如何在Alpine Docker容器中运行Bash脚本?
发布于 2021-02-01 13:01:28
我的目录仅包含两个文件,Dockerfile
并且sayhello.sh
:
.
├── Dockerfile
└── sayhello.sh
在Dockerfile
读
FROM alpine
COPY sayhello.sh sayhello.sh
CMD ["sayhello.sh"]
并且sayhello.sh
仅包含
echo hello
在Dockerfile
成功生成:
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
---> 665ffb03bfae
Step 2/3 : COPY sayhello.sh sayhello.sh
---> Using cache
---> fe41f2497715
Step 3/3 : CMD sayhello.sh
---> Using cache
---> dfcc26c78541
Successfully built dfcc26c78541
但是,如果尝试run
这样做,则会executable file not found in $PATH
出现错误:
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
是什么原因造成的?(我记得debian:jessie
以类似的方式在基于图像的脚本中运行脚本,所以也许它是Alpine特有的)?
