MarginaliaSearch/run/install.sh

#!/bin/bash

#
# This script will set up a Marginalia instance in a given directory.
# It will create a docker-compose.yml file, and a directory structure
# with the necessary files.  It will also create a MariaDB database
# in docker, and run the flyway migrations to set up the database.
#
# After the script is run, the instance can be started with
# $ docker-compose up -d
#
# The instance can be stopped with
# $ docker-compose down -v
#
# It is likely that you will want to edit the docker-compose.yml file
# to change the ports that the services are exposed on, and to change
# the volumes that are mounted.  The default configuration is provided
# a starting point.
