cloudflared docker synology

Thanks James, glad it was useful! There is also an additional step you might wish to consider (Authenticated Origin Pulls) within the Origin Certificate settings page of Cloudflare. There was a problem preparing your codespace, please try again. docker-cloudflared-tunnel is a Docker image based on Cloudflare Argo Tunnel solution which provide Cloudflare daemon ad-hoc capabilities through Docker. I currently work with CloudFlare and a Synology at home but not using only Full mode (simple). A tag already exists with the provided branch name. I did some amalgamation of both, and the container keeps crashing. Click Next to continue. If you have any devices with a manually-configured IP address such as a home server or NAS, youll have to update their DNS servers to point to Pi-hole. Also, I am not sure if you are trying to connect one service or an entire network. Trying to make a Google login API. The links to the certificate can be found on the following page. Depending on how your host systems Linux kernel is configured, this option may not work at all. Honestly might be easier to create the tunnel through Cloudflare's ZeroTrust portal. We use cookies to ensure that we give you the best experience on our website. Also, we are going to use msnelling/cloudflared docker image because it has multi-arch support, so it can be deployed on ARM64/ARMv7 (such as Raspberry Pi etc). Given this adds an additional level of complexity I am not going to cover the Authenticated Origin Pulls feature in this article. It provides secure, fast, reliable, cost-effective network services, integrated with leading identity management and endpoint security providers. We want to ensure all our certificates are authenticated to help reduce the risk of man in the middle (MITM) attacks hence why I have chosen Full (strict) which validates all the certificates in the chain. By now many are familiar with Pi-hole. Learn more. For records that you cant proxy (for example MX records), if these point to your server, you may wish to consider using a relay service to be able to keep masking your IP (as discussed in this article). cloudflared gets the IP 172.30.9.2 and responds to DNS queries on the unprivileged port 5053. Seems great ! cloudflared provides another type of security with DNS over HTTPS. However, the rise of the Mozilla Foundation backed Lets Encrypt initiative has allowed anyone the ability to access free, secure SSL certificates signed by a trusted certificate authority recognised by most major browsers. container_name: cloudflared. Just one note which might help others with a dynamic IP, while Davids guide you linked to was really useful, I eventually ended up using Kirills script (https://github.com/mrikirill/SynologyDDNSCloudflareMultidomain) as it made it much easier to add multiple domains and subdomains within the DSM UI. So, how do I make sure there's a DNS resolver available to the Pihole when it starts up? This is a follow up to my "Docker and cloudflared" post. On your Manager node, copy over your compose and all referenced configs/secrets, and run docker stack deploy --compose-file docker-compose.yml cloudflared.To verify that your two services are running, docker stack services cloudflared.If everything is working at this point, I highly recommend removing those local files and setting up an automated deployment or using . We can verify that the cloudflared container is making this request by using: $ docker-compose -f "pihole-doh.yml" down to bring down the container and re-running the dig command. Note, the nameserver transfer process usually takes a few hours, but to propagate fully across the globe, youre probably talking at least 24 hours and maybe 48. Cloudflares Origin CA Root RSA Certificate, https://support.cloudflare.com/hc/en-us/articles/200169156-Which-ports-will-Cloudflare-work-with-, https://github.com/mrikirill/SynologyDDNSCloudflareMultidomain, https://my.domain.com/webman/3rdparty/Virtualization/noVNC/vnc.html?autoconnect=true&reconnect=true&path=synovirtualization/ws/70e6f827-cc1f-43cd-b778-00fbf369c689&title=NS1&app_id=94930208-63f7-4a80-b7e3-2ed78e595da1&kb_layout=en-gb&v=2.6.0-12122&app_alias=, https://www.cloudflare.com/en-gb/products/tunnel/, https://developers.cloudflare.com/cloudflare-one/tutorials/ssh/, Part 2: Are you feeling LUKy? Using the zero trust dashboard I began to create a tunnelI gave it a name and chose the location to install the cloudflared tunnel connectorI chose docker.I coped the command line that was . If any manual configuration is done to Pi-hole, that should probably be shared or synchronised between Pi-hole servers in a way that doesnt