When you build your Vite application, it generates static assets that, by default, do not include the protocol (http or https) in the URLs for assets. This means that the assets should be protocol-relative and should work with both HTTP and HTTPS as long as they are served correctly by your server.
However, if you're facing an issue where Vite is hardcoding HTTP URLs into your build, you might need to adjust your Vite configuration to ensure that it uses protocol-relative URLs or allows for environment-based configuration.
One way to handle this is to use environment variables to determine the protocol at runtime rather than at build time. You can use a placeholder in your Vite configuration and replace it with the appropriate protocol when the Docker container starts.
Here's a step-by-step solution:
- In your Vite configuration file (e.g.,
vite.config.js), use a placeholder for the protocol:
export default defineConfig({
// ... other configurations
base: process.env.ASSET_URL || '/',
});
- In your Dockerfile or entrypoint script, use
sedor a similar tool to replace the placeholder with the desired protocol based on an environment variable:
# Dockerfile or entrypoint.sh
# Set the default protocol to http if not specified
ASSET_PROTOCOL=${ASSET_PROTOCOL:-http}
# Replace the placeholder with the actual protocol
sed -i "s|process.env.ASSET_URL|'$ASSET_PROTOCOL://'|g" /path/to/dist/assets/index.html
- When running your Docker container, you can pass the
ASSET_PROTOCOLenvironment variable:
docker run -e ASSET_PROTOCOL=https -p 80:80 -p 443:443 your-image-name
This way, you can control whether your application uses HTTP or HTTPS without rebuilding the assets. The environment variable will determine the protocol at the time the Docker container starts.
Remember that for HTTPS, you will also need to configure your web server (e.g., Nginx, Apache) to handle SSL termination and serve your application over HTTPS. This includes setting up the necessary SSL certificates.
Please note that this solution assumes that your application can handle being served over both HTTP and HTTPS without any other changes. If your application has other dependencies on the protocol, you may need to adjust this solution accordingly.
