Add v2ray-plugin Docker image example

[realies]

If this is to go into the Docker image release workflow, it needs to pull the correct architecture version of the plugin.

@zonyitoo, should the v2ray-plugin be added in the current Docker image or as a separate tag?

[zonyitoo]

It shouldn't be included in this Project. If v2ray-plugin could be packaged in the image, why wouldn't the others?

[realies]

@zonyitoo, primarily because the v2ray-plugin is maintained by the shadowsocks organisation. It would be useful to have an official image that includes it, would the v2ray-plugin repository be more suitable?

[zonyitoo]

I think you could modify this Dockerfile to Dockerfile.plugin which could include all official maintained plugins.

But, is it possible to make a v2ray-plugin only image and then run multiple images in a k8s group? In that case you won't need to package all plugins into one image.

[realies]

@zonyitoo, Is there a list of all plugins maintained by shadowsocks somewhere? https://shadowsocks.org/en/wiki/Plugin.html points me to kcptun and v2ray-plugin.

Not sure I understand the question about the k8s group - assume you mean creating a plugin image and mounting its binary into a barebones shadowsocks-rust container? Not aware if that's possible, but if it is, it may require Kubernetes.

[zonyitoo]

You could just create a Dockerfile.plugin file for creating an image containing sslocal or ssserver with plugins. And then make a document for guiding how to add new plugins into this image.

All the following requests about adding plugins could make a PR to add it into this Dockerfile.plugin.

This solution have some obvious flaws:

1. The image might be large because it will contain many plugins that you don't need.
2. When you need a new plugin, making a new PR, merge, waiting for the next release may be too long for users that need to use it immediately.

Kubernetes should be a possible solution.

Based on your description (about mounting binaries), there should be a solution that you could just download the v2ray-plugin releases on your host machine and then mount them into the container's /usr/bin/v2ray-* paths. Flexible, and easy to manage. One possible flaw is that if the plugin requires some other runtime, such as Python, then it will become an issue.
