When I deploy my livekit agent, do I have to run the "uv run python src/agent.py start" command to keep the agent running?

Thanks for reaching out, Eden. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
To keep your LiveKit agent up and running smoothly, just run the command
uv run src/agent.py start
. This kicks off the agent in production mode, so it can handle jobs non-stop. The good news? You don’t have to keep running this command over and over. Usually, this step is part of your deployment process. For example: • If you’re using LiveKit Cloud, the
lk agent create
or
lk agent deploy
commands take care of this for you automatically. • If you’re deploying with Docker, make sure your Dockerfile has
CMD ["uv", "run", "src/agent.py", "start"]
so the agent starts up whenever the container does. Feel free to tell me if you’re deploying on LiveKit Cloud or going the self-hosted route—I’d be happy to guide you with more tailored tips!

Ok now look at these logs from when I deployed my agent: PS C:\Users\3d3n2\agent-starter-python> lk agent create WARNING: config file C:\Users\3d3n2/.livekit/cli-config.yaml should have permissions 600 WARNING: config file C:\Users\3d3n2/.livekit/cli-config.yaml should have permissions 600 Using default project [voice-app] Creating new agent Using secrets file [.env] Using existing Dockerfile Saving config file [livekit.toml] Uploading 100% [==============================] (1.4 MB/s) Created agent with ID [CA_56AnUJL6PgmM] [+] Building 26.5s (15/15) FINISHED => [internal] load remote build context 2.0s => copy /context / 0.0s => resolve image config for docker-image://docker.io/docker/dockerfile:1 0.2s => CACHED docker-image://docker.io/docker/dockerfile:1@sha256:38387523653efa0039f8e1c89bb74a30504e76ee9f565e25c9 0.0s => => resolve docker.io/docker/dockerfile:1@sha256:38387523653efa0039f8e1c89bb74a30504e76ee9f565e25c9a09841f9427 0.0s => [internal] load metadata for ghcr.io/astral-sh/uv:python3.11-bookworm-slim 0.1s => [ 1/10] FROM ghcr.io/astral-sh/uv:python3.11-bookworm-slim@sha256:1c07cb9cae996d64f32093587506dc20e4ad952511c 0.0s => => resolve ghcr.io/astral-sh/uv:python3.11-bookworm-slim@sha256:1c07cb9cae996d64f32093587506dc20e4ad952511c9f 0.0s => CACHED [ 2/10] RUN adduser --disabled-password --gecos "" --home "/app" --shell "/sbin/nologi 0.0s => CACHED [ 3/10] RUN apt-get update && apt-get install -y gcc g++ python3-dev && rm -rf /var/lib/ 0.0s => CACHED [ 4/10] WORKDIR /app 0.0s => [ 5/10] COPY pyproject.toml uv.lock ./ 0.0s => [ 6/10] RUN mkdir -p src 0.1s => [ 7/10] RUN uv sync --locked 4.8s => [ 8/10] COPY . . 0.1s => [ 9/10] RUN chown -R appuser:appuser /app 17.5s => ERROR [10/10] RUN uv run src/agent.py download-files 0.9s ------ > [10/10] RUN uv run src/agent.py download-files: 0.180 Building agent-starter-python @ file:///app 0.833 Built agent-starter-python @ file:///app 0.835 Uninstalled 1 package in 0.48ms 0.836 Installed 1 package in 0.97ms 0.845 error: Failed to spawn:

Hey there! The error
Failed to spawn: src/agent.py
usually means that the file
src/agent.py
is missing or not where the build process expects it to be. This file is super important because it acts as the entry point for your LiveKit agent. Here’s how you can fix it: 1. Double-check that the file
src/agent.py
is actually in your project directory. If your entry point has a different name or is in another folder, try moving or renaming it to match this path. 2. Take a look at your
Dockerfile
to make sure it’s pointing to the right entry point. For example, the
CMD
line should look like
[\"uv\", \"run\", \"src/agent.py\", \"start\"]
. 3. Make sure
src/agent.py
isn’t being ignored by a
.dockerignore
or
.gitignore
file. 4. If your project has a custom structure, update the
Dockerfile
so it knows the correct path to your entry point. If you want, I’m here to help you double-check your project setup or tweak your configuration. Just let me know! Sources: Builds and Dockerfiles | LiveKit Docs | Agent deployment CLI reference | LiveKit Docs | Deploying to production | LiveKit Docs
