I’m using docker for setting up my container on a CoreOS instance.

I’ve set my container as a services, so each time the CoreOS instance is up the containers are set up.

However, the first time the CoreOS instance is booted docker must to download each image locally. This process is performed in backgroung.

I’d like to know about the download process. Is there some way to get information about this process?

You could check the docker service log, use tcpdump, strace, etc. Depends on what you want to know and how granular you are willing to get.
