Removing sudo password is typically not a good practice. If you’re a seasoned system administrator, or you’re the only one using your own desktop, being prompted for a sudo password can get really annoying. Here’s how to stop getting prompted every time you run sudo.
Run visudo.
sudo visudo |
sudo visudo
Edit the sudo line and set to below.
%sudo ALL=(ALL) NOPASSWD: ALL |
%sudo ALL=(ALL) NOPASSWD: ALL
Save file.
Here’s an alternate way to give Linux users sudo access by adding them to the wheel group. Most Linux systems come with the wheel group already predefined. By adding users to the wheel group, they now have the ability to sudo and run root commands. The wheel group is in the sudoers file for Redhat, Centos, Debian and Ubuntu.
usermod -aG wheel username |
usermod -aG wheel username
What’s in the /etc/sudoers.d/ directory? It’s a group of files with the following format as displayed in the code below. In the example, the file allows a Linux group or an AD group to assume the role of root, via the sudo command. As long as the group uses the correct format, and is located inside the /etc/sudoers.d/ directory, that group will have access to root.
%groupname ALL=(ALL) NOPASSWD: ALL |
%groupname ALL=(ALL) NOPASSWD: ALL
Run Docker without sudo. Add user to docker group. Login as docker using newgrp.
sudo gpasswd -a $user docker newgrp docker |
sudo gpasswd -a $user docker newgrp docker
You can now run the following commands without sudo.
docker ps
docker images |
docker ps docker images
Every time you open a new terminal , just run.
newgrp docker |
newgrp docker
