This docker container is based on
alpine:3.3 for minimal container size with Shallot compiled at container build time.
The container exposes
/shallot which is a working directory of the application. If you choose to save output to file, this is where it will be created.
$ docker run -d -v ~/shallot-output:/shallot tmiklas/alpine-shallot -f test-key.txt ^test
The same as used with Shallot - see LICENSE
