Provide a docker-compose.yml that will run a server, with TLS (#68)
This is intended to support the user journey of someone with a VPS who wants to set up the sync server, but does not have the knowledge and skills to set up a reverse proxy and TLS certificate themselves.

|

## Running the Server
|
||||
|
||||
The server is a simple binary that serves HTTP requests on a TCP port. The
|
||||
server does not implement TLS; for public deployments, the recommendation is to
|
||||
use a reverse proxy such as Nginx, haproxy, or Apache httpd.
|
||||
|
||||
### Using Docker-Compose
|
||||
|
||||
The [`docker-compose.yml`](./docker-compose.yml) file in this repository is
|
||||
sufficient to run taskchampion-sync-server, including setting up TLS
|
||||
certificates using Lets Encrypt, thanks to [Caddy](https://caddyserver.com/).
|
||||
|
||||
You will need a server with ports 80 and 443 open to the Internet and with a
|
||||
fixed, publicly-resolvable hostname. These ports must be available both to your
|
||||
Taskwarrior clients and to the Lets Encrypt servers.
|
||||
|
||||
On that server, clone this repository (or just download `docker-compose.yml` to
|
||||
the current directory -- the rest of the contents of this repository are not
|
||||
required) and run
|
||||
|
||||
```sh
|
||||
TASKCHAMPION_SYNC_SERVER_HOSTNAME=taskwarrior.example.com docker compose up
|
||||
```
|
||||
|
||||
It can take a few minutes to obtain the certificate; the caddy container will
|
||||
log a msg "certificate obtained successfully" when this is complete, or error
|
||||
messages if the process fails. Once this process is complete, configure your
|
||||
`.taskrc`'s to point to the server:
|
||||
|
||||
```
|
||||
sync.server.url=https://taskwarrior.example.com
|
||||
sync.server.client_id=[your client-id]
|
||||
sync.encryption_secret=[your encryption secret]
|
||||
```
|
||||
|
||||
The docker-compose images store data in a docker volume named
|
||||
`taskchampion-sync-server_data`. This volume contains all of the task data, as
|
||||
well as the TLS certificate information. It will persist over restarts, in a
|
||||
typical Docker installation. The docker containers will start automatically on
|
||||
system startup. See the docker-compose documentation for more information.
|
||||
|
||||
### Running the Binary
|
||||
|
||||
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.
|
||||
`--port` gives the port on which the HTTP server runs.
|
||||
|
||||
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>`.
|
||||
|
|
@ -36,52 +75,9 @@ 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

## Building
|
||||
|
||||
### As container
|
||||
|
||||
To build the container execute the following commands.
|
||||
```sh
|
||||
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.
|
||||
```sh
|
||||
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.
|
||||
```sh
|
||||
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.
|
||||
```sh
|
||||
mkdir -p /my/taskchampion-sync-server
|
||||
chown -R 100:100 /my/taskchampion-sync-server
|
||||
