Add Docker support

[arths31]

There it is, Docker support !

Thank you for this really nice retro server, brings back memories.
I used to work with Hebbo on multiple servers back in the days 😊

[arths31]

Detected an issue while entering the hotel related with crypto.
Checking what's wrong.

[arths31]

Fixed 👍🏻

[Quackster]

Thank you!

After a small review, there's a slight security risk, the RCON port is never meant to be exposed to the public.

[arths31]

Oh right, I think we can remove it from ports binding/ in havana-server.
Will try that today.

[arths31]

Working with port unbinded as expected.
I'll see if I can dockerize Minerva.

[arths31]

Done Quackster/Minerva#2

[Cuphead74832]

Cool to see someone did my idea. Would like to know if the container is usable or still in development. (I want to know if i can beta test It)

[arths31]

You can, I am already using it locally

[Cuphead74832]

You can, I am already using it locally

Nice

Had to delete the previous issue report due to personal data getting merged with the clipboard here is the full log of the issue when attemping to run docker-compose up, althrough this error the server finish its startup sequence but didnt test if registration worked i already assume it wont with this error but will try anyway later.

[arths31]

I see that it is trying to connect to host=127.0.0.1
Did you modify MYSQL_HOSTNAME in the variables ?

[EzpadaZ]

Hi @arths31 i tried following your docker tutorial at the end of your fork.

I'm having a little issue here, i downloaded the repo set all up, fixed some issues i had on my server related to java and after all compiled i get this

2024-07-30 10:09:21 exec /havana-server/bin/run.sh: no such file or directory 2024-07-30 10:09:22 exec /havana-server/bin/run.sh: no such file or directory 2024-07-30 10:09:25 exec /havana-server/bin/run.sh: no such file or directory 2024-07-30 10:09:28 exec /havana-server/bin/run.sh: no such file or directory 2024-07-30 10:09:35 exec /havana-server/bin/run.sh: no such file or directory 2024-07-30 10:09:48 exec /havana-server/bin/run.sh: no such file or directory

Any idea? i haven't moved any folder and just added a single file to the www folder (the .exe launcher).

My original thought is that this is caused by windows somehow (i tried ubuntu in WSL2 and thats the only place at first i got it to compile) but both show this and restart in an endless loop (as configured in the docker yaml).

[arths31]

I’ve tried on my Mac, I’ll check for issues on Linux as soon as possible

[arths31]

Just updated the branch to cleanup Docker files.
I've just tried on Ubuntu 24.04 and it is working.

Is it working if you just clone the repository and run docker-compose up ?

[Quackster]

I will test myself and report back when I have time. Thank you very much for this PR.

Some feedback:

• Modify the code to read from environment variables instead of relying on server.ini modification. (supporting both, prioritizing env above ini)
• Build the container images using jib instead. This will save on build time and total image size.
