Deploying from github does not read environment variable about caprover HOT 3 CLOSED

You're reading your variable in your frontend code. The env vars aren't available in frontend. They are available ONLY during runtime. I'm not familiar with ViteJS - but if I were to guess it probably needs the env var on build time:

I understand, you should pass the value of the environment variable inside the container.

captain-definition file:

{
 "schemaVersion": 2,
 "dockerfileLines": [
   "FROM node:18-alpine",
   "WORKDIR /app",
   "COPY ./package.json /app/",
   "RUN npm install && npm cache clean --force",
   "COPY ./ /app",
   "ARG VITE_HELLO_WORLD",
   "ENV VITE_HELLO_WORLD $VITE_HELLO_WORLD",
   "ENV NODE_ENV production",
   "RUN npm run build",
   "CMD [ \"npm\",\"run\", \"preview\" ]"
 ]
} 

• ARG VITE_HELLO_WORLD: Defines a build argument for the environment variable "VITE_HELLO_WORLD". This argument can be provided during the build process.

• ENV VITE_HELLO_WORLD $VITE_HELLO_WORLD: Sets the environment variable "VITE_HELLO_WORLD" to the value of the build argument. This allows the environment variable to be customized during container build, for example, when using CapRover.
