Setup Ubuntu AWS

Setup + add swap and instal Docker & docker-compose

01 - Add Swap:

• check if your instance already has a swap file or partition:

sudo swapon --show

• Create 1GB swap file called /swapfile. You can adjust the size of the file by changing the number after -l.

sudo fallocate -l 1G /swapfile

sudo chmod 600 /swapfile

sudo mkswap /swapfile

• Enable the swap file

sudo swapon /swapfile

• Add an entry to the /etc/fstab file to ensure that the swap file is automatically enabled after every reboot

/swapfile swap swap defaults 0 0

• Verify the swap file

sudo swapon --show
free -h

02 - Docker Installation:

• Update your existing packages

sudo apt update

• Install a prerequisite packages which let apt utilize HTTPS:

sudo apt install apt-transport-https ca-certificates curl software-properties-common

• Add GPG key for the official Docker repo to the Ubuntu system:

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

• Add the Docker repo to APT sources:

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable"

• Update the database with the Docker packages from the added repo:

sudo apt update

• install Docker and Docker compose + Docker CE command line interface + containerd

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin

• Test verify the docker setup:

sudo docker --version
docker compose version
sudo docker run hello-world
sudo docker images
sudo docker ps -a

• To avoid using sudo for docker activities, add your username to the Docker Group:

sudo usermod -aG docker {your_username}

03 - Install necessary dependencies

sudo apt install -y python3-pip python3-venv python3-dev python3-pandas git curl
