dotenv-vault-kotlin Release

<img src="https://raw.githubusercontent.com/motdotla/dotenv/master/dotenv.svg" alt="dotenv-vault" align="right" width="200" />

Extends the proven & trusted foundation of dotenv-kotlin, with .env.vault file support.

The extended standard lets you load encrypted secrets from your .env.vault file in production (and other) environments.

🌱 Install

Add jitpack repository to your build.gradle or build.gradle.kts and require the com.github.dotenv-org:dotenv-vault-kotlin:x.x.x implementation dependency.

// build.gradle
...
repositories {
    ...
    maven { url 'https://jitpack.io' }
}

dependencies {
    ...
    implementation 'com.github.dotenv-org:dotenv-vault-kotlin:0.0.2'
}

or

// build.gradle.kts
...
repositories {
    ...
    maven { url = uri("https://jitpack.io") }
}

dependencies {
    ...
    implementation("com.github.dotenv-org:dotenv-vault-kotlin:0.0.2")
}

🏗️ Usage

Development usage works just like dotenv-kotlin.

Add your application configuration to your .env file in the root of your project:

S3_BUCKET=YOURS3BUCKET
SECRET_KEY=YOURSECRETKEYGOESHERE

As early as possible in your application code, load .env:

Kotlin

import org.dotenv.vault.dotenvVault

val dotenv = dotenvVault()
dotenv["S3_BUCKET"]

Android

Note: The above configuration is required because dot files in /assets do not appear to resolve on Android. (Seeking recommendations from the Android community on how dotenv-kotlin configuration should work in order to provide the best experience for Android developers)

Alternatively, if you are using Provider android.resource you may specify

 directory = "android.resource://com.example.myapp/raw"
Add Dotenv Key

Add DOTENV_KEY to your build system environment variables.

Add key into your build config in your build.grade inside the android->built types

android {
    buildTypes {
        debug {
            buildConfigField "String", "DOTENV_KEY", System.getenv("DOTENV_KEY") ?: ""    
        }
    } 
}

🚀 Deploying

Install dotenv-vault.

See install instructions at https://www.dotenv.org/install

Then encrypt your environment variables by doing:

$ dotenv-vault local build

This will create an encrypted .env.vault file along with a .env.keys file containing the encryption keys.

Set the DOTENV_KEY environment variable by copying and pasting the key value from the .env.keys file onto your server or cloud provider. For example in heroku:

$ heroku config:set DOTENV_KEY=<key string from .env.keys>

Commit your .env.vault file safely to code and deploy. Your .env.vault fill be decrypted on boot, its environment variables injected, and your app work as expected.

🌴 Manage Multiple Environments

You have two options for managing multiple environments - locally managed or vault managed - both use <a href="https://github.com/dotenv-org/dotenv-vault">dotenv-vault</a>.

Locally managed never makes a remote API call. It is completely managed on your machine. Vault managed adds conveniences like backing up your .env file, secure sharing across your team, access permissions, and version history. Choose what works best for you.

💻 Locally Managed

Create a .env.production file in the root of your project and put your production values there.

# .env.production
S3_BUCKET="PRODUCTION_S3BUCKET"
SECRET_KEY="PRODUCTION_SECRETKEYGOESHERE"

Rebuild your .env.vault file.

$ dotenv-vault local build

Check your .env.keys file. There is a production DOTENV_KEY that coincides with the additional DOTENV_VAULT_PRODUCTION cipher in your .env.vault file.

Set the production DOTENV_KEY on your server, recommit your .env.vault file to code, and deploy. That's it!

🔐 Vault Managed

Sync your .env file. Run the push command and follow the instructions. learn more

$ dotenv-vault push

Manage multiple environments with the included UI. learn more

$ dotenv-vault open

Build your .env.vault file with multiple environments.

$ dotenv-vault build

Access your DOTENV_KEY.

$ dotenv-vault keys

Set the production DOTENV_KEY on your server, recommit your .env.vault file to code, and deploy. That's it!

📚 Examples

❓ FAQ

What happens if DOTENV_KEY is not set?

Dotenv Vault gracefully falls back to dotenv-kotlin when DOTENV_KEY is not set. This is the default for development so that you can focus on editing your .env file and save the build command until you are ready to deploy those environment variables changes.

Should I commit my .env file?

No. We strongly recommend against committing your .env file to version control. It should only include environment-specific values such as database passwords or API keys. Your production database should have a different password than your development database.

Should I commit my .env.vault file?

Yes. It is safe and recommended to do so. It contains your encrypted envs, and your vault identifier.

Can I share the DOTENV_KEY?

No. It is the key that unlocks your encrypted environment variables. Be very careful who you share this key with. Do not let it leak.