add points of failure (e.g. However, for your convenience the file download links are as listed: UPDATE Ive since been informed that ECDSA is no longer supported by DSM 6, so youll need to use RSA. Use Cloudflare DNS (1.1.1.1, 1.0.0.1) with DNS-Over-HTTPS Start docker run -d \ --name Cloudflared \ -p 54:53/tcp -p 54:53/udp \ srod/cloudflared-doh Update A CRON job is implemented to update cloudflared on a daily basis at 2am Resources https://developers.cloudflare.com/1.1.1.1/dns-over-https/cloudflared-proxy/ UPDATE Ive since been informed that ECDSA is no longer supported by DSM 6, so youll need to choose the RSA option. By the way, Synolgoy doesnt support ECDSA certificates (anymore). Incorrect preload configuration can expose you more than it protects you (as, to ensure your servers IP is kept masked via Cloudflares reverse proxy, you dont expose your server by opening up unnecessary ports, you use a firewall on your server that only allows traffic over essential ports and protocols, and where possible, limits traffic to only trusted clients. Given traffic from Cloudflare is being proxied, we need to make sure our Synology NAS isnt logging Cloudflares Serer IP addresses, and is instead logging the IP address of the originating request. Click on this and the following window will open where you need to enter this list of IP addresses provided by Cloudflare in CIDR format. Docker is a lightweight virtualization application that gives you the ability to run thousands of containers created by developers from all over the world on DSM. But only allowing admins to use SSH forces us to open up our devices to bigger risks just to do non-administrative tasks that is very common to do over SSH. restart: unless-stopped. But, it's working. Deploy your stack. image: cloudflare/cloudflared:latest #update the verion where necessary. For devices on your network to use Pi-hole as their DNS server, youll need to make some configuration changes. Updating the DNS Servers configuration to not select a "stock" upstream DNS server, and instead leaving the local DoH resolver selected seemed to be the fix I needed: Copyright2021-TIM'S BLOG. Im on DSM 7 and was able to get Cloudflare DNS proxy working by following your guide, then changing the DSM port to 8443, and adding the appropriate NAT Forward rule in the firewall. To log the correct IP address, we need to navigate to Control Panel -> Security and scroll down on the Security tab until we see the trusted proxies button. In typical home setups, the router is also the DHCP server and by default will tell devices to use the router as the DNS server too; an all-in-one solution. As shown below, you will have the option of letting Cloudflare generate a certificate, or using your own self-generated certificate (I personally chose to let Cloudflare generate the certificate). Ive had this blocked for years without any problems. This allows Pi-hole to talk to cloudflared without exposing cloudflared to the rest of the network. Save my name, email, and website in this browser for the next time I comment. These docs contain step-by-step, use case driven, tutorials to use Cloudflare . Turns out it is not that hard to do so. source: https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/install-and-setup/tunnel-guide poudenes February 12, 2022, 9:18am #2 After some more search I found this way how to do it directly on my NAS: Disclaimer: I have never setup a WARP to Tunnel network. Navigating to the three files you just generated for your Cloudflare Origin Certificate the files relating to the entries as follows: After clicking the blue OK button, your certificate should be imported successfully. The following window will appear. This site talks about using DNS over HTTPS from Cloudflare as the upstream DNS resolver for a Pihole, which has the added advantage of hiding your DNS queries from your ISP. We bind the DNS service to 0.0.0.0 to so it listens on all interfaces. This happened at about 11 PM, right when my youngest son was going to read an ebook on the tablet A quick fix applied, and a sleep later, it was time to resolve this mess. I am also trying avoid "hacking" the Synology, and leaving it as close to factory as possible so that future upgrades don't break everything. I would recommend changing the following settings: If you wish all your websites traffic to be over https, I would suggest you also enable the following settings under the Edge Certificate settings page. You can just ssh into your NAS and run the standard command. Depending on the type of network, it may be viable to block outbound port 53 at the firewall level to prevent circumvention of Pi-hole. Scuba