From @Nick_Craver (Twitter):
docker run --rm -it $(docker build -q .)Using the -q output (just the hash) from a container build, run it, then discard it (--rm) on exit.
Overall: one command to build, run, and delete...without a tag and local image created while testing your docker build scripts. Neat.

:: Hello from Docker!
:: This message shows that your installation appears to be working correctly.
::
:: To generate this message, Docker took the following steps:
:: 1. The Docker client contacted the Docker daemon.
:: 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
:: (amd64)
:: 3. The Docker daemon created a new container from that image which runs the
:: executable that produces the output you are currently reading.
:: 4. The Docker daemon streamed that output to the Docker client, which sent it
:: to your terminal.
::
:: To try something more ambitious, you can run an Ubuntu container with:
:: $ docker run -it ubuntu bash
:: now let's see currently running images
docker ps
