docker: Error response from daemon: OCI runtime create failed: container_linux.go:380: starting container process caused: exec: "/start.sh": permission denied: unknown.




RUN chmod +x /start.sh
CMD ["/start.sh"]  

启动报错
docker logs my_python_http_server
standard_init_linux.go:228: exec user process caused: exec format error

start.sh  增加 #!/bin/sh


使用 CMD ["python","-m","http.server","8030"]
启动成功
http://127.0.0.1:8030/
http://127.0.0.1:8030/hello.html




几种写法

CMD ["python","-m","http.server","8030"]

# 不需要可执行权限
CMD ["sh","/start.sh"]

# 需要可执行权限 且加上 #!/bin/sh
RUN chmod +x /start.sh
CMD ["/start.sh"]
