I've used docker for process isolation at two companies now. In both cases, we were executing things on the server based on customer input values, and desired the isolation to help ensure safety.
In the first company, these were one-off import jobs that would import customer information from a URL they provided.
In the other, these are long-running daemons for a multi-tenant service, and I need to reduce the risk that one customer could exploit the system and disrupt the other customers or gain access to their data.
I have some other experiments in play right now in which I am packaging up various services as docker containers, but this is currently non-production.
