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.

I'll go there, i don't constantly post questions but I've just been recently having alot of issues with CNI's, I might just delete this post

 

[EDIT (solved)]: Turns out, cilium did not remove its network links, and somehow kept updating to my current CIDIR leading to a duplicate, removing the links worked.

I keep on getting issues with CNI and networking.. I just want my cluster to work.. anyways

Apr 28 17:14:30 raspberrypi k3s[2373903]: time="2025-04-28T17:14:30+12:00" level=error msg="flannel exited: failed to register flannel network: failed to configure interface flannel.1: failed to set interface flannel.1 to UP state: address already in use"

How do i see what is using flannel Here is my server arguments:

ExecStart=/usr/local/bin/k3s \
    server \
        --kubelet-arg=allowed-unsafe-sysctls=net.core.rmem_max,net.core.wmem_max,net.ipv4.ip_forward \
        --flannel-backend vxlan \
        --disable=traefik \
        --write-kubeconfig-mode 644

So I am using the default flannel backend, I tried repeatedly uninstalling then re-installing k3s, I deleted the current flannel interface with ip link, there is no other k3s instance is running, so why am I getting this issue?

I increase envoys memory requirement to 1gb, did not fix the issue.

[–] [email protected] 1 points 1 week ago (1 children)

Well I switched to cilium, same issue, and the reason I started using a CNI earlier than I intended was because flannel didn't work.

This issue might seem complex but could you tell me some debugging stuff and logs to try to maybe get to the source of the issue or atleast provide a way to reproduce my issue (so I could maybe file a bug report)

Does anyone know how to fix the memory issue with cilium? or could link me to the docs or any issues about this. I just followed the instructions to install cilium, most stuff is up, I think tje daemon set is down? more specifically this pod cilium-envoy-chzf8 is in a crashloop of this memory issue, I have 3gbs+ of RAM avalible, but I dont think cilium would take up the rest of my memory nor does it look like size is a issue, here is a example:

               total        used        free      shared  buff/cache   available

It was my backend, turns out, it forwards /nextcloud onto the nextcloud service, which does not know what to do with it unless I set something like site-url to include that path. So I made a middleware to strip the prefix, but now it cannot access any of its files because it will use the wrong path.

[–] [email protected] 1 points 1 week ago (7 children)

https://pastebin.com/RhU5xtma I cant access any external address including dns servers, so, there is no firewall running on my pi (the master node), I can set the nameserver to be 1.1.1.1 in the pods config and iirc that works, but inside the pod, it doesn't work, so how do i fix this? You probably need more information so i can share. I am running calico as my CNI

 

[EDIT] Soo.. kinda fixed? It was my backend, turns out, it forwards /nextcloud onto the nextcloud service, which does not know what to do with it unless I set something like site-url to include that path. So I made a middleware to strip the prefix, but now it cannot access any of its files because it will use the wrong path. I will look for siteurl settings but I dont think all of my services have one, so any advice would be appreciated for a general solution

So currently my raspberrypi is connected to my internet under the ip, 192.168.68.77, (I configured traefik to work with that host and alternative hosts if need be). According to traefik logs I think that it does not work because it is missing access to the api server, although i could be wrong, i installed traefik via helm, and I have a config file for it, and disabled the default traefik given by k3s. here is the traefik config and logs: config: https://pastebin.com/XYH2LKF9 logs: https://pastebin.com/sbjPZCXv pods and svcs (all): https://pastebin.com/4y8h5YUK

The ingress is exposed properly, I know because of the curl behavior, so traffic going to 192.168.68.77 is going to traefik, and trying any of the services I have exposed like /traefik or /nextcloud does not work (404 error):

Could you explain the steps to active your setup? I'm sure I can modify it for powerdns

[–] [email protected] 2 points 1 week ago (9 children)

Well, its kube-dns, and it simply, does not work, more specifically, it cannot resolve any external domains, I think it can resolve internal domains but I doubt thats working, but mainly it cant resolve external domains. I posted about it, here: https://lemmy.zip/post/36964791

Recently, it was fixed because I found the correct endpoint, and uhh, now it stopped working, I updated the endpoint to the newer one, but it went back to the original issue detailed in that post.

[–] [email protected] 1 points 1 week ago (11 children)

No, i want to replace kube-dns and coredns, and some of my applications will resolve the ip at my dns server, then try those ips within the server, but mainly I want to replace the current dns stack due to several issues.

[–] [email protected] 1 points 1 week ago

Know anything that can do what I want?

[–] [email protected] 1 points 1 week ago (2 children)

I assume external dns means it will add all the domains like ..svc.cluster.local entries to that, or just

 

By this I mean, I have a powerdns server running in my cluster, I would like Kubernetes to add/update dns entries in my dns server to reflect all services or any domains that would be used within the cluster, this is to fix a current issue I am having, and for general control and centralization purposes.

 
  --image=nicolaka/netshoot \
  --restart=Never \
  -- /bin/bash
If you don't see a command prompt, try pressing enter.
network-tools:~# cat /etc/resolv.conf
search default.svc.cluster.local svc.cluster.local cluster.local
nameserver 10.43.0.10
options ndots:5
network-tools:~# 

DNS does not work in my k8s cluster. I dont know how to debug this, this is all my logs are in Coredns and kubedns:

[WARNING] No files matching import glob pattern: /etc/coredns/custom/*.server

This probably isnt enough, but what more can I do to debug this? I dont think its anything to do with my CNI, I am using calico, 1.1.1.1 as a nameserver or any nameserver works, but the issue is that internal to external dns mappings do not work, dns cannot resolve outside. Maybe not inside either according to this:

spiderunderurbed@raspberrypi:~/k8s $ kubectl run -it --rm network-tools-2   --image=nicolaka/netshoot   --restart=Never   -- /bin/bash
If you don't see a command prompt, try pressing enter.
network-tools-2:~# ping traefik.com
ping: traefik.com: Try again
network-tools-2:~# 

the services for kubedns and coredns does not work, but the logs as I sent above, dont show me much.

 

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?

https://pastebin.com/30Bh23EV and this:

  DVfio.configuration = {
        systemd.tmpfiles.rules = [
          "f /tmp/enable-vfio-switch 0644 spiderunderurbed users -"
        ];
        environment.variables = {
          KWIN_DRM_DEVICES = lib.mkForce "";
        };
        environment.extraInit = ''
                export KWIN_DRM_DEVICES=$(${vfio}/bin/vfio)
        '';
  };

So there is a issue with my configuration, so, you dont really need to understand nix, just like, look at my qemu hook script, its in plain sh, and the stuff above might be self explanitory, the issue is, my nvidia drivers are still being used, despite, setting KWIN_DRM_DEVICES to card0 so the logs of libvirtd looks something like this: https://pastebin.com/TaKrsY9S if setting kwin_drm_devices to my gpu card does not work, i dont know what does and can use help

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

 

My cluster has been showing my raspberrypi node as "Ready" but according to the description of the node, the last log was "NodeNotReady" all debug guides say look for any pressure, like disk, pid, or so on, but there is no pressure, no absence of network. Here is the logs of my pi and pi status: https://pastebin.com/UULz6Hcy My pods are stuck in unknown (except jellyfin which is awaiting another node to come on): https://pastebin.com/vw2masAC A description of one of my pods if that helps: https://pastebin.com/s5W03s0E

also i already tried re-installing k3s

 

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

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.
