After problems with one of the last versions of Windows’ version of Docker I have reinstalled Docker (from the Docker site, and updated it twice, up to version 4.42.1) and during the configuration I’ve observed that Docker installs some images:
alpine/socat
docker/jcat
The first one appeared first. At first I thought it was due to the configuration options, but since it had never done that before, I deleted that image and set the same options again to see if that was the reason. This time the first one didn’t appear, but the second one did, and not right away.
After a cursory search of the Internet, I decided to delete this image as well. For a while, it did not appear (several minutes), until, after browsing a few options from the menu on the left, it appeared again (the second one).
I thought maybe he needed it to display some Extensions or Docker Hub folder so I deleted it again and looked at those options again, but it didn’t appear, so that didn’t confirm my suspicion. After some time it appeared again.
Now I’m wondering, despite all these inconsistencies (new behavior, self-installing images, different images appearing at different times), is this nevertheless normal Docker behavior, or do I have a hole in my system and someone is trying to install more holes in the system for me, this time in Docker?
