What is the created time in docker images command?

Question

What is the CREATED time exactly when you give this command?

docker images

It gives the time like 3 months ago, or 9 days ago.

Is it the time it was uploaded to docker hub?

Even for the locally created images, it shows like 15 minutes ago, while I had created just a minute ago.

Answer 1

It should be the date of the latest docker build run by the image owner, as defined in the image/image.go file, which can be found in the container once the image has been run.

You can inspect low-level image info to see its exact value with:

docker inspect -f '{{.Created}}' hello-world

where 'hello-world' is the name of your image.

If you are in a VM, the timestamp might not be precise for local images, as your VM clock might not be precisely synchronized (by typing 'date', I see mine is synchronized, but on UTC: one hour shift).
