I’m encountering an issue with Docker Desktop on my Mac where it fails to accurately determine the disk size of an image. Has anyone else experienced this problem, and what solutions or workarounds exist to address it?

I’m in a bit of a predicament with Docker Desktop on my Mac, and I’m really hoping to get some insights from you all. Lately, I’ve run into this annoying issue where Docker doesn’t seem to accurately determine the disk size of my images. It just shows some weird numbers or sometimes nothing at all, which makes it impossible for me to assess if I’m running out of space or if there’s a problem with my setup.

I first noticed this when I was trying to clean up some images to free up space. I was using the `docker images` command, expecting to see a clear breakdown of what takes up what. Instead, I was greeted with a dashboard that looked more like a poorly drawn abstract painting than useful information—totally confusing! Seriously, I’m scratching my head over here.

I’ve tried restarting Docker and my computer, thinking it might just be a temporary glitch, but no luck. I even looked into updating Docker Desktop, hoping that the latest version might address this issue, but that didn’t help either. It really feels like I’m hitting a wall here. What’s even weirder is that last week it was fine; I could see the disk sizes just like I’m supposed to.

Has anyone else dealt with this? If so, what did you do to get around it? I’ve heard people suggest manually checking the disk usage via the command line, but I’m not entirely sure how to do that proficiently or if it’s a workaround worth pursuing. I’d love to know if anyone has found a reliable solution or any tips that could steer me in the right direction.

I’m all ears for anything you’ve got—whether it’s a command I can run, a specific setting I might have overlooked, or even just a general reassurance that I’m not alone in this. Life’s too short for these tech headaches, right? Thanks in advance for any advice you can share!

    1. Sounds like you’re having a frustrating time with Docker Desktop on your Mac! That disk size issue can really be a pain. Here’s a few things you might wanna try:

      • Check Disk Usage via CLI: You can run this command in your terminal to see how much space your images and containers are using:

        docker system df

        This should give you a breakdown of your disk usage!

      • Clean Up: If you’re looking to free up some space, try this:

        docker system prune

        Just be careful with it since it removes unused data. It might help clear some of the confusion!

      • Reset Docker: If all else fails and you’re still seeing funky numbers, you can reset Docker to factory settings. Go to Docker > Preferences > Reset and choose ‘Reset to factory defaults’. Just keep in mind that this will wipe your current Docker setup.

      Also, it might just be a temporary glitch with the Docker app itself. Sometimes restarting the app or ensuring your macOS is updated can help too!

      You’re definitely not alone in this tech headache! Sometimes tools act up, and it’s super annoying. Hopefully, one of these suggestions will help you out!


    2. The issue you’re experiencing with Docker Desktop on your Mac regarding the inaccurate disk size representation of your images can certainly be frustrating. It’s not uncommon for users to encounter such discrepancies, especially after updates or changes in configuration. If restarting both Docker and your system didn’t resolve the issue, consider checking Docker’s settings and logs for any anomalies. Additionally, performing a system prune could help clean up any dangling images or unused data that might be contributing to the confusion. You can execute the command docker system prune to clear out unused containers, networks, and images. Just be cautious, as this will remove all stopped containers and all dangling images, so make sure to back up anything you might need.

      For a more detailed view of storage usage, you can manually check the disk usage via the command line with the command docker system df. This will give you a breakdown of image sizes, container sizes, and any space used by volumes. If everything else fails, consider uninstalling and reinstalling Docker Desktop. Sometimes a fresh install can resolve underlying issues that aren’t immediately apparent. Lastly, don’t hesitate to check forums or the Docker community for similar occurrences, as many users share their insights and solutions for common problems like this one. You’re definitely not alone, and with a bit of troubleshooting, you should be able to get past this hurdle.
