Your target (Docker, Kubernetes, AWS, etc.)?

When you run your Go application on your local machine, it will use the environment variables from both .env and .env.go.local files. The values from .env.go.local will override those in .env , so your application will use the local database instance with the specified credentials. .env.go.local

import ( "log" "os"

The common solution is to ignore .env in git and share a .env.example . But then everyone overwrites each other’s local overrides when pulling, or worse—they accidentally commit real secrets.

: Prevents sensitive data like API keys, local database passwords, or private tokens from being pushed to a shared repository. port := os

: It is used to store machine-specific values like local database credentials or API keys that should not be shared with other developers .

Similarly, packages like github.com/jpfuentes2/go-env automatically load .env.local files whenever a default .env file is loaded, specifically for . This gives developers a clean, predictable way to maintain environment-specific configurations without cluttering the shared codebase.
