Running a docker Image of Golang failed, with error 'starting container process caused: exec: "/path": permission denied'
问题
我成功地从 Dockerfile 构建了一个 Go Docker 镜像，但是当我运行 docker run -p 端口:端口 --name 镜像名称 镜像ID 时，出现了 "permission denied" 错误。
这是我的 Dockerfile：
FROM golang:1.17.2-alpine3.13 as build
WORKDIR /app
COPY . .
RUN go build -o app
FROM alpine:3.7
COPY --from=build /app /usr/local/bin/go_webhooks
RUN chmod +x /usr/local/bin/go_webhooks
ENTRYPOINT ["/usr/local/bin/go_webhooks"]
我尝试使用 chmod，但仍然无法解决问题。
实际的错误消息是：
docker run -p 8000:8000 --name go_webs3 d5f30e8f9703
docker: Error response from daemon: OCI runtime create failed:
container_linux.go:380: starting container process caused: exec:
"/usr/local/bin/go_webhooks": permission denied: unknown.
ERRO[0000] error waiting for container: context canceled
英文:
I build a Go docker image from docker file successfully, but docker run -p port:port --name imagename imageid gives me permission denied error.
This is my docker file
FROM golang:1.17.2-alpine3.13 as build
WORKDIR /app
COPY . .
RUN go build -o app
FROM alpine:3.7
COPY --from=build /app /usr/local/bin/go_webhooks
RUN chmod +x /usr/local/bin/go_webhooks
ENTRYPOINT ["/usr/local/bin/go_webhooks"]
I tried using chmod but still could not solve it.
The actual error message is:
docker run -p 8000:8000 --name go_webs3 d5f30e8f9703
docker: Error response from daemon: OCI runtime create failed:
container_linux.go:380: starting container process caused: exec:
"/usr/local/bin/go_webhooks": permission denied: unknown.
ERRO[0000] error waiting for container: context canceled

过去的类似错误信息指出了一个go build的问题。
但在你的情况下，将一个文件夹复制到/usr/local/bin/go_webhooks会使go_webhooks成为一个文件夹。
WORKDIR /app
# 表示/app是一个文件夹
你不能直接执行一个文件夹。
你的入口点需要引用该文件夹内的可执行文件。
你可能需要将构建的文件复制到/app内：
COPY --from=build /app/app /usr/local/bin/go_webhooks
英文:
A past similar error message pointed out to a go build issue.
But in your case, copying a folder to /usr/local/bin/go_webhooks would make go_webhooks a folder.
WORKDIR /app
# means /app is a folder
You cannot directly execute a folder.
Your Entrypoint needs to reference an executable inside that folder.
You might needs to copy the built file inside /app:
COPY --from=build /app/app /usr/local/bin/go_webhooks
