Firebase functions - modify firebase functions:config programmatically

Question

I am hoping to achieve to update firebase functions config (env variables) programatically other than manually typing firebase functions:config:set I want to automate this process depending on the returned value from a post call inside the function and possibly invoke cloud run to achieve this.

I've tried below but only worked in local env.

const { exec } = require("child_process");

exports = module.exports = functions.https.onRequest(async (req, res) => {
    try {


            exec(`firebase functions:config:set hello.world="hhh"`, (error, stdout, stderr) => {
                if (error) {
                    console.log(`error: ${error.message}`);
                    return;
                }
                if (stderr) {
                    console.log(`stderr: ${stderr}`);
                    return;
                }
                console.log(`stdout: ${stdout}`);
            });
            res.status(200).send({ message: 'success' });

        }


    catch (e) {
        console.log('e :>> ', e);

        res.status(400).send({ status: res.statusCode, message: 'aborted' });
    }
})

If there's a way to achieve this, I'd like to know.

Also wondering if there's way to achieve this with cloud run.

Thank you.

There's no way to update the environment while a function is running. It requires a full redeploy from the CLI.
