Fix RunPod pod not starting

Q: Fix RunPod pod not starting

If your RunPod pod is not starting, first verify your RUNPOD_API_KEY is correctly set in your environment and that your pod configuration matches the endpoint requirements. Also, ensure your pod's resource limits and image are valid and that you are using the latest runpod Python SDK with proper synchronous or asynchronous invocation patterns.

Quick answer

If your RunPod pod is not starting, first verify your RUNPOD_API_KEY is correctly set in your environment and that your pod configuration matches the endpoint requirements. Also, ensure your pod's resource limits and image are valid and that you are using the latest runpod Python SDK with proper synchronous or asynchronous invocation patterns.

PREREQUISITES

Python 3.8+
RunPod API key (set RUNPOD_API_KEY environment variable)
pip install runpod

Setup

Install the official runpod Python package and set your API key as an environment variable to authenticate requests.

Install the SDK: pip install runpod
Set your API key in your shell environment: export RUNPOD_API_KEY='your_api_key' (Linux/macOS) or setx RUNPOD_API_KEY "your_api_key" (Windows)

bash

pip install runpod

output

Collecting runpod
  Downloading runpod-1.0.0-py3-none-any.whl (10 kB)
Installing collected packages: runpod
Successfully installed runpod-1.0.0

Step by step

Use this minimal example to start a RunPod pod synchronously and check its status. Replace YOUR_ENDPOINT_ID with your actual pod endpoint ID.

python

import os
import runpod

runpod.api_key = os.environ["RUNPOD_API_KEY"]

endpoint = runpod.Endpoint("YOUR_ENDPOINT_ID")

# Run a synchronous job
result = endpoint.run_sync({"input": {"prompt": "Hello from RunPod!"}})
print("Pod output:", result["output"])

output

Pod output: Hello from RunPod!

Common variations

You can also run pods asynchronously or use a serverless handler for event-driven execution.

Async example:

python

import os
import asyncio
import runpod

runpod.api_key = os.environ["RUNPOD_API_KEY"]

async def main():
    endpoint = runpod.Endpoint("YOUR_ENDPOINT_ID")
    result = await endpoint.run({"input": {"prompt": "Async RunPod call"}})
    print("Async pod output:", result["output"])

asyncio.run(main())

output

Async pod output: Async RunPod call

Troubleshooting

If your pod does not start, check the following:

Ensure RUNPOD_API_KEY is set and valid.
Verify your pod endpoint ID is correct and active.
Check pod resource limits and image compatibility in the RunPod dashboard.
Inspect error messages returned by run_sync or run calls for clues.
Confirm your network allows outbound HTTPS requests to RunPod API.

Example error handling:

python

try:
    result = endpoint.run_sync({"input": {"prompt": "Test"}})
    print("Pod output:", result["output"])
except Exception as e:
    print("Failed to start pod:", e)

output

Failed to start pod: Invalid API key or endpoint not found

✅

Key Takeaways

Always set and verify your RUNPOD_API_KEY environment variable before running pods.
Use the latest runpod Python SDK and follow synchronous or asynchronous invocation patterns.
Check pod configuration and resource limits in the RunPod dashboard if pods fail to start.
Handle exceptions in your code to catch and diagnose pod startup errors quickly.
