docker support

[Tech0ne]

Added Dockerfile.server and Dockerfile.client, respectivelly running iodined and iodine on alpine 3.22.0
Build:

• sudo docker build -t iodined -f Dockerfile.server .
• sudo docker build -t iodine -f Dockerfile.client .

Usage:

• sudo docker run -it --rm --device /dev/net/tun --cap-add=NET_ADMIN iodined -f 10.0.0.1 test.com
• sudo docker run -it --rm --device /dev/net/tun --cap-add=NET_ADMIN iodine -f -r 192.168.0.1 test.com

I tried with podman build and it fails:

STEP 5/8: RUN git clone https://github.com/yarrick/iodine /app/
Cloning into '/app'...
--> 5062214cb419
STEP 6/8: RUN make
make[1]: Entering directory '/app/src'
OS is LINUX, arch is x86_64

      |          ^~~~~~~~~
compilation terminated.

Also I am not sure why this needs to be in this repo and then clone the code again?

[JuniorJPDJ]

It doesn't need to clone code again, it shouldn't - it should copy it from context.

[yarrick]

The RUN git clone https://github.com/yarrick/iodine /app/ seems to happen even if it is run in a directory that is already a clone of it.

[JuniorJPDJ]

Yes, but it shouldn't. PR author did wrong thing.

Hello,

Sorry for wasting your time

Originally, I made the Dockerfiles to be self-contained ones, explaining the git clone.

Will update that soon.

[Tech0ne]

From my testing, it now works.

It was tested using Docker.

Please provide errors if any.

(also removed the useless git clone :} )

Hope you'll enjoy !

[yarrick]

Can you add multi-stage build to avoid keeping the source code and build tools in the final images?

Also remove all non-essential things from the files (old code, ascii art) and move it into a docker directory?

It seems there is no standardized way of sharing the build step and using it for two different outputs

[Tech0ne]

Copy that, will do ASAP.

Is it ok to keep the ascii art ? Kind of like it tbh :}

And I'll look into build steps, to try and make them as versatile as possible.

[Tech0ne]

Multi stage build added.

Removed useless comments (except ascii art :} )

Moved both client and server Dockerfile to a docker/ directory.

Added build command as comment.

Runner stage also uses ubuntu 24.04.

Hi, nice work over here!

I did give a try to the code of this PR, and it was missing a package in the final stage: net-tools because ifconfig was needed both by iodine and iodined.

If you git apply this patch it should work. (I also removed the ascii arts)
