我有一个只包含两个文件的目录, Dockerfile
和 sayhello.sh
:
.
├── Dockerfile
└── sayhello.sh
Dockerfile
读取
FROM alpine
COPY sayhello.sh sayhello.sh
CMD ["sayhello.sh"]
和 sayhello.sh
简单地包含
echo hello
Dockerfile
构建成功:
kurtpeek@Sophiemaries-MacBook-Pro ~/d/s/trybash> docker build --tag trybash .
Sending build context to Docker daemon 3.072 kB
Step 1/3 : FROM alpine

---> fe41f2497715
Step 3/3 : CMD sayhello.sh
---> Using cache
---> dfcc26c78541
Successfully built dfcc26c78541
但是,如果我尝试 run
我得到一个 executable file not found in $PATH
错误:
kurtpeek@Sophiemaries-MacBook-Pro ~/d/s/trybash> docker run trybash
container_linux.go:247: starting container process caused "exec: \"sayhello.sh\": executable file not found in $PATH"
docker: Error response from daemon: oci runtime error: container_linux.go:247: starting container process caused "exec: \"sayhello.sh\": executable file not found in $PATH".
ERRO[0001] error getting events from daemon: net/http: request canceled
这是什么原因造成的?我记得以类似的方式在基于 debian:jessie
的图像中运行脚本。所以也许它是阿尔卑斯山特有的?

Alpine 使用 ash 作为默认 shell 而不是
bash
。这样你就可以
