[SOLVED] How to Run a Vite Development Server Inside a Docker Container

In this article, we will look at how to run a Vite development server inside a Docker container. Vite is a new build tool. It makes working on frontend projects much easier. When we use Vite with Docker, we can create separate spaces for our apps. This helps our applications run the same way no matter where we put them. We will show you different ways to set up and configure a Vite development server in a Docker container. This will help us improve our development work.

Here are the solutions we will talk about in this article:

Solution 1: Setting Up Dockerfile for Vite Project
Solution 2: Configuring docker-compose for Development Environment
Solution 3: Exposing Ports for Vite Development Server
Solution 4: Volume Mounting for Live Reloading
Solution 5: Using Environment Variables in Docker for Vite
Solution 6: Running Docker Container with Hot Module Replacement

By the end of this guide, we will understand how to run a Vite dev server inside a Docker container. We will see how Docker helps us have a smooth development experience.

For more info, you may find these links useful:

Check our guide on how to manage Docker containers for more ideas.
If you want to learn about environment variables in Docker, we will also explain that.

Let’s start with the solutions!

Solution 1 - Setting Up Dockerfile for Vite Project

We want to run a Vite development server in a Docker container. First, we need to create a Dockerfile. This file tells Docker what environment and tools our Vite project needs. Here is a simple guide to make the Dockerfile.

Create a Dockerfile: In the main folder of your Vite project, make a new file called Dockerfile.
Define the Base Image: We will use a Node.js image as the base. Pick a version that works with your project. For example, we can use Node.js 16.
Set the Working Directory: We will set a working directory inside the container. This is where our application code will go.
Copy Package Files: We need to copy the package.json and package-lock.json files to the working directory.
Install Dependencies: We will run the command npm install to get the needed packages.
Copy Application Code: Next, we copy the rest of our application code into the container.
Expose Ports: We will expose the port that Vite will use. The default port is 5173.
Define the Command: Finally, we will use the CMD command to run the Vite development server.

Here is an example of what our Dockerfile should look like:

# Use the official Node.js image as the base image
FROM node:16

# Set the working directory in the container
WORKDIR /app

# Copy package.json and package-lock.json
COPY package*.json ./

# Install the project dependencies
RUN npm install

# Copy the rest of the application code
COPY . .

# Expose the port that Vite will run on
EXPOSE 5173

# Command to run the Vite development server
CMD ["npm", "run", "dev"]

Building the Docker Image

After we set up the Dockerfile, we can build the Docker image. To do this, we run this command in the terminal. Make sure we are in the same folder as the Dockerfile:

docker build -t vite-app .

Running the Docker Container

Once we build the image, we can run the Docker container with this command:

docker run -p 5173:5173 vite-app

This command links port 5173 of our host to port 5173 of the container. This way, we can access the Vite development server at http://localhost:5173.

By doing these steps, we will have a working Docker setup to run our Vite development server inside a container. If we want to learn more about Docker settings, we can check how to mount host volumes into Docker for better development.

Solution 2 - Configuring docker-compose for Development Environment

We can run a Vite development server inside a Docker container. Using docker-compose helps us manage our application better. Here are the steps to set up docker-compose for our Vite project.

Step-by-Step Configuration

Create a docker-compose.yml file: In the main folder of our Vite project, we need to create a file called docker-compose.yml.

Define the Services: We have to define the services that our Vite application needs. Here is a simple setup:

version: "3.8"
services:
  vite:
    image: node:16
    working_dir: /app
    volumes:
      - .:/app
    ports:
      - "3000:3000"
    command: npm run dev
    environment:
      - NODE_ENV=development

Explanation of the Configuration

version: This tells the version of the Docker Compose file format.
services: This lists the different services in our application.
- vite: This is the name of the service that runs the Vite development server.
  - image: This tells which Docker image to use. Here, we use the official Node.js image version 16.
  - working_dir: This sets the working folder inside the container.
  - volumes: This connects our current folder (.) to /app in the container. It helps us get live updates for our code.
  - ports: This connects port 3000 on our computer to port 3000 in the container. So we can access the Vite server from our computer.
  - command: This tells what command to run when the container starts. We use npm run dev to start the Vite server in development mode.
  - environment: This sets the environment variable NODE_ENV to development for our application.

Running the Docker Compose Configuration

To start the Vite development server with the settings in docker-compose.yml, we run this command in the terminal:

docker-compose up

This command will build the Docker image if needed and start the Vite development server. We can go to http://localhost:3000 in our web browser to see our Vite application.

