Caddy

Overview​

In this guide we will use Caddy as a reverse proxy for requests to Remnawave. We will redirect a domain to our server and configure Caddy. Caddy will handle issue of SSL certificates by itself. Complete Quick Start and Env Variables before continuing.

Configuration​

Requirements:

warning

You should have a registered domain name to continue.

Point domain to your server​

Check out your server IP address, it is better to use a static IPv4 address.

Now, you need to point your domain to your server.

For example, it will be my-super-panel.com -> 193.122.122.122.

There are two ways to do this:

  1. Use a DNS provider (e.g. Cloudflare, Google Cloud, etc.)
  2. Use a registrar (e.g. Namecheap, etc.)

DNS provider​

If you use Cloudflare, you need to add a record to your DNS.

Log in to your Cloudflare account here. Select domain, which you want to point to your server.

On the left side of the page, click on DNS and then click on Records.

Click on Create record.

Select Type as A and Name as @.

info

If you want to use subdomains, you should write subdomain name (e.g. panel) in the Name field.

In the IPv4 address field, you should write your server IP address.

Click on Save.

Now, you need to wait for the DNS to be updated.

info

There are a big difference between yellow cloud (domain is proxied with Cloudflare) and grey cloud (domain is not proxied with Cloudflare) in the Cloudflare control panel.

We will return later to this topic in this guide, but for now it really depends on you.

If Cloudflare works fine in your region, it is better to proxy the domain with Cloudflare. (Yellow cloud)

static

Some DNS providers have a different interface, but the process is the same.

Caddy configuration​

Simple configuration​

Create a file Caddyfile in the /opt/remnawave/caddy folder.

mkdir -p /opt/remnawave/caddy && cd /opt/remnawave/caddy && nano Caddyfile

Paste the following configuration.

warning

Please, replace REPLACE_WITH_YOUR_DOMAIN with your domain name.

Review configuration below, look for red highlighted lines.

Caddyfile
https://REPLACE_WITH_YOUR_DOMAIN {
        reverse_proxy * http://remnawave:3000
}
:443 {
    tls internal
    respond 204
}

Create docker-compose.yml​

Create a file docker-compose.yml in the /opt/remnawave/caddy folder.

cd /opt/remnawave/caddy && nano docker-compose.yml

Paste the following configuration.

docker-compose.yml
services:
    caddy:
        image: caddy:2.9
        container_name: 'caddy'
        hostname: caddy
        restart: always
        ports:
            - '0.0.0.0:443:443'
        networks:
            - remnawave-network
        volumes:
            - ./Caddyfile:/etc/caddy/Caddyfile
            - caddy-ssl-data:/data

networks:
    remnawave-network:
        name: remnawave-network
        driver: bridge
        external: true

volumes:
    caddy-ssl-data:
        driver: local
        external: false
        name: caddy-ssl-data

Start the container​

docker compose up -d && docker compose logs -f -t

Open the panel in the browser​

Open the configured domain name in the browser and you will see login page.
