如何让nektos/act创建已挂载指定卷的Docker容器？

我已经搭建了本地Docker环境，正在优化setup-miniconda的运行效率：

• 已构建自定义Docker镜像并推送到本地仓库
• 改用conda-lock，无需再解析environment.yaml
• 最后一步需要让act创建容器时自动挂载指定卷，实现Conda包下载目录的共享，效果等同于执行：

docker run -it -v /home/vagrant/miniconda/pkgs/:/root/miniconda3/pkgs localhost:5000/my-act /bin/bash

我尝试修改了docker_run.go文件：

func (cr *containerReference) Create(capAdd []string, capDrop []string) common.Executor {
    cr.input.Mounts["/root/miniconda3/pkgs"] = "/home/vagrant/miniconda/pkgs"
    return common.
        NewInfoExecutor("%sdocker create image=%s platform=%s entrypoint=%+q cmd=%+q", logPrefix, cr.input.Image, cr.input.Platform, cr.input.Entrypoint, cr.input.Cmd).
        Then(
            common.NewPipelineExecutor(
                cr.connect(),
                cr.find(),
                cr.create(capAdd, capDrop),
            ).IfNot(common.Dryrun),
        )
}

.actrc配置：

-P ubuntu-latest=localhost:5000/my-act

本地仓库创建脚本：

actimg="localhost:5000/my-act"
docker run -d -p 5000:5000 --restart=always --name registry registry:2
docker build --no-cache -t act-custom:v1 .
docker tag act-custom:v1 $actimg
docker push $actimg
