Does anyone know any courses for web javascript? like youtube courses and for web javascript, i mean writing js in script tags, using document and window, and intergrating backend with frontend no nodejs or stuff like that. Just javascript, being used in a script tag, being used to dynamically manipulate elements, the DOM, and such. Most tutorials I found was just, explaining how js works, i know how it works, I want to know how to do the communication between front-end and back-end.

[EDIT] I found one person, and while I would like it if you could tell me more courses, i will link his videos, Traversy Media did some videos on Javascript DOM, which basically does what I asked for, i made a playlist: https://www.youtube.com/playlist?list=PLDmZtFPxsV268gyN8XBTgXiVVRXtIRf2o

if for whatever reason the playlist goes down, just search for him. But I would like to hear about alternatives.

^ output of my resolv.conf and cloudflare logs

kube-system kube-dns ClusterIP 10.90.0.10 <none> 53/UDP,53/TCP,9153/TCP 2d15h

^ my service ip for kubedns

https://pastebin.com/BCBhh8aj

^ my cloudflare config

How come, despite there being no mention of 8.8.8.8 on my system, in any other dns file for kubedns, not in my resolv.conf, tunnels, is now, incorrectly, trying to use that, to resolve internal ips, it does not make any sense

I think internal DNS resolution is overall working fine, here is a example of me accessing traefik from one of my pods:

spiderunderurbed@raspberrypi:~/k8s $ kubectl exec -it wordpress-7767b5d9c4-qh59n -- curl traefik.default.svc.cluster.local 
404 page not found
spiderunderurbed@raspberrypi:~/k8s $ 

^ means traefik was accessed, it is accessed as its my ingress, and there is nothing about 8.8.8.8 in there, might be baked in my CF.

Title. I am in a k8s cluster, and I constantly get DNS issues in it, for some reason, it is using my resolv.conf, and since I have tailscale it tends to overwrite my resolv.conf, i don't think there is a way to fix it, also, I have multiple clusters and I don't know how to exactly use the proper names, I set up stuff like PowerDNS, but I want it so that, some of cloudflare tunnels queries goes through this nameserver, while some of it goes through other nameservers, the way k8s handles dns internally leads to some weird stuff where, if a DNS server says NXDOMAIN, it wont try the next one, and just general buggy behavior.

(to better explain, I dont have direct ips in my tunnel configuration, as I would have to change them often, I use DNS names, and intend to continue using DNS)

I find virt-manager hard to use, and not easily configurable, XML is the easiest but I don't always want to configure my vms in either a command-line or XML directly, is there any graphical alternative to virt-manager that uses the entire or part of the stack?

[spiderunderurbed@daspidercave:~]$ distrobox enter debian

How do i fix? This was created normally, the container, I dont know what more information to add

So I need help with a split dns approach, or a direct fix, normally when running my tunnel on the simplest configuration I get this error:

Couldn't resolve SRV record &{region1.v2.argotunnel.com. 7844 1 1}: lookup region1.v2.argotunnel.com. on 10.43.0.10:53: read udp 172.16.91.156:54443->10.43.0.10:53: i/o timeout

When I tried to change the nameserver to cloudflare to make it accessible I get this error:

Anyone know why cf tunnels is asking the wrong DNS server? I know i specified 1.1.1.1 but it should have also asked kubedns as I specified its ip I do have to specify its nameserver or else it does not work, it wont be able to connect to their argotunnel domain without going through 1.1.1.1

kube-dns   ClusterIP   10.43.0.10   <none>        53/UDP,53/TCP,9153/TCP   12d

also its the correct ip I would like it, if you cant give direct advice, to try this deployment, and add a custom dns server that idk, configures it so that correct ip queries goes to 1.1.1.1 and the rest kubedns, i dried coredns, and other dns servers and I couldnt get anything to work I am trying the nameserver 1.1.1.1 because otherwise I get the error mentioned above. and no, I am not running a firewall nor anything that should block it outside of k8s, as it runs perfectly fine on the host.

So I have a issue. whenever I accessed all of my services via 192.168.1.22/wordpress for example. it forwarded that /wordpress to the actual wordpress domain, leading to page not found, however when i strip the initial proefix, i can access the base page, however, when lets say wordpress wants any css or assets, it will look at 192.168.1.22/assets which wont work, so basically, I need a way for sort of, emulate the url paths, so it wont take actual queries to places that dont exist and tries to access resources the incorrect way, i know siteURL exists for WP, but i want a catchall solution which helps my other services.
