Docker setup on AWS

Choose a Ubuntu AMI rather that Amazon Linux 2 (AL2), because there wasn’t a specific repository for AL2.

Found instructions for installing Docker on AL2 on https://docs.aws.amazon.com/AmazonECS/latest/developerguide/create-container-image.html#create-container-image-prerequisites

Install using the repository

From https://docs.docker.com/engine/install/ubuntu/#set-up-the-repository

sudo apt-get update
sudo apt-get install \
    ca-certificates \
    curl \
    gnupg \
    lsb-release

Add Docker’s official GPG key:

 sudo mkdir -p /etc/apt/keyrings
 curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

Use the following command to set up the repository:

 echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

Install Docker engine

 sudo apt-get update
 sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin
sudo systemctl enable containerd.service
sudo systemctl enable docker.service

Post-installation steps for Linux

So you don’t have to do sudo everytime but adding the docker group grants privileges equivalent to the root user. From https://docs.docker.com/engine/install/linux-postinstall/

 sudo groupadd docker
 sudo usermod -aG docker $USER

Log out and log back in so that your group membership is re-evaluated.

On Linux, you can also run the following command to activate the changes to groups:

 newgrp docker 

Verify that you can run docker commands without sudo.

 docker run hello-world
