[PairDrop](https://github.com/schlagmichdoch/PairDrop) is a sublime alternative to AirDrop that works on all platforms. Send images, documents or text via peer to peer connection to devices in the same local network/Wi-Fi or to paired devices.
## Supported Architectures
We utilise the docker manifest for multi-platform awareness. More information is available from docker [here](https://github.com/docker/distribution/blob/master/docs/spec/manifest-v2-2.md#manifest-list) and our announcement [here](https://blog.linuxserver.io/2019/02/21/the-lsio-pipeline-project/).
Simply pulling `lscr.io/linuxserver/pairdrop:latest` should retrieve the correct image for your arch, but you can also pull specific arch images via tags.
The architectures supported by this image are:
| Architecture | Available | Tag |
| :----: | :----: | ---- |
| x86-64 | ✅ | amd64-\<version tag\> |
| arm64 | ✅ | arm64v8-\<version tag\> |
| armhf | ❌ | |
## Application Setup
Web UI is accessible at http://SERVERIP:PORT. It is strongly recommended to run PairDrop via a reverse proxy, served over HTTPS, if you are making it publicly available. In this configuration you must ensure that the `X-Forwarded-For` header is being set correctly, otherwise all clients will be mutually visible.
Most proxies will set this header automatically but may require additional configuration if you are using something like Cloudflare Proxy.
To specify custom STUN/TURN servers for PairDrop clients to use, create a JSON config file in a mounted path and use the RTC_CONFIG environment variable to point to it.
You can use https://raw.githubusercontent.com/schlagmichdoch/PairDrop/master/rtc_config_example.json as a starting point.
Enabling WS_FALLBACK provides a fallback if the peer to peer WebRTC connection is not available to the client.
This is especially useful if you connect to your instance via a VPN as most VPN services block WebRTC completely in order to hide your real IP address.
*Warning*: All traffic sent between devices using this fallback is routed through the server and therefor not peer to peer! Traffic routed via this fallback is readable by the server and uses the server's bandwidth.
## Usage
To help you get started creating a container from this image you can either use docker-compose or the docker cli.
### docker-compose (recommended, [click here for more info](https://docs.linuxserver.io/general/docker-compose))
Docker images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate `<external>:<internal>` respectively. For example, `-p 8080:80` would expose port `80` from inside the container to be accessible from the host's IP on port `8080` outside the container.
### Ports (`-p`)
| Parameter | Function |
| :----: | --- |
| `3000` | http gui |
### Environment Variables (`-e`)
| Env | Function |
| :----: | --- |
| `PUID=1000` | for UserID - see below for explanation |
| `PGID=1000` | for GroupID - see below for explanation |
| `TZ=Etc/UTC` | specify a timezone to use, see this [list](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones#List). |
| `RATE_LIMIT=false` | Set to `true` to limit clients to 100 requests per 5 min |
| `WS_FALLBACK=false` | Set to `true` to enable websocket fallback if the peer to peer WebRTC connection is not available to the client (see App Setup notes). |
| `DEBUG_MODE=false` | Set to `true` to debug the http server configuration by logging clients IP addresses used by PairDrop to STDOUT. [See here for more info](https://github.com/schlagmichdoch/PairDrop/blob/master/docs/host-your-own.md#debug-mode). Do not use in production! |
## Environment variables from files (Docker secrets)
You can set any environment variable from a file by using a special prepend `FILE__`.
As an example:
```bash
-e FILE__PASSWORD=/run/secrets/mysecretpassword
```
Will set the environment variable `PASSWORD` based on the contents of the `/run/secrets/mysecretpassword` file.
## Umask for running applications
For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional `-e UMASK=022` setting.
Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up [here](https://en.wikipedia.org/wiki/Umask) before asking for support.
## User / Group Identifiers
When using volumes (`-v` flags), permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user `PUID` and group `PGID`.
Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.
In this instance `PUID=1000` and `PGID=1000`, to find yours use `id user` as below:
[](https://mods.linuxserver.io/?mod=pairdrop "view available mods for this container.") [](https://mods.linuxserver.io/?mod=universal "view available universal mods.")
We publish various [Docker Mods](https://github.com/linuxserver/docker-mods) to enable additional functionality within the containers. The list of Mods available for this image (if any) as well as universal mods that can be applied to any one of our images can be accessed via the dynamic badges above.
## Support Info
* Shell access whilst the container is running:
*`docker exec -it pairdrop /bin/bash`
* To monitor the logs of the container in realtime:
*`docker logs -f pairdrop`
* Container version number
*`docker inspect -f '{{ index .Config.Labels "build_version" }}' pairdrop`
* Image version number
*`docker inspect -f '{{ index .Config.Labels "build_version" }}' lscr.io/linuxserver/pairdrop:latest`
