Golang docker 容器无法在 Windows Home 上启动

Question

我正在使用在 Docker 中启用了 WSL 的 Windows Home OS。

打印下面的构建消息后

docker build .

SECURITY WARNING: You are building a Docker image from Windows against a non-    Windows Docker host. All files and directories added to build context will have '-rwxr-    xr-x' permissions. It is recommended to double check and reset permissions for sensitive files and directories.

当我尝试运行下面的图像消息时打印

docker run 49fee6f5a6bb -d

docker: Error response from daemon: OCI runtime create failed: container_linux.go:349: starting container process caused "exec: \"-d\": executable file not found in $PATH": unknown.

Dockerfile 内容如下

FROM golang:alpine

# Set necessary environmet variables needed for our image

ENV GO111MODULE=on \

    CGO_ENABLED=0 \

    GOOS=linux \

    GOARCH=amd64

# Move to working directory /build

WORKDIR /build

# Copy and download dependency using go mod

COPY go.mod .

COPY go.sum .

RUN go mod download

# Copy the code into the container

COPY . .

# Build the application

RUN go build -o main .

# Move to /dist directory as the place for resulting binary folder

WORKDIR /dist

# Copy binary from build to main folder

RUN cp /build/main .

# Export necessary port

EXPOSE 3000

# Command to run when starting the container

CMD ["/dist/main"]

问题是命令的顺序（很可能）：docker run -d yourcontainer应该管用一些不相关的建议：这是对您的 docker 文件的重写（未经测试）。如您所见，它更短，并且使用构建和运行阶段。FROM alpine:latest构建阶段使用一个更大的容器，里面有golang 、你的代码等。运行容器（例如，仅使用您的代码来强化 linux）。FROM golang:alpine AS buildWORKDIR /buildADD . /build# Depending on the golang version GO111MODULE can be removed as env variableRUN GOOS=linux GOARCH=amd64 GO111MODULE=on go build -o main FROM alpine:latest# Export necessary portEXPOSE 3000# Add  applicationWORKDIR /distCOPY --from=build /build/main /dist/main
