Syncthing Docker Image for Raspberry Pi on ARMv7

This repository containes a Dockerfile to create an image of Syncthing for Raspberry Pi on ARMv7. The image is based on the official Syncthing ARMv7 build and is automatically updated by my Raspberry Pi and pushed to Docker Hub (strobi/rpi-syncthing).

Build the image

If you want to use the prebuilt image from Docker Hub (strobi/rpi-syncthing) you can skip this step.

Build the image using docker build:

# BUILD_VERSION determines which version of syncthing is used for the image
# BUILD_VERSION must be the tag name of the release on GitHub without `v`, e.g. `1.6.0`
BUILD_VERSION=$(curl -s https://api.github.com/repos/syncthing/syncthing/releases/latest | jq -r .tag_name )
BUILD_VERSION=${BUILD_VERSION:1}

# Build
docker build --no-cache --build-arg BUILD_DATE=$(date -u +'%Y-%m-%dT%H:%M:%SZ') --build-arg BUILD_VERSION=${LATEST_RELEASE} .

Start the container

Make sure that the directories ~/syncthing/config and ~/syncthing/data exist on the host and that the default user pi (or more precisely the user with uid 1000 and gid 1000) has read and write permissions for the directories.

Start the container using docker run:

docker run -d -p 8384:8384 -p 22000:22000 -p 21027:21027 -v ~/syncthing/config:/syncthing/config -v ~/syncthing/data:/syncthing/data strobi/rpi-syncthing:latest

If you want to use docker-compose to manage the container, create a file named docker-compose.yml with the following content:

version: '2'

networks:
  syncthing:
    external: false

services:
  syncthing:
    image: strobi/rpi-syncthing:latest

      - "22000:22000"
