timew-sync-server

Timewarrior Sync Server

This repository contains the Server of the Timewarrior Sync project.

Setup

Building from source

First you need to build the server:

go build -o timew-server

If you haven't already, create a folder named authorized_keys in the same folder as your executable:

mkdir authorized_keys

Now you can start using your server:

./timew-server start

Using Nix

timew-sync-server is included in Nixpkgs. To install timew-sync-server into your current environment, use:

nix-env -i timew-sync-server

Then, follow the instructions above (create a directory for the keys and start the server).

Using docker

You can build a docker image using the provided Dockerfile:

# Build a docker image tagged timew-server
docker build -t timew-server .

To start the server, use:

# Running from the docker image tagged timew-server
docker run -p 8080:8080 timew-server

# Start an existing docker container
docker start <container-id>

Subcommands can be used via docker exec:

docker exec -it <container-id> server <subcommand>

Usage

Starting the server

Start the server using the start subcommand:

./timew-server start

The start subcommand supports the following (optional) flags:

• --config-file: (reserved, not used yet) Specifies the path to the configuration file
• --port: Specifies the port. Default: 8080
• --keys-location: Specifies the folder holding the authorized keys. Default: authorized_keys
• --no-auth: Deactivates client authentication. Only for testing purposes.
• --sqlite-db: Path to the sqlite database. Default: db.sqlite

Adding users

New users can be registered using the add-user subcommand:

./timew-server add-user

If no additional flags are specified, this command will return the new user id.

The add-user subcommand supports the following flags:

• --path: Specifies the path to a public key and associates it with the user.
• --keys-loaction: Specifies the folder holding the authorized keys. Default: authorized_keys

Note: If you are running our provided Docker image, see the note under Adding keys to users.

Adding keys to users

New keys can be added using the add-key subcommand:

./timew-server add-key --path public-key.pem --id <user-id>

The add-key subcommand supports the following flags:

• --path (required): Specifies the path to a public key and associates it with the user.
• --id (required): Specifies the user id.
• --keys-location: Specifies the folder holding the authorized keys. Default: authorized_keys

Note: If you are running the server inside a docker container, you have to copy the key into the container first:

# Copy the key into /public-key.pem
docker cp public-key.pem <container-id>:/public-key.pem

# Add the key
docker exec -it <container-id> server add-key --path /public-key.pem --id <user-id>

Development

The code has to be formatted using go fmt before commits. To enforce this, we provide a pre-commit-hook. It can be setup by copying it into to your .git/hooks/pre-commit:

cp git/hooks/pre-commit .git/hooks/pre-commit
