git - 如何在 docker-compose 中访问私有(private) GitHub 存储库？

Question

这是我的 docker-compose.yml 文件:

version: '2.1'

services:

  users-db:
    container_name: users-db
    build: git@github.com:lukalopusina/flask-microservices-users.git#master:project/db
    volumes:
        - '~/.ssh/github:/root/.ssh/id_rsa'
    ports:
        - 5435:5432  # expose ports - HOST:CONTAINER
    environment:
      - POSTGRES_USER=postgres
      - POSTGRES_PASSWORD=postgres
    healthcheck:
      test: exit 0

这是 Dockerfile:

FROM postgres

# Disable checking for known_hosts (maybe not working)
RUN mkdir /root/.ssh && echo "StrictHostKeyChecking no " > /root/.ssh/config

# run create.sql on init
ADD create.sql /docker-entrypoint-initdb.d

当我运行 docker-compose up 时出现以下错误:

Building users-db
ERROR: Error trying to use git: exit status 128 (Cloning into '/var/lib/docker/tmp/docker-build-git576570106'...
Host key verification failed.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
)

问题可能与 ssh 权限有关，但我将我的 ssh key 作为挂载卷添加到容器中(或者我在那里犯了一些错误):

volumes:
    - '~/.ssh/github:/root/.ssh/id_rsa'

但是还是不行。如何解决这个问题？

这是 ~/.ssh 目录(我的主机)的权限:

drwx------   2 llopusina llopusina     4096 јун  7 14:22 .ssh

这些是 ~/.ssh(我的主机)中文件的权限:

-rw-------  1 llopusina llopusina 3243 јун  7 14:15 github
-rw-r--r--  1 llopusina llopusina  749 јун  7 14:15 github.pub
-rw-r--r--  1 llopusina llopusina 1326 јун  7 14:35 known_hosts

Answer 1

确保 .ssh 文件夹和您安装到容器的 key 具有正确的权限(文件夹为 700， key 文件为 600)并且所有者设置为 docker:docker

编辑: 它看起来像是 docker 守护进程和主机之间的键和上下文问题。我在 docker-compose 中发现了这个 Unresolved 问题: https://github.com/docker/compose/issues/2856

最终推荐的地方是:

FYI to anyone reporting: this is a known issue. <...> the solution is to do the git clone on the client side. We don't consider it high-priority, but PRs are always welcome.
