CAPI Workstation Helpers 🐋

Hello there! This repo is intended to help with development work on CAPI projects.

Directory Overview

Description of the folders in this project:

Folder	Description
assets	random static files
bash-it	all the bash-it stuff, only bash-it stuff
helpers	random helper files
lib	scripts that could be sourced into your shell
bin	scripts that can be added to your $PATH
install-scripts	executable scripts that install a thing or two

Why is lib separate from bash-it? Not everyone uses bash-it, so lib is similar to scripts, giving people a way to manually load the things they care about in.

Minimal Install

One may manually (and minimally) load in capi-workspace content by including the following in their ~/.zshrc (or equivalent):

source <(cat $HOME/workspace/capi-workspace/lib/*) > /dev/null
path+=("$HOME/workspace/capi-workspace/bin")

Using the Bosh Lite Pool

As a perk, CAPI approvers get access to a pool of cf-deployment environments, deployed on bosh lites in a CFF-managed IaaS account. These environments are disposable, and are only intended for development use.

Though it is technically possible to use the pool without them, there are a number of convenience scripts provided by capi-workspace that make the pool usable by humans.

Prerequisites

• git
• Clone capi-workspace (this repo)
• Add capi-workspace scripts/functions to your shell (see installation instructions above (or below))
• Clone https://github.com/cloudfoundry/capi-env-pool

Example Pool Dev Workflow

Claim an environment from the pool:

❯ claim_bosh_lite
Claiming 'distaffs'...
Writing out .envrc...
Pushing reservation to capi-env-pool...
Use 'target_bosh distaffs' to set bosh environment variables.

Observe that you successfully claimed the environment:

❯ print_env_info
Rounding up claimed environments...

* ENV *      * CLAIMED BY *  * CLAIMED ON *                  * CLAIMED SINCE *
apologia     Tim Downey      tdowney.hostname                3 weeks ago
distaffs     Greg Cobb       gcobb.hostname                  2 minutes ago
riskier      Greg Cobb       gcobb.hostname                  13 days ago
zoned        Seth Boyles     capi-ws-cc-203                  3 weeks ago

Set bosh environment variables in your shell to "target" that environment:

❯ target_bosh distaffs

Automated Workstation Setup

If you want, there are also some opinionated scripts you can run to set up a new computer for CAPI development. These may be useful if you are dynamically provisioning remote workstations, or something like that.

Dependencies

• MacOS
• pip

Running the Installer

    mkdir -p ~/workspace && cd ~/workspace
    git clone [email protected]:cloudfoundry/capi-workspace.git && cd capi-workspace

You can now either install via ./install.sh or ./install-core.sh.

Or curl the bootstrap script, which will create the workspace directory and clone this repo for you. This is primarily intended for quickly setting up virtual workstations.

bash <(curl -s https://raw.githubusercontent.com/cloudfoundry/capi-workspace/main/bootstrap.sh)

Manual steps (to be automated later)

• Open System Preferences / Users & Groups / / Login Items
  • Add flycut from Applications
  • Add spectacle from Applications
• Log out/Log in
  • This will cause Flycut and Spectacle to run and ask for permissions
• Open up Rubymine manually and enter a License Server
• Install the mine cli shortcut (RubyMine -> Tools -> Create Command-line Launcher...)
• If you are using Goland do the same two previous steps for Goland
• If you have access to the private CAPI backlog, add a secure note called tracker_api_token to LastPass with your Pivotal Tracker API token. This token will be used in scripts such as claim_bosh_lite to pull story titles currently in flight.

Contributing to this repo

• kindly consider when a change is worth making to install-core.sh versus install.sh.
• bash-it We use bash-it to organize and streamline our bash settings. This includes stuff like color schemes, aliases, shell settings, and the shell prompt formatting. Adding "plugins" to custom-bash-it-plugins will cause them to be installed in every new shell.

What this installation does

install-core.sh: intended to be more friendly for developers who don't want this repository to take over their machine. This is intended to be the minimal set of things required for working with a CAPI repository.

• Only installs core utilities, languages, services, and binaries.
• Is NOT responsible for installing & configuring any editors (nvim/vscode/intellij)
• Is NOT responsible for installing tools for improving developer workflows (jq/rg)
• Is NOT responsible for applying any git configuration
• Is NOT responsible for loading in scripts that need to be source'd.
• Is NOT responsible for modifying your $PATH to include script

./install.sh: runs install-core.sh and configures the machine with many more packages/preferences

install.sh or install-core.sh ?

install-core.sh is a subset of install.sh and is intended to be less invasive to the machine, without compromising on provisioning a workstation suitable to working on CAPI projects.

For fresh workstations && full-time CAPI developers, install.sh might make more sense.

For folks working on multiple projects, install-core.sh might make more sense.

For folks with existing workstations & configuration, install-core.sh might make more sense.
