This video shows you how to use docker commands to remove a base OS image from a Windows container host, after identifying and removing dependencies.
- [Voiceover] We've seen the relationship…between containers and images already.…Images are the saved states with all the necessary files,…applications, and runtimes separated into layers,…while containers are the active space…where the images run.…Here I have the folder that is the default location…for images that have been pulled or created…on a Windows machine, and each of these folders…represents a layer of an image that's been saved.…Some of these layers are relatively small,…this one only 132 meg.…
Others may be a little bit larger, almost a gig.…This is probably the nanoserver base image.…While others can be a little more substantial.…As we see this count up to about six and a half gigs,…this is most likely one of the layers…of our Windows server core image.…Occasionally you're going to assess how containers…are being used in your environment.…And if you need to remove a base image,…it will be important to remember…all of the layers involved and to remove them properly…rather than simply try to delete files from the hard drive.…
