Docker从git存储库构建上下文，其中Dockerfile位于文件夹中 [英] Docker Compose build context from git repository with Dockerfile inside folder

问题描述

我想使用git存储库在docker compose项目中构建新映像，因为我需要更改一些ARG变量。

I would like to build a new image in my docker compose project using a git repository as I need to change some ARG vars.

我担心的是Dockerfile

My concern is that the Dockerfile is inside a folder of the git repository.

如何使用git仓库将文件夹指定为构建上下文？

How can be specified a folder as build context using a git repository?

存储库： https://github.com/wodby/drupal -php / blob / master / 7 / Dockerfile

version: "2"
services:
  php:
    build:
      context: https://github.com/wodby/drupal-php.git
      dockerfile: 7/Dockerfile
      args:
         - BASE_IMAGE_TAG=7.1
         - WODBY_USER_ID=117
         - WODBY_GROUP_ID=111
      volumes:
          - ./:/var/www/html

我尝试了dockerfile属性： FOLDER / + Dockerfile

I've tried the dockerfile property: "FOLDER/" + Dockerfile

但是仓库使用相对拍拍hs，但找不到依赖项：

But the repository uses relative paths, and it doesn't find dependencies:

 ---> 6cc2006e9102
Step 7/9 : COPY templates /etc/gotpl/
ERROR: Service 'phpe' failed to build: COPY failed: stat /var/lib/docker/tmp/docker-builder740707850/templates: no such file or directory

推荐答案

应该是这样的： myrepo.git＃：myfolder

It should be this way: myrepo.git#:myfolder

version: "2"
services:
  php:
    build:
      context: https://github.com/wodby/drupal-php.git#:7
      args:
         - BASE_IMAGE_TAG=7.1
         - WODBY_USER_ID=117
         - WODBY_GROUP_ID=111
      volumes:
          - ./:/var/www/html
