- seppel 7y agoWell, not if you use Docker on Windows or Mac. But these are technicalities that don't matter that much. Unless you are writing kernel drivers or you need to tweak certain kernel parameters, running in a Docker container is very much as running in a VM. With the same responsibilities, e.g., setting up an init process.
