> Currently the docker containerizer does a docker pull on each run, and this has several downsides:
> 1. Not able to run local images
> 2. Require to contact registry server on each run, therefore docker run becomes unavailable if the registry server is down. Also has scalability limits.
> We want to avoid doing a pull everytime. The downside ofcourse is that images without explicit tags (:latest) will not get the most updated version, but this is the same behavior when calling docker run on the cli.
