Nico Berlee c24e387462 Dockerfiles for Alpine 3.8/edge build with Nginx 1.14/1.15 (stable/mainline), (directory structure organised for DockerHub build compatibility). (#1598)
Alpine Linux is a security-oriented, lightweight Linux distribution based on musl libc and busy box. Alpine is therefor the most logical OS base for Docker Images.

Although it does not fix #1181 completely, it helps to overcome the problems of building the PSOL on Alpine,
