The runs-on label

You point a job at Trunk Runners with one runs-on label.

runs-on: trunk=${{ github.run_id }}-${{ github.run_attempt }}

Options

Option	Required	What it sets
`size`	No	The machine size, which sets the CPU count. See Machine sizes.
`memory`	No	The memory per CPU: `low`, `standard`, or `high`. See Machine sizes.
`template`	No	The template (a prepared environment) for the job. See Templates.
`cache`	No	`trunk` or `github` to choose the cache for `actions/cache`. See Caching.

A large runner with high memory:

runs-on: trunk=${{ github.run_id }}-${{ github.run_attempt }}..size=large..memory=high

A large runner with low memory, for a job that needs CPUs but little memory:

runs-on: trunk=${{ github.run_id }}-${{ github.run_attempt }}..size=large..memory=low

A job on a chosen template:

runs-on: trunk=${{ github.run_id }}-${{ github.run_attempt }}..size=medium..template=<template-id>
