[DOCKER] Launch code-server on alpine-linux

Launch code-server on Alpine-Linux

It is necessary to build a Python development environment and conduct a survey. I started it with the following Dockerfile and found that it can be used implicitly. I used python official 3.7-alpine as the base image, but I think it can be started with normal alpine-linux.

FROM python:3.7-alpine

RUN apk --no-cache --update add alpine-sdk bash libstdc++ libc6-compat npm libx11-dev libxkbfile-dev libsecret-dev && \
    npm config set unsafe-perm true && \
    npm install -g code-server

ENTRYPOINT ["code-server", "--auth", "none", "--bind-addr", "0.0.0.0:8080"]
CMD [""]

Notes

• Port number is 8080, so port mapping is required when docker starts
• If you do not create the key information, there seems to be a problem with accessing the clipboard etc. from the browser etc.? I get a warning if it is insecure.
• Not slimmed down. Currently, it is displayed as 944MB on docker images.
• Since authentication is also removed, it is at your own risk to start up in places such as the Internet that are accessed from the outside.
• Other than that, I haven't used it yet, so I don't know what other problems there are.
