问题描述
我收到了这个奇怪的错误信息
I'm receiving this curious error message
PlatformTaskDefinitionIncompatibilityException: 指定平台不满足任务定义所需的能力
PlatformTaskDefinitionIncompatibilityException: The specified platform does not satisfy the task definition’s required capabilities
我怀疑这与这条线有关，虽然不太确定
I suspect it's something to do with this line although not quite sure

推荐答案
您只需要将您的 ecs 服务升级到最新版本
You simply require to upgrade your ecs service to latest version
resource "aws_ecs_service" "service" {
platform_version = "1.4.0"
launch_type = "FARGATE"
...
}
efs 功能仅在最新版本中可用
efs feature is only available on the latest version
当您不指定 platform_version 时，它将默认为 LATEST，它设置为 1.3.0，不允许 efs 卷.
When you don’t specify platform_version, it will default to LATEST which is set to 1.3.0 which doesn’t allow efs volumes.
