Use [Azure Blob Storage](https://azure.microsoft.com/products/storage/blobs)as the object store for your InfluxDB 3 Core instance.

## Object store requirements

InfluxDB 3 Core depends on strict object store consistency semantics—
strong read-after-write and list-after-write consistency, and conditional PUT
(PUT-if-not-exists) support.
Your Azure Blob Storage container must provide these semantics.
See [Object store requirements](../#object-store-requirements) for the full
list of semantics InfluxDB 3 Core depends on and how to verify your
object store meets them.

## Create a storage container

InfluxDB 3 Core stores data in a container within an existing Azure
Storage account. If you don’t already have a storage account, create one
first.

1. Sign in to the [Azure portal](https://portal.azure.com) and go to your
   storage account.
2. Under **Data storage**, click **Containers**, and then click**+ Container**.
3. Enter a container name–for example, `influxdb3`–and click **Create**.

Alternatively, use the[Azure CLI](https://learn.microsoft.com/cli/azure/storage/container) to
create a container:

```bash
az storage container create \
  --name influxdb3 \
  --account-name AZURE_STORAGE_ACCOUNT
```

## Get your storage account access key

InfluxDB 3 Core authenticates to Azure Blob Storage with your storage
account name and one of its access keys.

1. In the Azure portal, go to your storage account.
2. Under **Security + networking**, click **Access keys**.
3. Copy the storage account **name** and one of the **Key** values–you
   provide both to configure InfluxDB 3 Core.

> [!Tip]
> In production, prefer[Azure Workload Identity](https://learn.microsoft.com/azure/aks/workload-identity-overview)over a static access key where your deployment environment supports it.

## Configure InfluxDB to connect to Azure Blob Storage

To use your Azure container as the object store for your InfluxDB 3 Core
instance, provide the following options or environment variables with the`influxdb3 serve` command. The `--bucket` option specifies your Azure
container name.

#### Command options ####

* `--node-id`: Your InfluxDB 3 Core node ID (`INFLUXDB_NODE_ID`)
* `--object-store`: `azure`
* `--bucket`: `influxdb3` (your container name)
* `--azure-storage-account`: Your storage account name (`AZURE_STORAGE_ACCOUNT`)
* `--azure-storage-access-key`: One of your storage account’s access keys (`AZURE_STORAGE_ACCESS_KEY`)

```
influxdb3 serve \

--node-id INFLUXDB_NODE_ID \
  --object-store azure \
  --bucket influxdb3 \
  --azure-storage-account AZURE_STORAGE_ACCOUNT \
  --azure-storage-access-key AZURE_STORAGE_ACCESS_KEY
```

* `INFLUXDB3_NODE_ID`: Your InfluxDB 3 Core node ID (`INFLUXDB_NODE_ID`)
* `INFLUXDB3_OBJECT_STORE`: `azure`
* `INFLUXDB3_BUCKET`: `influxdb3` (your container name)
* `AZURE_STORAGE_ACCOUNT`: Your storage account name
* `AZURE_STORAGE_ACCESS_KEY`: One of your storage account’s access keys

```

export INFLUXDB3_NODE_ID=INFLUXDB_NODE_ID
export INFLUXDB3_OBJECT_STORE=azure
export INFLUXDB3_BUCKET=influxdb3
export AZURE_STORAGE_ACCOUNT=AZURE_STORAGE_ACCOUNT
export AZURE_STORAGE_ACCESS_KEY=AZURE_STORAGE_ACCESS_KEY

influxdb3 serve
```

## Confirm the object store is working

When InfluxDB 3 Core starts, it seeds your Azure container with the
necessary directory structure and begins storing data there. Confirm the
object store is functioning properly:

1. View the `influxdb3 serve` log output to confirm that the server is
   running correctly.

2. Inspect the contents of your container to confirm the necessary
   directory structure is created–for example, using the Azure CLI:

   ```
   az storage blob list \
     --container-name influxdb3 \
     --account-name AZURE_STORAGE_ACCOUNT \
     --output table
   ```
