install docker

Run these commands

  • sudo apt-get update

  • sudo apt-get install \
  apt-transport-https \
  ca-certificates \
  curl \
  gnupg-agent \
  software-properties-common

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

  • sudo add-apt-repository \
 "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
 $(lsb_release -cs) \
 stable"

Some times the above command gives an error: malformed input, in that case, please do

  • Add the line
    • deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable to /etc/apt/sources.list.d/addtional-repositories.list
    • (create the file if it does not exist)

Rest of the steps are the same

  • sudo apt-get update
  • sudo apt-get install docker-ce docker-ce-cli containerd.io

Add yourself to the docker group

  • sudo groupadd docker
  • sudo usermod -aG docker $USER

Post this you should logout and login again, but if you can’t use this command instead

  • newgrp docker

Docker Compose Install

Run

  • sudo curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

To install a different version of Compose, substitute 1.24.1 with the version of Compose you want to use.

  • sudo chmod +x /usr/local/bin/docker-compose

Raspberry Pi Install

Docker

sudo apt install docker.io not the most updated, but pretty updated, since for a PI, its arm and currently its a bit flimsy in support, so use the ubuntu repos first

Docker compose

sudo apt-get install -y libffi-dev libssl-dev
sudo apt-get install -y python3 python3-pip
sudo apt-get remove python-configparser

sudo pip3 install docker-compose

this is taken from here https://dev.to/rohansawant/installing-docker-and-docker-compose-on-the-raspberry-pi-in-5-simple-steps-3mgl

we have to do it this way, cause the official docs only list a download from the ubuntu repos via automated plugging of arch and os names via command like uname -s and uname -m, which on a PI give a combination that does not exist for docker-compose, so we need to go old school to install it.
