# to build the container with apps use the following command:
# docker build --build-arg METAPHACTORY_VERSION=5.6.0 -t metaphactory-with-apps:5.6.0 .
# to run the container with one example app use the following command:
# docker run --detach --publish 10214:8080 --env MP_APP_1=/installedapps/eventsubscriber-example --name metaphactory-test metaphactory-with-apps
# to inspect the container created using the previous command use the following command:
# docker inspect metaphactory-test
# to run a command within the container created using the previous command use the following command:
# docker exec -ti metaphactory-test bash
# to delete the container created using the previous command use the following command:
# docker rm -f metaphactory-test
