# Azure Storage Account CORS Issues

This incident type typically refers to an issue with Cross-Origin Resource Sharing (CORS) configuration in an Azure Storage account. CORS issues can cause errors or prevent certain types of requests from being processed by the server. This can lead to disruptions in service or data access for users or applications relying on the Azure Storage account.

### Parameters

```shell
export STORAGE_ACCOUNT_NAME="PLACEHOLDER"
export STORAGE_ACCOUNT_KEY="PLACEHOLDER"
export RESOURCE_GROUP_NAME="PLACEHOLDER"
export ALLOWED_ORIGINS="PLACEHOLDER"
export METHODS="PLACEHOLDER"
```

## Debug

### List the storage accounts in the subscription

```shell
az storage account list --resource-group ${RESOURCE_GROUP_NAME}
```

### Show the details of a specific storage account

```shell
az storage account show --name ${STORAGE_ACCOUNT_NAME} --resource-group ${RESOURCE_GROUP_NAME}
```

### Check the CORS rules for a storage account

```shell
az storage cors list --account-name ${STORAGE_ACCOUNT_NAME} --account-key ${STORAGE_ACCOUNT_KEY}
```

## Repair

### Check and update the Azure storage account configuration settings to ensure that CORS is correctly configured.

```shell
#!/bin/bash

# Set the values for the following parameters
storage_account_name=${STORAGE_ACCOUNT_NAME}
storage_account_key=${STORAGE_ACCOUNT_KEY}
allowed_origins=${ALLOWED_ORIGINS}
methods=${METHODS}

# Check if CORS is enabled for the storage account
cors_enabled=$(az storage cors list--account-name $storage_account_name --account-key $storage_account_key -o tsv)

if [ -z "$cors_enabled" ]
then
    # If CORS is not enabled, enable it and set allowed origins
    az storage cors add --methods $methods --origins $allowed_origins --services bfqt
    echo "CORS has been enabled and allowed origins have been set for the storage account."
else
   # If CORS is enabled, clear existing CORS rules and then add new CORS rules
    az storage cors clear --account-name $storage_account_name --services bfqt
    az storage cors add --methods $methods --origins $allowed_origins --services bfqt
    echo "Existing CORS rules have been cleared, and new allowed origins have been set for the storage account."
fi