Hot Module Replacement (HMR)

With this setup, we also get Hot Module Replacement (HMR). Any changes we make to our code will show up in the browser right away. We do not need to reload the whole page. This helps us work better during development.

By using this docker-compose setup, we can manage our Vite development environment easily. Our code stays organized and portable. For more settings, we can check the docker-compose documentation.

Solution 3 - Exposing Ports for Vite Development Server

When we run a Vite development server in a Docker container, we need to expose the right ports. This helps us access our development environment from our host machine. By default, Vite runs on port 5173. We need to set up Docker to expose this port.

Step-by-Step Guide to Expose Ports

Update Your Dockerfile: If we do not define the port in our Dockerfile, we can add the EXPOSE command. This tells Docker that the container listens on the specified network ports when it runs.
```
# Dockerfile
FROM node:16

WORKDIR /app

COPY package.json ./
RUN npm install

COPY . .

EXPOSE 5173

CMD ["npm", "run", "dev"]
```

Modify docker-compose.yml: If we use docker-compose, we can set the port mapping in our docker-compose.yml file. This helps us map the container’s port to a port on our host machine.

version: "3.8"

services:
  vite-app:
    build: .
    ports:
      - "5173:5173" # Maps host port 5173 to container port 5173
    volumes:
      - .:/app # Mounts the current directory to /app in the container
    environment:
      - NODE_ENV=development

Running the Docker Container: After we set up the Dockerfile and docker-compose.yml, we can build and run our Docker container.
```
docker-compose up --build
```
Accessing the Vite Development Server: When the container is running, we can access the Vite development server by going to http://localhost:5173 in our web browser. This port mapping lets us connect to the Vite development server running inside the container like it is running natively on our host machine.

Important Considerations

We should make sure no other services are using port 5173 on our host machine to avoid conflicts.
If we want to change the port for Vite, we can update the vite.config.js file. For example, to run Vite on port 3000, we can add this configuration:
```
// vite.config.js
export default {
  server: {
    port: 3000,
  },
};
```
Then, we need to update the Dockerfile and docker-compose.yml to match this new port.

By following these steps, we can expose the necessary ports for our Vite development server inside a Docker container. This makes development and testing easier. For more info on managing Docker ports, we can check this guide.

Solution 4 - Volume Mounting for Live Reloading

We can enable live reloading in a Vite development server that runs inside a Docker container by using volume mounting. This lets changes we make to our local files show up right away in the Docker container. This is important for a good development experience.

Step-by-Step Guide for Volume Mounting

Dockerfile Configuration: First, we need to make sure our Dockerfile copies our project files into the container. Here’s a simple example:

# Use the official Node.js image
FROM node:16

# Set the working directory
WORKDIR /app

# Copy package.json and package-lock.json
COPY package*.json ./

# Install dependencies
RUN npm install

# Copy the rest of the application code
COPY . .

# Expose the port that Vite will run on
EXPOSE 5173

# Command to start the Vite development server
CMD ["npm", "run", "dev"]

Setting Up docker-compose.yml: Next, we can use docker-compose to manage our Docker container easily. Here is an example of docker-compose.yml that mounts our local project folder into the container:

version: "3.8"

services:
  vite:
    build: .
    ports:
      - "5173:5173" # Map host port 5173 to container port 5173
    volumes:
      - .:/app # Mount the current directory to /app in the container
    environment:
      - VITE_DEV_SERVER_HOST=0.0.0.0 # Allow external connections

Running the Docker Container: After we set up our Dockerfile and docker-compose.yml, we can start our Vite development server with this command:
```
docker-compose up --build
```
Accessing the Development Server: Now we can open our web browser and go to http://localhost:5173. We should see our Vite application. Any changes we make to our files will now make the app reload live.

Important Notes

Network Configuration: When we set VITE_DEV_SERVER_HOST=0.0.0.0, we make sure that the Vite development server can be reached from outside the Docker container. This is key for live reloading to work right.
Volume Mounting: By mounting the whole project folder (.:/app), we can edit files on our host computer and see changes in the container. But we should be careful with this in production. It may show sensitive files by mistake.
Performance: Volume mounting can sometimes cause slowdowns, especially on non-Linux systems like macOS or Windows. If we have lag issues, we might want to use a different setup for development or make our Docker setup better.

For more details on mounting volumes, we can check this guide.

Solution 5 - Using Environment Variables in Docker for Vite

Using environment variables in a Docker container for a Vite development server is important. It helps us set up different parts of our application. We can configure things like API endpoints, feature flags, and database connection strings without putting them directly in our code. Here is a simple way to manage environment variables in Docker for a Vite project.

