테라폼 Auto Scaling Group 생성(+ 서버이미지 적용)

테라폼 Auto Scaling Group 생성(+ 서버이미지 적용)

테라폼 Lunch Configuration 생성

resource "ncloud_launch_configuration" "lc" {
  name = "my-lc"
  server_image_product_code = "SW.VSVR.OS.LNX64.CNTOS.0703.B050"
  server_product_code = "SVR.VSVR.HICPU.C002.M004.NET.SSD.B050.G002"
}

테라폼 Auto Scaling Group 생성

resource "ncloud_auto_scaling_group" "auto" {
  access_control_group_no_list = [ncloud_vpc.example.default_access_control_group_no]
  subnet_no = ncloud_subnet.example.subnet_no
  launch_configuration_no = ncloud_launch_configuration.lc.launch_configuration_no
  min_size = 1
  max_size = 1
}

Auto Scaling 정책 추가

resource "ncloud_auto_scaling_policy" "policy" {
  name = "my-policy"
  adjustment_type_code = "CHANG"
  scaling_adjustment = 2
  auto_scaling_group_no = ncloud_auto_scaling_group.asg.auto_scaling_group_no
}

변수들

• adjustment_type_code - (Required) Determines how the number of servers is scaled when the scaling policy is performed. Valid values are CHANG, EXACT, and PRCNT.
• scaling_adjustment - (Required) Specify the adjustment value for the adjustment type. Enter a negative value to decrease when adjustTypeCode is CHANG or PRCNT.

 

 서버이미지

member_server_image_no는 server_image_product_code 대신 사용 할 수 있다.

Auto scaling 에도 사용가능 하지만 server 만들때도 적용가능하다.

resource "ncloud_server" "server" {
  subnet_no                 = ncloud_subnet.test.id
  name                      = "my-tf-server"
  member_server_image_no    = 22863503
  login_key_name            = ncloud_login_key.loginkey.key_name
}

서버 이미지로 가능하다.
