Cloudflare DDNS w/ Docker - Keep your public IP updated automatically

[@metalmanexetreme]

I’m definitely not knowledgeable enough to be messing with any of this yet, but I’m subbing to you so that when I do become proficient enough to mess with it I can come back and follow along

[@DanielTekmyster]

I am using cloudflare as my dyn dns also, love the control. Also using nginx reverse proxy

[@neilcoelho]

How to host a WordPress website using this? I'm not really a programmer, but want to selfhost my website.

[@KarlMeyer]

I still use DuckDNS. The docker container used to set it up is brain-dead simple.

[@IrishKingzz]

DuckDNS is the best. I tried to set up a reverse proxy but I'm to stupid to get it working

[@krzysi3k-yt]

I'm also using DucksDNS, python script scheduled in ci/cd pipelines, works flawlessly

[@darkzero4608]

Duck DNS won't work if ISP uses CG-NAT Network behind.

[@jmugoose30]

Why did you move away from tunnels? Seems you wouldn’t have to worry about up changes and would work with failover up changes.

[@RaidOwl]

Tunnels are bit more of a black box than standard https traffic through their proxy. There are pros and cons to each, but since I'm not CGNAT'd I stick with their proxy DNS.

[@MichelRibeiro-o2o]

I would like to congratulate you on your excellent work, I really like your videos. I would like to ask if possible if you could record a video explaining how to run nginx-proxy-manager together with traefik inside portainer, honestly this is an extreme headache for me and I really need to learn, I believe this is the question of several followers. Thanks in advance.

How is this different from just using the cloudflare-DDNS docker?

[@RaidOwl]

Probably no different. I assume both use ddclient and the Cloudflare api.

[@intertan]

Well, there is my Sunday project

[@ImARichard]

Just out of curiosity, is there a benefit to using the loadbalancer in cloudflare over just using standard DDNS updating of A records and using the Unifi WAN failover? Or just wanted to play around with the Cloudflare loadbalancing? Ive yet to be able to test it, but in theory if primary WAN goes down and you fail over to secondary long enough the DDNS container will just automatically fetch your secondary WAN IP and update your A records according.

[@RaidOwl]

Yeah that’s def another way to do it. But I’ve wanted to have an external LB for awhile and couldn’t pass it up for $5 haha

[@ImARichard]

@@RaidOwl fair enough, part of the fun of homelabbing is playing around with stuff just because you can anyway!

[@johnwauters584]

anyone know how to add a host to this after the container is created?

[@takeover4726]

all i get is error reading config file

[@gordonramsay3512]

Had the same problem, the config-example has broken json syntax. Use an online json checker on it, fix the error then paste it into notepad. After that fill in your subdomain names, api key and zone id then try restarting the container. Also worth checking if you provided the correct path in the docker-compose script.

[@fahmi8999]

I have question, I'm using dynamic IP and Cloudflare, i have configured all done. since my IP is dynamic, how to add subdomain? using A record? CNAME?

[@smallqwaro]

if there isn't anything that bypasses cloudflare from the internet then I think the arrows should just go from the internet to cloudflare to your modems.

[@borrachomejor6767]

Did you update your image to only support `arm` based processors recently? I originally set everything up using your image on an `amd64` machine but after making some changes and trying to restart the container I run into the below error. I only see a `:latest` tag on Dockerhub. I switched back to the `oznu/cloudflare-ddns` image and it seems to be running fine. `The requested image's platform (linux/arm64/v8) does not match the detected host platform (linux/amd64/v2) and no specific platform was requested`

[@fabiocanepa]

Is the load_balancer mandatory ? Because I have only one IP and for this reason I didn't create the load_balancer section in the conf file but when I execute the script I see this error: Traceback (most recent call last): File "/home/pi/docker/cloudflare-ddns/cloudflare-ddns.py", line 316, in updateIPs(getIPs()) File "/home/pi/docker/cloudflare-ddns/cloudflare-ddns.py", line 248, in updateIPs updateLoadBalancer(ip) File "/home/pi/docker/cloudflare-ddns/cloudflare-ddns.py", line 191, in updateLoadBalancer for option in config["load_balancer"]: ~~~~~~^^^^^^^^^^^^^^^^^ KeyError: 'load_balancer'

[@Dinez]

Thanks for sharing all the knowledge. Great Video.

[@NightHawkATL]

Great option for me once I get my static ip on my primary so if it goes out, I will be able to update from my secondary ISP if the primary fails.

[@DapperDuff]

What software are you using to diagram your setup?

[@RaidOwl]

draw.io

[@richcreedy4118]

i'm using a cloudflare tunnel

[@Zeluph]

Just a heads up, looks like the public IPs 2 seconds into the video weren't blurred!

[@RaidOwl]

They’re dummy ones ;)

[@tonyt852]

Thank you for sharing!

[@weaveman3]

I'm getting an "error reading config.json" message, and I have no idea why. I'm sure it's something simple and stupid that I've done (it always is), but I can't figure it out.

[@RaidOwl]

Feel free to join the discord and we’ll help you out.

[@longxuong803]

I got same error

[@Sapious1]

I've been researching this for 2 days, I am also getting the json file error... no answers yet.

[@RaidOwl]

are you including a load balancer section? I think the way it's written you at least need a blank one@@Sapious1

[@Sapious1]

@@RaidOwl thanks for the reply, it’s funny you mention that. I was wondering if I should leave it in, but I wasn’t sure how to comment it out because I’m not using a load balancer. Think I just need “” for blank?

[@Lunolux]

thx for the video, i'm in Europe and never hear or see an ip provide by ISP change O_o is that a think where you live thant your ip change during the year O_o that insane

[@TMoneyJones]

10/10 on information. 3/10 on entertainment. 😢 You better not be falling off. I want to say I know someone famous and your my best shot.

[@RaidOwl]

lol boy is it hard to make a Cloudflare DDNS video entertaining I tellyawhat

[@Pongo8844]

Too confusing for a tutorial

[@RaidOwl]

Nah

[@SpaceDorg]

Great

[@JamesTenniswood]

Or just use cloudflare tunnels. End of story
