Problem to git clone (permission issue) and сonnection problem to postgres (no connect db postgres)

Greetings! Sorry for my english.
Need your help. Spent many hours disassembling docker, specifically for Windows 10 (this is hell, but windows are needed).
My client docker: Windows Desktop last, download off site.

Need an image for web:

-Php 7.2-fpm-alpine
-Nginx:alpine
-Postgres10.1-alpine
-Composer
-Node10.2-alpine
-Git

I downloaded the necessary software, cloned the project, recorded the database, created commands for composer (composer install, update) and node (npm install, update).

All this on windows10pro-> alpine. Nginx + php + composer + nodejs is already working, the rest is not.

There is a problem with docker - git clone (.ssh-key), postgres (db: postgres) os alpine. To be precise with the rights for git and the test base is not connected.

Error:

Git: He set permissions in different ways - chmod, created docker-entrypoint.sh, volume on .ssh. In general, nothing helps. The project does not clone, ssh matches host (win10) / docker (alpine) введите сюда описание изображения

Postgres: db no default is created, although environment is spelled correctly. I registered in the Dockerfile itself, but it did not lead to success. It is necessary that the database is stored on my container and at startup.

My docker-composer:

version: '3.7'

My dockerfile php:

   FROM php:7.2-fpm-alpine

   USER root

   #COPY docker-entrypoint.sh /bin/docker-entrypoint.sh
   #RUN chmod +x /bin/docker-entrypoint.sh
   #ENTRYPOINT ["/bin/docker-entrypoint.sh"]

   RUN apk --update add ca-certificates \
       && apk add -U \
       # Packages ./.   git \
       openssh \    # Clean up
       && rm -rf /var/cache/apk/*

   VOLUME /var/www   VOLUME /root/.ssh

   # Clone a repository (my website in this case) git clone git@github.com:user/rep

Dockerfile postgres:

   FROM postgres:10.1-alpine

   VOLUME /var/lib/postgresql/data

   EXPOSE 5432

Help, if anyone has encountered this problem and has experience docker on windows 10 pro.
