What is the solution for "dial unix /var/run/docker.sock: connect: permission denied" error despite the group permissions appearing to be accurate?

edit

There could be several reasons for this error despite the group permissions being accurate. Here are a few possible solutions:

1. Check if the user is added to the docker group: Run the following command to verify if the current user is part of the docker group:

$ id -nG

If the output does not include "docker", the user needs to be added to the docker group using the following command:

$ sudo usermod -aG docker $USER

1. Restart Docker service: Sometimes, the docker service may not have picked up the updated group permissions. Restarting the Docker service might solve the issue.

$ sudo service docker restart

1. Check if the socket file exists: Verify if the socket file "/var/run/docker.sock" exists and is accessible. Run the following command to check the permissions of the docker socket file:

$ ls -l /var/run/docker.sock

The output should show the group as "docker" and the permissions as "srw-rw----". If there is no file, try restarting the Docker service.

1. Run Docker commands with sudo: If none of the above solutions work, try running the Docker commands with sudo. However, this solution is not recommended as it can cause further security issues.

$ sudo docker ps

Fixing this issue is important for running Docker commands without any impediments.
