大厅启动容器失败：从管道获取最后一个孩子的 pid 导致：EOF

Question

• 环境：amazon linux2
• 内核版本：4.14.198-152.320.amzn2.x86_64
• 大厅版本：v6.6.0
• 问题：

在亚马逊 EC2 上设置 concourse 后，我可以登录 concourse web 并创建管道。但是当我触发管道构建时，我收到以下错误消息： runc run：退出状态1：container_linux.go:367：启动容器进程导致：process_linux.go:338：从管道获取最终子进程的pid导致：EOF

• 检查后端日志：

Answer 1

我发现根本原因是系统缺少一些工具。我使用新的系统映像替换它，然后工作正常。
