container and create_blob_container, an S3 object representing an existing or created container respectively.

For list_blob_containers, a list of such objects.

Examples

## Not run: 

endp <- blob_endpoint("https://mystorage.blob.core.windows.net/", key="access_key")

# list containers
list_blob_containers(endp)

# get, create, and delete a container
blob_container(endp, "mycontainer")
create_blob_container(endp, "newcontainer")
delete_blob_container(endp, "newcontainer")

# alternative way to do the same
blob_container("https://mystorage.blob.core.windows.net/mycontainer", key="access_key")
create_blob_container("https://mystorage.blob.core.windows.net/newcontainer", key="access_key")
delete_blob_container("https://mystorage.blob.core.windows.net/newcontainer", key="access_key")

# authenticating via AAD
token <- AzureRMR::get_azure_token(resource="https://storage.azure.com/",
    tenant="myaadtenant",
    app="myappid",
    password="mypassword")
blob_container("https://mystorage.blob.core.windows.net/mycontainer", token=token)
