Chapter 3. Running functions locally

You can use the kn func run command to run a function locally in the current directory or in the directory specified by the --path flag. If the function that you are running has never previously been built, or if the project files have been modified since the last time it was built, the kn func run command builds the function before running it by default.

kn func run

$ kn func run

kn func run --path=<directory_path>

$ kn func run --path=<directory_path>

You can also force a rebuild of an existing image before running the function, even if there have been no changes to the project files, by using the --build flag:

kn func run --build

$ kn func run --build

If you set the build flag as false, this disables building of the image, and runs the function using the previously built image:

kn func run --build=false

$ kn func run --build=false

You can use the help command to learn more about kn func run command options:

kn func help run

$ kn func help run