diving. Since cloudflared is now a dependency of Pi-hole in our setup, well use docker-compose to orchestrate this. This article will take you through the steps I followed to set up my Synology NAS, using Cloudflare to proxy my web traffic and secure in-transit connections to my server. The script used an updated API, Cloudflare API v4. LUKS stands for LinuxUnifiedKeySetup and it is actually a key Read more. This all worked really great, until Watchtower updated Pihole. Join the internal network so Pi-hole can talk to cloudflared, # 2. This great tutorial explains one way to achieve this. Technology. However, make sure you check that compulsory https does not cause issues with your server (especially if enabling preload under HSTS, as you will not be able to remove compulsory https quickly if HSTS preload has been setup). I got this going easy enough. Installing this was straightforward using the usual mechanism. Ive tried it myself on my NAS but I found some limitations for my functionality. You should now have three files your origin certificate, your origin root certificate, and your origins private key. The /29 netmask provides 5 usable IP addresses (.1 is the virtual router); plenty for this setup. Securing a Raspberry Pi using a Zymkey4 Hardware Security Module. Thanks for the tip on the DDNS. Press question mark to learn the rest of the keyboard shortcuts. For this reason, you will need to access Pi-hole using your Synology NAS's IP address and a defined port. So, the goal is simple: Run Docker on the Synology, and run PiHole as a container. You will probably also have to write scripts to trigger at boot and after updates, to ensure your edits are not rewritten when your Synology updates or reboots. Synology does allow SAN lists within their Lets Encrypt interface, but restricts the length to a few hundred characters, significantly limiting the usefulness when managing several sub-domains. Once youve added/selected your chosen values, Click the blue next button to generate your Origin certificate. These samples offer a starting point for how to integrate different services using a Compose file. Synology provides a useful interface to create and renew Lets Encrypt certificates, but lacks wildcard support as things currently stand. Use your Synology admin account to connect. There, you will get a single line command to start and run your cloudflared docker container authenticating to your Cloudflare account. Our Support Techs suggest running a tunnel connected to a running docker container with Cloudflare's origin proxy server and Free SSL with this command: ./cloudflared tunnel --hostname domainname.com http://0.0.0.0:5003 Here, we use command tunnel and binary cloudflared to set up a connection between an open port. It is also wise to replicate your DNS records before making the switch to make the transition as smooth as possible (just make sure you proxy any record that points to your servers IP). The macvlan documentation shows how. 3. If you continue to use this site we will assume that you are happy with it. Marius Hosing has a great walk-through of how to do this through the GUI, so that at least told me it was possible. If I were setting this up now, Id probably use a Cloudflare Tunnel, which can also be used to proxy SSH traffic, as explained here: https://developers.cloudflare.com/cloudflare-one/tutorials/ssh/ The main benefit of Tunnels, over the steps Ive outlined above, is that you dont have to port forward/open ports on your router, so provided you trust Cloudflare, its even more secure. Docker on the Synology starts the container back up, but since nothing has really changed, the same issue occurs again. . Required fields are marked *. Arguably QuickConnect also offers some of this, but you cannot use your own custom domain, a free caching service helping reduce the load on my server. 2:48 Set the right. When testing that I was actually using Secure DNS and DNSSEC from Cloudflare's check tool, I would see inconsistent results. It works perfectly fine when accessing it through the NASs internal IP so has something to do with CF. I will try soon the part with intermediate certificates in order to pass to Full (stricit) mode. In this setup, we create another Docker network named internal that both the cloudflared and Pi-hole containers are connected to. Food. Edward, thank you so much for such an excellent, well explained article. https://developers.cloudflare.com/cloudflare-one/tutorials/warp-to-tunnel/. In this guide well setup cloudflare and Pi-hole together with docker-compose to create a portable and reproducible secure DNS solution. 