MicroK8s is a lightweight, zero-ops Kubernetes distribution that has received CNCF certification. All Kubernetes services are executed natively (i.e., without the use of virtual machines) and are packaged as a snap, which includes all necessary libraries, binaries, and the most widely used Kubernetes add-ons. The speed at which you may download a few hundred megabytes limits installation, and MicroK8s can be deleted without leaving any trace.
MicroK8s is an open-source solution that automates the administration, scaling, and deployment of containerized applications. You can use it to quickly set up a small single-node cluster in your local setting. It offers the fundamental Kubernetes component capabilities in a compact form factor that scales from a single node to a high-availability production cluster. MicroK8s also wants to make it easier to construct K8s and cloud-native applications. The steps below will show you how to install Kubernetes development cluster with microk8s. ..
Steps to install Kubernetes development cluster with microk8s
Set up hostnames
k8s-cli set-hostname microk8s1 k8s-cli set-hostname microk8s2
If you are having trouble logging in, try the following:
Make sure that you are using the same username and password that you used when you signed up for your account.
Make sure that your computer is connected to the internet and that your browser is up-to-date.
Try refreshing your browser page (F5 or Refresh button on most browsers) or clicking the Reload button on your browser toolbar. ..
Install the Kubernetes software on your computer.
Connect to your Kubernetes cluster using the kubectl command-line tool.
Change the name of your microk8s2 node to k8s2-microk8s2.
Update your Kubernetes configuration files using the kubeconfig command-line tool. ..
sudo nano /etc/hosts Add the following lines to the file: 127.0.0.1 localhost localhost 127.0.0.2 mycompany1 mycompany1 127.0.0.3 mycompany2 mycompany2 127.0.0.4 mycompany3
192.168.1.1 192.168.2.1 Now you’ll need to create a file called “hosts” in your home directory and add the following lines: 192.168.1.1 localhost 192.168.2.1 localhost You can now restart your computer and test the setup by visiting http://localhost in your browser ..
Install microk8s
sudo apt-get install microk8s Step 2: Log into your second machine and follow the same instructions, but replace “microk8s” with “docker”.
- Install microk8s on both machines.
- Log into your first machine and install the software with the command: sudo apt-get install docker .
- Log into your second machine and follow the same instructions, but replace “microk8s” with “docker”. ..
sudo adduser microk8s Step 3: To start using the microk8s cluster, you’ll need to issue the following command: sudo nano /etc/sysctl.conf and change the following line to point to the location of your microk8s cluster’s configuration file: .microk8s.io.default_port=80
mkdir -p $HOME/.kube Step 4: Copy the contents of the downloaded kubernetes.tar.gz file to the $HOME/.kube directory: cp -r kubernetes.tar.gz $HOME/.kube ..
chmod -R 777 ~/new_directory This will give the new directory the necessary permissions to be used as a working directory. ..
Step 5: Log out and log back in.
sudo apt-get install python-apt This will install the Python package manager and enable you to install and manage Python packages.
Join nodes
sudo apt-get update Step 2: On the machine that will serve as your printer, issue the command: sudo apt-get install cups Now that you have installed the necessary software, you can begin printing. First, open a document in your editor of choice and print it to your printer. Next, open a document in your browser and print it to your controller. ..
join -f “SELECT * FROM users” This will join all the tables in the users table into a single table, and output the result to the console.
netstat -an | grep “inet6” If the connection is successful, you will see a line that says “inet6 up” in the output. If not, please check your network configuration and try again. ..
Node1: ClusterName: Cluster1 Node2: ClusterName: Cluster2 Node1 and Node2 are both members of the same cluster. ..
kubeadm join –worker node1 If you want to add a node as a control plane node, you’d use the –control-plane flag like so: kubeadm join –control-plane node1 ..
In less than five minutes, a two-node Kubernetes development cluster has been set up. This is an excellent approach to get started with container programming.
Final Words
To install Kubernetes development cluster on a microk8s platform, we recommend using the following steps:
- First, create a new Kubernetes development cluster. This will require at least two nodes running Kubernetes.
- Next, install the required components for Kubernetes development on the nodes in your cluster. These components include the kube-proxy, kube-controller-proxy, and kube-daemon instances.
- Finally, set up networking and storage for your Kubernetes development cluster. This will include setting up an IP address and port for each node in your cluster and creating appropriate volumes for holding data and applications.
