Publishing new Kubernetes ConfigMaps or Secrets

You can use the Tooling for Apache Camel K extension to create ConfigMaps and Secrets and publish them to the running Kubernetes system.

Before you begin

You must have a *.properties file that you want to use as the basis for the ConfigMap or Secret. Properties files consist of name/value pairs. Each property can then be referenced in a route by the property name to use the value by reference.

For example, you might have an application.properties file that has two entries:

my.message=Hello World
logging.level.org.apache.camel=DEBUG

In your route, you can then refer to my.message by providing as ``.

In a Groovy route, that might look like from('timer:props?period=1s').log('').

Steps

1. In the VS Code Explorer view, right-click on the *.properties file.
2. Select one of the following options:
   • Create Kubernetes Config Map from File
   • Create Kubernetes Secret from File
3. Type the name of your new ConfigMap or Secret. The name must start with a letter and contain no spaces. You can use numbers or hyphens.
   • For example, my-config-map is a valid name but my config map is not.

   

4. Press Enter. The extension creates a new ConfigMap or Secret that you can reference in your Apache Camel K route.

For more information about configuration with ConfigMaps or Secrets, see Configuration via ConfigMap or Secret in the Apache Camel K documentation for more details.
