TaskChampion Sync-Server

TaskChampion is the task database Taskwarrior uses to store and sync tasks. This repository implements a sync server against which Taskwarrior and other applications embedding TaskChampion can sync.

Status

This repository was spun off from Taskwarrior itself after the 3.0.0 release. It is still under development and currently best described as a reference implementation of the Taskchampion sync protocol.

It is comprised of three crates:

• taskchampion-sync-server-core implements the core of the protocol
• taskchmpaion-sync-server-sqlite implements an SQLite backend for the core
• taskchampion-sync-server implements a simple HTTP server for the protocol

Running the Server

The server is configured with command-line options. See taskchampion-sync-server --help for full details.

The --data-dir option specifies where the server should store its data, and --port gives the port on which the HTTP server runs. The server does not implement TLS; for public deployments, the recommendation is to use a reverse proxy such as Nginx, haproxy, or Apache httpd.

By default, the server allows all client IDs. To limit the accepted client IDs, such as when running a personal server, use --allow-client-id <client-id>.

The server only logs errors by default. To add additional logging output, set environment variable RUST_LOG to info to get a log message for every request, or to debug to get more verbose debugging output.

Installation

As container

To build the container execute the following commands.

source .env
docker build \
  --build-arg RUST_VERSION=${RUST_VERSION} \
  --build-arg ALPINE_VERSION=${ALPINE_VERSION} \
  -t taskchampion-sync-server .

Now to run it, simply exec.

docker run -t -d \
  --name=taskchampion \
  -p 8080:8080 \
  taskchampion-sync-server

This start TaskChampion Sync-Server and publish the port to host. Please note that this is a basic run, all data will be destroyed after stop and delete container.

Persist data using a container volume

TaskChampion Sync-Server container image uses a volume /var/lib/taskchampion-sync-server to store database. You can exec the following to mount it in your host as persistent storage.

docker run -t -d \
  --name=taskchampion \
  -p 8080:8080 \
  -v /my/taskchampion-sync-server:/var/lib/taskchampion-sync-server \
  taskchampion-sync-server

Take note that you must create before the directory /my/taskchampion-sync-server and set ownership to UID/GID 100.

mkdir -p /my/taskchampion-sync-server
chown -R 100:100 /my/taskchampion-sync-server
