Words of caution

• Docker is limited to the resources you give it. If your dev machine is less than awesome, your Docker container will be much less than awesome
• Docker is only allowed access to what you give it and may take some extra work to get running
• Some workplaces may not be comfortable with Docker
• Some use-cases may require direct access to the hardware and are incompatible with a container system
  • Sometimes computers do math differently
• Containers require proper setup!
