Docker without sudo
Steps to Enable Docker Without sudo
Follow these steps to configure Docker for non-root usage:
1. Create the docker Group
The docker group allows users to execute Docker commands without requiring root privileges. Run the following command to create the group:
1
sudo groupadd docker
If the group already exists, this command will have no effect.
2. Add Your User to the docker Group
Add your current user to the docker group to grant the necessary permissions:
1
sudo gpasswd -a $USER docker
Replace $USER with your username if you’re not running this command as the logged-in user.
3. Apply the Group Changes
To apply the group changes without logging out and back in, use the newgrp command:
1
newgrp docker
This command switches your session to the updated group.
4. Test Docker Without sudo
Verify that Docker works without sudo by running the following command:
1
docker run hello-world
If everything is configured correctly, you should see the “Hello from Docker!” message.
For more details, refer to the official Docker documentation or the Ask Ubuntu thread.
