Join Arthur Ulfeldt for an in-depth discussion in this video Images, part of Learning Docker.
- [Voiceover] We've used quite a few images…thus far through this course,…and now let's spend a little bit of time…talking about how to manage and keep track…of the images we're working with.…So you can list the images…that you've already downloaded…with the docker images command.…It only lists the images you've already downloaded.…It's not the tool for finding images to download.…We'll cover that later.…So,…docker images.…Alright I can see there are several images…on my machine.…Now spend a little time,…this is where it came from,…the tag on it, this one has no name and no tag.…
The image ID we've mentioned before.…So wanna mention the size here.…Because these images share…a great deal of their underlying data,…you don't sum up the sizes here…to get the total amount of space the docker's using.…In this case, all of these 122 megabyte images here…are actually the same 122 megabytes,…with different names on them.…Docker is much more space efficient…than it would look like just from…looking at this list.…So don't get scared by that.…
