Deploying with Docker

Deploying with Docker allows you to run Session Group Server on any operating system without having to deal with OS-specific quirks.
In some instances it might be more beginner-friendly, however it is also slightly more demanding in terms of resource usage.

Requirements

A server with Docker installed
git

Setup

Step 1: Clone the repository

git clone https://github.com/nielsandriesse/session-open-group-server.git
cd session-open-group-server

Step 2: Create or pull a docker image

sudo docker build -t session-open-group-server .

This will create an image for our container called session-open-group-server.
If your device can't handle the building process or you don't want to build on your server machine, in the next step you will be told how to use a pre-built image.

Step 3: Run the docker image

sudo docker run \
    --name session-open-group \
    --restart unless-stopped \
    -v session-open-group-data:/session-open-group-server/target/release/data \
    -p 9999:80 \
    session-open-group-server

This will start an auto-restarting container named session-open-group on port 9999, with a persistent data volume called session-open-group-data, based on the image we've created in the step before.
If you've chosen to use a pre-built image, replace session-open-group-server with massiveboxe/session-open-group.

Tip: You can add the -d flag after docker run to start the container in the background.

Step 4: Configure

This command will connect you to the container's internal command line:

sudo docker exec -it session-open-group /bin/sh

And this one will take you to the path where the server binary is stored:

cd /session-open-group-server/target/release

You can now edit the configuration as you please. You can follow the steps indicated in the README.md and the CLI reference, just remember to use ./session-open-group-server instead of session-open-group-server or /usr/bin/session-open-group-server. Examples:

Print the server URL: ./session-open-group-server --print-url
Become moderator of a room: ./session-open-group-server --add-moderator {your_session_id} {room_id}

Once you're done configuring, exit the internal command line with this command:

exit

You don't need to restart the container after changing the configuration.

Step 5: Enjoy

Your Session Open Groups server is ready.
You can join it using the link sent on server startup or with the --print-url flag. However, don't forget to add the port! Since the server is running in a Docker container serving on port 9999, this is the correct URL:

http://[host_name_or_ip]:9999/[room_id]?public_key=[public_key]

(Replace 9999 with whatever port you chose in the docker run step if you didn't use 9999)
