What is Oracle Verrazzano?<\/h2>\n\n\n\n
For an overview of Verrazzano, see our Oracle Verrazzano introduction page<\/a> and the following materials published by Oracle. Here’s a quick explanation.<\/p>\n\n\n\n The official name of Oracle Verrazzano is Verrazzano Enterprise Container Platform, which is provided as open source<\/a>. v1.0 was released in August 2021, and the latest version in August 2023 is v1.6. It is free to use, but we also offer paid commercial support called Oracle Verrazzano Premier.<\/p>\n\n\n\n The following diagram is an overview of Oracle Verrazzano. As you can see from this figure, we have combined a lot of open source components to achieve infrastructure operation management, monitoring functions, and security functions (SSO\/access management).<\/p>\n\n\n\n Verrazzano is described in the official documentation<\/a> as follows:<\/p>\n\n\n\n Verrazzano is an end-to-end enterprise container platform for deploying cloud native and traditional applications in multicloud environments. It is made up of a curated set of open source components \u2013 many that you may already use and trust, and some that were written specifically to pull together all of the pieces that make Verrazzano a cohesive and easy to use platform.<\/p>\n<\/blockquote>\n\n\n\n Similar commercial platforms include Red Hat OpenShift and VMware Tanzu.<\/p>\n\n\n\n It is difficult to understand Verrazzano even after this explanation, but to summarize the benefits from the perspective of “what you get out of it,” they are as follows:<\/p>\n\n\n\n * Heridon is a Java application framework developed by Oracle that is suitable for the development of MicroProfile-compliant microservices.<\/p>\n\n\n\n The following diagram shows the Verrazzano installation procedure. The key points are “Set up Kubernetes environment” and “Installing Verrazzano”.<\/p>\n\n\n\n Depending on the Kubernetes environment you use, the effort required to build and the hardware resources to prepare will vary greatly. In addition, the installation of Verrazzano is the main task, and Verrazzano is set up in the container environment of Kubernetes. Once that’s done, you’ll be able to deploy the container application.<\/p>\n\n\n\n The quick start<\/a> of the official manual assumes that a Kubernetes cluster is being built. Therefore, we will skip the method of building a Kubernetes cluster and introduce the following procedure as a method of installing Verrazzano.<\/p>\n\n\n\n However, when there is no Kubernetes cluster, it must be built beforehand.<\/p>\n\n\n\n As options to build a Kubernetes cluster, the Verrazzano manual introduces the following four types:<\/p>\n\n\n\n Within these, the easiest option is to use Oracle Cloud Infrastructure’s OKE<\/strong>. The build procedures are also introduced in various documents.<\/p>\n\n\n\n Oracle Cloud Native Environment<\/strong> is an open software suite for on-premises Kubernetes-centric container environments. In other words, it is a software set that achieves multifunctionality such as managed Kubernetes services on the on-premises server. It can be said that it is a Kubernetes distribution provided by Oracle.<\/p>\n\n\n\n Generic Kubernetes<\/strong> is so-called basic Kubernetes.<\/p>\n\n\n\n kind<\/strong> is a tool that uses Docker containers as worker nodes to configure Kubernetes clusters locally. You can build multi-node clusters that are not possible with a single node, such as Minikube.<\/p>\n\n\n\n So this time, we will build a Kubernetes cluster using the relatively simple kind, that can only be achieved on-premises.<\/p>\n\n\n\n Architecture diagram when configured with Oracle Cloud Native Environment and Verrazzano<\/strong><\/p>\n\n\n\n Check the prerequisites according to the purpose of use and the environment in which it is used.<\/p>\n\n\n\n Verrazzano offers three installation profiles<\/a> depending on the configuration used. In addition, the system requirements<\/a> describe the necessary hardware requirements for each. Ensure that the required resources are met, depending on the purpose of use.<\/p>\n\n\n\n Each version of Verrazzano supports a different version of Kubernetes. Therefore, check the version of Kubernetes supported by Verrazzano in Supported software versions<\/a>. The support status for v1.5 and v1.6 is shown in the table below.<\/p>\n\n\n\n As you will know if you are familiar with Kubernetes, the software related to Kubernetes is updated frequently. Please be sure to check the latest information. Also, if you have a good knowledge of Kubernetes and can resolve it on your own without following the manual, we recommend that you keep each up to date to the extent supported.<\/p>\n\n\n\n The Verrazzano manual uses Kubernetes version 1.21 for kind. This time it is for testing purposes, so use Verrazzano 1.5 and Kubernetes 1.21, the same as in the manual.<\/p>\n\n\n\n Since we could not proceed with the actual installation this time, we will explain how to install it in the next article.<\/p>\n\n\n\n\n
