Creating an Application and a Model

This section describes how to use COC to quickly manage your resources and applications on the application and resource management page, including synchronizing resources, creating applications and modeling, and performing operations on a UniAgent. The procedure is as follows:

  1. Preparations: Sign up for a HUAWEI ID, complete real-name authentication, and enable COC.
  2. Synchronize resources. Obtain resources in all regions to which the current user belongs and synchronize the resources to COC.
  3. Create an application and model the associations between the application and resources. This feature facilitates resource management by service logic unit.
  4. Perform operations on a UniAgent. Install, upgrade, and uninstall a UniAgent on the corresponding node.

Preparations

  1. Sign up for a HUAWEI ID and complete real-name authentication.

    Before using COC, sign up for a HUAWEI ID, enable Huawei Cloud services, and complete real-name authentication.

    If you already have enabled Huawei Cloud services and completed real-name authentication, skip this step.

  2. Enable COC.

    Upon your first login, enable COC first.

    If you have enabled COC, skip this step.

Synchronizing Resources

  1. Log in to COC.
  2. In the navigation pane, choose Resources > Application and Resource Management. On the displayed page, click the Resources tab and click to synchronize resources.

  4. On the displayed Install UniAgent page, specify required information and click OK to trigger the automated installation process. Wait until the installation is complete.

    Figure 7 Setting parameters

    When installing a UniAgent for ECSs in the same VPC, you need to manually install a UniAgent for the first ECS and set this ECS as the installation node. For details, see Installing a UniAgent for the First Time.
