How can I make docker-compose build an image from a remote git repository?
提问by billkw
Docker-compose allows you to utilize either pre?xisting docker images or build from source. For the build option, the official referencerequires
Docker-compose 允许您使用预先存在的 docker 镜像或从源代码构建。对于构建选项，官方参考要求
Either a path to a directory containing a Dockerfile, or a url to a git repository.
包含 Dockerfile 的目录的路径，或 git 存储库的 url。
I'd like to take advantage of the latter case, so that I don't have to create a git submodule in my project, or register a new repository on Docker Hub. Unfortunately, there are no examples for how to format the url, and every form I've tried is mistaken for a relative file path.
我想利用后一种情况，这样我就不必在我的项目中创建一个 git 子模块，或者在 Docker Hub 上注册一个新的存储库。不幸的是，没有关于如何格式化 url 的示例，而且我尝试过的每种形式都被误认为是相对文件路径。
e.g.
例如

letsencrypt:
build: https://github.com/letsencrypt/letsencrypt.git
...
Fails with the error:
因错误而失败：
ERROR: build path /{MY_CURRENT_PATH}/https:/github.com/letsencrypt/letsencrypt.git either does not exist or is not accessible.
错误：构建路径 /{MY_CURRENT_PATH}/https:/github.com/letsencrypt/letsencrypt.git 不存在或不可访问。
I didn't have any more luck with the other forms I've tried:
我尝试过的其他形式没有更多的运气：
- [email protected]:letsencrypt/letsencrypt.git
- git://github.com/letsencrypt/letsencrypt.git
- https://github.com/letsencrypt/letsencrypt
- [email protected]:letsencrypt/letsencrypt.git
- git://github.com/letsencrypt/letsencrypt.git
- https://github.com/letsencrypt/letsencrypt

Are you running version 1.5.2? It looks like this was actually recently added in https://github.com/docker/compose/pull/2430. Try upgrading.
您运行的是 1.5.2 版吗？看起来这实际上是最近在https://github.com/docker/compose/pull/2430 中添加的。尝试升级。
Example:
例子：
---
version: '2'
services:
redis:
image: "redis:3.2.3"
hostname: redis
redis-commander:
build: https://github.com/joeferner/redis-commander.git
command: --redis-host redis
links:
- "redis:redis"
ports:
- 8081
Tested with:
测试：
$ docker-compose -v
docker-compose version 1.11.2, build dfed245

The file tests/unit/config/config_test.pyshows:
该文件tests/unit/config/config_test.py显示：
def test_valid_url_in_build_path(self):
valid_urls = [
'git://github.com/docker/docker',
'[email protected]:docker/docker.git',
'[email protected]:atlassianlabs/atlassian-docker.git',
'https://github.com/docker/docker.git',
'http://github.com/docker/docker.git',
'github.com/docker/docker.git',
]
This is confirmed with compose/config/config.py#L79-L85:
这证实了compose/config/config.py#L79-L85：
DOCKER_VALID_URL_PREFIXES = (
'http://',
'https://',
'git://',
'github.com/',
'git@',
)
