Create a managed registry

The microservices engine supports hosting the Nacos registry, which creates a new NacOS-type registry from scratch in the microservices governance Center and can be fully managed through the microservices Governance Center. The managed registry supports more operations than Integrated Registry, including viewing the basic information of the registry instance, microservice namespace management, microservice list, microservice configuration list, monitoring alerts, log viewing, plug-in center, and more.

Note

  • Install the skoala-init component in the ** skoala-system ** namespace of the target cluster. For details, see Manage Helm App.
  • If the selected group does not have a ** skoala-system ** namespace, refer to Create Namespace to create a namespace named ** skoala-system **.

The steps to create a managed registry are as follows.

  1. Click Microservice Governance-> Managed Registryin the left navigation bar, and then click Create Managed Registry in the upper right corner of the page to enter the page for creating the hosting registry instance.

  2. Enter the configuration information.

    What should be noted is:

    • Registry name: Letters, numbers, and delimiters (-) are supported. The registry name cannot be changed after it is created.

    • Deployment location: The system automatically verifies whether the skoala-init component is installed in the skoala-system namespace of the selected group.

      • If it is not installed, the registry cannot be created. Follow the prompts on the page to install the component.
      • The deployment location cannot be changed after the registry is created.

    • Resource configuration: You can directly set 1Core2G, 2Core4G, or customize the resource quota.

      • 1Core2G indicates that the request value and limit value of CPU are 2 cores respectively, the request value and limit value of memory are 2 G respectively, and so on.

      • Click Resource Advice to see throughput (TPS) for mainstream specifications such as 2 Core 4 GiB, 4 Core 8 GiB, and 8 Core 16 GiB.

    • Access mode: If NodePort is selected, the registry can be accessed externally through ** Service port + destination port **. If Internal Access is selected, the registry can be accessed through service ports only in the cluster where the registry resides. The default service port is 8848.

    • Deployment mode: If high availability mode is selected, the number of nodes must be at least three. In the production environment, the High Availability mode is recommended.

    • Data persistence: External storage is recommended.

      • No external storage is used: The data is stored in the Pod file system where Nacos resides. Data is lost after the Pod restarts, so external storage is recommended.

      • Using the database: Enter the name, address, port, username, and password of the database

      • Using a storage pool: Select an existing storage pool in the registry cluster and configure the storage capacity.

  3. At the bottom of the page click OK.

    If the operation is correct, a message indicating that the registry is created successfully is displayed in the upper right corner of the page. The Managed Registry List page displays the new registry instance.

Info

  • A new registry takes a period of time to initialize and is in the "Starting" state. After the initialization, the system enters the Running state.
  • You can click the registry name to view basic information such as the cluster/namespace, running status, resource quota, service port, storage configuration, and node list.
