Download PDF Feedback Updated on 12/07/2022 To provision a Tanzu Kubernetes cluster in an internet restricted ("air-gapped") environment, create a local content library and manually import each Tanzu Kubernetes release. Accessing default data source (Prometheus), Grafana from TKG Extensions comes with a default data source Prometheus running on the same TKC/Guest Cluster. Discover valuable resources for Kubernetes deployments on VMware Cloud Foundation, including guides, tools, and technical documentation for streamlined operations. Main steps: Configuration Storege Policy and Tags. The card labelled Tanzu Kubernetes Grid Service should have the name of the content library hosting the TKG VMs. Creation of the namespace. The download link will redirect you to the AVI Networks Portal. Read More . Read More. Create your first dashboard using the web interface. Unable to pull images from vSphere with Tanzu's Subscribed Content The update should take effect in 5 minutes or less. Next, the Orchestrator needs to be set to vSphere. TKG Extensions required two Pre-requisites tools (1) Kapp-controller (2) CertManager. Kubernetes provides only an ingress API, hence we deploy Contour for ingress controller. Reduce storage cost and complexity with VMware vSAN, enterprise-class storage virtualization software that provides the simplest path to hyperconverged infrastructure (HCI) and multi cloud. Similar to TKG, we need to setup a content library to pull from. Organizations might have standard mechanism to define namespaces according their defined standards. You can validate the object creation as following. Learn how your comment data is processed. In the example below, we create a 2Gi volume: Now we have a volume, we can create attach this to a pod. You can first verify the supervisor cluster member by using the following command: From vCenter, use the search field to look for supervisor. Leave SDN Integration set to None. Navigate to left side menu panel, click on the settings->Configuration->Data Sources. To store Tanzu Kubernetes release for use with Tanzu Kubernetes clusters, create a subscribed content library on the vCenter Server where vSphere with Tanzu is enabled. Getting started with Tanzu and NSX Advanced Load Balancer The NSX Advanced Load Balancer (NSX ALB) also known as AVI, provides a feature-rich and easy to manage load balancing solution. Then update the OS to use the new certificate (a reboot may be needed). Cert-manager adds certificates and certificate issuers as resource types in Kubernetes clusters and simplifies the process of obtaining, renewing, and using those certificates. Below we will go through the basic setup of HaProxy and enabling Workload Management to quickly get started. The networks in play here and where we'll see stuff being deployed are as follows: There's routing between these networks and also to the outside world. For more information on certificates, including creating a CSR, see the AVI documentation, https://avinetworks.com/docs/20.1/ssl-certificates/, Next, we need to create an IPAM Profile. Conveniently, there is a TKG Demo Appliance fling that we can leverage for our purposes. (Note that the terms TKC and TKG cluster are used interchangeably within this guide.). the issue with access Grafana web interface, https://reference.octant.dev/?path=/docs/docs-intro--page#getting-started, https://github.com/vmware-tanzu-experiments/vsphere-with-tanzu-proof-of-concept-samples, 2(a) NSX Advanced Load Balancer Configuration, https://kb.vmware.com/s/article/82049?lang=en_US, https://docs.vmware.com/en/VMware-vSphere/7.0/vmware-vsphere-with-tanzu/GUID-489A842E-1A74-4A94-BC7F-354BDB780751.html, Download the TKG Extensions v1.3.1 Bundle, Option 1: Patch or Edit the TKC manifest to add a default StorageClass. TKG Content Library. As a reminder, all ingress requests on our cluster will be served on Envoys LB IP address. This is hosted on GitHub: https://github.com/haproxytech/vmware-haproxy. Scaling out Tanzu Kubernetes Clusters involves changing the number of nodes. N.B. Browse an extensive library of production-ready open source software images. Contour.config.default.HTTPVersion : A default HTTPversion need to be used by Contour. Update the YAML file and re-apply secret & app YAML files, Ref: Supported Prometheus Configuration parameters can be found at VMware official Documents.