0:58 Create folder. I created a cloudflare user and group, and gave it full access to /volume1/docker/cloudflared. https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/install-and-setup/tunnel-guide/remote/#set-up-a-tunnel-remotely-dashboard-setup. Watch the video with the NEW method, deploying the CF tunnel from the GUI: https://youtu.be/c4P31IhYx9Y 0:00 Intro. Just need a bit more lifting to get there with a couple more steps. I added some to stop ads showing up on my LG smart TV. The instructions from the cloudflare site for docker are: $ sudo docker run cloudflare/cloudflared:latest tunnel --no-autoupdate run --token . Your email address will not be published. Cool, works as designed.. right? So I am a newbie here and I wanted to set up a Cloudflare tunnel to my docker instance on my synology nas. Pihole has a docker image, so it was a matter of configuring this. As such, you will need to consider the security implications of disclosing your servers IP address (something Cloudflare will notify you about if your DNS records expose your IP). So, the goal is simple: Run Docker on the Synology, and run PiHole as a container. Ensure you can SSH into your Synology NAS. It also means only one service per port per Docker host. It is then down to you to select the services you wish to assign to the origin certificate (for example, Synology Drive Server and any Web Station virtual hosts). # but do not expose pi-hole to the internet! If you wish to use a split DNS for your network traffic, the lack of wildfire support, and character limits on SAN alternative names is pretty restricting if you have more than 5/6 sub-domains to manage. 2. The hugely popular built-in image repository, Docker Hub, allows you to find shared applications from other talented developers. Systems and Network administrator, general tinkerer. I have quite a few containers running, including Pi-Hole and cloudflared Home Assistant HomeBridge If you also opt for Cloudflare generation, you will be able to choose between either RSA (2048 bit) or the modern elliptical curve alternative (ECDSA) both very secure. cloudflared login Running the above command will launch the default browser window and prompt you to login to your Cloudflare account. For real usage, get started by creating a free Cloudflare account and heading to https://dash.teams.cloudflare.com/ -> Access -> Tunnels to create your first Tunnel. Traditional DNS is insecure and requests can easily be spied on or modified. Run the following dig command, a response should be returned similar to the one below: < 1024). Today I tried to upload a larger file (100Mb) through DSM but failed, receiving error msg "Connection failed. The yellow arrow indicates that a new update is available. I wanted to take it a step further. This is fine, but for redundancy and diversity, well add the Quad9 DoH servers as well. You need to navigate to click the Browse button for each of the entries. The filenames dont matter, but I tend to name mine using the following structure cloudflare.mycustomdomain.crt and cloudflare.mycustomdomain.key. By default, Cloudflare sets up a universal wildfire edge certificate for your domain (wildfire meaning the certificate will be valid for any sub-domain you create), as well as providing an interface to generate an origin certificate (should you need it). Type a description for the certificate (for example Cloudflare Origin domain name) and keep the Import certificate option checked. Setting Max Age Header (max-age) to the recommended 6 month value (unless youve enabled the preload option, for reasons explained below). There may be enhanced blocklists for your country. This stemmed from an issue within Pihole, where it had Google's DNS selected as the upstream DNS servers even though the DNS servers were defined as part of the environment variables. I dont believe you can proxy the SHH protocol with Cloudflare, it has to be HTTP traffic. Mounting an encrypted external drive using the Zymkey. Pi-hole with cloudflared provides a powerful security and privacy enhancement to any network. The instruction below shows how to use and configure cloudflared on docker with docker-compose. DNS over HTTPS prevents this by doing what it sounds like: sending your DNS requests over a secure HTTPS connection. I think these existed back when I wrote the article, but they only become a free service as of April 2021. 