How I host all my docker services securely.

Cloudflare Tunnel is a service that lets you connect your web servers or apps to Cloudflare in a safe way. It does this by making a secret tunnel between your server and Cloudflare’s closest data center, using a small program called cloudflared. This way, you can keep your server IP addresses hidden, stop direct attacks, and use Cloudflare’s security and speed features. You can use Cloudflare Tunnel for different things, such as keeping web servers safe from direct attacks, making sure only the right people can access your internal apps, or connecting SSH servers, remote desktops, and other ways of communicating to Cloudflare. You can also run more than one cloudflared program within the same tunnel to share traffic among different servers.

Cloudflare Tunnel works by making a safe and secret connection between your web server or app and Cloudflare’s closest data center, using a small program called cloudflared. This program runs on your server and makes connections that only go out to Cloudflare, without opening any ports that can receive incoming traffic. This way, your server or app is not visible to the public internet and can only be reached through Cloudflare’s network. To use Cloudflare Tunnel, you need to make a tunnel thing in your Cloudflare account and give it a DNS name. Then, you need to install and run the cloudflared program on your server or device and set it up to connect to the tunnel thing. Once the connection is made, you can reach your server or app through the DNS name that goes to Cloudflare’s network.

Some of the benefits of using Cloudflare Tunnel are:

• You can keep your web servers safe from direct attacks, such as DDoS attacks or login attempts, by sending all incoming web traffic through Cloudflare’s network.
• You can make your web servers or other services more reliable by keeping them on your local network, where they may be more secure and easy to manage.
• You can serve traffic in a fast, safe, and good way, by using Cloudflare’s network of data centers and security features.
• You can make your application traffic secret and safe to any kind of infrastructure, such as public cloud, private cloud, Kubernetes cluster, or even a Mac mini under your TV.
• You can connect web servers, SSH servers, remote desktops, and other ways of communicating safely to Cloudflare, without showing them to the public internet.
• You can make sure only the right people can access your internal applications by using Cloudflare Access, a Zero Trust access service that checks users by major identity providers (like Gsuite and Okta) without the help of a VPN.

To use the docker container for Cloudflare Tunnel on Unraid, you can do these steps:

• Get the cloudflared docker image from the Community Applications or from the Docker Hub.
• Make a folder for keeping the configuration files, such as /mnt/user/appdata/cloudflared/.
• In Unraid terminal, run this command to let cloudflared use the Cloudflare site you want to make a tunnel with: 'docker run -it --rm -v /mnt/user/appdata/cloudflared:/home/nonroot/.cloudflared/ cloudflare/cloudflared:latest tunnel login'
• It will show you a link to Cloudflare. Open the link in your browser and pick a domain name to link with your tunnel.
• A file called cert.pem will be downloaded to your folder. This file has your details for connecting to Cloudflare.
