copyparty/scripts/docker/README.md

copyparty is availabe in these repos:
* https://hub.docker.com/u/copyparty
* https://github.com/9001?tab=packages&repo_name=copyparty


# getting started

run this command to grab the latest copyparty image and start it:
```bash
docker run --rm -it -u 1000 -p 3923:3923 -v /mnt/nas:/w -v $PWD/cfgdir:/cfg copyparty/ac
```

* `/w` is the path inside the container that gets shared by default, so mount one or more folders to share below there
* `/cfg` is an optional folder with zero or more config files (*.conf) to load
* `copyparty/ac` is the recommended [image edition](#editions)
* you can download the image from github instead by replacing `copyparty/ac` with `ghcr.io/9001/copyparty-ac`
* if you are using rootless podman, remove `-u 1000`
* if you have selinux, append `:z` to all `-v` args (for example `-v /mnt/nas:/w:z`)

this example is also available as a podman-compatible [docker-compose yaml](https://github.com/9001/copyparty/blob/hovudstraum/docs/examples/docker/basic-docker-compose); example usage: `docker-compose up` (you may need to `systemctl enable --now podman.socket` or similar)

i'm not very familiar with containers, so let me know if this section could be better 🙏


## configuration

> this section basically explains how the [docker-compose yaml](https://github.com/9001/copyparty/blob/hovudstraum/docs/examples/docker/basic-docker-compose) works, so you may look there instead

the container has the same default config as the sfx and the pypi module, meaning it will listen on port 3923 and share the "current folder" (`/w` inside the container) as read-write for anyone

the recommended way to configure copyparty inside a container is to mount a folder which has one or more [config files](https://github.com/9001/copyparty/blob/hovudstraum/docs/example.conf) inside; `-v /your/config/folder:/cfg`

* but you can also provide arguments to the docker command if you prefer that
* config files must be named `something.conf` to get picked up


## editions

with image size after installation and when gzipped

* [`min`](https://hub.docker.com/r/copyparty/min) (57 MiB, 20 gz) is just copyparty itself
* [`im`](https://hub.docker.com/r/copyparty/im) (70 MiB, 25 gz) can thumbnail images with pillow, parse media files with mutagen
* [`ac` (163 MiB, 56 gz)](https://hub.docker.com/r/copyparty/ac) is `im` plus ffmpeg for video/audio thumbs + audio transcoding + better tags
* [`iv`](https://hub.docker.com/r/copyparty/iv) (211 MiB, 73 gz) is `ac` plus vips for faster heif / avic / jxl thumbnails
* [`dj`](https://hub.docker.com/r/copyparty/dj) (309 MiB, 104 gz) is `iv` plus beatroot/keyfinder to detect musical keys and bpm

[`ac` is recommended](https://hub.docker.com/r/copyparty/ac) since the additional features available in `iv` and `dj` are rarely useful

most editions support `x86`, `x86_64`, `armhf`, `aarch64`, `ppc64le`, `s390x`
* `dj` doesn't run on `ppc64le`, `s390x`, `armhf`
* `iv` doesn't run on `ppc64le`, `s390x`


## detecting bpm and musical key

the `dj` edition comes with `keyfinder` and `beatroot` which can be used to detect music bpm and musical keys

enable them globally in a config file:
```yaml
[global]
e2dsa, e2ts  # enable filesystem indexing and multimedia indexing
mtp: .bpm=f,t30,/mtag/audio-bpm.py  # should take ~10sec
mtp: key=f,t190,/mtag/audio-key.py  # should take ~50sec
```

or enable them for just one volume,
```yaml
[/music]  # share name / URL
  music   # filesystem path inside the docker volume `/w`
  flags:
    e2dsa, e2ts
    mtp: .bpm=f,t30,/mtag/audio-bpm.py
    mtp: key=f,t190,/mtag/audio-key.py
```

or using commandline arguments,
```
-e2dsa -e2ts -mtp .bpm=f,t30,/mtag/audio-bpm.py -mtp key=f,t190,/mtag/audio-key.py
```


# build the images yourself

basically `./make.sh hclean pull img push` but see [devnotes.md](./devnotes.md)
