how are env vars injected into the lk agent when building for production deployment? i have an env vars checker and im getting that envrionment variables aren't found during run step

Thanks for reaching out, Sebastián. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.

is the Agents framework deploy

I'm glad you're exploring the LiveKit Agents framework! When it comes to injecting environment variables during production deployment, the LiveKit CLI offers two friendly ways to do this: • Inline via

--secrets

flag: You can simply pass comma-separated key-value pairs right in your command line. For example:

lk agent create --secrets OPENAI_API_KEY=sk-xxx,GOOGLE_API_KEY=<http://ya29.xxx|ya29.xxx>

• Via secrets file: If you prefer, you can specify a file containing

KEY=VALUE

pairs (one per line) using the

--secrets-file

option. Common file names like

.env

,

.env.local

, and

.env.production

work perfectly. Just a helpful note: core LiveKit environment variables such as

LIVEKIT_URL

,

LIVEKIT_API_KEY

, and

LIVEKIT_API_SECRET

are taken care of automatically by LiveKit Cloud at runtime, so you don’t need to include them in your secrets file or set them manually. And whenever you need to update your secrets, you can easily do so with the

lk agent update-secrets

command. This will trigger a rolling restart, smoothly applying your changes to new sessions without any hassle. Sources: Agent deployment CLI reference | LiveKit Docs | Secrets management | LiveKit Docs | Builds and Dockerfiles | LiveKit Docs

but why am i getting that there are not found if they are present? when are they actually injected?

I'd love to help you figure out why the environment variables aren't being found. Could you please share a bit more information with me? • What exact error message or behavior are you seeing? • How are you checking if the environment variables are there? For example, are you using logs or any debugging tools? • Are you using the

--secrets

flag or a

--secrets-file

when you deploy? • Are there any particular steps or settings in your deployment process that might influence how environment variables are being injected? With these details, I’ll be better equipped to guide you through a solution!

im using python-dotenv and checking os.getenv

Using

python-dotenv

to inject environment variables in LiveKit is definitely supported, and I’m here to help you get it working smoothly. If you’re finding that

os.getenv()

isn’t picking up your variables, there are a few common things we can check together: • Make sure your

.env

file is actually being loaded by calling

load_dotenv()

early on in your application—ideally before any

os.getenv()

calls happen. • Double-check that your

.env

file exists, is named correctly (it should be

.env

, not something like

.env.local

), and is in the right directory. • Confirm that environment variables aren’t being accessed before

load_dotenv()

runs in your code. To help you get this sorted, here are a few things to verify: •

load_dotenv()

is called at the very start of your application. • Your

.env

file is properly formatted and sitting where your app expects it. • The

.env

file is included in your deployment and hasn’t been accidentally left out. If you’d like, I’m more than happy to walk through these steps with you or help troubleshoot further—just let me know!

when are env vars available in the agent context?

Hi there! I wanted to share some helpful info about environment variables in the LiveKit Agents framework. These variables are available right when the worker process starts, and they play an important role during initialization to set up connections to the LiveKit server and authenticate with external services. When you're deploying to production, these environment variables are usually injected into the container environment at runtime by your deployment platform, like Fly.io or Kubernetes. Here are a couple of examples to guide you: • On Fly.io, you can set secrets using the

fly secrets set

command, and they’ll be ready as environment variables once the worker process kicks off. • In Kubernetes, you define environment variables in your deployment manifest, and they get applied when the pod starts running. Just a friendly reminder to make sure all the necessary environment variables are set and available before the worker process begins, since they’re read during initialization to help establish connections and configure how things run.

and in the LiveKit Agents Framework?

Hi there! When working with the LiveKit Agents Framework, it's important to know that environment variables need to be set up before the agent worker process starts. These variables help your agent connect smoothly to the LiveKit server and authenticate with any third-party services you might be using. To get you started with a minimal setup, here are the key environment variables you'll want to have ready: • `LIVEKIT_URL`: This is the URL of your LiveKit server. • `LIVEKIT_API_KEY`: Your API key for authenticating with LiveKit. • `LIVEKIT_API_SECRET`: The secret that pairs with your API key for authentication. Depending on the plugins or services your agent uses, you might also need to add other variables like

OPENAI_API_KEY

or

DEEPGRAM_API_KEY

. Just a friendly reminder to have these variables set before starting the worker process, as they’re essential for configuring connections and how your agent behaves at runtime.

for debugging purposes, i want to see available environment variables on the livekit agent

I'd be happy to help you debug and view the environment variables on your LiveKit Agent! Here's a simple way to get started: • You can modify your agent's code to log all environment variables right when it starts up. For example, in Python, you might use:

import os
print(os.environ)

• Try to add this logging early in the initialization process, so it captures everything before other parts of your code rely on those variables. • If you have access to the container or runtime environment, another handy option is to run commands like

env

or

printenv

to see all the environment variables listed out. Please feel free to reach out if you'd like any help with adding this to your setup or understanding what the output means. I'm here to support you every step of the way!
