Configure Docker to start on boot

Most current Linux distributions (RHEL, CentOS, Fedora, Debian, Ubuntu 16.04 and higher) use systemd to manage which services start when the system boots. On Debian and Ubuntu, the Docker service is configured to start on boot by default. To automatically start Docker and Containerd on boot for other distros, use the commands below:

 sudo systemctl enable docker.service

 sudo systemctl enable containerd.service

UPDATE (27 April 2022)

Docker CE Install

sudo amazon-linux-extras install docker
sudo service docker start
sudo usermod -a -G docker ec2-user

RSA 2048 Key-Pair Generation

Generate Private Key

openssl genrsa -out mykey.pem 2048

Generate Public key using Private Key

openssl rsa -in mykey.pem -pubout > mykey.pub

For 10.0.0.0/16, we can create subnets between 10.0.0.0/24 to 10.0.255.0/24, e.g. 10.0.8.0/24 would work.

Let's say we've got CIDR address 10.20.30.40 - that can fall for example into these subnets:

10.0.0.0/8 - /8 means only the first byte (10.) in the address is the network address.
10.20.0.0/16 - /16 means the first two bytes (10.20.) are network.
10.20.30.0/24 - /24 means the first three bytes (10.20.30.) are network.
10.20.30.40/32 - /32 covers the whole address (10.20.30.40) and sometimes this notation is used to explicitly say it's a host address. AWS uses that a lot.

Delete node_modules folder recursively from a specified path using command line
