It’s worthwhile setting up backups of your storage, longhorn can be provided with a S3-compatible or NFS-compatiable storage. Kubernetes has become the Swiss Army knife of distributed computing. Traffic on TCP:80 and 443 must be directed to the ingress service using it’s IP — from there it will be routed to the correct application depending on the domain name, and we can host virtually unlimited number of websites that way. From the time Kubernetes was born in the labs at Google by engineers Joe Beda, Brendan Burns, and Craig McLuckie and then contributed to the open source community, it has become the de facto orchestration platform for containers, enabling easier development, scaling and movement of modern applications between on-premises datacenters and the cloud and between the multiple clouds … A range for static IPs assigned to important devices in your home network, it typically starts with your router, i used 192.168.0.1–255.

Home Assistant is open source home automation that puts local control and privacy first. With you every step of your journey. Hundreds of lines of infrastructure, everyone doing their own thing, and reinventing the wheel. You can only install Rancher on. This article discusses some of the challenges involved with managing and troubleshooting Kubernetes networking for large-scale production deployments. It might be of interest as another alternative to use something like k3s.io/ as a lightweight method of setting up a kubernetes cluster - supposedly works great on a few raspberry pis on a home network! Host apps at Home. Watch Kelsey Hightower deliver an awesome presentation on Kubernetes via several demos during his keynote talk on the KubeCon 2017. The first step is to create some VMs. Both Red Hat and CoreOS have been part of the Kubernetes community since Google launched the project in mid-2014.

Please use TLS, authentication options in the ingress, and be careful exposing your router or anything else sensitive. This is great, and honestly the best way to experience Kubernetes. After hitting my limit with minikube, I decided to give this a try. Begin installing K8S with it. Nothing I try seems to be able to access the cluster after it seems to have successfully built. Deploying home automation with Rasbperry Pi(s) is a relatively new approach, but one which has many advantages. Kubernetes overview: Above: Kubernetes Components by Julia Evans I am a college grad living in Canada, with an avid interest in programming and system administration. Kubernetes is an open source container orchestration engine for automating deployment, scaling, and management of containerized applications. They don’t have to run in your cluster — Amazon/Azure/GCP offer PAAS versions with their managed K8S serviceg. Like many techies out there, I’ve accumulated various Raspberry Pi like development boards over the years. Set the following vlaues, in addition to defaults: Save the resulting file as traefik-customised.yaml and delete the original — otherwise K3S will revert all changes and deploy Traefik the way it was. Replace the server: https://127.0.0.1:16443 with the domain name of the you spesified above — for example k3s.timmy.com. A Kubernetes home lab is the place to learn container orchestration before attempting an enterprise deployment. My home networks weren't always very complicated, but they ran a few services that I enjoyed having available, so it suited me. Serverless Kubernetes home-lab with your Raspberry Pis 12 October 2017 on raspberrypi , Raspberry PI , swarm , serverless , docker , arm , openfaas This guide shows how to build your own Serverless Kubernetes cluster with Raspberry Pi and OpenFaaS . You can spend more time improving your cluster and deploying prometheus, grafana, and other services, or you could jump straight in and host your blog, or whatever else you have on your mind. Kubernetes (K8s) is an open-source system for automating deployment, scaling, and management of containerized applications. ways to design an IOT network. To proceed, make sure you are comfortable with basic kubernetes concepts, know what’s a master node, an agent, a LoadBalancer service, a deployment, ingress, persistent volume, etc. That is why we are going to look at setting up Kubernetes ourselves. I use a custom vCenter template in my lab, but if you do not have one of those, you can follow these simple steps. If you have different classes of disks, like SSD and HDD, use. Do not modify existing kubernetes resources — K3S has an annoying add-on-like system, where it will monitor manifests in /var/lib/rancher/k3s/server/manifests/ for changes, and deploy them into your cluster. If you wish to expose some HTTP service on your LAN, such as your router’s dashboard, a NAS or some other device, you can create an endpoint and a corresponding service, then use Ingress to direct HTTP traffic as usual. If you can monitor progress of a certificate being issues with kubectl describe certs and debug issues by checking logs of the cert manager pod. Validate your setup by updating your ingress with TLS settings and an annotation that informs cert manager that it should create a certificate: You should see a pod appear with acme in it’s name — it’s responsible for responding to Let’s Enrcypt acme challenge. And also like many techies, most of them have been sitting in a “tech all use someday” drawer. Also, a secret will be created, and it will contain tls.crt and tls.key records. The actual range you use does not matter, you could leave default router subnet and use the ‘higher’ end IPs of 220–250 for static IP and load balancing. On my 6 node cluster, it usually takes about 10–15 minutes for the cluster to be completely setup and running.

The cluster will serve real workloads — we will deal with exposing it to the internet, IP assignments in home network, reasonable security, distributed storage and monitoring.