1:10 Download container image. By default, cloudflared uses the DoH service of Cloudflare. Now we could choose to just select Flexible or Full from the options available. This internal network will be 172.30.9.0/29. I have purchased a domain name and it is registered active on my Cloudflare account. Deploying configuration with something like Ansible could be a good solution. Any hints here? However, Flexible only secures the first part of the chain (from the browser to Cloudflare) the traffic sent from Cloudflare to our server not being encrypted. The problem is the cloudflare/cloudflared Docker image doesnt run as root so it wont have permission to bind to a privileged port (i.e. The is a script to be used to add Cloudflare as a DDNS to Synology NAS. However, in some instances this simply isnt possible, given that Cloudflare will only proxy traffic sent over the http protocol. A port on the container can be published to a port on the host when using docker run or in a docker-compose configuration. Cloudflare does not support every port on their Proxy (orange cloud), thus setting this up for the default DSM port is impossible. the web servers in use, the number of virtual hosts, and whether or not local network access is required). A WARNING stating "Misconfigured DNS in /etc/resolv.conf" may show in docker logs without this. You can also add custom blocklist rules. For those who dont know about Cloudflare, they are an American web-infrastructure and website-security company offering a variety of services at differing cost brackets. However, the way Ive got around it for Syncthing is to create a subdomain in Cloudflare (for example sync.mydomain.com, accessed over port 443). Certificate the certificate signing request you generated, Intermediate Certificate Cloudflares Origin Root CA file you saved, using the most up-to-date protocols the clients browser supports (note, for Cloudflares free accounts, ciphers are set based on your choice of protocol as listed, implementing policy mechanisms to guard against SSL Stripping and Man in the Middle attacks, enforcing SSL for all traffic (this is optional), setting the Minimum TLS Version to 1.2 this ensures only modern TLS protocols are used, setting Opportunistic Encryption to On this allows the client to benefit from HTTP/2 performance features if available, setting TLS 1.3 to On this enables the latest TLS protocol, if the clients browser is compatible, setting Automatic HTTPS Rewrites to On this helps to protect against mixed content errors (but note it doesnt necessarily rewrite all http links to https), configuring HTTP Strict Transport Security (HSTS) this is one of the more obscure and hardest to set up settings, but arguably also one of the most important settings (to avoid SSL stripping and man in the middle attacks, as, reading and accepting the acknowledgement deceleration shown after clicking the blue Change HSTS Settings button, Enabling Enable HSTS (Strict-Transport-Security), Enabling Apply HSTS policy to sub-domains (includeSubDomains). We value your privacy. Then on the Photos and Drive IoS app, when you put your hostname in, add a :8443 to the hostname and select HTTPS and it will work. The final step is to make sure the SSL/TLS encryption mode is set to full strict under the SSL/TLS Overview page of Cloudflare (as shown below). Wiring up the basics Synology has a Docker distribution for their devices, which was a great start. The process varies wildly by router so I cant provide direction, but login to your routers For higher availability on a LAN, the setup could be deployed to multiple Docker hosts and the IPs of the Pi-hole servers added to the DHCP configuration on the LAN. You can then use it to expose: Until fairly recently, this would have required purchasing of a certificate, rather than the use a free self-signed certificate. Hi Fabio, great, glad you found this tutorial useful! For those who need to assign the origin certificate to certain services, rather than making it the default, you will need to navigate to Control Panel -> Security -> Certificate, clicking on the Configure button as shown below. This is desirable as firewall rules and lock out events may be effected if our server is not seeing the request IPs, potentially having undesirable security implications. Trying to link one container ( jacket ) via GUYS I FINALLY FIGURED OUT DOCKER IM SO PROUD OF MYSELF. Most home LANs use DHCP to automatically assign IP addresses and DNS servers to devices. Installing this was straightforward using the usual mechanism. Are you trying to connect via SSH? Ive been trying to setup my Synology NAS with TLS on Cloudfare for about 2 days, and my problem ended up being the port, as pointed out by Jordy. Note, the private key will only be displayed once in this window, and it is not password protected/encrypted. I wanted to map volumes so the config info was stored outside of the container for easy updates. However, in the mean time, the best advice