How to fix environment variables not working while running from system-d service in Go
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
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?

Add your service definition file to the question, otherwise we can only guess.

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.

It depends on how you're running your systemd service. Systemd provide a bunch of derictive you should use:
[Unit]
Description=My service
After=network.target
[Service]
Type=simple
User=user
Group=user
EnvironmentFile=/home/user/env_file
ExecStart=/bin/bash -c -l '/home/user/go_program'
# ... other directive goes here
[Install]
WantedBy=multi-user.target
EnvironmentFile- the file with ENV variables, that file will be loaded for you by systemd.User,Group- under which user and group the program should run.
ExecStart=/bin/bash -c -l '/home/user/go_program'- the-loptions makes bash act as if it had been invoked as a login shell, so the variable in your.bash_profilewill be loaded(seeUserandGroupsection).
