Does the docker image run directly on their base virtualization platform or does it run on top of another OS (that I install) that runs on their virtualization platform? I have an OS in my docker image already, so..
- eknkc 11y agoBut you don't have an OS in your docker image really. There's no kernel, no init or system services running if you don't do that yourself. A running docker container is just a process on the host OS with it's own environment. ECS abstracts this away, and from your perspective, containers are running on their virtualization platform.
- xienze 11y agoThe "OS" part of a Docker image is really just a minimal environment that "looks and feels" like Ubuntu, CentOS, etc. You're not actually virtualizing a full OS. Running a Docker image is essentially equivalent to running a process (whatever process is defined by your image, i.e. Apache, MySQL, etc.).
