This will start a Docker container running the Simian Army:
docker pull mlafeldt/simianarmy docker run -d [-e CONFD_OPTS="..."] mlafeldt/simianarmy
See Configuration on how to configure the Simian Army.
If you want to access Simian Army's REST API, you additionally need to expose port 8080 like this:
docker run -d -p 8080:8080 mlafeldt/simianarmy
This will drop you into a login shell, which is useful for debugging:
docker run -it --rm mlafeldt/simianarmy /bin/bash
In general, the image will execute any command you pass on the command line.
