I am experiencing an issue where my Docker containers are running, yet they are not appearing in the output of the docker ps command. Has anyone encountered this problem or knows what might be causing it? Any insights on how to resolve this would be appreciated.

I’ve run into a really puzzling issue with Docker, and I’m hoping someone here might have some insights or have experienced something similar. So, I’ve got several containers that I set up and started running without any apparent problems. I mean, when I first built and ran them, everything seemed to be going smoothly. However, when I run the `docker ps` command to check on their status, I see… basically nothing—a blank output. It’s like they’ve vanished into thin air!

At first, I thought maybe there was something wrong with my command or filters I had set, but after checking several times, I’m pretty sure I’m running it correctly. It’s just strange because I can still see the containers through other commands like `docker container ls -a`, which shows them all, including the stopped ones. But when it comes to actively running ones, there’s dead silence. It’s super frustrating because I’m trying to diagnose some issues in the running ones, but without any visibility, it’s like trying to find a needle in a haystack.

I’ve tried restarting the Docker daemon and even rebooting my machine, thinking it could be a glitch, but the problem persists. I checked the Docker logs, and everything seems normal there, too. It’s not like my containers are crashing—they just won’t show up in the standard list of running containers.

Has anyone else faced this issue? I’m wondering if it might be related to my Docker version or configuration. Also, could there be any recent updates or changes that might have triggered this? I’m really scratching my head over this one. Any tips or troubleshooting steps you could suggest would be greatly appreciated! I’m keen to hear if there’s a simple solution or if I’m overlooking something obvious. Thanks in advance!

      Docker Container Issue

      Docker Container Confusion

      Oh man, I totally get where you’re coming from! It’s really weird when you’re staring at a blank output from docker ps and can’t see your running containers. So frustrating! Here are a few things you can check or try:

      • Docker Version: Maybe check if your Docker is up to date? Sometimes, bugs get fixed in newer versions. You can check your version with docker --version.
      • Container State: Since you can see them in docker container ls -a, it might be helpful to check if the containers are even running or if they exited immediately. You can look at their statuses in that command’s output.
      • Check Filters: Are you using any filters with docker ps? Sometimes they can mess with what gets displayed. Just running docker ps without any flags might help.
      • Docker Logs: You mentioned checking logs, but double-checking the logs for specific containers might help. Use docker logs [container_id] on the containers you suspect are running but not showing up.

      Also, if you’ve recently made changes, especially around networking or volumes, that could affect visibility. Maybe a restart of Docker could help—at least that’s a classic troubleshooting step!

      If all else fails, you might want to try pulling your Docker images again or even rebuilding your containers. Could be a long shot, but sometimes it clears up weird issues.

      Hope something here helps! Don’t lose hope, we’ve all been there!

      It sounds like you’re encountering an unusual issue with Docker where the expected output from the `docker ps` command isn’t showing any running containers. Since you can see all containers, including the stopped ones, with `docker container ls -a`, it’s likely that the containers are either stopped immediately after starting or there are some underlying issues preventing them from running properly. One possibility is that the containers may be exiting due to a misconfiguration or an unhandled exception in the application they’re running. To investigate further, you can check the logs of individual containers using `docker logs ` to see if they are providing any error messages or clues regarding their status. Additionally, running `docker inspect ` might reveal more information about their state and any exit codes generated, which can help diagnose the issue further.

      Given that restarting the Docker daemon and your machine didn’t resolve the problem, consider checking for any issues with your Docker installation. Ensure you’re running the latest stable version of Docker, as updates sometimes resolve bugs that might affect container visibility. You can also explore your Docker’s configuration files and settings to see if there are any restrictions or filters inadvertently applied. Additionally, inspecting system resource usage (like CPU and memory) could be insightful, as resource constraints can also prevent containers from starting correctly. If the issue persists after these checks, it could be useful to seek help from the community or report it on Docker’s issue tracker, providing relevant details about your environment and any error logs you’ve gathered.
