在主机之间移动docker-compose容器集 [英] Moving docker-compose containersets around between hosts

问题描述

我想获取由3个docker映像组成并由docker-compose管理的应用程序堆栈，并将其全部从开发机器移至生产机器。我知道有几种方法可以直接使用docker：

I would like to take my application stack, consisting of 3 docker images and managed by docker-compose, and move it in its entirety from my development machine onto a production machine. I know of a few ways to do this with straight up docker:

• 将图像推送到注册表并将其从生产环境撤回


• 从开发中保存docker，然后将docker加载到生产中


• 在生产中重建映像（宁愿保持对生产的依赖性，所以不是一个好的选择。）

我目前倾向于先保存docker然后再加载docker，但我想知道是否有办法做到这一点docker-compose管理的整套容器？

I'm currently leaning towards doing docker save and then docker load, but am wondering if there's a way to do this with the whole set of containers that docker-compose manages?

预先感谢

推荐答案

撰写中没有功能保存构建在Compose文件中的图像，这是docker客户端的工作（如您使用 docker save 和 docker load ）。幸运的是，使用bash很简单：

There is no functionality in Compose to save the images built in a Compose file, it's the job of the docker client (as you stated with docker save and docker load). Fortunately it's straightforward with bash:

images=(web cache db)
for image in images
do
    docker save ${image} > ${image}.tar
    scp ${image}.tar $yourhost:
    ssh $yourhost docker load ${image}.tar
done

远程注册表选项也许是一种更生产级的方法。左右移动一堆图像可能会非常慢，但是YMMV。

The remote registry option is perhaps a more "production grade" approach. Moving a bunch of images around is likely to be pretty slow, but YMMV.
