Bridge Configuration

The bridge configuration includes:

• bridge: The name of the bridge

  Example: lambdo0

• ip: The IP address of the bridge

  Example: 10.0.50.0/8

Here is an example of the VMM configuration:

apiVersion: lambdo.io/v1alpha1
kind: Config
vmm:
  kernel: /var/lib/lambdo/kernel/vmlinux.bin

The VMM configuration includes:

• kernel: The path to the Linux kernel binary utilized by the VMM

  Example: /var/lib/lambdo/kernel/vmlinux.bin

Agent Configuration

Here is an example of the agent configuration:

apiVersion: lambdo.io/v1alpha1
kind: Config
agent: # NOT IMPLEMENTED
  path: /usr/local/bin/lambdo-agent
  config: /etc/lambdo/agent.yaml

The agent configuration includes:

• path: The path to the agent binary

  Example: /usr/local/bin/lambdo-agent

Language Runtime Configuration

Here is an example of the language runtime configuration:

apiVersion: lambdo.io/v1alpha1
kind: Config
languages:
  - name: NODE
    version: 12
    initramfs: /var/lib/lambdo/initramfs/node-12.img
    steps:
      - name: Run the code
        command: /usr/local/bin/node {{filename}}
        output:
          enabled: true
          debug: false

The configuration for a Node.js runtime includes:

• name: The name of the runtime

  Example: NODE

• version: The version of the runtime

  Example: 12

• initramfs: The path to the initramfs for the runtime

  Example: /var/lib/lambdo/initramfs/node-12.img

• steps: The steps to run the code. Each step includes the following parameters:
  • name: The name of the step

    Example: Run the code

  • command: The command to run for the step

    Example: /usr/local/bin/node {{filename}}

  • output: The output configuration for the step. This includes the following parameters:
    • enabled: Whether to enable the output

      Example: true

    • debug: Whether to enable debug output (useful for build steps)

      Example: false
