The backend.dockerfile is:

FROM golang:1.15-alpine

RUN apk add --no-cache git
WORKDIR /go/src/app
COPY src/*.go ./
COPY src/*.htm ./
COPY src/static/*.css ./static/
COPY src/static/*.png ./static/
COPY src/static/cover/*.jpg ./static/cover/

RUN go get -d -v ./...
RUN go install -v ./...

CMD ["app"]

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"]
