docker build -t qore:fedora-27 images/fedora-27
optionally tag the image as latest
docker tag qore:fedora-27 qore:latest
Either run directly qore
docker run --rm qore:latest qore --help
docker run --rm qore:latest qore -ne 'printf("%N\n", {"hello": "world"});'
or start bash with qore installed
docker run -it --rm qore:latest bash
see the example dir for a bash script that may help you and possibly create a bash alias
alias qore_docker="~/qore_docker/run.sh latest"
then simply run the alias
[~] $ qore_docker -nX 'replace("qore is bad", "bad", "the best")'
"qore is the best"
