Installation

Features

This plugin support several commands for interacting with Kubeless and Kubernetes. For executing them open the Command Palette (⇧⌘P (Windows, Linux Ctrl+Shift+P)) and type:

• Deploy Function: Deploy the current file as a Kubeless function
• Call Function: Call the current function
• Get Function Logs: Display the logs of the current function
• Delete Function: Delete the current function

Configuring Function Properties

After executing one of the above command a file is created under PROJECT_WORKSPACE/.vscode/funcs.json. This file includes the properties of a function regarding a specific file. For example:

[
  {
    "id": "hello",
    "handler": "handler.hello",
    "fileName": "/home/examples/get-python/handler.py",
    "runtime": "python2.7",
    "deps": null,
    "text": "def hello():\n    return \"hello world\"\n",
    "namespace": "default",
    "events": [
      {
        "type": "http",
        "path": "/",
        "hostname": null,
        "trigger": null
      }
    ],
    "environment": {},
    "memorySize": null
  }
]

You can modify some of these parameters to change the deployment of the function:

• ID: Function ID
• Handler: Identifies the function exported in the file. In this example we are exposing the function hello of the file handler.py.
• Runtime: Runtime to use for running the function.
• Deps: Dependencies of the function. This field is automatically refreshed each time a command is executed.
• Text: Function text. This field is automatically refreshed each time a command is executed.
• Namespace: Kubernetes namespace in which the function should be deployed.
• Events: Events that should trigger the function execution.
  • Type: http or trigger. If http is chosen the code will be trigger with HTTP GET/POST calls. In the case of using trigger the function will be executed when some message is published under certain topic.
  • Hostname: (Only for http type) Hostname in which the function should be deployed.
  • Path: (Only for http type) Subpath in which the function should be deployed.
  • Trigger: (Only for trigger type) Trigger topic.
• Environment: Key/Value for Environment variables that the function should have available.
• Memory Size: Maximum memory size to use for the function. F.e. '128Mi'