Resource monitoring is an important aspect of managing a Tanzu environment. Note: In case of not having a persistent storage class, we can create one and update the persistent storage class name in the Prometheus config file. From the permissions tab, you can add/remove/edit permissions for a particular namespace. Then on your jump VM, download the zip file vsphere-plugin.zip, either using a browser or via wget, pointing to https:///wcp/plugin/linux-amd64/vsphere-plugin.zip. Alternatively, you can also choose the tab Console on the same UI, which provides the events filtered by the query values. Navigate to Templates > Profiles > IPAM/DNS Profiles > create. In this guide we detail the two networking options available invSphere with Tanzu, namely vSphere or NSX-T networking. Provide the IP subnet, gateway, and IP address pool to be utilized. Many of the modern apps and tools implementing observability patterns like /metrics API on which Prometheus can scrape the metrics. In order to setup trust with vCenter, and to avoid skipping the TLS verify step on every login, we need to download the certificate bundle and copy the certificates to the appropriate location. Otherwise, download and install Octant, as described in the Octant getting started page:https://reference.octant.dev/?path=/docs/docs-intro--page#getting-started. Next, we create a Namespace and a new TKG cluster (see the section earlier in this guide). Contour is highly configurable ingress, providing various options to customize the contour deployment according to the customer environmental needs. Jun 6 - Kubernetes Choice with Guard Rails - What it Means for your Business. Access the e-Library OPAC system and click the "Login" button at upper right corner, enter your Library card number and password to log in. The Harbor login page should be seen: We can also test access using docker login. We identified four replicable distinct clusters of patients with AF: cluster I included diabetic patients with HF with preserved ejection fraction and chronic kidney disease; cluster II included elder patients with a low BMI and pulmonary hypertension; cluster III included patients with metabolic syndrome and atherosclerotic disease; and cluster IV included patients with left heart . Updae the YAML file and re-apply secret & app YAML files. Hunting the Bear: Why Agile Product Teams Have So Much Trouble (we must use Envoy version v1.17.3_vmware.1), Edit contour-data-values and tag the Envoy Image to version v1.17.3_vmware.1. Once the appliance has been deployed and powered on, login to the UI using the supplied management IP/FQDN. We could also use a script to add this line in to both files. First the CA cert, remember to update as needed: Then the Server Cert, updating the site name as needed: We will then need to copy the cert files to the appropriate directory: Run the following command to ingest the certificates: Convert the crt file for use by Docker and copy: Now, we must configure Harbor to use the certificate files: In the https section, update the certificate and private key lines to point to the correct files, for example: Wait for the services to start and logout of the CentOS VM. [Read more] Create, Secure, and Synchronize a Local Content Library for Tanzu Kubernetes releases Note: You should take a backup of current config entries before you delete, and can be restored once the new version has been installed. For permissions, leave Write selected, as this will allow for easier deployment and automation between ALB and vCenter. The approach demonstrated here uses the UNIX shell command read to take input from the keyboard and assign it to a variable named $PATCH. Some of these enhancements have been described in recent posts, such as the new v1alpha2 Tanzu Kubernetes Cluster format, as well as new capabilities to the Namespace Service. Here, we will push an image to the private repository and pull it into our TKG cluster. Kubernetes Ingress API has very limited features and might not serve the traffic routing and security needs of the DevOps team. vSphere Distributed Switch (defined and managed by vCenter), Setting up the network stack (will explore all three options for network stack), Creating SBPM policy and assignment them to Namespaces, Setting up a standalone Harbor Image repository, Creating a Tanzu Kubernetes Cluster (TKC aka guest cluster), Installing Tanzu Extensions (CertManager, Contour, Fluentbit, Prometheus, Grafana), Kapp-controller & CertManager (Pre-requisite, common tools). To create a tag-based VM storage policy, reference the documentation: https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.storage.doc/GUID-D025AA68-BF00-4FC2-9C7E-863E5787E743.html, Once