Docker toolbox
to build the image use docker build . ("." will point to docker file at current path)
after the docker build finishes use docker run imagename
but this will not expose the port by default use docker run -p 3000:3000 imagename
but if we are using docker toolbox we won't be able to access localhost:3000 we will have to use ip from docker quickstart of docker instance example:- http://192.168.99.100:3000/ (here ip is of docker instance )
