Hi @Hùng Lê. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To create a .env file for a Nuxt application running in a Docker container on a VPS, you have several options: Option 1: Mount a local .env file into the container In your docker-compose.yml file, you can mount a local .env file from your VPS into the container: 
services:
  nuxt-app:
    image: your-nuxt-image
    volumes:
      - ./.env:/app/.env
    # other configuration
services:
  nuxt-app:
    image: your-nuxt-image
    volumes:
      - ./.env:/app/.env
    # other configuration
This approach is shown in one of the examples from the knowledge sources where they mount the .env file like this: 
volumes:
  - ./.env/:/src/.env
volumes:
  - ./.env/:/src/.env
Stack Overflow Post Option 2: Set environment variables directly in docker-compose Instead of using a .env file, you can set the environment variables directly in your docker-compose.yml: 
services:
  nuxt-app:
    image: your-nuxt-image
    environment:
      NUXT_PUBLIC_API_BASE: "<https://api.example.com">
      NUXT_API_SECRET: "your-secret-key"
    # other configuration
services:
  nuxt-app:
    image: your-nuxt-image
    environment:
      NUXT_PUBLIC_API_BASE: "<https://api.example.com">
      NUXT_API_SECRET: "your-secret-key"
    # other configuration
This approach is recommended in the Stack Overflow post where they suggest: 
environment:
  NUXT_PUBLIC_STRAPI_BASE_URI: "blablabla"
environment:
  NUXT_PUBLIC_STRAPI_BASE_URI: "blablabla"
Stack Overflow Post Important notes about environment variables in Nuxt 1. Development vs Production: .env files are automatically loaded during development and build time, but not in production. As the Nuxt documentation states:
"After your server is built, you are responsible for setting environment variables when you run the server. Your .env files will not be read at this point."
Nuxt Docs - .env 2. Runtime Config: For production, you should use Nuxt's runtime config system and set the environment variables when running the container: 
   // nuxt.config.ts
   export default defineNuxtConfig({
     runtimeConfig: {
       apiSecret: '', // can be overridden by NUXT_API_SECRET environment variable
       public: {
         apiBase: '' // can be overridden by NUXT_PUBLIC_API_BASE environment variable
       }
     }
   })
   
   // nuxt.config.ts
   export default defineNuxtConfig({
     runtimeConfig: {
       apiSecret: '', // can be overridden by NUXT_API_SECRET environment variable
       public: {
         apiBase: '' // can be overridden by NUXT_PUBLIC_API_BASE environment variable
       }
     }
   })
3. Docker CMD: When starting your container, you can pass environment variables to the Node.js process: 
   CMD ["node", "/app/server/index.mjs"]
   
   CMD ["node", "/app/server/index.mjs"]
Or with environment variables: 
   ENV NUXT_PUBLIC_API_BASE=<https://api.example.com>
   ENV NUXT_API_SECRET=your-secret-key
   
   ENV NUXT_PUBLIC_API_BASE=<https://api.example.com>
   ENV NUXT_API_SECRET=your-secret-key
Stack Overflow Post Remember that for security reasons, sensitive environment variables should not be committed to your repository and should be set at runtime in your production environment. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
