AWS Autoscaling Group:無效的隊列配置錯誤
使用 Terraform 在 AWS 中創建 Autoscaling Group。
mixed_instances_policy
在aws_autoscaling_group
Terraform 的資源中使用。resource "aws_launch_template" "go_app" { image_id = "${data.aws_ami.go_app.id}" instance_type = "${var.launch_config["instance_type"]}" vpc_security_group_ids = ["${aws_security_group.go_app.id}"] key_name = "${var.key_name}" }
啟動
instance_type
模板是.t2.small
resource "aws_autoscaling_group" "go_app" { name = "${aws_launch_template.go_app.name}-asg" vpc_zone_identifier = ["${aws_subnet.public.*.id}"] min_size = 1 desired_capacity = 2 max_size = 4 mixed_instances_policy { launch_template { launch_template_specification { launch_template_id = "${aws_launch_template.go_app.id}" version = "$$Latest" } override { instance_type = "t2.micro" } override { instance_type = "t2.nano" } } instances_distribution { on_demand_base_capacity = 1 on_demand_percentage_above_base_capacity = 0 spot_allocation_strategy = "lowest-price" spot_instance_pools = 2 } } }
這應該創建 1 個按需實例和 1 個 Spot 實例(所需容量為 2)。但它會創建 1 個按需實例,但無法創建 Spot 實例。
AutoScaling 組的 Activity History 提到 AutoScaling 組嘗試創建實例但由於以下錯誤而失敗:
Launching a new EC2 instance. Status Reason: Invalid fleet configuration. Overrides t2.nano, us-west-2c, LINUX. Launching EC2 instance failed.
該
Invalid fleet configuration. Overrides t2.nano
錯誤消息表示該t2.nano
實例類型不是該區域中支持的 Spot 實例類型。查看Spot 實例顧問以了解支持的實例類型。
