The capsules repo is a collection of spaces capsule build rules. It builds and publishes spaces capsules as packages on github.
You can use these pre-built packages in your workspace using:
load("//@star/sdk/star/oras.star", "oras_add_platform_archive")
oras_add_platform_archive(
"ruby-v3", # This is the build rule name, can be anything
url = "ghcr.io/work-spaces", # Use ghcr.io/<github organization name>
artifact = "ruby-lang.org-ruby-ruby", # package artifact (without the `-platform`)
tag = "3.4.1-66a9004f" # package tag
)
