Optimized Dockerfile

[CreativeCactus]

Based on this PR I have prepared a Dockerfile.

• Based on alpine (light weight)
• Build app during docker build (not when container starts, allows pulling built files from image directly)
• Optimized instructions (copy package.json first, code changes do not require re-running install steps)
• Reproducible (npm ci respects exact lock file versions)
• ENTRYPOINT & CMD array syntax (allows overriding the CMD easily when running)
• npm scripts (to demonstrate basic usage and set conventional image name)
• Support for hot-reload development inside volumes (untested)

I've just tested, and everything works well with 2 notes:

• I used webpack serve --mode production --env production to serve, but I get dev warnings (about package size) when I load the page. Otherwise it works well. How is MiniPaint usually deployed? I can make the CMD match the normal deployment. I'm guessing it's just a static serve of dist?
• I got "Invalid host header" when using domain names other than localhost, can/should this be set/disabled by environment variable for docker?

Let me know if you have any questions or would like to use docker for deployments! It will make your life easier! :)

I added your PR into wiki, so everybody can find it easily. There are multiple versions, so I don't want to move it to main code yet.

It looks like the language tag is missing for some of those code blocks.

I think the ghost implementation can be removed, or at least placed last, since it is objectively worse than the two alpine versions.

Do you see these implementations getting merged eventually, or will they remain as wikis?

? Can you give more details?

it is hard to rate these versions, but I will order by date descending, which should work well for most users. Ghost version is last now.

I would like to keep it as is for some time and see how it works. If multiple users will agree on some changes, we can do it in future.

Feel free to add more comments or reopen it in future, but for now I am closing it.

p.s. language tags are added.
