Envault

A simple CLI tool to run a process with secrets from AWS Secrets Manager.

About

Envault focuses on integrating AWS Secrets Manager in your application with ease without having to write a single line of code in your source files. Simply run your commands with the Envault CLI and the secrets will be injected in that process.

Usage

1. Install Envault:

curl -sf https://raw.githubusercontent.com/pratishshr/envault/master/install.sh | sudo sh

Note: If your architecture is not supported, clone this repo and run go build to generate a binary. Then, simply place the binary in your local bin.

2. Verify Installation:

envault

3. AWS Credentials

Before using envault, you have to provide your AWS credentials. This allows envault to fetch secrets from the AWS Secrets Manager. Also, make sure you have the correct access for your credentials.

Simply create ~/.aws/credentials file for storing AWS credentials.
Example:

[example-profile]
aws_access_key_id = xxxxxx
aws_secret_access_key = xxxxxx

To know more about AWS configurations, view Configuring the AWS CLI

4. Setup

Go to your project directory and run setup command to initiate the setup process.

envault setup

• Choose your AWS profile that was setup earlier.
  
• Choose the AWS Region where your secrets are kept.
• You can also add a deployment environment associated with the secret name. You may add any number of environment you want.
• Set a default env

 Example:

 AWS profile: default
 Region: US West (Oregon)
 Add an environment (eg. dev): dev
 Secret Name: api/dev
 Add an environment (eg. dev): uat
 Secret Name: api/uat

envault.json file will be created in your project directory like below.

{
  "profile": "default",
  "region": "us-west-2",
  "environments": {
    "dev": "api/dev",
    "uat": "api/uat"
  },
  "defaultEnv": "dev"
}

If you do not want a project-specific config file, you can skip the above step.

5. List secrets

envault list -e dev

envault list -e uat

Here dev and uat are the environments you specified in envault.json.

If you have not setup a envault.json file, you can still pass --secret or -s flag with the secrets path. This will use the default profile from your ~/.aws/credentials file.

envault list --secret=api/dev

envault list --secret=api/uat

6. Run with secrets

envault run 'yarn build' -e dev

This will inject the secrets from dev to the yarn build process.

Similarly, if you have not setup a envault.json file, you can still pass --secret or -s flag with the secrets path. This will use the default profile from your ~/.aws/credentials file.

envault run 'yarn build' --secret=api/dev

7. Usage with CI/CD:

Instead of setting up a ~/.aws/credentials file. You can also use the following environment variables to set up your AWS credentials.

8. Using custom .env files

If you want to inject environment keys from a file instead of using AWS Secrets Manager. You can use the-ef flag.

envault run 'envault run 'go run main.go' -ef env/staging.env
