Docker

Note: docker-compose executable is required, even though recent versions of Docker contain compose natively

Verify docker-compose is installed locally

docker-compose version 2.2.2 or greater is required:

$ docker-compose -v
Docker Compose version v2.2.2

Install/Upgrade docker-compose

If the command is not found, or the version is less than 2.2.2, run the following to install the latest to /usr/local/bin/docker-compose

#You will need to have jq installed, or this snippet won't run.
VERSION=$(curl --silent https://api.github.com/repos/docker/compose/releases/latest | jq .name -r)
DESTINATION=/usr/local/bin/docker-compose
sudo curl -L https://github.com/docker/compose/releases/download/${VERSION}/docker-compose-$(uname -s)-$(uname -m) -o $DESTINATION
sudo chmod 755 $DESTINATION

Security note on docker

The Docker daemon always runs as the root user so you will need root privileges to interact with it.

The script manage.sh uses docker, so to avoid the requirement of needing to run the script with root privileges it is prefered to be able to manage Docker as a non-root user by following these steps.

This will avoid the need of running the script with root privileges for all operations except the removal of data.

Debian based install

Copy/paste the following should work to get docker and other requirements setup on a Debian based host

sudo apt-get update && sudo apt-get install -y git jq sed curl
sudo apt remove docker-desktop
rm -r $HOME/.docker/desktop
sudo rm /usr/local/bin/com.docker.cli
sudo apt purge docker-desktop
sudo apt-get update
sudo apt-get install -y ca-certificates     curl     gnupg     lsb-release
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
echo   "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/debian \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update && sudo apt-get install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin
sudo groupadd docker
sudo usermod -aG docker $USER
VERSION=$(curl --silent https://api.github.com/repos/docker/compose/releases/latest | jq .name -r)
DESTINATION=/usr/local/bin/docker-compose
sudo curl -L https://github.com/docker/compose/releases/download/${VERSION}/docker-compose-$(uname -s)-$(uname -m) -o $DESTINATION
sudo chmod 755 $DESTINATION
