Usage overview

Use the Container runtime to run containers on Kubernetes. It exposes a Function of kind container and several task actions to run jobs, serve services, build images, or deploy workloads.

• job: Execute a container as a one-off job
• serve: Deploy a container as a long-lived service
• build: Create a Docker image with custom instructions
• deploy: Deploy an application workload

To execute a container workload on the platform:

1. Create a Function resource that references your container image and declares inputs/outputs and call function.run() to execute the workload.
