Dockerfile

The simplest dockerfile which starts IRIS and imports Installer.cls and then runs the Installer.setup method, which creates IRISAPP Namespace and imports ObjectScript code from /src folder into it. Use the related docker-compose.yml to easily setup additional parametes like port number and where you map keys and host folders. Use .env/ file to adjust the dockerfile being used in docker-compose.
