海外TECH	DEV Community	Building your own private Kubernetes cluster on a Raspberry PI 4 with K3S	https://dev.to/sahan/building-your-own-private-kubernetes-cluster-on-a-raspberry-pi-4-with-k3s-4nfp	Building your own private Kubernetes cluster on a Raspberry PI with KSIn this article we will look at setting up your own private Kubernetes cluster on a Raspberry Pi using KS in your home Wi Fi network Our setup will be pretty simple single master and a single worker node You can always add more nodes if you like Here s a diagram to give you an idea of what we will be building today Topology of what we ll be building todayBasically we ll be tying two Raspberry Pis together with KS and connecting them to a local WLAN We can then deploy our workloads using a client your laptop which will be talking to the Kubernetes API just as you d normally with any other KS cluster Note that the local addresses shown in this post might be different what you have got in your home network Step The initial setupFirst we need to set up the Raspberry Pis to have an OS enable SSH little bit of configuration to be able to use KS If you haven t done a setup on Raspberry Pi in headless mode before I have a post describing just that Note that this is for Desktop version if you want it for other stuff That post can be found here I have listed down the specs and the OS versions I used for my kit x Raspberry Pi Model B GB RAM x GB Micro SD CardsRaspbian OS Lite edition based on Debian Buster Stackable caseHere s a sneak peek of my build ️You can now use Raspberry Pi Imager without using Balena Etcher to flash the micro SD card This will make selecting the OS version and flashing process easier In summary we will be looking at doing the following steps You need to do the following configs to both or more of your Raspberry PIsEnable ssh on both RPIsEnable cgroupsSet up wirelessEnable bit mode at the kernel levelBooting upSet up IP tablesAssign static IPsChange the hostnamesInstall KS Server on MasterInstall KS Agent on WorkerBefore booting up we need to do a couple of configurations as mentioned below Step Enable SSHOpen up the root of the micro SD card this would be mounted as boot you just flashed Create a blank file named ssh at the root of that folder touch ssh Step Enable cgroupscgroups is an essential kernel level feature which underpins the containerisation technology This allows the processes to run in isolation with a specific set of resource assigned to it Let s open up the root of the micro SD volume this would be mounted as boot you just flashed and edit the cmdline txt file Add the following line to the end of the file cgroup memory cgroup enable memoryYou might be wondering why are we doing this Here s an excerpt from the KS docs From the docs Standard Raspbian Buster installations do not start with cgroups enabled KS needs cgroups to start the systemd service cgroups can be enabled by appending cgroup memory cgroup enable memory to boot cmdline txt Step Setting up wireless modeI don t carry around my Raspberry Pi setup so I opted in to use my home Wi Fi network instead of ethernet Here s how I did it While at the root of the boot volume create a new file called wpa supplicant conf file and add the following lines to it country AUctrl interface DIR var run wpa supplicant GROUP netdevupdate config network ssid your networks SSID psk your networks password Take a note of the country field you can find them in here and make sure to replace that with the corresponding country code that suits you ssid and psk would be the name of your wireless network and the password respectively Step Run the kernel in bit modeNext up we will tell the Raspbian OS to run the kernel in bit mode This is required for KS Open the config txt file and add the following line to the bottom arm bit That s it Now insert the micro SD card to the Raspberry PI and boot it up Step Booting upWhen you boot up the RPIs for the first time it will take a couple of minutes to appear on your home network If you log in to the router dashboard you ll be able to see the RPIs with their IP addresses You can log in to them via ssh like so ssh pi Note that pi is the default user and raspberry would be the default password Make sure to change the default password with passwd command when you log in for the first time to both nodes Step Enabling static IP configurationWhen we boot up the RPIs KS connects to the worker nodes by using their IPs Since we will be using WLAN if we restart our nodes the IPs would be different and this setup would not work So we need to add a piece of config to assign static IPs to them There are a couple of ways you can do this Best option would be to use your router s DHCP server capabilities and make an address reservation You d need the device name and MAC address of the RPIs If not you can edit the etc dhcpcd conf file and let the RPI know which IP to assign itself I would recommend to add this just below “Example static IP configuration section so that it d be easier to find it in the future interface wlanstatic ip address static routers static domain name servers Once done it would look like this Make sure to update the IP addresses for each RPI Step Setup IP Tablessudo iptables Fsudo update alternatives set iptables usr sbin iptables legacy Step Change the hostname to something sensiblesudo vi etc hostnameThis file will only contain a single line so you can name it something that makes sense to you I renamed mine as controlplane for the master node and node for the worker node Next change the etc hosts file where it says raspberrypi to the name of your node sudo vi etc hostsHere s an example for the node node Make sure to reboot the RPIs once you have done all these changes Step Installing KS on the Master nodeTo install KS on your master node run the following command It will do all the bootstrapping it needs to do under the hood curl sfL sh As a side note I always run a sudo apt update amp amp sudo apt upgrade before installing anything Step The worker node setup amp agent registrationBefore set up the worker node we need to take the token from the server You need to run the following commands on the master node in order to get this token sudo cat var lib rancher ks server tokenThen you need run the following command on the worker node Make sure to update them according to your environment curl sfL KS NODE NAME node KS URL KS TOKEN token from above step sh Explanation of the variables KS NODE NAME name of the worker node you are configuring Remember that we set up the hostnames in step KS URL the IP address of your master node The default KS server port is so keep it unchanged KS TOKEN Token that we received from the from the KS server Eg Kxxxxxxxxxx server xxxxxxxxxxxxYou d see INFO systemd Starting ks agent message and it s ready to go That s it you can now run commands and see it in action You will need to sudo su in order to run commands on the master node kubectl get nodes ConclusionBy the end of this article I hope you have your ks cluster up and running If you ran into issues let me know in the comments below In the next article we will look at deploying a sample application and see the cluster in action I m hoping to publish a script to automate most if not all of these steps pretty soon Until next time References	2021-08-14 12:25:00
