amazon-web-services - 容器 ECS EC2 未以`running exec setns process for init 开头导致 \"exit status 23\"": unknown`

问题描述

尝试在支持 EC2 的 AWS ECS 上运行 hello-world 容器时出现以下错误：

CannotStartContainerError: Error response from daemon: OCI runtime create failed: container_linux.go:348: starting container process caused "process_linux.go:301: running exec setns process for init caused \"exit status 23\"": unknown

我的 dockerfile 看起来像：

FROM ubuntu:18.04

# Install dependencies
RUN apt-get update && \
 apt-get -y install apache2

# Install apache and write hello world message
RUN echo 'Hello World!' > /var/www/html/index.html

# Configure apache
RUN echo '. /etc/apache2/envvars' > /root/run_apache.sh && \
 echo 'mkdir -p /var/run/apache2' >> /root/run_apache.sh && \
 echo 'mkdir -p /var/lock/apache2' >> /root/run_apache.sh && \ 
 echo '/usr/sbin/apache2 -D FOREGROUND' >> /root/run_apache.sh && \ 
 chmod 755 /root/run_apache.sh

EXPOSE 80

CMD /root/run_apache.sh

和我的任务定义：

容器实例是：

Agent version  1.30.0
Docker version  18.06.1-ce

有什么想法可以解决或调试这个问题吗？谢谢

解决方案

我从工作任务定义向后工作，罪魁祸首原来是"memory": "4",

将此更改为"memory": "256"，导致任务成功启动。
