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 "alicloudoss" { access_key = "abcd1234" secret_key = "defg5678" endpoint = "https://oss-us-west-1.aliyuncs.com" bucket = "my-bucket" } ``` ## `alicloudoss` parameters - `bucket` `(string: )` – Specifies the name of the OSS bucket. This can also be provided via the environment variable `ALICLOUD_OSS_BUCKET`. - `endpoint` `(string: "")` – Specifies the OSS endpoint. This can also be provided via the environment variable `ALICLOUD_OSS_ENDPOINT`. By default, the Aliyun SDK uses HTTP for endpoint schemas. **You must use the `https://` prefix to ensure encrypted communication**. The following settings are used for authenticating to Alicloud. - `access_key` – Specifies the Alicloud access key. This can also be provided via the environment variable `ALICLOUD_ACCESS_KEY`. - `secret_key` – Specifies the Alicloud secret key. This can also be provided via the environment variable `ALICLOUD_SECRET_KEY`. - `max_parallel` `(string: "128")` – Specifies the maximum number of concurrent requests to Alicloud OSS. ## `alicloudoss` examples ### Default example This example shows using Alicloud OSS as a storage backend. ```hcl storage "alicloudoss" { access_key = "abcd1234" secret_key = "defg5678" endpoint = "https://oss-us-west-1.aliyuncs.com" bucket = "my-bucket" } ``` [alicloudoss]: https://www.alibabacloud.com/product/oss
