ubuntu-setup

This is my personal repo I use for setting up a new Ubuntu machine. I use it for both daily drivers and throwaway VMs (I like to SSH into the VM and play around in it, and when I do that, I like having nice stuff like zsh and rg)

Setting up a new Ubuntu machine

When setting up Ubuntu, I created the dmitry user.

On the machine, install the OpenSSH server.

sudo apt update
sudo apt install -y openssh-server

At this point, password authentication will be enabled, which is what I want because this way I can easily SSH in and edit authorized_keys on the new machine.

Now, generate a new ssh key using 1Password. Add the public key to authorized_keys on the new machine.
Now, create an Ansible user. On the new machine:

sudo adduser ansible
sudo usermod -aG sudo ansible

sudo -u ansible mkdir /home/ansible/.ssh
sudo -u ansible chmod 0700 /home/ansible/.ssh
cat /home/dmitry/.ssh/authorized_keys | sudo -u ansible tee /home/ansible/.ssh/authorized_keys
sudo chown ansible:ansible /home/ansible/.ssh/authorized_keys

ansible.cfg reads the become_pass from an environment variable (ANSIBLE_SUDO_PASS) which means you can run Ansible without typing in a password, yet without compromising security, like so: ANSIBLE_SUDO_PASS=$(op item get ansible --fields label=password) ansible-playbook ...

One thing you’ll need to do manually is authenticate GH CLI.

gh auth login
# On another computer, visit https://github.com/login/device/
gh auth setup-git

Now, you can run your Ansible magic against this machine.
On the new machine, install oh-my-zsh. I couldn’t figure out how to do it using Ansible.

sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

Also, you will need to install fnm manually. (This is node version manager, so you might not need it)

curl -fsSL https://fnm.vercel.app/install | bash

Finally, you can use pyenv to setup Python.

pyenv install 3.11.3
pyenv global 3.11.3

Install 1Password. Out of laziness, I did these steps manually, but they should be pretty easy to turn into an Ansible playbook. https://support.1password.com/install-linux/#debian-or-ubuntu
I also installed Tailscale manually. This would be easy to convert into an Ansible playbook as well.
Install pyenv-virtualenv git clone https://github.com/pyenv/pyenv-virtualenv.git $(pyenv root)/plugins/pyenv-virtualenv
Install bpftrace using ansible/files/install_bpftrace.sh
Install VScode by downloading the .deb (yes, also not doing it via ansible out of laziness)
Install Anki (instructions)
Manually: change paste shortcut in terminal from (seriously, WHO finds this easy to type?) to (TODO: somehow do this globally)
Install rust: curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
