CLI Guide

Learn how to get up and running with the Doppler CLI to inject secrets into your applications.

Installation

The Doppler CLI provides a consistent experience between developing locally and production. It is a lightweight binary that comes provided in a number of package managers, including Docker.

The Doppler CLI is open source can be found on GitHub.

# GnuPG is required for binary signature verification
brew install gnupg

# Using curl
curl -Ls --tlsv1.2 --proto "=https" --retry 3 https://cli.doppler.com/install.sh | sudo sh

# Using wget
wget -t 3 -qO- https://cli.doppler.com/install.sh | sudo sh

# Using brew (not recommended as auto-update is not supported)
brew install dopplerhq/cli/doppler
scoop bucket add doppler https://github.com/DopplerHQ/scoop-doppler.git
scoop install doppler
# Add Doppler's RSA key
wget -q -t3 'https://packages.doppler.com/public/cli/rsa.8004D9FF50437357.key' -O /etc/apk/keys/[email protected]

# Add Doppler's apk repo
echo 'https://packages.doppler.com/public/cli/alpine/any-version/main' | tee -a /etc/apk/repositories

# Install latest Doppler CLI
apk add doppler
# Install pre-reqs
sudo apt-get update && sudo apt-get install -y apt-transport-https ca-certificates curl gnupg

# Add Doppler's GPG key
curl -sLf --retry 3 --tlsv1.2 --proto "=https" 'https://packages.doppler.com/public/cli/gpg.DE2A7741A397C129.key' | sudo apt-key add -

# Add Doppler's apt repo
echo "deb https://packages.doppler.com/public/cli/deb/debian any-version main" | sudo tee /etc/apt/sources.list.d/doppler-cli.list

# Fetch and install latest doppler cli
sudo apt-get update && sudo apt-get install -y doppler
# Add Doppler's GPG key
sudo rpm --import 'https://packages.doppler.com/public/cli/gpg.DE2A7741A397C129.key'

# Add Doppler's yum repo
sudo curl -sLf --retry 3 --tlsv1.2 --proto "=https" 'https://packages.doppler.com/public/cli/config.rpm.txt' > /etc/yum.repos.d/doppler-cli.repo

# Update packages and install latest doppler cli
sudo yum update && sudo yum install doppler
# Does not rely on package managers
# Recommended for ephemeral environments (e.g. CI jobs)
# Supports Linux, BSD, and macOS

# Requires Curl & GnuPG:
#        Alpine: apk add curl gnupg
#   CentOS/RHEL: yum install -y curl gnupg
# Ubuntu/Debian: apt install -y curl gnupg

(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

Now let's verify the Doppler CLI was installed correctly.

doppler --version

Authentication

The Doppler CLI requires an API key for authentication. Access can be granted via the login flow for local development or using a Service Token for production environments as it restricts access to a specific config within a Project.

doppler login
# Service Token can be generated using the CLI or the dashboard

echo 'dp.st.prd.xxxx' | doppler configure set token --scope /

Basic Usage

You can fetch the latest versions of your secrets for your project and selected config using the run command, which injects them as environment variables into the running process from your command or script.

doppler run -- your-command-here
doppler run --command="./configure && ./process-jobs; ./cleanup"

Because Doppler injects secrets as environment variables, it works for any language, framework, platform, and cloud provider.

const secret = process.env["SECRET_NAME"]
secret = os.getenv("SECRET_NAME")
secret = ENV["SECRET_NAME"]
secret := os.Getenv("SECRET_NAME")
String secret = System.getenv().get("SECRET_NAME")
$secret = $_ENV["SECRET_NAME"]
secret = env::var("SECRET_NAME")
var secret: String = System.getenv("SECRET_NAME")
def secret = System.getenv("SECRET_NAME")
char const* secret = getenv("SECRET_NAME");

To run one-off commands using a secret in Doppler, please make sure to escape the secret or use single quotes. You will need to do this to guard against shell parsing the variable before the run command executes.

doppler run --command="echo \$SECRET_NAME"
doppler run --command='echo $SECRET_NAME'
echo $(doppler secrets get SECRET_NAME --plain)

Accessing Secrets

The Doppler CLI has numerous methods for supplying secrets to your application. See our dedicated Accessing Secrets Guide to learn more.

