Google Cloud Project Manager

gpm is an engineer productivity CLI for switching fast between multiple Google Cloud Platform (GCP) projects ⚡️


✨ Features

  • Allows fast switching between GCP projects.
  • Takes care of your Application Default Credentials (ADC) so that you don't have to gather them after switching a project.
  • Support for defining your GCP project directly in your repository.

🏃🏽‍♀️ Motivation

When you're deploying projects to the Google Cloud Platform, chances are high that you have gcloud configured locally. Although, gcloud allows the configuration of multiple projects and accounts, it doesn't support multiple Application Default Credentials (ADC) out of the box. ADCs are useful if you develop on your local machine, but communicate with GCP services directly in the cloud. For example, all official Google Cloud libraries for Node.js are using ADCs so that no further service account configuration is necessary.

gpm faces this problem by adding your local configured gcloud project to an own repository, including your configured ADCs. With this in place, it is possible to switch between projects quite easily without executing gcloud auth application-default login over and over again.

📦 Installation

npm i -g @openformation/gpm

Alternatively, when you're using npm in your projects, you could install gpm as a devDependency and execute it in your npm run scripts accordingly:

npm i -D @openformation/gpm

🔧 Usage

Adding existing projects

Due to the fact that you will have a configured Google Cloud project in place, we add this to the gpm repository right now:

gpm register

Adds your currently configured project to the repository. Performing a gpm info will show you that this was successful.

Adding new projects

When you are using gpm and want to add another gcloud project, you have to deactivate the project you're currently using with gpm, perform the gcloud initialization and register the project in the gpm repository afterwards:

gpm deactivate

gcloud init

gpm register

Activating a project

Via the CLI

When you want to switch between projects, you have to options: 1.) Selecting it through the gpm CLI or 2.) Using a local .gpmrc which – for example – lives in your source repository. Let's checkout both ways:

gpm activate

This command gives you a list of all gcloud projects that live in the gpm repository. You can select the one you want to use from this list.

Via a configuration file

As described above, the second apporach is via a configuration file (.gpmrc). This file includes the name of the project:

my-fancy-gcloud-project-v1

When executing a gpm use in the directory where this file lives, gpm will determine if the user has this project in her local repository and activates that accordingly.

Automatic activation

We can go even deeper and create a small "bash" function which recognizes if you cd into a directory in which a .gpmrc lives. Whenever this function recognizes the file, it invokes gpm use so that the correct project gets activated.

To make this happen, add this function to your ~/.bashrc or ~/.zshr (depends on which shell you're using):

function cdgpm() {
  cd "$@";

  if [ -f $(pwd)/.gpmrc ]; then
    gpm use
  fi
}

alias cd='cdgpm'
cd $PWD

🎨 Contributing

You don't need to have any fancy prerequisites, just the current LTS release of Node.js

git clone [email protected]:openformation/gpm.git

cd gpm

# Install the correct Node.js version, using `fnm`
fnm use

# Install the dependencies
npm i

Now you are all set up for hacking on the code. Testing a CLI command, is possible via ts-node, for example ...

npx ts-node src/index.ts --version

... will print the version of gpm.

Commitizen

Commitizen friendly

The project is using commitizen for ensuring semantic commit messages. So whenever you perform a git commit an assistant will guide you through the steps of writing semantically correct commit messages.
