How do I use App Platform variables in Nginx with a Vite React application?

I am using Docker to containerize my React application, which I build using Vite. Locally I can use import.meta.env.VARIABLE_NAME to access environment variables in my .env file. When I deploy this to App Platform, though, the environment variables don’t work.

Here’s my nginx.conf file:

server {
  listen 80;
  root /usr/share/nginx/html;
  index index.html;

  location / {
    try_files $uri $uri/ /index.html;

Here’s the relevant part of my Dockerfile:

FROM nginx:1.23.3-alpine AS runner

COPY --from=installer /app/apps/web/dist /usr/share/nginx/html

# RUN rm /etc/nginx/conf.d/default.conf

COPY deploy/nginx/nginx.conf /etc/nginx/conf.d


CMD ["nginx", "-g", "daemon off;"]

In my app spec I define environment variables like this, but it’s not actually setting them in Vite/Nginx.

  - key: VITE_API_URL
    scope: RUN_TIME
    value: ${api.PUBLIC_URL}

I’m wondering what the solution for this is?

Hi there,

I believe that you would need to set the scope of the variable to BUILD_TIME and not only run time.

That way the variable will be available during the build process of your Docker image and should be passed to the vite build.

Let me know how it goes!
