ContainerClient Class

Reference

A client to interact with a specific container, although that container may not yet exist.

For operations relating to a specific blob within this container, a blob client can be retrieved using the get_blob_client function.

Inheritance: azure.storage.blob._shared.base_client_async.AsyncStorageAccountHostsMixin

ContainerClient

Constructor

ContainerClient(account_url: str, container_name: str, credential: str | Dict[str, str] | AzureNamedKeyCredential | AzureSasCredential | AsyncTokenCredential | None = None, **kwargs: Any)

Parameters

Name	Description
account_url Required	str The URI to the storage account. In order to create a client given the full URI to the container, use the from_container_url classmethod.
container_name Required	str The name of the container for the blob.
credential	The credentials with which to authenticate. This is optional if the account URL already has a SAS token. The value can be a SAS token string, an instance of a AzureSasCredential or AzureNamedKeyCredential from azure.core.credentials, an account shared access key, or an instance of a TokenCredentials class from azure.identity. If the resource URI already contains a SAS token, this will be ignored in favor of an explicit credential except in the case of AzureSasCredential, where the conflicting SAS tokens will raise a ValueError. If using an instance of AzureNamedKeyCredential, "name" should be the storage account name, and "key" should be the storage account key. default value: None

Keyword-Only Parameters

Name	Description
api_version	str The Storage API version to use for requests. Default value is the most recent service version that is compatible with the current SDK. Setting to an older version may result in reduced feature compatibility. New in version 12.2.0.
secondary_hostname	str The hostname of the secondary endpoint.
max_block_size	int The maximum chunk size for uploading a block blob in chunks. Defaults to `410241024`, or 4MB.
max_single_put_size	int If the blob size is less than or equal max_single_put_size, then the blob will be uploaded with only one http PUT request. If the blob size is larger than max_single_put_size, the blob will be uploaded in chunks. Defaults to `6410241024`, or 64MB.
min_large_block_upload_threshold	int The minimum chunk size required to use the memory efficient algorithm when uploading a block blob. Defaults to `410241024`+1.
use_byte_buffer	bool Use a byte buffer for block blob uploads. Defaults to False.
max_page_size	int The maximum chunk size for uploading a page blob. Defaults to `410241024`, or 4MB.
max_single_get_size	int The maximum size for a blob to be downloaded in a single call, the exceeded part will be downloaded in chunks (could be parallel). Defaults to `3210241024`, or 32MB.

Methods

acquire_lease	Requests a new lease. If the container does not have an active lease, the Blob service creates a lease on the container and returns a new lease ID.
close	This method is to close the sockets opened by the client. It need not be used when using with a context manager.
create_container	Creates a new container under the specified account. If the container with the same name already exists, the operation fails.
delete_blob	Marks the specified blob or snapshot for deletion. The blob is later deleted during garbage collection. Note that in order to delete a blob, you must delete all of its snapshots. You can delete both at the same time with the delete_blob operation. If a delete retention policy is enabled for the service, then this operation soft deletes the blob or snapshot and retains the blob or snapshot for specified number of days. After specified number of days, blob's data is removed from the service during garbage collection. Soft deleted blobs or snapshots are accessible through list_blobs specifying include=["deleted"] Soft-deleted blob or snapshot can be restored using <xref:azure.storage.blob.aio.BlobClient.undelete>
delete_blobs	Marks the specified blobs or snapshots for deletion. The blobs are later deleted during garbage collection. Note that in order to delete blobs, you must delete all of their snapshots. You can delete both at the same time with the delete_blobs operation. If a delete retention policy is enabled for the service, then this operation soft deletes the blobs or snapshots and retains the blobs or snapshots for specified number of days. After specified number of days, blobs' data is removed from the service during garbage collection. Soft deleted blobs or snapshots are accessible through list_blobs specifying include=["deleted"] Soft-deleted blobs or snapshots can be restored using <xref:azure.storage.blob.aio.BlobClient.undelete> The maximum number of blobs that can be deleted in a single request is 256.
delete_container	Marks the specified container for deletion. The container and any blobs contained within it are later deleted during garbage collection.
download_blob	Downloads a blob to the StorageStreamDownloader. The readall() method must be used to read all the content or readinto() must be used to download the blob into a stream. Using chunks() returns an async iterator which allows the user to iterate over the content in chunks.
exists	Returns True if a container exists and returns False otherwise.
find_blobs_by_tags	Returns a generator to list the blobs under the specified container whose tags match the given search expression. The generator will lazily follow the continuation tokens returned by the service.
from_connection_string	Create ContainerClient from a Connection String.
from_container_url	Create ContainerClient from a container url.
get_account_information	Gets information related to the storage account. The information can also be retrieved if the user has a SAS to a container or blob. The keys in the returned dictionary include 'sku_name' and 'account_kind'.
get_blob_client	Get a client to interact with the specified blob. The blob need not already exist.
get_container_access_policy	Gets the permissions for the specified container. The permissions indicate whether container data may be accessed publicly.
get_container_properties	Returns all user-defined metadata and system properties for the specified container. The data returned does not include the container's list of blobs.
list_blob_names	Returns a generator to list the names of blobs under the specified container. The generator will lazily follow the continuation tokens returned by the service. Note that no additional properties or metadata will be returned when using this API. Additionally this API does not have an option to include additional blobs such as snapshots, versions, soft-deleted blobs, etc. To get any of this data, use list_blobs.
list_blobs	Returns a generator to list the blobs under the specified container. The generator will lazily follow the continuation tokens returned by the service.
set_container_access_policy	Sets the permissions for the specified container or stored access policies that may be used with Shared Access Signatures. The permissions indicate whether blobs in a container may be accessed publicly.
set_container_metadata	Sets one or more user-defined name-value pairs for the specified container. Each call to this operation replaces all existing metadata attached to the container. To remove all metadata from the container, call this operation with no metadata dict.
set_premium_page_blob_tier_blobs	Sets the page blob tiers on the blobs. This API is only supported for page blobs on premium accounts. The maximum number of blobs that can be updated in a single request is 256.
set_standard_blob_tier_blobs	This operation sets the tier on block blobs. A block blob's tier determines Hot/Cool/Archive storage type. This operation does not update the blob's ETag. The maximum number of blobs that can be updated in a single request is 256.
upload_blob	Creates a new blob from a data source with automatic chunking.
walk_blobs	Returns a generator to list the blobs under the specified container. The generator will lazily follow the continuation tokens returned by the service. This operation will list blobs in accordance with a hierarchy, as delimited by the specified delimiter character.