a Policy has been created, navigate back to the namespace and click on add storage. Enabling Workload Management. This includes the Kubernetes cluster node network, container network, a load balancer for the control plane, a load balancer for workload apps, and layer-7 ingress for the workload apps. Here, we have created a block of 99 addresses in the workload network, from our /24 range: After the initial configuration, we will need to either import a certificate or create a self-signed certificate to be used in Supervisor cluster communication. For full instructions, please refer to the documentation, https://docs.vmware.com/en/VMware-vSphere/7.0/vmware-vsphere-with-tanzu/GUID-AC9A7044-6117-46BC-9950-5367813CD5C1.html. The library also holds one of the world's best collections of ancient Chinese texts. After you click next, youll need to accept the SSL thumbprint of the certificate by clicking the YES button. Note: At the time of this document preparation(vSphere 7.0u2), Supervisor Services (vSphere POD Services, built-in Imagerepo service, etc., )are available only when the stack is built withNSX-T SDN. However, vSphere with Tanzu also allows bringing your Load balancer, for example, HAProxy. May 25 - [EMEA] What's new with VMware Tanzu Application Platform. Create a Subscribed Content Library - VMware Docs Or Windows, using putty navigate to Connection > SSH > Tunnels on the left panel. Deploy Tanzu Kubernetes Grid (TKG) Clusters on vSphere 7 The following platform tools are shipped as part of the TKG Extensions bundle, TKG extensions package can be downloadable from my.vmware.com -> Product Downloads -> Go to Downloads -> VMware Tanzu Kubernetes Grid -> Go TO Downloads-> VMware Tanzu Kubernetes Grid Extension Manifests 1.3.1 -> Download Now. First, we switch contexts to the supervisor namespace: To ensure the local information is synchronised, re-issue a login (a logout is not needed). This is not a Kubernetes namespace, Tanzu Kubernetes Grid Cluster, an upstreamK8S cluster created for DevOps workloads. We will explore the necessary tooling like Fluentbit, Prometheus, Grafana which are already part of TKGExtensions package. (HaProxy will serve the IP from the workload subnet): Once deployed, we can list the external IP assigned to it using the get service command: Therefore, opening a browser to the External-IP on port 8080, i.e. Here are some of the default parameters: Port: 9000. Upgrade details located in the official documentation for Upgrading the vCenter Appliance. All ingress & HTTPProxy objects will have the same IP address, i.e. Note, in a production environment, a separate 'data network' for the SEs may be desired. To successfully deploy this app, we must either add a default storage policy into our TKC manifest or edit the manifests to define a storage policy. This must be within the CIDR range defined in step 3.1 of the HaProxy configuration, * These must not overlap with the load-balancer addresses. This is done by applying a manifest on the supervisor cluster which will define how the cluster is setup. Use the commands below to pull the KUARD image and assign an IP to it. Note: No need to change any default values unless the cluster doesnt have a default storage class (or) one wishes to use the specific storage class for Prometheus & AlertManager. Launch Octant simply by the command Octant: Open an SSH tunnel port 7777 of the jump host . On the VM Service card click on Add VM Class to add VM class definitions to the Namespace: This will bring up a window to enable you to add the relevant VM classes (or to create your own). If you want more background on VMware Tanzu, you can read more about it here. There are several methods to upgrading the vCenter appliance. This is determined by the operating system, in the case of the TKG Appliance / Photon OS, it is /etc/ssl/certs: Finally, either use an OS utility to update the system certificates, or reboot the system. Method 1: Edit the YAML file used for deployment and apply the file just as it was done to create the TKC. Below, we will briefly run through the steps to configure the NSX ALB. Scale storage capacity without adding hosts with VMware Cloud Flex Storage, the flexible, simple and cost-effective way to store and manage your data. For more information, see the Release Notes. Back in vCenter, create a new content library with the link provided: We then proceed to configure a namespace. At the time of writing, the latest version available is 20.1.5. VMware Application Catalog | VMware Tanzu Now we know the pod details contour and envoy, we can extract the logs for troubleshooting purpose.

