Install docker into Ubuntu instance (based on docs.docker.com)

bootstrap-docker-ubuntu.sh

#!/bin/bash

# update apt repos
sudo apt-get update

# install curl and keyring (certificate) support
sudo apt-get install -y \
  ca-certificates \
  curl \
  python3-pip \
  python-is-python3
  
sudo install -m 0755 -d /etc/apt/keyrings

# Add Docker's official GPG key:
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

# Add the repository to Apt sources:
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update

# install docker (et al)
sudo apt-get install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

# verify
sudo docker run hello-world

Just a simple shell script that installs docker and its dependencies on Ubuntu. Taken from the docker documentation. I threw this together to remember how to spin up Multipass VMs.

curl

bash <(curl -sL https://bit.ly/bootstrap-docker-ubuntu)

wget
