How to Get the Process ID (PID) in Go

Go provides a simple way to access the current process ID.

The Code

import "os"
pid := os.Getpid()

Go in 2026

In 2026, Go 1.26+ is the standard. The os package provides Getpid() for the current process and Getppid() for the parent process. In cloud-native applications running in Kubernetes, the PID is often less important than the Pod UID or Container ID, which are typically exposed via environment variables or the Downward API.
