[AndriiAndrus]

Hi there, i've tried multiple solutions and none of them helped. Can not build my project:

# Dockerfile (builder)
FROM gcr.io/gcp-runtimes/go1-builder:1.14 as builder
WORKDIR /root/go/src/app/src/github.com/AndriiAndrus/GoWebsite
COPY . .
RUN GO111MODULE=on GOOS=linux GOARCH=amd64 /usr/local/go/bin/go build -o app .

Fails with multiple "permission denied":
