Docker Automation :

Run a small number of docker containers from docker build to actual run.

Docker Orchestrisation

This is an automated way to run, manage, deploy & auto-scale docker containers. There are other frameworks that don’t use docker rather other container service but the technical concept is still the same. AWS is a cloud service provider to run & deploy not just docker containters but a wide variety of applications and frameworks. It comes under the PaaS Model (Platform as a Service) as well as a bit into IaaS (Infrastructure as a Service) model.

Cool Example of Docker

I ran MacOSX from docker using QEMU and container from sidekick.

sudo docker run --name macosx \
    --device /dev/kvm \
    --device /dev/snd \
    -e AUDIO_DRIVER=pa,server=unix:/tmp/pulseaudio.socket \
    -v "/run/user/$(id -u)/pulse/native:/tmp/pulseaudio.socket" \
    -v /tmp/.X11-unix:/tmp/.X11-unix \
    -e PULSE_SERVER=unix:/tmp/pulseaudio.socket \
    --privileged \
    --net host \
    --cap-add=ALL \
    -e SMP=4 \
    -e CORES=4 \
    -e RAM=16 \
    -p 50922:10022 \
    -v /tmp/.X11-unix:/tmp/.X11-unix \
    -e EXTRA='-usb -device usb-host,hostbus=1,hostaddr=2' \
    -v /dev:/dev \
    -v /lib/modules:/lib/modules \
    -e "DISPLAY=${DISPLAY:-:0.0}" \