acquire_lease

Requests a new lease. If the container does not have an active lease, the Blob service creates a lease on the container and returns a new lease ID.

async download_blob(blob: str | BlobProperties, offset: int = None, length: int = None, *, encoding: str, **kwargs) -> StorageStreamDownloader[str]

Parameters

Name	Description
blob Required	str or BlobProperties The blob with which to interact. If specified, this value will override a blob value specified in the blob URL.

validate_content	bool If true, calculates an MD5 hash for each chunk of the blob. The storage service checks the hash of the content that has arrived with the hash that was sent. This is primarily valuable for detecting bitflips on the wire if using http instead of https, as https (the default), will already validate. Note that this MD5 hash is not stored with the blob. Also note that if enabled, the memory-efficient upload algorithm will not be used because computing the MD5 hash requires buffering entire blocks, and doing so defeats the purpose of the memory-efficient algorithm.
lease	BlobLeaseClient or str Required if the blob has an active lease. If specified, download_blob only succeeds if the blob's lease is active and matches this ID. Value can be a BlobLeaseClient object or the lease ID as a string.

etag	str An ETag value, or the wildcard character (). Used to check if the resource has changed, and act according to the condition specified by the match_condition* parameter.
match_condition	MatchConditions The match condition to use upon the etag.
if_tags_match_condition	str Specify a SQL where clause on blob tags to operate only on blob with a matching value. eg. `"\"tagname\"='my tag'"` New in version 12.4.0.
cpk	CustomerProvidedEncryptionKey Encrypts the data on the service-side with the given key. Use of customer-provided keys must be done over HTTPS. As the encryption key itself is provided in the request, a secure connection must be established to transfer the key.
max_concurrency	int The number of parallel connections with which to download.
encoding	str Encoding to decode the downloaded bytes. Default is None, i.e. no decoding.
progress_hook	Callable[[int, int], Awaitable[None]] An async callback to track the progress of a long running download. The signature is function(current: int, total: int) where current is the number of bytes transferred so far, and total is the total size of the download.
timeout	int Sets the server-side timeout for the operation in seconds. For more details see https://learn.microsoft.com/rest/api/storageservices/setting-timeouts-for-blob-service-operations. This value is not tracked or validated on the client. To configure client-side network timesouts see here.

