I have a minikube setup where I have an API written in SprintBoot APP and have a separate REACT APP for UI.
In the deployment YAML file for REACT, I am setting one of the env variables that are available from a config map. However, when I do process.env.VARIABLE, it gives me undefined. I am pretty sure I am using it the wrong way and hence want to know if there any way to access a system environment variable inside the react code.
Sample code in REACT (NOT using my variable. Rather just a PATH variable):
onClickFunction() {
console.log("Clicked!");
alert('Button clicked! Env val = '+String(process.env.PATH));
}
In the alert, I see undefined. But when I did a bash into the pod, I see this:
$ kubectl exec -it react-js-567dd44ccc-2kdbz -nem bash
root@react-js-567dd44ccc-2kdbz:/app# echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
root@react-js-567dd44ccc-2kdbz:/app#The configmap is giving me the spring boot service name so that I can use it to call my API from UI. I am just trying to access that variable name here. Is this the right way to do this? Or should I be building this in an entirely different way?
May be, you have require exact path to .env file.
Try this...
const result = require('dotenv').config({ path: '/full/custom/path/to/your/env/vars' })
if (result.error) {
throw result.error
}
