Dockerfile

# Dockerfile for agagd application local development environment.
#
# In addition to environment variables used by the application, the entrypoint script is affected by the following. docker-compose.yml sets reasonable defaults for a development environment:
# * DB_HOST - database hostname
# * DB_PORT - database port
# * APP_DB_NAME - name of the database to use
# * AGAGD_USER - database username
# * MYSQL_PASSWORD - database password (the docker entrypoint sets MYSQL_PASS to this value for app compatibility)
