Cluster domain-c1 must have DRS enabled and set to fully automated to enable vSphere namespaces. All you need to do is get the management cluster id using the tkg get management-cluster command. Virtual Machine Hardware must be version 15 or higher. If you have multiple clusters, use the following command to get the id to name mapping: API Explorer This deprecation notice will be placed in the CPI logs when using the INI based configuration format. Wait for pods to start running and PVCs to be created for each replica. If nothing is listed here, make sure you have imported the OVA and converted it from a VM into an OVA template. It's up to you if you want to work with a command line or the browser-based API Explorer. [y/N]: y. different DataCenters or different vCenters, using the concept of Zones and Regions. NOTE: As of CPI version 1.2.0 or higher, the preferred cloud-config format will be YAML based. document.getElementById("ak_js_1").setAttribute("value",(new Date()).getTime()); This site uses Akismet to reduce spam. NTP Server: 192.168.250.1, vSphere Distributed Switch: VDS used for NSX-T It is mandatory to procure user consent prior to running these cookies on your website. Do you know if is the only way to route Control Plane with VCD? Note that the last part of the output provides the command to join the worker nodes to the master in this Kubernetes cluster. Here is some basic information about my setup: Prior to start with Kubernetes, you have to make sure that vCenter and ESXi are properly configured. vSphere 6.7U3 (or later) is a prerequisite for using CSI and CPI at the time of writing. If you want to use topology-aware volume provisioning and the late binding feature using zone/region, the node need to discover its topology by connecting to the vCenter, for this every node should be able to communicate to the vCenter. For production, VCF is the only (supported) option at the moment. The only supported option to enable vSphere with Kubernetes is by having a VMware Cloud Foundation (VCF) 4.0 license. Are you sure? Finally, hold Kubernetes packages at their installed version so as not to upgrade unexpectedly on an apt upgrade. The article covers evaluation options, licensing options, troubleshooting, and the initial configuration. To go to the CNS UI, login to the vSphere client, then navigate to Datacenter Monitor Cloud Native Storage Container Volumes and observe that the newly created persistent volumes are present. In the event Status shows the
state for more than 30 seconds then this usually means some sort of issue has occurred. It is important to understand that the problem is usually not related to the host being not connected to a VDS, it states that the NSX-T configuration has a problem. Open vSphere Client and navigate to Administration > Licensing > Licenses > Assets > Hosts, select your ESXi Hosts, click "Assign License" and set it back to Evaluation Mode. At this stage youre almost ready to go and you can start deploying non-persistent containers to test out the cluster. However, for the purposes of this post and to support older versions of ESX (vSphere 6.7u3 and vSphere 7.0) and vCenter were going to be using the TKG client utility which spins up its own simple to use web UI anyway for deploying Kubernetes. If you see compatible clusters, skip the troubleshooting part. I saw you used for workfload network the Ingress CIDRs: 192.168.250.128/27. It is recommended to not take snapshots of CNS node VMs to avoid errors and unpredictable behavior. Over the last year weve done a number of Zercurity deployments onto Kubernetes. As a vSphere administrator, you can review the VMDK that is created for your container volume. The Tanzu tkg is a binary application used to install, upgrade and manage your Kubernetes cluster on top of VMware vSphere. Use kubeadminit to initialize the master node. These cookies do not store any personal information. In other cases, some of the components need only be installed on the master, and in other cases, only the workers. DNS Server: 192.168.250.1 (Very important for PODs to access the Internet) Notes will be added for additional platforms. For more information about VMTools including installation, please visit the official documentation. VM Hardware should be at version 15 or higher. Pod CIDRs: 10.244.0.0/21 (Default Value) The following setups are using Ubuntu Linux. Lastly, youll need to give your current user permission to interact with the docker daemon. or separate network adapters). These should be the minimum versions installed. I'm using my default Management VLAN. This website uses cookies to give you the best online experience. Now that the CPI is installed, we can focus on the CSI. As a Kubernetes user, define and deploy a Kubernetes Service. Now we can install Docker CE. After your application gets deployed, its state is backed by the VMDK file associated with the specified storage policy. Dedicated Network Port (Second VDS) for Edge VMs (Required as you can't have Edge and Compute nodes on the same network adapter, in the same VLAN. Easy fix. Also critical if you intend on using persistent disks (persistent volume claims, pvcs) along side your deployed pods. Docker CE 18.06 must be used. If the license is expired, you have to reinstall, reset the ESXi host, or reset the evaluation license. We will now create a StorageClass YAML file that describes storage requirements for the container and references the VM storage policy to be used. An example Secrets YAML can be used for reference when creating your own secrets. This must be done in order to run commands on both the Kubernetes master and worker nodes in this guide. apt install -qy kubeadm=1.14.2-00 kubelet=1.14.2-00 kubectl=1.14.2-00. Please note that the CSI driver requires the presence of a ProviderID label on each node in the K8s cluster. This can be in your management network to keep the setup simple. These cookies will be stored in your browser only with your consent. With the networking configuration, you can use the defaults provided here. This should be the default, but it is always good practice to check. The following steps should be used to install the container runtime on all of the nodes. If youre configuring a new network please ensure nodes deployed to that network will receive an IP address via DHCP and connect to the internet. I'm deploying a Tiny Control Plane Cluster which is sufficient for 1000 pods. You may now remove the vsphere.conf file created at /etc/kubernetes/. Be aware that even the minimum setup is very resource-intensive. For physical setups, you should have 3 hosts with at least 6 cores and 64GB memory. If the