Kubernetes is the latest cutting edge technology that is being massively adopted! It can be challenging to use, but it doesn’t have to be. The sooner you learn it, the better! • This video shows you that you can deploy your own personal kubernetes cluster from scratch in less than 5 minutes! • Useful Links: • Kubernetes Homepage: https://kubernetes.io/ • Kubernetes The Hard Way: https://github.com/kelseyhightower/ku... • Linux Academy! Certified Kubernetes Administrator Course: https://linuxacademy.com/course/cloud... • ------------------------------ • Chapters: • 0:00 Intro and Why Use Kubernetes • 3:27 Why AWS, why 3 servers, and why not EKS? • 6:52 My environment setup • 7:17 Tutorial run starts! • 12:36 An example of deploying Nginx on my new cluster! • • ------------------------------ • Steps and Commands: • (This assumes you have 3 servers up and running) • 1. On each server, install Docker • (Installation guide: https://docs.docker.com/engine/instal...) • curl -fsSL https://download.docker.com/linux/ubu... | sudo apt-key add - • sudo add-apt-repository deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable • sudo apt-get update • sudo apt-get install -y docker-ce • 2. On each server, install kubernetes • (Installation guide: https://kubernetes.io/docs/setup/prod...) • curl -s https://packages.cloud.google.com/apt... | sudo apt-key add - • cat lt lt EOF | sudo tee /etc/apt/sources.list.d/kubernetes.list • deb https://apt.kubernetes.io/ kubernetes-xenial main • EOF • sudo apt-get update • sudo apt-get install -y kubelet kubeadm kubectl • 3. On each server, enable the use of iptables • echo net.bridge.bridge-nf-call-iptables=1 | sudo tee -a /etc/sysctl.conf • sudo sysctl -p • 4. On the Master server only, initialize the cluster • sudo kubeadm init --pod-network-cidr=10.244.0.0/16 • (After this command finishes, copy kubeadm join provided) • 5. On the Master server only, set up the kubernetes configuration file for general usage • mkdir -p $HOME/.kube • sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config • sudo chown $(id -u):$(id -g) $HOME/.kube/config • 6. On the Master server only, apply a common networking plugin. In this case, Flannel • kubectl apply -f https://raw.githubusercontent.com/cor... • 7. On the Worker servers only, join them to the cluster using the command you copied earlier. • kubeadm join 172.31.37.80:6443 --token ... --discovery-token-ca-cert-hash ... • And that's it! You should now have a working kubernetes cluster! • --- • Great resources I used to learn how to work with Kubernetes: • 1. Linux Academy (https://linuxacademy.com/) • 2. Udemy: Docker and Kubernetes: The Complete Guide (https://www.udemy.com/course/docker-a...) • 3. Kubernetes Documentation (https://kubernetes.io/docs/home/) • 4. Just play with it! • --- • Music: https://www.bensound.com
