Try to use this version
FROM golang:1.17-alpine as build-env
# Set environment variable
ENV APP_NAME app
ENV CMD_PATH main.go
RUN apk add --no-cache git
WORKDIR $GOPATH/src/$APP_NAME
COPY src/*.go ./
COPY src/*.htm ./
COPY src/static/*.css ./static/
COPY src/static/*.png ./static/
COPY src/static/cover/*.jpg ./static/cover/
# Run Stage
FROM alpine:3.14
# Set environment variable
ENV APP_NAME app
# Copy only required data into this image
COPY --from=build-env /$APP_NAME .
RUN go get -d -v ./...
RUN go install -v ./...
EXPOSE 8081
CMD ["app"]