Specify v1.17.3_vmware.1 in the configuration as shown. Quick Tip - Correctly naming TKR's in Local Content Library for vSphere If youre not familiar with Content libraries, you can think of them as a container registry, only for virtual machines. In order to get it scraped by Prometheus. This can then be combined with the login command for quicker/automated logins, for example (here we have also installed the certificates, thus we have a shorter login command): It is a good idea to get any manifest files checked for correct syntax, etc. VMware vSphere is a powerful virtualization platform that consolidates servers and optimizes resources for scalable and reliable application deployment. Once Cluster is up, you can check the status. will start the Kubernetes deployment wizard. Secrets: TLS key-value, needed only for HTTPS use case. Configuration NSX ALB; Enabling Workload Management. In the simplest configuration, the HA Proxy appliance will need a minimum of two interfaces, one on the Management network and the other on a Workload network, with a static IP address in each. First, we will need to change fullVersion parameter to null. Here we are using Secret from K8S standard API. Example with annotation applying to workloads. Access the Content Libraries page from the Menu. Abstract - National Center for Biotechnology Information See https://docs.vmware.com/en/VMware-vSphere/7.0/vmware-vsphere-with-tanzu/GUID-0F6E45C4-3CB1-4562-9370-686668519FCA.html. For the purposes of a PoC, a self-signed certificate should suffice. A: Object type. Envoy.hostPort.http : Port number for http requests , defaulted to 80, Envoy.hostPort.https: Port number for https requests, defaulted to 443, Namespace containing contour and its dependency objects/, Extract current config values from clusters, Download new version from the Tanzu Extensions package. pane to monitor the status of the update. Do not skip updates, such as from 1.16 to 1.18. You can then change contexts between the TKC and the supervisor namespace with the kubectl config command (as above). Note that both standard and consolidated deployments can be used. Note that the Control Pane cannot be scaled in. VMware provides powerful solutions for storing, protecting, and recovering data in the event of a disaster. Note that whilst the operations are in progress, there may be errors shown on this page, as it is monitoring a desired state model: Once the supervisor cluster has been configured, a namespace should be created in order to set permissions, storage policies, and capacity limitations among others. To delete Contour ingress, we shall need to delete the following objects, Extracting FluentBit data values configured on the cluster, Note: in K8S secretes are base64 encoded, hence we shall decode the secret values with base64 to make it readable for us, Read logs generated by FluentBit container running inside the pods. Since we already have host entry we can test the app with using Access https://foo.bar.com/foo using curl or Web-browser form you cli-vm, Since it is a self-signed certificate, we should accept the browsers security settings before we get to the page, Now let us check other subdomain https://foo.bar.com/bar using curl or Web-browser from theCLI-VM. First, switch to namespace where TKC lives. If the TKG Demo Appliance is being used, Octant is already installed. A: Object type. Which include, multi-team FQDN, TLS Delegation, inclusions, Rate-Limiting, Traffic-Shifting, Request-Rewriting, out of box integration with observability tools. CertManager: Most of the Kubernetes platform components need SSL certificates. Once a TKG cluster has been provisioned, developers will need sufficient permissions to deploy apps and services. Like other immutable architectural pattern, the best way to upgrade is to Delete the Contour and re-install the new Ingress. From our example, we see the guest cluster, the pod name simple pod and the PVC name given in the manifest: Clicking on Physical Placement shows (as we are using a vSAN store) the backing vSAN details: We can also see details of the PVC in vCenter under Cluster > Namespaces > Namespace > Storage > Persistent Volume Claims: Here, we can see more details specifically Kubernetes parameters, if we click on View YAML: The Kubernetes documentation has a practical example on using PVCs using WordPress and MySQL:https://kubernetes.io/docs/tutorials/stateful-application/mysql-wordpress-persistent-volume/. Note the values for the namespace, network, class name, image name, storage class, and hostname and adjust accordingly: Note: ensure that the base64 encoded data is indented. Why do we need a content library? The outline procedure for this is given in https://kb.vmware.com/s/article/2108294 with more details here, https://via.vmw.com/tanzu_tls. Note that a VM created through the VM Service can only be managed using kubectl: vSphere administrators can see the VM in vCenter, but cannot edit or otherwise alter the VM, but can display its details and monitor resources it uses. Deploying pods and deployments. In vCenter, ensure that DRS and HA are enabled for the cluster and a storage policy for the control plane VMs exists. Under the compute tab for the namespace, the resources for Tanzu Kubernetes as well as Virtual Machines display key information about the environment such as version, IP address, phase, etc. An example manifest is shown below, this will create a cluster in the ns01 supervisor namespace called tkgcluster1 consisting of one control-plane and three worker-nodes, with the Kubernetes version 1.17.8: Lets dissect this manifest to examine the components: A: These lines specify the API version and the kind, these should not be modified. Phone Consent. Then click on add and open a session to the jump host VM: Thus, if we open a browser to http://127.0.0.1:777 (note http not https) we can see the Octant console: VMware vSphere is the leading virtualization platform, enabling organizations to run, manage, and secure applications across cloud and on-premises environments with unmatched agility, scalability, and efficiency. The following IP addresses have been reserved for use: non-routable /22 subnet for pod networking, non-routable /24 subnet for Kubernetes services, two routable /27 subnets for ingress and egress, 5x consecutive IP addresses in the management range for Supervisor services. To obtain a subscription link, first sign in using your myvmware credentials. Moreover, this must cover the IP Address Ranges for Virtual Servers which will be used later to enable Workload Management in vCenter (see below). Review About Tanzu Kubernetes release Distributions. Required fields are marked *. Next, we can proceed to login to the supervisor namespace using kubectl vsphere login.
