Env variables in production : Kubernetes Vue Vite

I have a VUE app along with vite. But having some problem to access environment variables from vite.config inside pod.

In my ”vite.config” i have a few things that configurable based on environment set by spec in Kubernetes.

• CAN NOT access env-variables in "vite.config" set by Kubernetes in production.
• CAN access env-variables in client-code
• CAN access env-variables when running in dev-mode
• CAN list environment variables inside pod and they are all there.

export default (mode: string) => {
  process.env = { ...process.env, ...loadEnv(mode, process.cwd()) };
  const APP_BASEURL = process.env.VITE_BASEURL;
  // APP_BASEURL always empty

  return defineConfig({
    base: `${APP_BASEURL}`,

Note: vue application is build with docker.

So my problem - how can i set APP_BASEURL inside my vite.config?
