Syncthing replaces proprietary sync and cloud services with something open, trustworthy and decentralized. Your data is your data alone and you deserve to choose where it is stored, if it is shared with some third party and how it's transmitted over the Internet.

Registry	`ghcr.io/daemonless/syncthing`
Daemonless	daemonless/syncthing
Source	syncthing/syncthing

Version Tags

Tag	Description	Best For
`latest`	Upstream Binary. Built from official release.	Alternative build.
`pkg`	FreeBSD Quarterly. Uses stable, tested packages.	Production stability.
`pkg-latest`	FreeBSD Latest. Rolling package updates.	Staying current.

Before deploying, ensure your host environment is ready. See the Quick Start Guide for host setup instructions, including the security model for host vs. container privileges.

Deployment

Podman AppJail Bastille

Compose CLI Ansible

services:
  syncthing:
    image: "ghcr.io/daemonless/syncthing:latest"
    container_name: syncthing
    volumes:
      - "/path/to/containers/syncthing:/config"
    ports:
      - "8384:8384"
      - "22000:22000"
      - "22000:22000"
      - "21027:21027"
    # always (not unless-stopped) so FreeBSD's podman rc.d auto-starts it at boot
    restart: always

Save as compose.yaml, then run podman-compose up -d.

podman run -d --name syncthing \
  -p 8384:8384 \
  -p 22000:22000 \
  -p 22000:22000 \
  -p 21027:21027 \
  -v /path/to/containers/syncthing:/config \
  ghcr.io/daemonless/syncthing:latest

Save as run.sh, then run sh run.sh.

- name: Deploy syncthing
  containers.podman.podman_container:
    name: syncthing
    image: "ghcr.io/daemonless/syncthing:latest"
    state: started
    restart_policy: always
    ports:
      - "8384:8384"
      - "22000:22000"
      - "22000:22000"
      - "21027:21027"
    volumes:
      - "/path/to/containers/syncthing:/config"

Save as syncthing-deploy.yaml, then run ansible-playbook syncthing-deploy.yaml.

Warning

Exposing ports in AppJail means that your service can be reached from remote hosts. If that is not your intention, do not expose the ports and communicate with the service using the jail's IPv4 address or hostname assigned by the virtual network.

Experimental

Bastille's OCI support is experimental. It requires buildah and shares the host network stack (inherit). Mount volumes with --volume HOST JAIL; without it, image-declared volumes are stored under ${bastille_volumesdir}/${jail}.

Compose CLI

services:
  syncthing:
    name: syncthing
    image: "ghcr.io/daemonless/syncthing:latest"
    network:
      - mode: host
    volumes:
      - "/path/to/containers/syncthing:/config"

Save as bastille-compose.yml, then run bastille up.

bastille create -O \
  --volume /path/to/containers/syncthing /config \
  syncthing ghcr.io/daemonless/syncthing:latest inherit

Access at: http://localhost:8384
