🔮 Next up: starlark-gen
A CLI that reads OpenAPI specs and CRDs, then generates typed Starlark schemas automatically.
load("upbound-azure:v1/storage.star", "Account")
account = Account(location="westeurope")
Typo? Caught. Wrong type? Caught. Before kubectl apply.
#crossplane #platformengineering
🛡️ New in function-starlark: schema validation.
NetworkRules = schema("NetworkRules",
action=field(type="string", enum=["Allow","Deny"]),
)
Wrong types, missing fields, typos with did-you-mean — caught before Resource() runs. Fully opt-in.
#crossplane #platformengineering
🛠️ function-starlark progress:
-> Full feature parity with function-kcl
-> depends_on with creation sequencing
-> OCI module distribution
-> Metrics built in
-> Bytecode caching for sub-ms execution
From sidequest to something real. Still in dev, but the bones are solid.
#crossplane #opensource
🐍 What if Crossplane compositions read like Python?
region = get(oxr, "spec.region", "us-east-1")
Resource("bucket", body, depends_on=[db])
No new DSL. No Go template spaghetti. No 500MB runtime.
Starlark — Python syntax, Go speed, hermetic sandbox.
#crossplane #starlark
🔗 Crossplane Issue #2072 asked for resource dependency ordering. Closed as not_planned.
function-starlark just solves it:
Resource("app", body, depends_on=[db])
Deploys in order. Deletes in reverse. Usage resources created automatically. No manual state tracking.
#crossplane #platformengineering
Sidequest continues:
⚡ function-starlark benchmark:
-> 7.4x faster than function-kcl at 50 resources
-> 7.4 MiB idle memory
-> 82 MB image
Starlark compiles to bytecode once, writes directly to protobuf. No YAML roundtrip. No heavy runtime.

🐿️ Sidequest alert.
Building a custom Crossplane composition function that lets you write your logic in Starlark.
The gap I see? Nothing out there combines Python-like simplicity with Go template speed.
So I'm making one.

Blind automation becomes a threat when enough is at stake.
Kausality adds a causal dimension to Kubernetes controller hierarchies — the who and the why behind every mutation.

In this email, I just wanted to make a heads-up about Crossplane, a technology that solves a real and important problem that the majority of us suffer from every day:
👉🏼 Not owning our infrastructure.
