大厅启动容器失败：从管道获取最终 child 的 pid 导致：EOF

Question

• 环境：亚马逊 linux2
• 内核版本：4.14.198-152.320.amzn2.x86_64
• 大厅version:v6.6.0
• 问题：

在 amazon 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： 运行c 运行：退出状态 1：container_linux.go：367：启动容器进程导致：process_linux.go：338：获取最终 child来自管道的 pid 导致：EOF

Answer 1

我发现根本原因是系统缺少一些工具。我用新的系统映像替换它，然后工作正常。
