Interactively create dockerfiles

• You have a command in your path, FROM.
• You type FROM some-image:whatever
• It does something like this:

```bash echo “FROM $@” > ./Dockerfile echo » ./Dockerfile

echo “FROM $@” > $tmpfile echo “ADD $path/shell /dockerize/shell” » $tmpfile tail -n +2 Dockerfile » $tmpfile || true echo “ENTRYPOINT /dockerize/shell” » tmpfile

docker run –build -v$(pwd)/Dockerfile:/dockerize/Dockerfile

Then each command that you type, assuming it succeded, gets added to the Dockerfile.
