我有一个Docker文件,它完美地构建：docker build -t myfile.
但当我尝试使用docker-compose运行它时 – 它给了我一个错误：
web_1 | /bin/sh: 1: [/home/root/myproject/uwsgi.sh: not found
myproject_web_1 exited with code 127
Gracefully stopping... (press Ctrl+C again to force)
如果我手动启动此脚本 – 它工作正常.
Dockerfile看起来像：
FROM ubuntu:14.04
ADD ./myproject/ /home/root/myproject/
WORKDIR /home/root/myproject/
# Some other stuff...
CMD ['/home/root/myproject/uwsgi.sh','start' ]
泊坞窗,compose.yml：
web:
build: .
ports:
- "8888:8888"
links:
- db
db:
image: mysql
为什么我收到此错误？
谢谢.
我简化了你的例子
见https://github.com/BITPlan/docker-stackoverflowanswers/tree/master/33229581
和使用：
泊坞窗,compose.yml
web:
build: .
ports:
- "8888:8888"
找 .
.
./docker-compose.yml
./Dockerfile
./myproject
码头工作者跑
docker-compose build
docker-compose run web
当然,我明白了
/bin/sh: 1: [/home/root/myproject/uwsgi.sh,: not found
假设这是因为myproject目录中没有uwsgi.sh.
如果我添加uwsgi.sh
echo 'echo $0 is there and called with params $@!' > myproject/uwsgi.sh
chmod +x myproject/uwsgi.sh
并测试它
docker-compose run web /bin/bash
ls
cat uwsgi.sh
./uwsgi.sh start
它就在那里并按预期行事：
root@9f06f8ff8c3b:/home/root/myproject# ls
uwsgi.sh
root@9f06f8ff8c3b:/home/root/myproject# cat uwsgi.sh
echo $0 is there and called with params $@!
root@9f06f8ff8c3b:/home/root/myproject# ./uwsgi.sh start
./uwsgi.sh is there and called with params start!
root@9f06f8ff8c3b:/home/root/myproject#
但对于docker-compose运行网络,我仍然得到
/bin/sh: 1: [/home/root/myproject/uwsgi.sh,: not found
如果我向Dockerfile CMD行添加一个空格：
CMD [ '/home/root/myproject/uwsgi.sh','start' ]
结果是：
????/ bin / sh：1：[：/ home / root /myproject / uwsgi.sh,：意外的运算符
这让我们更接近.作为下一步,我将省略“start”参数.
CMD [ '/home/root/myproject/uwsgi.sh' ]
现在这导致根本没有输出……
如果我将CMD线更改为：
CMD [ "/home/root/myproject/uwsgi.sh","start" ]
我明白了
Cannot start container
0b9da138c43ef308ad70da4a7718cb96fbfdf6cda113e2ae0ce5e24de06f07cd: [8]
System error: exec format error
现在你可以继续像爱迪生一样：
我没有失败.我刚刚找到了10,000种不起作用的方法.
直到你找到
CMD [ "/bin/bash","/home/root/myproject/uwsgi.sh","start" ]
这会让你更接近结果：
/home/root/myproject/uwsgi.sh is there and called with params start!
CMD期望可执行文件作为第一个参数,例如
https://docs.docker.com/compose/
具有
CMD python app.py
举个例子.要运行shell脚本,您需要一个像bash这样的shell.
