Chapter I: A Secret to Everybody

First, you'll need to create an account with the secrets management platform Doppler. Once you're signed up, create a project for 3515.games. By default, your project will have three environments: dev, stg. and prd — short for development, staging, and production, respectively. We'll come back to all this later.

For now, go ahead and install the Doppler CLI.

macOS Windows Debian / Ubuntu Fedora / Red Hat / CentOS Shell Script

Install Homebrew, then:

brew install gnupg dopplerhq/cli/doppler

Install Scoop, then:

scoop bucket add doppler https://github.com/DopplerHQ/scoop-doppler.git
scoop install doppler

sudo apt-get update && sudo apt-get install -y apt-transport-https ca-certificates curl gnupg
curl -sLf --retry 3 --tlsv1.2 --proto "=https" 'https://packages.doppler.com/public/cli/gpg.DE2A7741A397C129.key' | sudo apt-key add -
echo "deb https://packages.doppler.com/public/cli/deb/debian any-version main" | sudo tee /etc/apt/sources.list.d/doppler-cli.list
sudo apt-get update && sudo apt-get install doppler

sudo rpm --import 'https://packages.doppler.com/public/cli/gpg.DE2A7741A397C129.key'
curl -sLf --retry 3 --tlsv1.2 --proto "=https" 'https://packages.doppler.com/public/cli/config.rpm.txt' | sudo tee /etc/yum.repos.d/doppler-cli.repo
sudo yum update && sudo yum install doppler

You should generally prefer one of the other options before resorting to this one. This doesn't work on Windows. (1)

1. It may work on WSL, but we're not covering that here.

Install curl and GnuPG, then:

(curl -Ls --tlsv1.2 --proto "=https" --retry 3 https://cli.doppler.com/install.sh || wget -t 3 -qO- https://cli.doppler.com/install.sh) | sudo sh

Verify the CLI was installed by checking it's version:

doppler --version

Then connect the CLI to your Doppler account:

doppler login

Cool. On to the next step.
