Label Reference

StarSling uses structured labels to specify runner configuration. The numeric suffix on each label indicates the vCPU count (e.g. -8 = 8 vCPU). The label without a suffix is the 4 vCPU default.

StarSling Labels

Label	OS	vCPU	Memory	Price per minute
`starsling-ubuntu-24.04-2`	Ubuntu 24.04	2	8 GB	$0.004
`starsling-ubuntu-24.04`	Ubuntu 24.04	4	16 GB	$0.008
`starsling-ubuntu-24.04-8`	Ubuntu 24.04	8	32 GB	$0.016
`starsling-ubuntu-24.04-16`	Ubuntu 24.04	16	64 GB	$0.032
`starsling-ubuntu-24.04-32`	Ubuntu 24.04	32	128 GB	$0.064
`starsling-ubuntu-24.04-64`	Ubuntu 24.04	64	256 GB	$0.128

GitHub Label Mapping

The default starsling-ubuntu-24.04 (4 vCPU / 16 GB) replaces these GitHub-hosted runner labels:

GitHub-hosted Label	StarSling Label
`ubuntu-latest`	`starsling-ubuntu-24.04`
`ubuntu-24.04`	`starsling-ubuntu-24.04`

For larger workloads, opt into a bigger size by appending the vCPU suffix (e.g. starsling-ubuntu-24.04-8). For cost-sensitive or lightweight jobs, use the 2 vCPU starsling-ubuntu-24.04-2 label.

Examples

Basic Usage

jobs:

Drop-in Replacement

jobs:
  build:

Invalid Labels

These will fail to match a runner:

Invalid Label	Reason
`starsling-ubuntu-22.04`	Only Ubuntu 24.04 is supported
`starsling/ubuntu-24.04`	Use hyphens, not slashes
`starsling-ubuntu-latest`	Use `starsling-ubuntu-24.04`
