Multiple Domains

Since Sliplane currently doesn’t support multiple custom domains on a single service, you’ll need a separate redirect service if you want to handle both example.com and www.example.com. This guide shows you how to set up a simple NGINX-based redirect service.

Prerequisites

• A Sliplane account
• A service with a custom domain setup (example.com in this case)

Setting up the Redirect Service

Create a new Dockerfile:

FROM nginx:alpine

COPY nginx.conf /etc/nginx/conf.d/default.conf

EXPOSE 80

CMD ["nginx", "-g", "daemon off;"]

Create an nginx.conf file:

server {
    listen 80;
    server_name www.example.com;

    location / {
        return 301 https://example.com$request_uri;
    }
}

Replace www.example.com and example.com with your domains.

Push both files to any Github repository.

Deploy the service to Sliplane:

• Create a new service
• Set PORT environment variable to 80
• Set the custom domain to your www domain (e.g., www.example.com)

Now, when users visit your www domain, they will be automatically redirected to your apex domain while preserving the path and query parameters.
