#Airflow docker file install

In contrast to a ' container image' that is the stored static contents, a ' container' normally refers to the running instance, the thing that is being executed. Static here means that the container image is not running, it's not being executed, it's only the packaged files and metadata. What is a Container Image ¶Ī container is run from a container image.Ī container image is a static version of all the files, environment variables, and the default command/program that should be present in a container. This way, containers consume little resources, an amount comparable to running the processes directly (a virtual machine would consume much more).Ĭontainers also have their own isolated running processes (commonly just one process), file system, and network, simplifying deployment, security, development, etc. This just means that they are very lightweight (compared to full virtual machines emulating an entire operating system). Linux containers run using the same Linux kernel of the host (machine, virtual machine, cloud server, etc).
