[k8s]docker entrypoint图解

docker entry 实验

[root@lanny centos]# cat docker-entrypoint.sh 
#!/bin/bash

echo "第一个参数: $1"
echo "第二个参数: $2"
echo "总共参数: $#"
echo "脚本名字: $0"

1.ENTRYPOINT结合CMD

FROM centos

COPY docker-entrypoint.sh /bin/
ENTRYPOINT ["docker-entrypoint.sh"]

CMD [ "ls" ]

2.

[root@lanny centos]# cat Dockerfile 
FROM centos


COPY docker-entrypoint.sh /bin/
ENTRYPOINT ["docker-entrypoint.sh","ls"]

docker run报错解决: dos2unix

panic: standard_init_linux.go:178: exec user process caused "no such file or directory"
