Goals

Provide fully automated Manjaro with i3 development environment that is easy to setup and maintain.

Why Manjaro with i3?

Manjaro provides a very elegant wizard for installing Arch Linux WITH i3-gaps (required) which aligns with the goals of this repository.

Why Ansible?

Ansible replicates what we would do to setup a development environment pretty well. There are many automation solutions out there - we happen to enjoy using Ansible.

Requirements

Operating System

This Ansible playbook only supports Manjaro with i3 distribution. This is by design to provide a consistent development expierence across hosts.

• Download Manjaro with i3
• Install OS

System Upgrade

Verify your Manjaro with i3 installation has all latest packages installed before running the playbook.

sudo pacman -Syu

NOTE: This will take some time.

Setup

values.yaml

The values.yaml file allows you to personalize your setup to your needs. Create a file located at ~/.config/dotfiles/values.yaml and include your desired settings.

cd $HOME && mkdir -p .config/dotfiles && vim .config/dotfiles/values.yaml

Below is a list of all available values. Not all are required but incorrect values will break the playbook if not properly set.

Name	Type	Required
git_user_email	string	yes
git_user_name	string	yes
exclude_roles	array (see group_vars/all)	no
kubectl_config	dict (see Kubernetes below)	no
kubectl_config_active	string (see Kubernetes below)	no
neovim_version	string (branch, tag or SHA)	no
nitrogen_background	string (see roles/nitrogen/files)	no
nodejs_npmrc_config	string (see NodeJS below)	no
ssh_key	dict (see SSH Keys below)	no
system_host	dict (see System Hosts below)	no
zsh_public	dict (see Environment below)	no
zsh_private	dict (see Environment below)	no

Environment

Manage environment variables by configuring the zsh_public and zsh_private values in values.yaml. See both values usecase below.

zsh_public

The zsh_public value allows you to include a dictionary of generic and unsecure key-value pairs that will be stored in a ~/.zsh_public.

---
zsh_public:
  MY_ENV_VAR: something

zsh_private

The zsh_private value allows you to include a dictionary of secure key-value pairs that will be stored in a ~/.zsh_private.

---
zsh_private:
  MY_ENV_VAR_SECRET: !vault |
    $ANSIBLE_VAULT;1.1;AES256

vault-password.txt

The vault-password.txt file allows you to encrypt values with Ansible vault and store them securely in source control. Create a file located at ~/.config/dotfiles/vault-password.txt with a secure password in it.

vim .config/dotfiles/vault-password.yaml

To then encrypt values with your vault password use the following:

$ ansible-vault encrypt_string --vault-password-file $HOME/.config/dotfiles/vault-password.txt "mynewsecret" --name "MY_SECRET_VAR"
$ cat myfile.conf | ansible-vault encrypt_string --vault-password-file $HOME/.config/dotfiles/vault-password.txt --stdin-name "myfile"

NOTE: This file will automatically be detected by the playbook when running dotfiles command to decrypt values. Read more on Ansible Vault here.

Usage

Install

This playbook includes a custom shell script located at bin/dotfiles. This script is added to your $PATH after installation and can be run multiple times while making sure any Ansible dependencies are installed and updated.

This shell script is also used to initialize your environment after installing Manjaro with i3, performing a full system upgrade and creating your ~/.config/dotfiles/values.yaml configuration file as mentioned above.

NOTE: You must follow required steps before running this command or things may become unusable until fixed.

$ bash -c "$(curl -fsSL https://raw.githubusercontent.com/ALT-F4-LLC/dotfiles/main/bin/dotfiles)"

Update

This repository is continuously updated with new features and settings which become available to you when updating.

To update your environment run the dotfiles command in your shell:

$ dotfiles

This will handle the following tasks:

• Verify Ansible is up-to-date
• Generate SSH keys and add to ~/.ssh/authorized_keys
• Clone this repository locally to ~/.dotfiles
• Verify any ansible-galaxy plugins are updated
• Run this playbook with the values in ~/.config/dotfiles/values.yaml

Known Issues

Neovim Updates

Sometimes the cloning task in neovim role fails due to conflicts with the repository history. The easiest solution is to delete the repository at ~/Development/repository/github.com/neovim/neovim and let the playbook clone it again.
