Install Git and Docker in Node VM

^{The following instructions have been taken from: Install Docker Engine on Ubununtu}

Set up the repository

1. Update the apt package index and install packages to allow apt to use a repository over HTTPS:

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

2. Add Docker’s official GPG key:

    curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo \
    gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
   

3. Use the following command to set up the stable repository.

    echo \
    "deb [arch=$(dpkg --print-architecture) \
    signed-by=/usr/share/keyrings/docker-archive-keyring.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

1. Update the apt package index, and install the latest version of Docker Engine, containerd, and Docker Compose:

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

2. Allow the current user to run docker without sudo:

    sudo usermod $LOGNAME --append --groups docker
   

3. Verify that Docker Engine is installed correctly by running the hello-world image.

    docker run --rm hello-world
   

4. Cleanup

    docker image rm -f hello-world
