INSTALL DOCKER ON KUBERNETES CLI HOW TO
Finally now that PubSub+ is available in Artifact HUB, the CodeLab will show you how to install a dev instance of PubSub+ in the environment using Helm.
Kubernetes allows you to launch and manage Docker containers across multiple servers in the pod.Windows 10 Helm / Kubernetes Development Environment SetupĪre you interested in trying out Kubernetes on your Windows PC? This CodeLab will show you how to setup a desktop Kubernetes environment using Docker Desktop, Windows Subsystem for Linux, Helm and Visual Studio Code. This network uses multiple servers to communicate back and forth. Minikube is a system for running a single node cluster locally and is excellent for learning the basics, before moving on to Kubernetes. The system should display the worker nodes that you joined to the cluster.Īfter following the steps mentioned in this article carefully, you should now have Kubernetes installed on Ubuntu.įor beginners who still have no experience of deploying multiple containers, Minikube is a great way to start. Switch to the master server, and enter: kubectl get nodes Wait a few minutes then you can check the status of the nodes. Repeat for each worker node on the cluster. Replace the alphanumeric codes with those from your master server. Switch to the worker01 system and enter the command you noted from Step 7: kubeadm join -discovery-token abcdef.1234567890abcdef -discovery-token-ca-cert-hash sha256:1234.cdef 1.2.3.4:6443 Verify that everything is running and communicating: kubectl get pods -all-namespaces Step 10: Join Worker Node to ClusterĪs indicated in Step 7, you can enter the kubeadm join command on each worker node to connect it to the cluster. This tutorial uses the flannel virtual network.Įnter the following: sudo kubectl apply -f Next, enter the following to create a directory for the cluster: kubernetes-master:~$ mkdir -p $HOME/.kube kubernetes-master:~$ sudo cp -i /etc/kubernetes/nf $HOME/.kube/config kubernetes-master:~$ sudo chown $(id -u):$(id -g) $HOME/.kube/config Step 9: Deploy Pod Network to ClusterĪ Pod Network is a way to allow communication between different nodes in the cluster. This will be used to join the worker nodes to the cluster. Once this command finishes, it will display a kubeadm join message at the end. Switch to the master server node, and enter the following: sudo kubeadm init -pod-network-cidr=10.244.0.0/16 Step 8: Initialize Kubernetes on Master Node If you have additional worker nodes, use this process to set a unique hostname on each. Next, set a worker node hostname by entering the following on the worker server: sudo hostnamectl set-hostname worker01 Then enter the command: sudo hostnamectl set-hostname master-node Start by disabling the swap memory on each server: sudo swapoff –a Step 7: Assign Unique Hostname for Each Server Nodeĭecide which server to set as the master node. Kubernetes Deployment Step 6: Begin Kubernetes Deployment
INSTALL DOCKER ON KUBERNETES CLI UPDATE
For update instructions, please see the developers’ instructions. Also, this process prevents apt from automatically updating Kubernetes. Different versions can create instability. Note: Make sure you install the same version of each package on each machine. Verify the installation with: kubeadm version Install Kubernetes tools with the command: sudo apt-get install kubeadm kubelet kubectl sudo apt-mark hold kubeadm kubelet kubectlĢ. The tool gives you command-line access to clusters.ġ. Kubelet is the work package, which runs on every node and starts containers. It fast-tracks setup by using community-sourced best practices. Kubeadm (Kubernetes Admin) is a tool that helps initialize a cluster. To add them, enter the following: sudo apt-add-repository "deb kubernetes-xenial main" Kubernetes is not included in the default repositories. Then repeat the previous command to install the signing keys. If you get an error that curl is not installed, install it with: sudo apt-get install curlĢ. Enter the following to add a signing key: curl -s | sudo apt-key add
INSTALL DOCKER ON KUBERNETES CLI SOFTWARE
Since you are downloading Kubernetes from a non-standard repository, it is essential to ensure that the software is authentic. Install Kubernetes Step 3: Add Kubernetes Signing Key To start Docker if it’s not running: sudo systemctl start dockerģ. Verify Docker is running: sudo systemctl status docker Set Docker to launch at boot by entering the following: sudo systemctl enable dockerĢ. Check the installation (and version) by entering the following: docker ––version Step 2: Start and Enable Dockerġ. Repeat the process on each server that will act as a node.Ĥ. Next, install Docker with the command: sudo apt-get install docker.ioģ.
