- I really like this idea for a homelab [1] jbod. Hardware Haven builds out Just a Bunch Of Disks using some pretty affordable hardware and has up to 16 disks added to his homelab with the os having full access to use with zfs.

Manufacturer Recertified Drives | Enterprise Grade Manufacturer Recertified enterprise drives work and look like new. Rebuilt by the manufacturer and quality tested to ensure they function as new, our recertified drives save on cost. Shop now! ServerPartDeals.com · serverpartdeals.com [1] For my next drive upgrade in my homelab [2] I am gong to be using one of these factory recertified drives from serverpartdeals.com. Found them on an LTT video awhile back. They are some lightly used and recertified, fully burnt in drives. Shop for drives that are certified once again by the manufacturer to work like new. Factory ReCertified drives are cost-effective alternatives compared to factory-sealed new counter parts. Additionally, unlike in mass production, the re-certification process involves closer attention to the overall operation of the hardware so that the re-certification will not have to happen a 2nd time Note This post is a thought [3].

linkding A self-hosted bookmarking service that is designed to be minimal, fast and easy to set up. linkding · linkding.link [1] linkding looks like an interesting alternative to thoughts. Thoughts is focused on the note being a value add tweet length blog post that you share to the public. This seems more focused on fire and forget with some note taking and search ability. I should definitely level up the search and tag discovery in thoughts. Note This post is a thought [2].

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....

Fitting two hard drives and an SSD in a Dell OptiPlex 7010 SFF The Dell OptiPlex 7010 SFF officially only has room for one 2.5" hard drive internally, I fitted two 3.25" hard drives and a 2.5" SSD in one. willj.net [1] This guy fit 2 3.5" drives and an sdd in a dell 7050 SFF. It looks tight, and there it probably not much airflow running in it, but its an impressive project. Note This post is a thought [2].

- Homelabbers have been some of the best co-workers I have ever had. Typically have a get shit done, If there’s a way I will find it kind of mentality. If you are struggling to get a job in tech right now its tough. Starting a homelab on a pc you pull out of the trash is a good way to get some experience that you can talk about in interview questions. Linked video has some great points!

External Link thoughts.waylonwalker.com [1] I was looking to add running kubernetes jobs to a python cli I am creating, and I found this solution, mostly thanks to ollama run mistral:7b-instruct-q4_K_M and my loose understanding of what the yaml syntax is supposed to look like for a kubernetes job. This will let me create a job in the cluster, choose the image that runs, the command that is called, and how long until the job expires and is cleaned up. While the job still exists I can go in and look at the logs, but once its ttl has expired they are gone. from kubernetes import client, config # Load the default kubeconfig config.load_kube_config() # Define the API client for batch jobs api_instance = client.BatchV1Api() # Create a new job object job = client.V1Job( api_version="batch/v1", kind="Job", metadata=client.V1ObjectMeta(name="myjob"), spec=client.V1JobSpec( ttl_seconds_after_finished=100, template=client.V1PodTemplateSpec( metadata=client.V1ObjectMeta(labels={"app": "myjob"}), spec=client.V1PodSpec( containers=[ client.V1Container( name="myjobcontainer", image="busybox", command=["ls", "/"], ), ], restart_policy="Never", ), ), backoff_limit=1, )...

[1] I was curious to see what was going on inside of my minio object storage. Great technique here by Frank to create an inspector pod, then you can do as you wish with the data. I created the manifest as pvc-inspector.yml apiVersion: v1 kind: Pod metadata: name: pvc-inspector spec: containers: - image: busybox name: pvc-inspector command: ["tail"] args: ["-f", "/dev/null"] volumeMounts: - mountPath: /pvc name: pvc-mount volumes: - name: pvc-mount persistentVolumeClaim: claimName: pvc-name Then used it like this. # create pvc-inspector pod kubectl apply -f pvc-inspector.yml # exec into inspector kubectl exec -it pvc-inspector -- sh # explore data ls /pvc # cleanup kubectl delete -f pvc-inspector.yml Note This post is a thought [2].
