CFPB Mac setup scripts

Configurations and scripts for setting up a new developer Mac.

Automated software setup

The provision_tools.sh script installs a standard developer environment on new Mac computers, with the goal of making the machine ready to set up cfgov-refresh for local development. This includes, but is not limited to:

• Homebrew
• Up-to-date or cfgov-refresh-specific versions of several core developer tools:
  • Git (replacing Apple Git)
  • git-secrets hooks for ensuring you don't accidentally commit bad stuff
  • pyenv and pyenv-virtualenvwrapper with Python 3.6.9
  • pipx for running isolated Python applications
    • IMPORTANT: Downgrading Docker Desktop via pipx for use with cf-gov refresh
  • nvm with the latest LTS release of Node
  • Yarn with the following installed globally:
    • yo
    • generator-cf
    • generator-node
    • snyk
• Minimal dotfiles with the necessary bits for all of the above to work as expected

Running the script

1. Run the following command from the root of this repository to initiate the installation: ./provision_tools.sh.
2. After the script completes, run source ~/.bashrc to apply the changes to your current terminal session, or just close the session and open a new one.

Backups

• If any dotfiles (~/.bash_profile, ~/.bashrc, etc.) would be overwritten, they will be backed up to ~/<filename>_<date>.
• If you have anything in your ~/.git-templates/ folder and your global .gitconfig has init.templateDir value is set to that location, your files will be left in place and the init.templateDir will be changed to ~/.git-templates/git-secrets/.

GitHub/SSH setup

The github_setup.sh script has two functions:

1. Ensure the ~/.gitconfig file in your home directory has a name and email address configured so that you get credit for your commits.
2. Create an SSH key (if it doesn't already exist) for integration with GitHub.com and CFPB's GitHub Enterprise instance.
   • If generating an SSH key, you will be prompted to create a password for the key.

After the script completes, you will be provided with a "public key" and the following instructions for applying the key to your two GitHub accounts:

1. Log into your GitHub accounts and paste this public key in the GitHub Settings website
2. Directions for adding keys

The script is safe to run even if you have already configured your .gitconfig and/or SSH key. In this case, the tool will simply output your existing details for your review.

Running the script

Run the following command from the root of this repository: ./github_setup.sh.

Automated github_setup.sh execution at login

This section is intended for CFPB Mac Engineering's automation of the github_setup.sh script on new Macs.

1. Place the file github_setup.sh at the location /usr/local/bin/github_setup.sh.
   • Make sure the file is world executable: chmod +x /usr/local/bin/github_setup.sh.
2. Place the file org.cfpb.github_setup.plist at the location /Users/<username>/Library/LaunchAgents/org.cfpb.github_setup.plist for the user(s) on the computer.
   • This will spawn the github_setup.sh script when the user logs on.
   • Once the user has completed the process, the plist will be disabled to stop future login execution.
