Cannot Connect to the Docker Daemon: Is the Docker Daemon Running?

• Hi everyone,

 

I'm encountering an issue with Docker that I hope someone can help me resolve. When attempting to run Docker commands, I keep receiving the following error message:

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the Docker daemon running?

Here’s a detailed description of the problem and what I’ve tried so far:

 

Problem Description:

 

I am using Docker on [Your OS, e.g., Ubuntu 20.04, Windows 10, macOS Monterey].

The error message appears whenever I try to execute Docker commands, such as docker ps, docker run, etc.

The Docker service is supposed to be running, but it seems like my system is unable to communicate with the Docker daemon.

 

Steps I’ve Tried:

 

Checked Docker Service Status:

 

I ran sudo systemctl status docker to check the status of the Docker service. It indicates that the service is not active or running. The output looks like:

yaml

Copy code

● docker.service - Docker Application Container Engine

   Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)

   Active: inactive (dead)

Restarted Docker Service:

 

I attempted to restart Docker using sudo systemctl restart docker, but it did not resolve the issue. The service status still shows as inactive.

 

Checked Docker Socket:

 

The Docker socket file /var/run/docker.sock does exist, but its permissions are set to:

arduino

Copy code

srw-rw---- 1 root docker 0 Jul 31 10:30 /var/run/docker.sock

My user is part of the docker group, and I’ve ensured proper permissions are set.

 

Checked Docker Logs:

 

I examined the Docker logs using journalctl -u docker.service but did not find any clear errors or clues as to why the Docker daemon isn’t running.

 

Reinstalled Docker:

 

As a last resort, I uninstalled and reinstalled Docker following the official documentation for my operating system. Despite this, the issue persists.

 

Checked System Resources:

 

I verified that there is sufficient disk space and memory available on the system.

 

Consulted Docker Documentation:

 

I reviewed Docker’s troubleshooting documentation and tried the recommended fixes, but none seem to address this specific issue.

 

Additional Information:

 

Docker version: [e.g., Docker Engine 20.10.7]

Kernel version: [e.g., Linux 5.4.0-66-generic]

Any recent changes or updates to the system or Docker configuration before the issue started?

I would greatly appreciate any guidance or suggestions on how to resolve this issue. If there are any additional logs or diagnostic information that I should check, please let me know. Thank you in advance for your help!
