Some questions. I got clean server just ubuntu. Now after installation i dont know:
- should i install any “software” like iptables (firewall) or somethink else? Or docker over this ?
- should i know/learn hot to configure somethink more on server?
- should i connecting via ssh as non admin ? how to do it ? just create an new user only ?
for example - after install a docker - "If you would like to use Docker as a non-root user, you should now consider
adding your user to the “docker” group with something like:
sudo usermod -aG docker" Should i do it ?
