# Azure Blob Storage cache storage
|
|
|
|
> **Warning**
|
|
>
|
|
> This cache backend is unreleased. You can use it today, by using the
|
|
> `moby/buildkit:master` image in your Buildx driver.
|
|
|
|
The `azblob` cache store uploads your resulting build cache to
|
|
[Azure's blob storage service](https://azure.microsoft.com/en-us/services/storage/blobs/).
|
|
|
|
> **Note**
|
|
>
|
|
> This cache storage backend requires using a different driver than the default
|
|
> `docker` driver - see more information on selecting a driver
|
|
> [here](../drivers/index.md). To create a new driver (which can act as a simple
|
|
> drop-in replacement):
|
|
>
|
|
> ```console
|
|
> docker buildx create --use --driver=docker-container
|
|
> ```
|
|
|
|
## Synopsis
|
|
|
|
```console
|
|
$ docker buildx build . --push -t <registry>/<image> \
|
|
--cache-to type=azblob,name=<cache-image>[,parameters...] \
|
|
--cache-from type=azblob,name=<cache-image>[,parameters...]
|
|
```
|
|
|
|
Common parameters:
|
|
|
|
- `name`: the name of the cache image.
|
|
- `account_url`: the base address of the blob storage account, for example:
|
|
`https://myaccount.blob.core.windows.net`. See
|
|
[authentication](#authentication).
|
|
- `secret_access_key`: specifies the
|
|
[Azure Blob Storage account key](https://docs.microsoft.com/en-us/azure/storage/common/storage-account-keys-manage),
|
|
see [authentication](#authentication).
|
|
|
|
Parameters for `--cache-to`:
|
|
|
|
- `mode`: specify cache layers to export (default: `min`), see
|
|
[cache mode](./index.md#cache-mode)
|
|
|
|
## Authentication
|
|
|
|
The `secret_access_key`, if left unspecified, is read from environment variables
|
|
on the BuildKit server following the scheme for the
|
|
[Azure Go SDK](https://docs.microsoft.com/en-us/azure/developer/go/azure-sdk-authentication).
|
|
The environment variables are read from the server, not the Buildx client.
