Passing environmental variables to the script ...

[codevin]

Let us say I want to do:

PORT=8080 pm2 start -i 4 app.js

I expect that the environment variable will be available to the script. (And I am not able to receive it.) I am trying to find why I am not able to see that variable.

Before I dig deeper, could you confirm (by updating the documentation) that environmental variables are indeed available?

The entire environment is passed to child scripts. I just tested now and it works

[manast]

It works when using start, but at least for restart command it does not work, it keeps using the same environment as the one available when the app was initially started.
So if I have a script: app.js:

console.log(process.env[NODE_ENV]);

If I do:

NODE_ENV=test pm2 start app.js

It will output test, but if I then do:

NODE_ENV=development pm2 restart app.js

It will still output test.
Intended or not, seems a bit counter intuitive to me :).

actually it gets worse. The same effect as above is achieved if instead of restart you use start on a stopped process...

Can it be modified when the process is running? (assuming you change the ENV variables, then restart)
