Golang Dockerfile 权限被拒绝

Question

我的 Dockerfile 上的权限分配似乎有错误，我似乎无法解决它。

这是错误

Error response from daemon: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: exec: "/my-app": permission denied: unknown

这是我的 Dockerfile

# syntax=docker/dockerfile:1

##

## Build

##

FROM golang:1.19rc2-buster AS build

WORKDIR /app

COPY src/go.mod ./

COPY src/go.sum ./

RUN go mod download

COPY src/*.go ./

RUN go build -o /my-app

##

## Deploy

##

FROM gcr.io/distroless/base-debian10

WORKDIR /

COPY --from=build /my-app /my-app

USER nonroot:nonroot

ENTRYPOINT ["/my-app"]

这是我的 docker-compose

version: "3.7"

      dockerfile: go.Dockerfile
