Dockerfile : no such file or directory

Question

我做了一个 Dockerfile 来将我的开发投入生产。
但是，当我运行 docker 时，出现以下错误:

http: panic serving xxx.xxx.xxx.xxx:xxxxx: open views/public/index.html: no such file or directory

我的错误在我的 Dockerfile 中，但我看不到在哪里..
我的 Dockerfile :

FROM golang:alpine as builder
RUN apk update && apk add --no-cache git ca-certificates gcc g++ make && update-ca-certificates   
RUN adduser -D -g '' appuser   
WORKDIR /usr/src/app   
COPY . .   
RUN go mod download   
RUN go mod verify   
WORKDIR /usr/src/app/cmd/web   
RUN make docker    
FROM scratch   
WORKDIR /   
COPY --from=builder /etc/ssl/certs/ca-certificates.crt /etc/ssl/certs/   
COPY --from=builder /etc/passwd /etc/passwd   
COPY --from=builder /usr/src/app/cmd/web/web /web   
USER appuser   
ENTRYPOINT ["./web"]   
CMD [":9000"] 

我的程序中路由“/”的示例:

func (s *server) handleIndex() http.HandlerFunc {
    return func(w http.ResponseWriter, r *http.Request) {
        auth, _ := strconv.ParseBool(s.GetSessionValue(w, r, "authenticated"))
        files := []string{
            "views/public/index.html",
            "views/public/nav.html",
        }
        templates := template.Must(template.ParseFiles(files...))
        if err := templates.ExecuteTemplate(w, "index", authData{Authenticated: auth, NotAuthenticated: !auth}); err != nil {
            http.Error(w, err.Error(), http.StatusInternalServerError)
        }
    }
}

您需要将静态和 View 目录添加到最终图像中，为此在 USER appuser 之前添加以下 2 行:

COPY --from=builder /usr/src/app/cmd/web/views /web/views
COPY --from-builder /usr/src/app/cmd/web/static /web/static
