My essential setup for a new VPS/Ubuntu server.

Setup swap

sudo fallocate -l 1G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
sudo cp /etc/fstab /etc/fstab.bkp_before_swap_config
echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab
sudo sysctl vm.swappiness=10
sudo sh -c "echo 'vm.swappiness=10' >> /etc/sysctl.conf"

Setup docker and add current user to docker group

sudo apt install docker-compose docker.io
sudo usermod -aG docker $USER

Show IP address on tty login

sudo nano /etc/issue

Add the following lines to display the IP address of your network interface (replace enp2s0 with your actual interface name):

Ubuntu \n \l

enp2s0 (IPv4): \4{enp2s0}
enp2s0 (IPv6): \6{enp2s0}

That's it for this post, thanks for reading!
