Managing Configuration Items

Prerequisites

1. A CCE cluster has been bound to the environment. For details, see Binding a CCE Cluster.
2. The namespace to which the configuration item belongs has been created. For details, see Creating a Namespace.

Creating a Configuration Item

1. Log in to ServiceStage.
2. On the Environment Management page, click the target environment.
3. In the Resources area, choose Clusters from Compute.
4. Click Configuration Item > Create Configuration Item.
   ServiceStage allows you to create configuration items in Visualization or YAML mode.

   • Method 1: Visualization
     Configure the configuration item by referring to Table 1. Parameters marked with an asterisk (*) are mandatory.

     Table 1 Parameters for creating a configuration item in visualization mode

     Parameter	Description
     *Configuration Name	Configuration item name, which must be unique in a namespace. Enter 4 to 24 characters. Start with a lowercase letter and end with a lowercase letter or digit. Only use lowercase letters, digits, and hyphens (-).
     *Cluster	Cluster where the configuration item will be used.
     *Namespace	Namespace to which the configuration item belongs.
     Description	Configuration item description. Enter 0 to 255 characters.
     Configuration Data	Configuration data to be used in applications or used to store configuration data. Key indicates a file name, and Value indicates the content in the file. Click Add Data. Enter the key and value. The key contains 1 to 63 characters. Only use digits, letters, dots (.), hyphens (-), and underscores (_). The value contains 0 to 1,048,576 characters.
     Configuration Labels	Labels that you want to attach to various objects (such as applications, nodes, and services) in the form of key-value pairs. Labels define the identifiable attributes of these objects and are used to manage and select the objects. Click Add. Enter the key and value. The key contains 1 to 63 characters. Start and end with a letter or digit. Only use digits, letters, dots (.), hyphens (-), underscores (_), and slashes (/). The value contains 1 to 63 characters. Start and end with a letter or digit.

   • Method 2: YAML
     

     To create a configuration item by uploading a file, ensure that a configuration item resource file in YAML format has been created and the file size is less than 1 MB. For details, see Requirements for the Configuration Item Resource File.

     1. Select a cluster from the Cluster drop-down list.
     2. Use either of the following methods to set the configuration item resource file:
        • Click Upload File, select the configuration item resource file created locally, click Open, and wait until the file is uploaded.
        • Write or modify the ConfigMap resource file in Orchestration content.

5. Click Create ConfigMap.

   After the configuration item is created, it is displayed in the configuration item list.

Follow-Up Operations

After a configuration item is created, you can search for, view, update, and delete the configuration item by referring to Table 2.

• Deleted items cannot be restored. Exercise caution when performing this operation.
• The configuration item list contains system configuration items, which can only be viewed and cannot be modified or deleted.

Requirements for the Configuration Item Resource File

A configuration item resource file should be in YAML format, and the file size cannot exceed 1 MB.

Example:

apiVersion: v1
data: {}
kind: ConfigMap
metadata:
  annotations:
    description: ''
  labels: {}
  name: configmap-ww8qkl
  namespace: cse
