+# huaweicloud_cae_timer_rule
+
+Use this resource to manage a timer rule for starting and stopping components within HuaweiCloud.
+
+## Example Usage
+
+```hcl
+variable "environment_id" {}
+variable "rule_name" {}
+variable "cron" {}
+variable "component_configurations" {
+  type = list(object({
+    id   = string
+    name = string
+  }))
+}
+
+resource "huaweicloud_cae_timer_rule" "test" {
+  environment_id   = var.environment_id
+  name             = var.rule_name
+  type             = "start"
+  status           = "on"
+  effective_range  = "component"
+  effective_policy = "onetime"
+  cron             =  var.cron
+
+  dynamic "components" {
+    for_each = var.component_configurations
+    content {
+      id   = components.value["id"]
+      name = components.value["name"]
+    }
+  }
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `region` - (Optional, String, ForceNew) Specifies the region in which to create the resource.
+  If omitted, the provider-level region will be used.
+  Changing this creates a new resource.
+
+* `environment_id` - (Required, String, ForceNew) Specifies the ID of the CAE environment.
+  Changing this creates a new resource.
+
+* `name` - (Required, String) Specifies the name of the timer rule.  
+  The maximum length of the name is `64` characters, only letters, digits, underscores (_) and hyphens (-)
+  are allowed.  
+  The name must start and end with a letter or a digit.
+
+* `type` - (Required, String) Specifies the type of the timer rule.  
+  The valid values are as follows:
+  + **stop**: The components will be started in batches. The components that have been started are not affected.
+  + **start**: The components will be stopped in batches. The components that have been stopped are not affected.
+
+* `status` - (Required, String) Specifies the status of the timer rule.  
+  The valid values are as follows:
+  + **on**
+  + **off**
+
+* `effective_range` - (Required, String) Specifies the effective range of the timer rule.  
+  The valid values are as follows:
+  + **environment**: The rule takes effect for all components in the environment.
+  + **application**: The rule takes effect for all components in the application.
+  + **component**: The rule takes effect for the specified components.
+
+* `effective_policy` - (Required, String) Specifies the effective policy of the timer rule.  
+  The valid values are as follows:
+  + **onetime**: The rule is executed only once.
+  + **periodic**: The rule is executed periodically.
+
+* `cron` - (Required, String) Specifies the cron expression of the timer rule.  
+  The triggered time of the rule must be at least two minutes later than the current time.  
+  When `effective_policy` is set to **periodic**, the rule can only be executed by week of day.
+
+* `applications` - (Optional, List) Specifies the list of the applications in which the timer rule takes effect.  
+  The [applications](#timer_rule_applications) structure is documented below.  
+  This parameter is required and available only when the `effective_range` parameter is set to **application**.
+
+* `components` - (Optional, List) Specifies the list of the components in which the timer rule takes effect.  
+  The [components](#timer_rule_components) structure is documented below.  
+  This parameter is required and available only when the `effective_range` parameter is set to **component**.
+
+<a name="timer_rule_applications"></a>
+The `applications` block supports:
+
+* `id` - (Required, String) Specifies the ID of the application.
+
+* `name` - (Optional, String) Specifies the name of the application.
+
+<a name="timer_rule_components"></a>
+The `components` block supports:
+
+* `id` - (Required, String) Specifies the ID of the component.
+
+* `name` - (Optional, String) Specifies the name of the component.
+
+## Attribute Reference
+
+In addition to all arguments above, the following attributes are exported:
+
+* `id` - The resource ID.
+
+## Import
+
+The resource can be imported using `environment_id` and `name`, separated by slashes (/), e.g.
+
+```bash
+$ terraform import huaweicloud_cae_timer_rule.test <environment_id>/<name>
+```
+
+Note that the imported state may not be identical to your resource definition, due to some attributes missing from the
+API response, security or some other reason.
+The missing attributes include: `status`.
+It is generally recommended running `terraform plan` after importing the resource.
+You can then decide if changes should be applied to the resource, or the resource definition should be updated to
+align with the resource. Also you can ignore changes as below.
+
+```hcl
+resource "huaweicloud_cae_timer_rule" "test" {
+  ...
+
+  lifecycle {
+    ignore_changes = [
+      status,
+    ]
+  }
+}
+```
