GitHub - johanhaleby/kubetail: Bash script to tail Kubernetes logs from multiple pods at the same time Bash script to tail Kubernetes logs from multiple pods at the same time - johanhaleby/kubetail GitHub · github.com [1] Kubetail is a pretty sick bash script that allows you to tail logs for multiple pods in one stream. Very handy when you have more than one replica running. wget https://raw.githubusercontent.com/johanhaleby/kubetail/master/kubetail chmod u+x ./kubetail Now with kubetail I can tail all the logs for every shot-wayl-one pod in the shot namespace. ./kubetail shot-wayl-one -n shot [2] Note This post is a thought [3].

- I am converting my docker compose env secrets over to k8s secrets. This guide was clear and to the point how I can replicate this exact workflow. First set the secret, the easiest way is to use kubectl wtih –from-literal because it automatically base64 encodes for you. kubectl create secret generic minio-access-key --from-literal=ACCESS_KEY=7FkTV**** -n shot If you don’t use the --from-literal you will have to base64 encode it. echo "7FkTV****" | openssl base64 Once you have your secret deployed, you have to update the container spec in your deployment manifest to get the valueFrom secretKeyRef. spec: containers: - env: - name: ACCESS_KEY valueFrom: secretKeyRef: key: ACCESS_KEY name: minio-access-key - name: SECRET_KEY valueFrom: secretKeyRef: key: SECRET_KEY name: minio-secret-key image: registry.wayl.one/shot-scraper-api name: shot-wayl-one ports: - containerPort: 5000 protocol: TCP resources: {} restartPolicy: Always Note This post is a thought [1].

External Link X (formerly Twitter) · twitter.com [1] Wow, shocked at these results. All this time I’ve been told and believed that k8s is incredibly hard, and you need a $1M problem before you think about it because it will take a $1M team to maintain it. So far my experience has been good, and I definitely do not have a $1M problem in my homelab [2]. [1] Note This post is a thought [3].

What a great example, If I’m looking at the second jQuery example, I have to dig into dev tools or make some assumtions that this team uses jQuery, and selects by id, therefore I can grep for $("#d1").

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, )...

How to kill process based on the port number in Linux Learn to kill a process by port in Linux using fuser, lsof, and ss commands. Essential for system admins managing network processes efficiently. LinuxConfig · linuxconfig.org [1] I’ve often struggled to find and kill a process using a certain port on archlinux. Mainly becuase most guides use netstat rather than ss. Here is how I just killed the process using port 5000 using fuser. sudo fuser -k 5000/tcp You can also get information about the process by running lsof ❯ lsof -i :5000 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME thoughts 1058292 waylon 11u IPv4 119622828 0t0 TCP *:commplex-main (LISTEN) Note This post is a thought [2].
