Setting Environment Variables at Deployment

[ganta]

I want to deploy a project with a Node module on a private registry added as a dependency.

I configured .npmrc following:

//npm.pkg.github.com/:_authToken=${NPM_TOKEN}
@scope:registry=https://npm.pkg.github.com

However, I cannot pass environment variables to the build process with the firebase deploy command.

So the authentication error has occurred in the deployment process.

The official document said, "You can set the $NPM_TOKEN environment variable with the --set-build-env-vars argument to your gcloud functions deploy command." https://cloud.google.com/functions/docs/writing/specifying-dependencies-nodejs#private_modules_from_other_repositories

However, since I am using Firebase, I need to use the firebase command, not the gcloud command.

I want to pass environment variables to the build process in the firebase deploy command as well.

Trying to setup a Shopify Checkout Extension and for the love of god cannot find a way to add environment variables at deployment and I'm stuck at:

Missing Shopify API Key Your app is running without the SHOPIFY_API_KEY environment variable. Please ensure that it is set when running or building your React app.

In their docs, it takes 5 minutes to enter them using Heroku and Fly.io. I'm still a relatively new developer so I've been having a hard time trying to figure out how I can get this to work.

@cd-blanche Could you open a separate issue? I think what you're seeing is different from the original feature request here.

This also affects us and I think this is a big step backwards in DX terms. Some projects use more complex configurations that include for example bucket names but also other runtime relevant data. With the new defineString functionality we could only use simple strings (obviously) during deployment time. But we would like to keep a unified configuration, that is loaded from a json string.

A feature to load the variables from .env files during deploy time would make that also possible without having to use hundreds of defineString calls. Currently all envs are loaded after function hooks are evaluated which makes nested complex json configurations impossible for run and deploytime.

// in v1 by calling functions.config() to load json in deploy and runtime
// this won't work since .env is not loaded at deploy time so function trigger bucket is undefined
const complexConf = JSON.parse(defineString('SOME_ENV_VARIABLE').value()) as ComplexConfigInterface

exports.myConfiguredFunc = storage({bucket: complexConf.documentPipeline.bucketInbound}).onFinalize(()=>{
const url = complexConf.fancyImageCropperServiceUri
}

I am also encountering the exact same problem. Getting the below error when I run the command firebase deploy --only functions --set-build-env-vars NPM_TOKEN=${NPM_AUTH_TOKEN}

error: unknown option '--set-build-env-vars'

@ganta did you manage to find a workaround?

@dooleyb1 Unfortunately, the only way is to embed the token directly in the .npmrc and then run the firebase deploy command.

Our project involves multiple node_modules that all are expected to read their environmental variables from process.env and setup themselves accordinly. However because the environmental variables are only defined within the function body, our libraries cannot be configured properly. Isn't there any workaround for this? If I am not mistaken, there are multiple node libraries that depend on configuration of process.env?

Experiencing the same situation as the original issue here.

We have several npm packages published in Github private package repositories. We then have a Firebase functions project that use them as dependencies, and builds & deploy via Github Actions.

The build workflow works well : it uses a github-provided secret token in env variables to fetch these packages. However, in the deploy workflow, the deployment step fails because each firebase function that need to be deployed is rebuilt during the "firebase deploy" command execution, via a separate Google Cloud Build process (i.e. executed outsite the Github action).

From what I understand, it fails with an "Unauthorized" error because Github requires the token to fetch the packages from private repositories.

The --set-build-env-vars argument from gcloud doc cannot be used, because it is not recognized by the firebase deploy command, and there doesn't seem to be any alternative solution or workaround to pass an env variables to the build processes.

We really hope to see this feature as this is important for our use case & I'm sure there are plenty of other cases where an env variable is needed at build time for firebase functions.
