如何将参数传递给在CLI(命令行界面)中运行的docker? [英] How do I pass arguments to docker run in a CLI (Command Line Interface)?

问题描述

我需要我的图片以以下命令开头:

I need my image to start with this command:

docker run -it --rm --security-opt seccomp=./chrome.json <image_id>

我正在将其部署到Google Compute Engine: https://cloud.google.com/compute/docs/containers/deploying-containers

I'm deploying it to Google Compute Engine: https://cloud.google.com/compute/docs/containers/deploying-containers

据我了解，我无法在此处指定参数，因此Google Cloud仅使用 docker run 命令启动它.

As far as I understand, I can't specify arguments there, so Google Cloud starts it with just docker run command.

如何传递这些参数?也许我可以以某种方式在Dockerfile中指定这些args?

How do I pass these arguments? Maybe I can specify those args in Dockerfile somehow?

推荐答案

当您使用该功能直接在Compute Engine上部署容器时，仅限于

When you use the feature to deploy container directly on Compute Engine, you are limited to the definition of

• 入口点
• Args在入口点通过
• 环境变量

仅此而已，您无法添加其他/自定义参数.

That's all, you can't add additional/custom params.

一种解决方案是使用

One solution is, instead of using the built in feature, to use the container-optimized OS (COS) on your Compute Engine and to create a startup script to download and run the container with the docker args that you want

METADATA=http://metadata.google.internal/computeMetadata/v1
SVC_ACCT=$METADATA/instance/service-accounts/default
ACCESS_TOKEN=$(curl -H 'Metadata-Flavor: Google' $SVC_ACCT/token | cut -d'"' -f 4)
docker login -u oauth2accesstoken -p $ACCESS_TOKEN https://gcr.io
docker run … gcr.io/your-project/your-image

在最后一行，您可以在启动脚本中自定义运行参数.

On the latest line, you can customize the run param in your startup script.

因此，现在，对于更新，您必须更新启动脚本并重置VM(或使用COS和新的启动脚本创建新的Compute Engine；并删除前一个).

So now, for the update, you have to update the startup script and to reset your VM (or to create a new Compute Engine with COS and the new startup script; and to delete the previous one).

内置功能的便利性与自定义功能之间需要权衡取舍.

It's matter of tradeoff between the convenience of a built in feature and the customization capacity.
