vite vue 3 dockerfile in javascript

To containerize a Vue 3 Vite application using Docker, you can follow these steps:

1. Create a Dockerfile in the root of your Vue 3 Vite project.

2. Specify the base image for your Docker container. In this case, you can use node as the base image since Vue 3 Vite applications require Node.js to run.

   FROM node:14
   13 chars
   2 lines

3. Set the working directory inside the container. This is where your application code will be copied.

   WORKDIR /app
   13 chars
   2 lines

4. Copy the package.json and package-lock.json (or yarn.lock) files into the container and install the dependencies.

   COPY package*.json ./
   RUN npm install
   38 chars
   3 lines

5. Copy the rest of your application code into the container.

   COPY . .

   2 lines

6. Build the production version of your Vue 3 Vite application.

   RUN npm run build
   18 chars
   2 lines

7. Expose the port on which your application will run. By default, Vite uses port 3000, so you can expose that port.

   EXPOSE 3000
   12 chars
   2 lines

8. Specify the command to start your application when the container starts.

   CMD ["npm", "run", "serve"]
   28 chars
   2 lines

9. Save and close the Dockerfile.

10. Build the Docker image by running the following command in the same directory as the Dockerfile.

    docker build -t my-vue-app .
    29 chars
    2 lines

    This will build an image named my-vue-app based on the instructions in the Dockerfile. The -t option tags the image with a name.

11. Once the image is built, you can run a container by executing the following command:

    docker run -p 3000:3000 my-vue-app
    35 chars
    2 lines

    This will run a container based on the my-vue-app image and map port 3000 of the container to port 3000 of the host machine.

Your Vue 3 Vite application should now be running inside a Docker container.

Remember to replace my-vue-app with a suitable name for your application.
