Letting conf.yml be an instruction file,

$ docker run -i jkawamoto/roadie-gcp < conf.yml

starts Roadie-GCP with the instruction. You also specify an instruction file instead of STDIN by

$ docker run -i jkawamoto/roadie-gcp -c /path/to/conf.yml

Roadie-GCP will shutdown your VM after finishing instructions. Thus, scope is required. To prevent this behavior, use --no-shutdown option.

The full description of arguments is below.

usage: docker run -i jkawamoto/roadie-gcp [-h] [-c CONF] [--no-shutdown]

Read an instruction from STDIN and run programs in that way.

optional arguments:
  -h, --help            show this help message and exit
  -c CONF, --conf CONF  Specify an instruction YAML file instead of STDIN.
  --no-shutdown         Not shutdown after finishing tasks.
  --no-unzip            Not unzip zipped files.