problem is still active, check /var/log/vmware/wcp/wcpsvc.log for errors. You can just install ESXi and vCenter without a license to activate a fully-featured 60-day evaluation. For each tool, the brew install command for MacOS is shown here. This is surprisingly easy using the tkg command. Right, first things first. You should be able to configure the overlay, create a T-0 with an external interface, connect a T-1 to the T-0 using auto-plumbing, connect a segment to the T-1, create a virtual machine in that segment, and ping to the Internet from that VM. Run the following command to connect to the first container. We will use kubectl to perform the following steps. MongoDB will use this key to communicate with the internal cluster. The next stage is the define the resource location. Select Storage Policies for Control Plane Nodes, Ephemeral Disks, and Image Cache. In this step, we will verify that the Cloud Native Storage feature released with vSphere 6.7U3 is working. kubectl is the command line utility to communicate with your cluster. Don't you also need the vSphere Kubernetes add-on license? DCLI There are 3 manifests that must be deployed to install the vSphere Cloud Provider Interface. kubelet is the component that runs on all nodes in the cluster and performs such tasks as starting pods and containers. Subnet Mask: 255.255.255.0 IF you have followed the previous guidance on how to create the OS template image, this step will have already been implemented. To complete the install, add the docker apt repository. This website uses cookies to improve your experience while you navigate through the website. The discovery.yaml file must exist in /etc/kubernetes on the nodes. Love podcasts or audiobooks? We will return to that step shortly. You also have the option to opt-out of these cookies. VMware recommends that you create a virtual machine template using Guest OS Ubuntu 18.04.1 LTS (Bionic Beaver) 64-bit PC (AMD64) Server. This PersistentVolumeClaim will be created within the default namespace using 1Gi of disk space. If youve got stuck or have a few suggestions for us to add dont hesitate to get in touch via our website or leave a comment below. This file, which here we have called vsphere.conf has been populated with some sample values. In the vSphere Client, navigate to Developer Center > API Explorer and search for namespace If you are on a vSphere version that is below 6.7 U3, you can either upgrade vSphere to 6.7U3 or follow one of the tutorials for earlier vSphere versions. If you have multiple vCenter Server instances in your environment, create the VM storage policy on each instance. Perform this task on the worker nodes. Network: Choose a Portgroup or Distributed Portgroup We will be using flannel for pod networking in this example, so the below needs to be run on all nodes to pass bridged IPv4 traffic to iptables chains: That completes the common setup steps across both masters and worker nodes. The following sample YAML file includes the Space-Efficient storage policy that you created earlier using the vSphere Client. It also deploys the Cloud Controller Manager in a DaemonSet. Cluster domain-c1 is missing compatible NSX-T VDS. However, to use placement controls, the required configuration steps needs to be put in place at Kubernetes deployment time, and require additional settings in the vSphere.conf of both the CPI and CSI. That also applies when you have the Enterprise Plus license, which is widely known to be a fully-featured license. You can also monitor their storage policy compliance status. For those users deploying CPI versions 1.1.0 or earlier, the corresponding INI based configuration that mirrors the above configuration appears as the following: Create the configmap by running the following command: Verify that the configmap has been successfully created in the kube-system namespace. Scroll down to see the response: Cluster domain-c1 does not have HA enabled. However, weve created a separate Distributed switch called VM Tanzu Prod which its connected via its own segregated VLAN back into our network. You do not find anything called "Kubernetes" in the vSphere Client. It's a good practice to have them ready prior to start. The only issue I see is that the 3 Control Plane VMs have ~25% (1 core) at full load all the time. kubectl converts the information to JSON when making the API request. Note that the tags reference the version of various components. First, the Kubernetes repository needs to be added to apt. The csi.vsphere.vmware.com is the name of the vSphere CSI provisioner, and is what is placed in the provisioner field in the StorageClass yaml. The last and final stage is to again select the Proton Kube OVA which we downloaded earlier as the base image for the workers and management virtual machines. If that happens, reboot/remove/reconfigure might help. Note: If you happen to make an error with the vsphere.conf, simply delete the CPI components and the configMap, make any necessary edits to the configMap vSphere.conf file, and reapply the steps above. Check it out on VMware PartnerWeb. Service CIDRs: 10.96.0.0/24 (Default Value) For the next stage you can provide some optional metadata or labels to make it easier to identify your VMs. I have a question. Again, these steps are only carried out on the master. You need to copy and paste the contents of your public key (the .pub file). This is useful for switching between multiple clusters: With kubectl connected to our cluster lets create our first namespace to check everything is working correctly. It does not matter if you are in bash or the default appliancesh. We also use third-party cookies that help us analyze and understand how you use this website. This makes mongodb-0 the primary node and other two nodes are secondary. Internet access for all components (NAT is fine), 5 consecutive IP addresses for Kubernetes control plane VMs, 32 Egress IP addresses (Configured in CIDR (/27) notation. But opting out of some of these cookies may affect your browsing experience. Easy fix. Feel free to activate the vCenter license. Ingress CIDRs: 192.168.250.128/27 (Used to make services available outside Kubernetes) The purpose of this guide is to provide the reader with step by step instructions on how to deploy Kubernetes on vSphere infrastructure. On the Review and finish page, review the policy settings, and click Finish. When you don't have VCF or the Add-on license you have to set your ESXi hosts back to "evaluation mode", which is possible up to 60 days after installation. It's not a big issue, but power consumption in very high for my lab (770W, normally they are at 550W).