Setting Secrets

The CLI several easy to use options for setting and importing secrets. See our dedicated Setting Secrets Guide to learn more.

Shell Completion

Command completions are installed automatically. If completions are not working for you, add the following to your ~/.bash_profile or similar:

source <(doppler completion 2> /dev/null)

Running aliased commands

Running aliased commands is currently not supported. To use an alias, source your aliases file before executing your app.

doppler run --command="source ~/.bash_aliases && my_aliased_command"

Multiple workplaces

The Doppler CLI supports multiple workplaces by allowing you to scope your login to a specific directory. Any applications inside your chosen directory (and its sub-directories) will automatically use the correct API key. Take a look at our docs on using the CLI with multiple workplaces for more information.

Running an alternative shell

When using the --command flag, the Doppler CLI will determine what shell to use based on the SHELL environment variable. The CLI currently supports sh, bash, zsh, dash, fish, ksh, tcsh, and csh. If you are using an alternative shell, the CLI will fall back to sh. You can manually specify your preferred shell.

# e.g. use zsh2
doppler run -- zsh2 -c "printenv DOPPLER_CONFIG"

Update

The Doppler CLI supports updating itself via the doppler update command. This will automatically download and install the latest version of the CLI.

The CLI will also prompt you to update whenever a new version is released.

🚧

Windows Users

This command is not supported on Windows when installed via Scoop. Instead, we recommend using winget.

Commonly Used Commands

These are some commonly used commands that you'll likely find yourself using pretty regularly. There are more advanced ways to use the CLI, so we recommend exploring the available commands, but this should help jump start your usage!

Assign a directory to a specific config

You can perform an operation that assigns a specific directory (and its subdirectories) to a particular config. This allows you to run commands without specifying the project (-p) and config (-c) flags.

doppler setup

If you like, you can also create a doppler.yaml file that notes which project and config should be set using doppler setup:

setup:
  - project: your-project-name
    config: your-config-name

If you have a monorepo-style project where a variety of subdirectories should map to different Doppler projects, you can handle that as well:

setup:
  - project: backend
    config: dev_personal
    path: backend/
  - project: frontend
    config: dev_personal
    path: frontend/
  - project: worker
    config: dev_personal
    path: worker/

You can then run doppler setup --no-interactive to set this up automatically without an interactive prompt.

Run a command with secrets populated in environment

Populate the environment for a command with the secrets from your config.

doppler run -p PROJECT -c CONFIG -- YOUR_COMMAND_HERE

If you need to reference the secret environment variable in your command string, use this syntax:

doppler run -p PROJECT -c CONFIG --command 'YOUR_COMMAND_HERE --some-flag $SOME_VARIABLE'

Fetch secrets from a config

Print the secrets from a config in the designated format to STDOUT. If you don't use the --no-file flag, then it will save as an encrypted fallback file.

doppler secrets download --no-file --format=json

Fetch CLI token from your local environment

You can fetch the CLI token being used in your local shell (which is set when you do a doppler login) using this command:

doppler configure get token --plain

This can be useful when doing testing with the API or other areas where you need a service token:

curl -H "Authorization: Bearer $(doppler configure get token --plain)" "https://api.doppler.com/v3/...."

Generate an ephemeral service token

If you need to generate a service token that will expire, you can do so via the CLI like this:

doppler configs tokens create your-token-name-here -p PROJECT -c CONFIG --max-age 1m --plain

You can make use of this in scripts or other automation by assigning it to a variable like this:

DOPPLER_TOKEN=$(doppler configs tokens create your-token-name-here -p example-api -c dev --max-age 1m --plain)
doppler run -- YOUR_COMMAND_HERE
