我目前正在尝试为 AWS 批处理构建自定义 ubuntu ami，并遵循此处提到的文档 https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ecs-agent-install.html

但是，当我尝试在该机器上启动 docker 代理时，它总是不断给我这个错误

我确保该实例具有与之关联的 ecsInstanceRole。你们能告诉我我错过了什么吗？

不确定您是如何启动 ecs-agent 的。遇到了错误

Disabling TaskCPUMemLimit because agent is unabled to setup '/ecs cgroup: cgroup create: unable to create controller: /sys/fs/cgroup/systemd/ecs: read-only file system

我们通过将卷添加--volume=/sys/fs/cgroup:/sys/fs/cgroup:ro到我们启动 ecs 的 systemd 单元文件来解决这个问题。

除此之外，我认为问题出在ecsInstanceRole. 您可以验证它具有以下权限吗？AmazonEC2ContainerRegistryFullAccess, AmazonEC2ContainerServiceFullAccess,AmazonEC2ContainerServiceforEC2Role

以下是 ecs-agent 的完整 systemd 文件。

我遇到了同样的消息。您需要根据此文档创建 IAM 角色并使用该角色启动实例：https ://docs.aws.amazon.com/AmazonECS/latest/developerguide/launch_container_instance.html
