docker - 如何在CircleCI配置中为Docker容器指定卷？

Question

我没有设法找出如何在config.yml中安装docker镜像卷以与CircleCI集成。

官方文件为
container usage，入口点，命令等，但与卷安装无关。

场景是，我的项目的构建需要两个docker容器，一个是主容器，另一个是用于服务foo的容器。要使用服务foo，我需要将前面步骤中生成的一些 Artifact 暴露给foo容器，然后执行一些后续步骤。

有人知道我是否可以这样做吗？

如从CircleCI documentation截取的:

Mounting Folders
It’s not possible to mount a folder from your job space into a container in Remote Docker (and vice versa). But you can use docker cp command to transfer files between these two environments. For example, you want to start a container in Remote Docker and you want to use a config file from your source code for that:

- run: |
    # creating dummy container which will hold a volume with config
    docker create -v /cfg --name configs alpine:3.4 /bin/true
    # copying config file into this volume
    docker cp path/in/your/source/code/app_config.yml configs:/cfg
    # starting application container using this volume
    docker run --volumes-from configs app-image:1.2.3
In the same way, if your application produces some artifacts that need to be stored, you can copy them from Remote Docker:

- run: |
    # starting container with our application
    # make sure you're not using `--rm` option otherwise container will be killed after finish
    docker run --name app app-image:1.2.3

- run: |
    # once application container finishes we can copy artifacts directly from it
    docker cp app:/output /path/in/your/job/space
