Hello Spencer,
When you're running a Lambda function in a Docker container and trying to connect to another service (like Oathkeeper) within the same container, using localhost
should work, but only if the service you're trying to connect to is running and listening on the specified port. The error connection refused
suggests that nothing is listening on port 4456 when the Lambda function tries to make the connection.
Items to check:
-
Service Startup: Make sure that Oathkeeper starts successfully before the Lambda function tries to connect to it. You can add logging to the init process to confirm that the service has started.
-
Container Networking: If
localhost
doesn't work, it could be due to how networking is handled in Docker. In some Docker configurations, the services might not be reachable throughlocalhost
. Instead, they could be available through the container's IP address. -
Port Exposing: Ensure that the port 4456 is exposed and not blocked by any Docker networking configurations or by the host.
-
Health Check: Implement a health check that ensures Oathkeeper is fully initialized and ready to accept connections before your Lambda function tries to connect.
-
Docker Compose: If you're using Docker Compose, ensure that your service dependencies are correctly defined, so the services start in the right order.
Here's a simple health check to your init function:
func init() { // ... existing code ... // Wait for Oathkeeper to be ready before proceeding for i := 0; i < maxRetries; i++ { conn, err := net.Dial("tcp", "localhost:4456") if err == nil { conn.Close() break } fmt.Printf("Waiting for Oathkeeper to be ready: %v\n", err) time.Sleep(retryInterval) } }
Lastly, if oathkeeper
runs in a separate container, localhost
won't work. You'll need to use the Docker networking features to connect containers. This often involves using the service names defined in docker-compose.yml
as the hostnames.
Hope this helps!
