# Alicloud Provider
The Alicloud provider is used to interact with the
many resources supported by [Alicloud](https://www.aliyun.com). The provider needs to be configured
with the proper credentials before it can be used.
Use the navigation to the left to read about the available resources.
## Example Usage
```
# Configure the Alicloud Provider
provider "alicloud" {
access_key = "${var.access_key}"
secret_key = "${var.secret_key}"
region = "${var.region}"
2017-01-19 15:08:56 +01:00
}
# Create a web server
resource "alicloud_instance" "web" {
# cn-beijing
provider = "alicloud"

## Authentication
2017-01-19 15:08:56 +01:00
The Alicloud provider offers a flexible means of providing credentials for authentication.
2017-01-19 15:08:56 +01:00
The following methods are supported, in this order, and explained below:
- Static credentials
- Environment variables
### Static credentials ###
Static credentials can be provided by adding an `access_key` `secret_key` and `region` in-line in the
alicloud provider block:
Usage:
2017-01-19 15:08:56 +01:00
```
provider "alicloud" {
access_key = "${var.access_key}"
secret_key = "${var.secret_key}"
region = "${var.region}"
}
```
###Environment variables
You can provide your credentials via `ALICLOUD_ACCESS_KEY` and `ALICLOUD_SECRET_KEY`,
2017-01-19 15:08:56 +01:00
environment variables, representing your Alicloud Access Key and Secret Key, respectively.
`ALICLOUD_REGION` is also used, if applicable:
```
provider "alicloud" {}
```
Usage:
```
$ export ALICLOUD_ACCESS_KEY="anaccesskey"
2017-01-19 15:08:56 +01:00
$ export ALICLOUD_SECRET_KEY="asecretkey"
$ export ALICLOUD_REGION="cn-beijing"
$ terraform plan
```
## Argument Reference
The following arguments are supported:
* `access_key` - (Optional) This is the Alicloud access key. It must be provided, but
it can also be sourced from the `ALICLOUD_ACCESS_KEY` environment variable.
* `secret_key` - (Optional) This is the Alicloud secret key. It must be provided, but
it can also be sourced from the `ALICLOUD_SECRET_KEY` environment variable.
* `region` - (Required) This is the Alicloud region. It must be provided, but
it can also be sourced from the `ALICLOUD_REGION` environment variables.
## Testing
Credentials must be provided via the `ALICLOUD_ACCESS_KEY`, and `ALICLOUD_SECRET_KEY` environment variables in order to run acceptance tests.
