alicloud_slb_rule_Terraform(Terraform)-阿里云帮助中心

Provides a Lindorm Instance resource.

For information about Load Balancer Forwarding Rule and how to use it, see What is Rule.

-> NOTE: Available since v1.6.0.

A forwarding rule is configured in HTTP/HTTPS listener and it used to listen a list of backend servers which in one specified virtual backend server group. You can add forwarding rules to a listener to forward requests based on the domain names or the URL in the request.

-> NOTE: One virtual backend server group can be attached in multiple forwarding rules.

-> NOTE: At least one "Domain" or "Url" must be specified when creating a new rule.

-> NOTE: Having the same 'Domain' and 'Url' rule can not be created repeatedly in the one listener.

-> NOTE: Rule only be created in the HTTP or HTTPS listener.

-> NOTE: Only rule's virtual server group can be modified.

Argument Reference

The following arguments are supported:

load_balancer_id - (Required, ForceNew) The Load Balancer ID which is used to launch the new forwarding rule.
name - (Optional) Name of the forwarding rule. Our plugin provides a default name: "tf-slb-rule".
frontend_port - (Required, Int, ForceNew) The listener frontend port which is used to launch the new forwarding rule. Valid values: [1-65535].
domain - (Optional, ForceNew) Domain name of the forwarding rule. It can contain letters a-z, numbers 0-9, hyphens (-), and periods (.), and wildcard characters. The following two domain name formats are supported:
- Standard domain name: www.test.com
- Wildcard domain name: .test.com. wildcard () must be the first character in the format of (*.)
url - (Optional, ForceNew) Domain of the forwarding rule. It must be 2-80 characters in length. Only letters a-z, numbers 0-9, and characters '-' '/' '?' '%' '#' and '&' are allowed. URLs must be started with the character '/', but cannot be '/' alone.
server_group_id - (Required) ID of a virtual server group that will be forwarded.
scheduler - (Optional, Available since v1.51.0) Scheduling algorithm. Valid values: wrr, rr and wlc. Default value: wrr. NOTE: scheduler is required and takes effect only when listener_sync is set to off.
sticky_session - (Optional, Available since v1.51.0) Whether to enable session persistence. Valid values: on and off. Default value: off. NOTE: sticky_session is required and takes effect only when listener_sync is set to off.
sticky_session_type - (Optional, Available since v1.51.0) Mode for handling the cookie. If sticky_session is on, it is mandatory. Otherwise, it will be ignored. Valid values: insert and server. insert means it is inserted from Server Load Balancer; server means the Server Load Balancer learns from the backend server.
cookie_timeout - (Optional, Int, Available since v1.51.0) Cookie timeout. It is mandatory when sticky_session is on and sticky_session_type is insert. Otherwise, it will be ignored. Valid values: [1-86400] in seconds.
cookie - (Optional, Available since v1.51.0) The cookie configured on the server. It is mandatory when sticky_session is on and sticky_session_type is server. Otherwise, it will be ignored. Valid value：String in line with RFC 2965, with length being 1 - 200. It only contains characters such as ASCII codes, English letters and digits instead of the comma, semicolon or spacing, and it cannot start with $.
health_check - (Optional, Available since v1.51.0) Whether to enable health check. Valid values: on and off. TCP and UDP listener's health_check is always on, so it will be ignore when launching TCP or UDP listener. NOTE: health_check is required and takes effect only when listener_sync is set to off.
health_check_domain - (Optional, Available since v1.51.0) Domain name used for health check. When it used to launch TCP listener, health_check_type must be http. Its length is limited to 1-80 and only characters such as letters, digits, ‘-‘ and ‘.’ are allowed. When it is not set or empty, Server Load Balancer uses the private network IP address of each backend server as Domain used for health check.
health_check_uri - (Optional, Available since v1.51.0) URI used for health check. When it used to launch TCP listener, health_check_type must be http. Its length is limited to 1-80 and it must start with /. Only characters such as letters, digits, ‘-’, ‘/’, ‘.’, ‘%’, ‘?’, #’ and ‘&’ are allowed.
health_check_connect_port - (Optional, Int, Available since v1.51.0) Port used for health check. Valid values: [1-65535]. Default value: None means the backend server port is used.
healthy_threshold - (Optional, Available since v1.51.0) Threshold determining the result of the health check is success. It is required when health_check is on. Valid values: [1-10] in seconds. Default value: 3.
unhealthy_threshold - (Optional, Int, Available since v1.51.0) Threshold determining the result of the health check is fail. It is required when health_check is on. Valid values: [1-10] in seconds. Default value: 3.
health_check_timeout - (Optional, Int, Available since v1.51.0) Maximum timeout of each health check response. It is required when health_check is on. Valid values: [1-300] in seconds. Default value: 5. Note: If health_check_timeout < health_check_interval, its will be replaced by health_check_interval.
health_check_interval - (Optional, Int, Int, Available since v1.51.0) Time interval of health checks. It is required when health_check is on. Valid values: [1-50] in seconds. Default value: 2.
health_check_http_code - (Optional, Available since v1.51.0) Regular health check HTTP status code. Multiple codes are segmented by “,”. It is required when health_check is on. Default value: http_2xx. Valid values: http_2xx, http_3xx, http_4xx and http_5xx.
listener_sync - (Optional, Available since v1.51.0) Indicates whether a forwarding rule inherits the settings of a health check , session persistence, and scheduling algorithm from a listener. Default value: on. Valid values: on and off.
delete_protection_validation - (Optional, Bool, Available since v1.63.0) Checking DeleteProtection of SLB instance before deleting. If true, this resource will not be deleted when its SLB instance enabled DeleteProtection. Default value: false.

Attributes Reference

The following attributes are exported:

id - The resource ID in terraform of Rule.
