Server prerequisites

  • Docker

  • Linux

The Monarch server was primarily developed and tested on Ubuntu. Native installation of the server will only work on Linux systems (specifically, systems that allow direct access to Docker containers via interface). However, the Monarch client has been tested on and can run on Mac OS and Windows.

Note: Installing Monarch in a container will work on other Unix-like systems, however, you'd need to specify which ports you'd be likely to open in the install script, so that the host machine (if any) would give external connections access to the container. These ports would be your HTTP(S) and multiplayer endpoints, specified in the Monarch configuration file.

For system requirements, see the requirements for Docker Desktop on .

Installing Monarch server

. Once cloned, with bash, run scripts/install-monarch.sh. The Docker network for monarch containers, encryption keys / certificates as well as the SQL container instance for storage will be set up automatically. The monarch binary is saved as $HOME/.local/bin/monarch. 

# run on the server
git clone https://github.com/pygrum/monarch && \
    cd monarch && \
    bash scripts/install-monarch.sh

Alternatively, you may install monarch in a Linux container with scripts/docker-install-monarch.sh. In this case, Monarch is started with a script in $HOME/.local/bin called monarch.sh. It is important to remember that if this container is running in a host, then it will need to be given access to certain ports for HTTP(S) and multiplayer listeners.

Once installation has finished, you may wish to edit the default configuration placed in $HOME/.monarch/monarch.yaml.

The monarch client is just a binary, which can be downloaded from the page. All that's required to start the client is the configuration file generated by the server.
