Caddy

Overview​

In this guide we will be using Caddy as a reverse proxy to access the Remnawave panel. We will point a domain name to our server and configure Caddy. Caddy will handle issuance of the SSL certificates by itself.

warning

You need to have a registered domain name to continue.

Point domain to your server​

Check your server's IP address. It is better to use a static IPv4 address.

Now, you need to point your domain name to this IP address.

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 are using Cloudflare, you need to add a A/AAAA record (for IPv4 and IPv6 respectively) to your DNS records.

Log in to your Cloudflare account here and select the desired domain.

On the left side of the page, click on DNS and then click on Records. Click on Create record.
Set the Type to A and the Name to @.

info

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

Enter your server's IP address in the IPv4 address field. and click on Save.

Now you need to wait a while for the DNS records to be updated.

info

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

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

static

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

Caddy configuration​

Simple configuration​

Create a file called Caddyfile in the /opt/remnawave/caddy directory.

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 the 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 docker-compose.yml file in the /opt/remnawave/caddy directory.

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'
            - '0.0.0.0:80:80'
        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 the login page.
