To get started start by cloning my orangepi repo at git clone Ĭreating network "opilbnode_default" with the default driver To test our cluster we will configure a simple node-based application with haproxy as load balancer and scale the containers. docker can be installed on all four nodes by running the following command on each node. In order to set up the cluster for either of Swarm or K8s, Docker needs to be installed needed. Ssh-copy-id Install docker and docker-compose on each node
The goal is to get ssh access to these four nodes without entering a password. Run the following commands from your laptop for each node. 192.168.0.100 docker1Īfter this setup, you should be able to ssh to each node using ssh 8. Update your laptop /etc/hosts as following. Configure hostname and ipaddress for each node as by running >armbian-config command. armbian-config is a base utility for configuring your board. Ssh to each node using the root:1234 and change the password.
Configure password, hostname and static IP Address for each node Note down the IP addresses of each node with nmap command. Then you should see a green flashing LED, which indicates there is SD card activity. Near the USB connector, you should see a solid red LED. your cluster should look like this.Ĭonnect your Orange Pi's to their power supplies, and make sure they boot properly. you need to center the Orange Pi on the case and drill 4 holes for each board. Since the cluster case is for Raspberry pi's and Orange Pi's are smaller in dimension. Let's build a four-node tower?īuilding the tower is a fun part, you don't actually need a tower, but this will help organize the cluster better. Other basic things needed, Micro SD Card reader (for flashing image), HDMI cable, USB mouse & keyboard, USB Hub for mouse and keyboard (Orange Pi has only one USB port), display monitor and a laptop (a MAC in my case). Here is Amazon list for easy access to this list. I do not have any association with these sellers, but it's pretty handy to get started quickly and make an awesome looking cluster. I am listing all hardware and software needed to create your mini-cluster and where you can buy them.
There is no proper documentation for configuring a Swarm or K8s cluster on Orange PI, so I am making this multi-part series of articles to share the information. Orange PI boards are inexpensive, very powerful new generation mini pcs (H6 Quad-core 64-bit ARM Cortex™-A53) suitable for IoT and Edge computing use cases. As a part of Vimana engineering, I have been configuring Orange PI clusters for demos with customers and partners.
