[varbhat]

Yes. This is the reason and major obstacle for this project. I will take a look into it

Hi,
I made a PR to optimize docker image size that seem to fix this issue:

Hi @aicynide,

If you want I made a fork here : https://github.com/nlevee/exatorrent compilation work as expected

[mckaygerhard]

@nlevee @aicynide there is only one issue left . the user alisaing is not the xpected case.. this fail in my system: cos in fact that useer 1000 doe snot exits in my docker image

main...nlevee:exatorrent:feat/optimize-dockerfile#diff-dd2c0eb6ea5cfc6c4bd4eac30934e2d5746747af48fef6da689e85b752f39557R34

[nlevee]

Yes, I can fix it, but I'll hope this PR to pass before.

@varbhat can you merge ? Else I can continue on my fork.

[varbhat]

@nlevee,

I am glad that you are working on improving exatorrent.

But, two things.

1. Use alpine as final image instead of scratch image. You get TLS certs managed in alpine image. In scratch, you need to copy TLS certs to the image which is not very good way compared to directly basing upon alpine images. Maybe we can look into using linuxcontainers.io images too but we can do this later.

2. Have you tried updating the deps in go.mod and compiling then? I am facing issues compiling after updating deps in go.mod probably from anacrolix/torrent packages and deps (esp. sqlite). See it if possible

[nlevee]

1. Ok, I change to alpine and add ca-certificates.
2. No I don't try to update go.mod, the latest version of anacrolix/torrent drop compatibility with go 1.20. I have to update all deps. I'll try in another PR If it's ok for you and to keep this PR clean

@mckaygerhard I fix the image startup if you don't load a volume and do not change "-dir" param

[nlevee]

I fixed compilation on golang 1.21 with all libraries updated, you can check the PR #404

[varbhat]

@nlevee ,

Thank you very much. Can you make da81de4 as seperate PR?

[mckaygerhard]

@nlevee .. i talked with @varbhat so you can work in this now, and @varbhat he made a PR in #404

[varbhat]

@nlevee ,

Once upon a time, we used to provide statically linked binaries for all three platforms (see https://github.com/varbhat/exatorrent/blob/15d4e8c73d5572dedd2c504ff33d2008d1caf5ba/.github/workflows/build.yml ). But, unfortunately i couldn't maintain the toolchain i used to build exatorrent for all three platforms, and that's why i only kept docker builds.

Can you please look into it if you have time? Only linux (amd64, arm64) is desirable right now. if you have time, you can also add build definitions for linux i386, arm32. use alpine image for building as musl makes static linking a breeze.

Thank you very much. I have also invited you as collaborator.

@nlevee you should still solve this issue

bvy example you requested specific permissions not only cited by me.. also cited here: awesome-selfhosted/awesome-selfhosted-data#143 (review)

I'll take this one too yes.

Btw there's already an issue on this #377

This one was partly fixed in my previous PR. You can check if you want 😉

I'll make another PR to permit mounting volume

You can know build locally with:

make web && make app

Or with docker:

make docker
