new_droplet.md

1. Log on with ssh root@<public ip>.
2. Add new user with adduser <username>.
3. Give that new user sudo permissions with usermod -aG sudo <username>
4. Copy ssh keys from root user to new user

   mkdir /home/<username>/.ssh
   cp ~/.ssh/authorized_keys /home/<username>/.ssh/
   chown <username> /home/<username>/.ssh/authorized_keys
   

5. Log out and log on with that new user ssh <username>@<public ip>
6. Update and install packages

   sudo apt update
   sudo apt upgrade -y
   
   sudo apt install -y zsh make
   git clone https://github.com/kylebarron/dotfiles.git /tmp/dotfiles
   git clone --depth=1 git://github.com/robbyrussell/oh-my-zsh.git ~/.oh-my-zsh
   git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions
   git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting
   cp /tmp/dotfiles/zsh/materialshell.zsh-theme ~/.oh-my-zsh/themes/
   cp /tmp/dotfiles/zsh/zshrc_desktop ~/.zshrc
   
   wget https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh -O /tmp/miniconda3.sh
   bash /tmp/miniconda3.sh -b -p ~/local/miniconda3
   export PATH=$HOME/local/miniconda3/bin:$PATH
   
   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"
   sudo apt-get update
   sudo apt-get install -y docker-ce docker-ce-cli containerd.io docker-compose
   
   link="$(curl -s https://api.github.com/repos/zyedidia/micro/releases/latest | grep 'browser_download_url' | grep 'linux64' | cut -d '"' -f 4)"
   wget $link -O /tmp/micro.tar.gz
   mkdir /tmp/micro
   tar -xzvf /tmp/micro.tar.gz -C /tmp/micro --strip-components 1
   
   mkdir -p ~/local/bin
   mv /tmp/micro/micro ~/local/bin/
   
   mkdir -p ~/.config/micro
   cp /tmp/dotfiles/micro/* ~/.config/micro/
   
   

7. Set ZSH as default shell chsh -s $(which zsh). (Then log out and back in to take effect).
