To run Docker without sudo, you need to add your current user to the Docker group. This can be done following these steps:
1. To add your user to the Docker group, you can use the following command:
`sudo usermod -aG docker ${USER}`1. Here, `usermod` is a utility that modifies a user’s system account, `-aG` is used to append the groups mentioned by the `-G` option to the current set of groups that the user is part of.
1. In this case, the `${USER}` variable represents your current user.
1. You would need to log out and log back in so that your group membership is re-evaluated. If testing on a virtual machine, it may be necessary to restart the virtual machine for changes to take effect.
1. You could also use the following command to apply the new group membership immediately:
`su – ${USER}`1. Now, you should be able to use Docker without requiring sudo.
1. To verify, you can try running:
`docker run hello-world`This should run without needing sudo.
Be aware that adding a user to the Docker group essentially grants them administrative privileges. This is because Docker command execution is equivalent to having root rights on the system, meaning the user can gain full control of your system.
Consider the security risks and depending on the sensitivity of your data and code, take the necessary precautions.
