How to fix environment variables not working while running from system-d service in Go

I am using os.Getenv("APP_PATH") to read from the system environment variables and it works fine when running the build of the application normally. But I need to run this Go program as a service which I have done using systemd in which case it cannot read the environment variables. Is there any way of resolving this?

Solution

  • You can follow along from here to make the use of the environment variables. The way I am using to implement environment variables in my project is GODOTENV go library. It is very easy to implement and platform independent.

    Simply run

    err = godotenv.Load(filepath.Join(path_dir, ".env"))

    and you are done. Now you can use you code os.Getenv("APP_PATH") to read the keys from your .env file and it works perfectly fine with systemd service.