is: This is a good blog article. It is important you understand the implications of this action for non-https traffic. The Prometheus metrics HTTP server apparently has a default behaviour of randomly generating a port to listen on. This setting allows your server to cryptographically validate that a web request is coming from Cloudflares servers, stopping circumvention of Cloudflares security measures if your servers IP is accidentally leaked. No more punching holes in the firewall and opening stuff directly to the internet, plus the ability to give specific people/friends access to only the resources they need. Click on "Server Update Available" to download the right software version. With macvlan, Docker can create a new network that generates MAC addresses for containers and lets them have routable IPs on our LAN. This is very easy to do, you simply navigate to the SSL/TLS settings for your domain within Cloudflare's administration pages, selecting the "Origin" tab and then clicking on the blue "Create Certificate" button as pictured below. This includes third-party cookies for that we use for advertising and site analytics.. Well create it by hand so that this network is usable by any docker-compose setup and not just the one well create later: Note: When attaching containers directly to a network, port mapping has no effect (i.e. You might like to do a followup article with bot protection turned on as this will block some apps like DS-CAM from fully working (but can be mitigated with page rule to lower security on the websocket and API), Hi, Followed your guide which is great and works a charm (thanks), but Ive just setup a VM with the VMM and when trying to connect to a VM with the Connect button it loads the page but says Cannot connect to the server. Using Docker on Synology NAS is quite straightforward and can be accomplished via a nice web UI. In my experience, as long as its http protocol traffic, this will allow you to use Cloudflare for services utilising unsupported ports. Introduction and core concepts docker-cloudflared-tunnel is a Docker image based on Cloudflare Argo Tunnel solution which provide Cloudflare daemon ad-hoc capabilities through Docker. Once youre set up and Cloudflare has registered the nameserver switch, you are free to start configuring the SSL settings. To help you decide, an explanation of the workings and pros and cons of elliptical curve certificates can be found in this article (note either RSA or ECDSA will work with Synology DSM 6). Great work on this! Most routers can be reconfigured to assign custom DNS servers to clients. Effectively your site will have to run everything over https, and it is not easy to reverse this quickly. Do you have any suggestions or tips how to overcome this challenge? Now we could visit http://localhost or another user on the network can visit http://machine-ip-or-hostname. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Since few devices support DoH, cloudflared acts as a proxy between traditional DNS requests and DNS over HTTPS. In turn, cloudflared proxies the request to your applications. So, well configure Pi-hole to direct all requests to our running instance of cloudflared. Watchtower was a good choice, and there's no shortage of resources that discuss how to run this on a Synology (including another resource at Marius Hosting). Awesome Compose: A curated repository containing over 30 Docker Compose samples. Plex updates are necessary in order to avoid bugs, improve performance, and overall security. They both follow the convention of http:///dns-query for the lookup URL. setting Always Use HTTPS to On (this ensures all traffic to your server is secured), enabling preload under the HSTS configuration. You will need to click Add button, choosing the Add new certificate option before clicking Next as shown below. If the goal is to make the cloudflared DNS service available to the LAN, we want it on the standard port 53. Image Variants Usage Quick Setup: When Cloudflare receives a request for your chosen hostname, it proxies the request through those connections to cloudflared. For example, I found this not to work on a Synology NAS. Read more to see how to. Create a secrets directory owned by root with mode 600, and any values you need to keep secret like your CLOUDFLARE_API_KEY, etc. Pi-hole and cloudflared relationship Docker macvlan DNS over HTTP Servers Option 1: Hidden cloudflared Internal network cloudflared Pi-hole pihole-compose.yml Testing Option 2: Attach cloudflared to the LAN Assign cloudflared an ip DNS port Metrics pihole-compose.yml Testing Next steps Configuration sync Blocking rogue DNS Adding blocklists