Step 1: Create a `.env` File

First, we need to create a .env file. This file goes in the main folder of our Vite project. It will store our environment variables. Here is an example of what it can look like:

VITE_API_URL=http://localhost:5000/api
VITE_FEATURE_FLAG=true

We must use the VITE_ prefix. This is needed for Vite to show these variables in our application code.

Step 2: Update the Dockerfile

Next, let’s change our Dockerfile. We will copy the .env file into the Docker image. Here is an example of a Dockerfile:

# Use the official Node.js image
FROM node:16

# Set the working directory
WORKDIR /app

# Copy package.json and package-lock.json
COPY package*.json ./

# Install dependencies
RUN npm install

# Copy the rest of the application code
COPY . .

# Copy the .env file
COPY .env .env

# Expose the port the app runs on
EXPOSE 3000

# Command to run the Vite development server
CMD ["npm", "run", "dev"]

Step 3: Configure `docker-compose.yml`

If we use Docker Compose, we can also add environment variables right in our docker-compose.yml file. Here is an example:

version: "3.8"

services:
  vite:
    build:
      context: .
      dockerfile: Dockerfile
    volumes:
      - .:/app
    ports:
      - "3000:3000"
    environment:
      VITE_API_URL: http://localhost:5000/api
      VITE_FEATURE_FLAG: true

This setup will send the environment variables to the Vite container. We can also use a .env file to load variables automatically.

Step 4: Accessing Environment Variables in Vite

In our Vite application, we can access these environment variables with import.meta.env. For example:

console.log(import.meta.env.VITE_API_URL); // Outputs: http://localhost:5000/api

Step 5: Running the Docker Container

To start our Vite development server with the right environment variables, we run:

docker-compose up --build

This command will build our Docker image and start the Vite development server. It uses the environment variables we set up in Docker.

Conclusion

Using environment variables in Docker for a Vite development server gives us a flexible way to set up our application. We can handle different environments easily without changing our code. For more details on using environment variables in Docker, check out this guide on Docker environment variables.

Solution 6 - Running Docker Container with Hot Module Replacement

To use Hot Module Replacement (HMR) for our Vite application in a Docker container, we need to set up the Vite dev server. HMR helps us see changes in our app right away without refreshing the whole page. This makes our development work better.

Step 1: Change Your Vite Configuration

First, we should check that our Vite project is ready for HMR. Vite usually turns on HMR by default. But we must make sure it is set up right. In our vite.config.js, we can set the server settings like this:

import { defineConfig } from "vite";

export default defineConfig({
  server: {
    host: "0.0.0.0", // Let access from outside the container
    port: 3000, // Default port for Vite
    strictPort: true, // Stops Vite from using a different port
    hmr: {
      protocol: "ws", // Use WebSocket for HMR
      host: "localhost", // This should match our host
    },
  },
});

Step 2: Change Dockerfile

We need to make sure our Dockerfile opens the port that Vite uses for HMR. Here is an example of a Dockerfile:

# Use the official Node.js image
FROM node:16

# Set the working directory
WORKDIR /app

# Copy package.json and package-lock.json
COPY package*.json ./

# Install dependencies
RUN npm install

# Copy the application code
COPY . .

# Expose the Vite port
EXPOSE 3000

# Start the Vite dev server
CMD ["npm", "run", "dev"]

Step 3: Change docker-compose.yml

If we use Docker Compose, we need to add the right settings in our docker-compose.yml file. Here is an example:

version: "3.8"
services:
  vite-app:
    build:
      context: .
      dockerfile: Dockerfile
    ports:
      - "3000:3000" # Connect host port 3000 to container port 3000
    volumes:
      - .:/app # Connect the current directory to /app in the container
    environment:
      - NODE_ENV=development

Step 4: Running the Container

After we set up our Dockerfile and docker-compose.yml, we can build and run our container with HMR. We use this command:

docker-compose up --build

Step 5: Accessing Your Application

After running the command above, we can open our Vite dev server with Hot Module Replacement by going to http://localhost:3000 in our web browser. Any changes we make to our code should start HMR, giving us a smooth development experience.

If we need more settings or help, we can check the article on how to use environment variables in Docker. This can help us change settings for different environments.

Conclusion

In this article, we looked at different ways to run a Vite dev server inside a Docker container. We covered important steps like making a Dockerfile, using docker-compose, and setting up live reloading with volume mounting. These steps help us work better and faster by using Docker’s container features.