Parameters

Name	Description
name Required	str or BlobProperties The blob with which to interact. If specified, this value will override a blob value specified in the blob URL.
data Required	The blob data to upload.
blob_type Required	BlobType The type of the blob. This can be either BlockBlob, PageBlob or AppendBlob. The default value is BlockBlob.
length Required	int Number of bytes to read from the stream. This is optional, but should be supplied for optimal performance.
metadata Required	dict(str, str) Name-value pairs associated with the blob as metadata.

Keyword-Only Parameters

Name	Description
overwrite	bool Whether the blob to be uploaded should overwrite the current data. If True, upload_blob will overwrite the existing data. If set to False, the operation will fail with ResourceExistsError. The exception to the above is with Append blob types: if set to False and the data already exists, an error will not be raised and the data will be appended to the existing blob. If set overwrite=True, then the existing append blob will be deleted, and a new one created. Defaults to False.
content_settings	ContentSettings ContentSettings object used to set blob properties. Used to set content type, encoding, language, disposition, md5, and cache control.
validate_content	bool If true, calculates an MD5 hash for each chunk of the blob. The storage service checks the hash of the content that has arrived with the hash that was sent. This is primarily valuable for detecting bitflips on the wire if using http instead of https, as https (the default), will already validate. Note that this MD5 hash is not stored with the blob. Also note that if enabled, the memory-efficient upload algorithm will not be used, because computing the MD5 hash requires buffering entire blocks, and doing so defeats the purpose of the memory-efficient algorithm.
lease	BlobLeaseClient or str Required if the container has an active lease. Value can be a BlobLeaseClient object or the lease ID as a string.
if_modified_since	datetime A DateTime value. Azure expects the date value passed in to be UTC. If timezone is included, any non-UTC datetimes will be converted to UTC. If a date is passed in without timezone info, it is assumed to be UTC. Specify this header to perform the operation only if the resource has been modified since the specified time.
if_unmodified_since	datetime A DateTime value. Azure expects the date value passed in to be UTC. If timezone is included, any non-UTC datetimes will be converted to UTC. If a date is passed in without timezone info, it is assumed to be UTC. Specify this header to perform the operation only if the resource has not been modified since the specified date/time.
etag	str An ETag value, or the wildcard character (). Used to check if the resource has changed, and act according to the condition specified by the match_condition* parameter.
match_condition	MatchConditions The match condition to use upon the etag.
if_tags_match_condition	str Specify a SQL where clause on blob tags to operate only on blob with a matching value. eg. `"\"tagname\"='my tag'"` New in version 12.4.0.
timeout	int Sets the server-side timeout for the operation in seconds. For more details see https://learn.microsoft.com/rest/api/storageservices/setting-timeouts-for-blob-service-operations. This value is not tracked or validated on the client. To configure client-side network timesouts see here. This method may make multiple calls to the service and the timeout will apply to each call individually. multiple calls to the Azure service and the timeout will apply to each call individually.
premium_page_blob_tier	PremiumPageBlobTier A page blob tier value to set the blob to. The tier correlates to the size of the blob and number of allowed IOPS. This is only applicable to page blobs on premium storage accounts.
standard_blob_tier	StandardBlobTier A standard blob tier value to set the blob to. For this version of the library, this is only applicable to block blobs on standard storage accounts.
maxsize_condition	int Optional conditional header. The max length in bytes permitted for the append blob. If the Append Block operation would cause the blob to exceed that limit or if the blob size is already greater than the value specified in this header, the request will fail with MaxBlobSizeConditionNotMet error (HTTP status code 412 - Precondition Failed).
max_concurrency	int Maximum number of parallel connections to use when the blob size exceeds 64MB.
cpk	CustomerProvidedEncryptionKey Encrypts the data on the service-side with the given key. Use of customer-provided keys must be done over HTTPS. As the encryption key itself is provided in the request, a secure connection must be established to transfer the key.
encryption_scope	str A predefined encryption scope used to encrypt the data on the service. An encryption scope can be created using the Management API and referenced here by name. If a default encryption scope has been defined at the container, this value will override it if the container-level scope is configured to allow overrides. Otherwise an error will be raised. New in version 12.2.0.
encoding	str Defaults to UTF-8.
progress_hook	Callable[[int, Optional[int]], Awaitable[None]] An async callback to track the progress of a long running upload. The signature is function(current: int, total: Optional[int]) where current is the number of bytes transferred so far, and total is the size of the blob or None if the size is unknown.

Returns

Type	Description
BlobClient	A BlobClient to interact with the newly uploaded blob.

walk_blobs

Returns a generator to list the blobs under the specified container. The generator will lazily follow the continuation tokens returned by the service. This operation will list blobs in accordance with a hierarchy, as delimited by the specified delimiter character.
