Feature request: Docker support about koishi

[NN708]

Docker support for Koishi is now available on Docker Hub: https://hub.docker.com/r/koishijs/koishi (version 1.12.0). docker-compose.yml can be used to deploy CoolQ, CQHTTP, MySQL and Koishi very quickly.

More Things To-Do

• Write instructions for Docker on Koishi website
• Port Docker support to Koishi v2
• Install plug-ins automatically
• Use environment variables to initialize (type, port, server, selfId, MySQL configuration)

Discussion

The starting script start.js is basically the same as koishi init, but use environment variables. Is it possible to add something like koishi init -d, letting it read environment variables to initialize configuration file?

Due to the sunset of CoolQ and CQHTTP, we are now pending Mrs4s/go-cqhttp#7.

I don't think building a Docker image for Koishi itself is a good idea. Docker images should be built by upstream developers.
Anyway, is this Docker image a base image for other Docker images of apps depend on Koishi be built? I think building an official image like this may also be a good idea. eg.

FROM koishi
WORKDIR /usr/src/app
COPY ./package*.json ./
RUN npm ci
COPY . ./
RUN npm run build
CMD npm start

Another choice is, to build an ONBUILD image for quick deployment.

@purerosefallen Thank you for your suggestions! However, this official Docker image is mainly for users who want to quickly deploy only Koishi and public plugins with one-click. For upstream developers, I think that building your own Docker image based on Node is simpler, and this official image for Koishi could be a reference for you.

Due to the down of CoolQ and CQHttp, the example docker-compose.yml file's CQHttp backend could be replaced by either of these below.
https://hub.docker.com/r/scjtqs/mirai-cqhttp
https://hub.docker.com/r/nanahira/go-cqhttp
The 1st one is a CQHttp run on Mirai, while the 2nd one is my own fork of go-cqhttp . You may consider either.

@purerosefallen Thank you for your Docker image! I have updated docker-compose.yml in branch docker.

Using Docker page has been released on Koishi website. Closing this issue now.
