/README.md: -------------------------------------------------------------------------------- 1 | # Terraform vSphere Kubernetes automated lab 2 | ## Terraform vSphere Kubernetes automated Lab Build v1.0 - See the detailed blog post here: https://www.virtualizationhowto.com/2021/12/terraform-vsphere-kubernetes-automated-lab-build-in-8-minutes/ 3 | 4 | This is an automated Terraform script that: 5 | 6 | - Builds the (3) Ubuntu VMs using an Ubuntu 21.04 vSphere template (built with Packer as linked above) 7 | - Sets DNS - this is kind of kludgy how I am setting the DNS server. However, haven't found a reliable way to set this with Terraform as of yet. I welcome comments on this. 8 | - Installs all the available Ubuntu updates - runs in "non interactive mode." In doing some Googling found this to be effect to suppress the "service restart" prompts you get when installing Ubuntu updates. 9 | - Configures root for logging in via SSH - You can comment this out if needed as it doesn't really affect your Kubernetes install. You can always sudo the underprivileged user of your choosing. The Packer build I have linked to creates an ubuntu/ubuntu user. 10 | - Also sets a password for root - Again can be commented out 11 | - Installs prereqs for Docker, Docker keyring, and then installs Docker - Container runtime used for the automated build. 12 | - Installs prereqs for Kubernetes, kubeadm, and kubectl - Normal stuff needed for 13 | - Turns off swap 14 | - Puts Kubernetes, kubeadm, and kubectl on hold so these can be closely controlled 15 | - Change the Docker cgroup to systemd 16 | - Restarts Docker services 17 | 18 | After running the script, the resulting VMs are created in your vSphere environment ready to configure Kubernetes. 19 | 20 | ## Before running the script 21 | 22 | 1. Change the values in the .tfvars file in the parent folder to match your environment 23 | 2. There is hard coded IP addresses in the main.tf in each folder (kube-1, kube-2, kube-3) 24 | 3. There is a hard-coded DNS value in the main.tf for each kube-1, kube-2, and kube-3 folder in the provisioners section. You will need to change this. 25 | 26 | 27 | ## After running the script on the Kubernetes master/controller: 28 | 29 | If you use the naming I have used, this is . Run the following: 30 | 31 | ### Configure Kubernetes 32 | 33 | kubeadm init --pod-network-cidr=10.244.0.0/16 --ignore-preflight-errors=all 34 | 35 | ### Configure kubectl to work with your cluster 36 | 37 | - mkdir -p $HOME/.kube 38 | - sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config 39 | - sudo chown $(id -u):$(id -g) $HOME/.kube/config 40 | 41 | ### Install your Kubernetes networking (choose one of the below): 42 | 43 | Flannel 44 | - kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml 45 | 46 | Calico 47 | - kubectl apply -f https://docs.projectcalico.org/manifests/calico.yaml 48 | 49 | 50 | 51 | ## On the two worker nodes 52 | 53 | Run the kubeadm join command displayed on the Master/controller node, it will look like the following: 54 | 55 | kubeadm join 10.1.149.123:6443 --token pqrc0n.iow5e2zycn5bu1uc \ 56 | --discovery-token-ca-cert-hash sha256:7b6fd631048cc354927070a82a11e64e6afa539822a86058e335e3b3449979c4 57 | 58 | If you accidentally close your session and need to see the join command run the following on your master: 59 | 60 | - kubeadm token create --print-join-command 61 | -------------------------------------------------------------------------------- /kube_master/main.tf: -------------------------------------------------------------------------------- 1 | ##Provider 2 | 3 | provider "vsphere" { 4 | user = var.vsphere_user 5 | password = var.vsphere_pass 6 | vsphere_server = var.vsphere_server 7 | 8 | #
