I’ve been debugging a cloudflared tunnel issue in my homelab [1] all day today, and getting really frustrated. My issue ended up being that it was running twice, once without the correct config file and another with it. I believe that cacheing may have compounded the issue. In yesterday’s post I setup a cloudflared tunnel on my ubuntu server to expose applications running on the server to the internet. I’m setting up a new server and running cloudflared in its own vm. setup cloudflared tunnel on ubuntu [2] Check that dns is pointing to the correct tunnel # [3] dig subdomain.example.com traceroute subdomain.example.com Check that the tunnel is running # [4] export CLOUDFLARED_TUNNEL_ID = "my-tunnel-id" cloudflared tunnel list cloudflared tunnel info $CLOUDFLARED_TUNNEL_ID References: [1]: /homelab/ [2]: /setup-cloudflared-tunnel-on-ubuntu/ [3]: #check-that-dns-is-pointing-to-the-correct-tunnel [4]: #check-that-the-tunnel-is-running

I run a cloudflared tunnel on my ubuntu server to expose applications running on the server to the internet. I’m setting up a new server and running cloudflared in its own vm. Get the cloudflared binary # [1] sudo wget https://github.com/cloudflare/cloudflared/releases/latest/download/cloudflared-linux-amd64 -O /usr/local/bin/cloudflared sudo chmod +x /usr/local/bin/cloudflared # [2] Now setup the config directory. For the systemd service to work, the config file needs to be in /etc/cloudflared. I like to give my user rights to edit the config file without being sudo, we will do that here by creating a group cloudflared, add ourselves to the group, give ownership of /etc/cloudflared to the group, give group write access to the directory, and refresh groups. sudo mkdir -p /etc/cloudflared sudo groupadd cloudflared sudo usermod -aG cloudflared $USER sudo chown -R root:cloudflared /etc/cloudflared sudo chmod g+w /etc/cloudflared newgrp cloudflared login # [3] Now we can log into the domain zone with cloudflared. cloudflared tunnel login This will give a url, follow it in a browser to log in. cloudflared tunnel create <NAME> mv ~/.cloudflared/cert.pem /etc/cloudflared/cert....
