Chapter 1. Getting started with functions

Procedure

1. Create a function project by running the following command:

   $ kn func create -l <runtime> -t <template> <path>

   You get an output similar to the following example command:

   $ kn func create -l typescript -t cloudevents examplefunc

   You get an output similar to the following example:

   Created typescript function in /home/user/demo/examplefunc

2. Navigate to the function project directory by running the following command:

   You get an output similar to the following example command:

   $ cd examplefunc

3. Build and run the function locally by running the following command:

   You get an output similar to the following example command:

   $ kn func run

4. Deploy the function to your cluster by running the following command:

   $ kn func deploy

   You get an output similar to the following example:

   Function deployed at: http://func.example.com

5. Call the function by running the following command:

   $ kn func invoke

   This invokes either a locally or remotely running function. If both are running, the local one is invoked.
