ConfigMap

Edit

ConfigMaps allow you to decouple configuration artifacts from image content to keep containerized applications portable. This page demonstrates how to create ConfigMaps and configure Pods using data stored in ConfigMaps.

Create a ConfigMap

Sign in with project-regular, enter into one project (e.g. demo-namespace), then select Configuration Center → ConfigMaps.

Create a ConfigMap

Step 1: Fill in the Basic Information

1.1. Click Create ConfigMap button, then fill in the basic information in the pop-up window. There are two ways to create a ConfigMap, i.e. fill in the creation table and edit mode. The following mainly introduces each step within creation table. If you prefer edit mode, you can click on the edit mode button, it supports the yaml and json formats. Edit mode makes it easy for users who are used to command operations.

Edit Mode

1.2. On the basic information page, enter the name of the ConfigMap, you can also fill in the description as required.

  • Name: A concise and clear name for this ConfigMap, which is convenient for users to browse and search.
  • Alias: Helps you better distinguish resources and supports Chinese.
  • Description: A brief introduction to ConfigMap.

Click Next when you're done.

Basic Information

Step 2: ConfigMap Settings

The key-value pairs data could be stored in ConfigMaps, which is used to set as container environment variables, or add the ConfigMap data to a volume, it could be used in workloads. The data as following example:

data:
  game.properties: 158 bytes
  ui.properties: 86 bytes

ConfigMap Settings

Using this ConfigMap

ConfigMaps can be mounted as data volumes or be exposed as environment variables to be used by a container in a pod.

  • In Volume, click on Reference Config Center, then select the created ConfigMap.
  • In the Environment Variables, click Reference Config Center then select the created key.
