The storage container must already exist and the provided account credentials must have read and write permissions to the storage container. - **No High Availability** – the Azure storage backend does not support high availability. - **Community Supported** – the Azure storage backend is supported by the community. While it has undergone review by HashiCorp employees, they may not be as knowledgeable about the technology. If you encounter problems with them, you may be referred to the original author. ```hcl storage "azure" { accountName = "my-storage-account" accountKey = "abcd1234" container = "container-efgh5678" environment = "AzurePublicCloud" } ``` The current implementation is limited to a maximum of 4 megabytes per blob. ## `azure` Parameters - `accountName` `(string: )` – Specifies the Azure Storage account name. - `accountKey` `(string: )` – Specifies the Azure Storage account key. - `container` `(string: )` – Specifies the Azure Storage Blob container name. - `environment` `(string: "AzurePublicCloud")` - Specifies the cloud environment the storage account belongs to by way of the case-insensitive name defined in the [Azure Go SDK][azure-environment]. - `max_parallel` `(string: "128")` – Specifies The maximum number of concurrent requests to Azure. ## `azure` Examples This example shows configuring the Azure storage backend with a custom number of maximum parallel connections. ```hcl storage "azure" { accountName = "my-storage-account" accountKey = "abcd1234" container = "container-efgh5678" max_parallel = 512 } ``` [azure-storage]: https://azure.microsoft.com/en-us/services/storage/ [azure-environment]: https://godoc.org/github.com/Azure/go-autorest/autorest/azure#pkg-variables
