如何构造Docker项目以方便部署？ [英] How can I structure my docker projects for easy deployment?

问题描述

现在，我在同一个文件夹中将应用程序的多个组件与一个由docker-compose
链接在一起

Right now I have multiple components of my application in the same folder linked together with a docker-compose

这在开发中确实很好用，但是当我要进行生产时，这有点模糊。如果保持这种结构，我将无法仅使用dockerhub来托管我的图像，因为链接它们的docker-compose将会丢失。如果我使用git下拉docker-compose，那么dockerhub的意义是什么？为什么不克隆我的整个仓库并每次运行 docker-compose up ？

This works really well in development, but when I want to push to production it's kind of fuzzy. If I keep this structure I cannot use only dockerhub to host my images because the docker-compose which links them will be missing. If I use git to pull down my docker-compose, what would be the point of dockerhub? Why not just clone my whole repo and run docker-compose up each time?

我也可以存储每个组件分别在单独的github存储库中，将其推送到master时将其推送到dockerhub。然后，只需将它们从中心与dockercompose组合即可。这似乎也不太理想，因为必须克隆并推送到几个不同的存储库以进行影响系统的更改。

I could alternatively store each component separately in separate github repos, pushing them up to dockerhub when pushed to master. Then, simply combine them from the hub with a dockercompose. This seems less than ideal too, since one would have to clone and push to several different repos to make a change which effects the system.

您如何做到的？

推荐答案

查看新的（仍在试验中） docker-app （2018年6月）

Check out the new (still experimental) docker-app (June 2018)

它将允许您将docker-compose推送到DockerHub，以及通过dev和之间的设置差异（通过docker-compose）启动应用程序产品。

It will allow you to push your docker-compose to DockerHub, as well as launch your app (through docker-compose) with settings variations between dev and prod.

请参见示例：

您可以基于此撰写文件创建应用程序包：

You can create an Application Package based on this Compose file:

$ docker-app init --single-file hello
$ ls
docker-compose.yml
hello.dockerapp

新的网络w文件 hello.dockerapp 包含三个YAML文档：

The new new file hello.dockerapp contains three YAML documents:

• 元数据


• 撰写文件


• 您的应用程序设置

请参见 在集线器上共享应用程序

您可以使用docker-app push将任何应用程序推送到集线器：

You can push any application to the Hub using docker-app push:

$ docker-app push --namespace myHubUser --tag latest

此命令将在本地Docker守护程序上创建名为 myHubUser / hello.dockerapp：latest 的映像，并将其推送到集线器。

This command will create an image named myHubUser/hello.dockerapp:latest on your local Docker daemon, and push it to the Hub.
