feat(admin): add machine size update endpoint and admin UI by evanjacobson · Pull Request #1357 · Kilo-Org/cloud

evanjacobson · 2026-03-21T03:47:39Z

Summary

Adds a targeted PATCH /api/platform/machine-size endpoint to update a kiloclaw instance's machineSize without re-provisioning (which would wipe envVars, secrets, etc.)
Adds updateMachineSize DO method, internal client method, and tRPC admin mutation through the full stack
Adds Machine Size editor in the admin panel's Live Worker Status card with valid Fly.io machine configurations (shared-cpu-2x minimum, 3 GB RAM minimum)
Memory options are dynamically computed based on cpu_kind and CPU count, respecting Fly's step size and per-preset min/max rules
selection persists on redeploy

Test plan

Verify pnpm tsc --noEmit passes in both kiloclaw/ and root
Test the admin UI: open an instance detail, verify Machine Size displays correctly
Test editing: changing CPU Kind auto-adjusts CPU and memory options
Test Save: confirm mutation succeeds and toast shows "Takes effect on next restart"
Test Reset to Default: confirm sends null and displays "Default (shared-cpu-2x / 3 GB)"
Verify new size is applied after a machine restart (via guestFromSize)

Add a targeted PATCH endpoint to update a kiloclaw instance's machineSize without re-provisioning (which would wipe envVars, secrets, etc.). New size takes effect on the next machine restart. The admin UI presents valid Fly.io machine configurations with dynamic memory options based on cpu_kind and CPU count, enforcing shared-cpu-2x as the minimum preset and 3 GB as the minimum RAM.

…itivity

Instead of waiting for a restart, the "Save & Apply Now" button immediately reconfigures the Fly machine by fetching its current config and patching only the guest (CPU/memory) field. This preserves the running image (version pin), env vars, mounts, and all other config exactly as-is — equivalent to `fly machine update`. A secondary "Save for Restart" button retains the old behavior.

1. Cap memory picker presets at 16384 MB to match MachineSizeSchema max 2. Defer persisting machineSize until after successful Fly apply so a failed update doesn't leave stale size in storage 3. Handle stopped/created machines in applyNow by calling startMachine explicitly (matching restartMachineInBackground behavior) 4. Pass updated.instance_id to waitForState so it waits for the new machine version, not a stale pre-update started state

…troy Re-read status from storage after Fly API calls and bail if the instance was destroyed in the interim. Prevents persist() from recreating a partial row with only machineSize after finalizeDestroyIfComplete() has cleared all storage.

DurableObjectStorage.get() returns undefined (not null) for missing keys, so the strict === null check never matched after storage was cleared by finalizeDestroyIfComplete().

Main removed the trial_end logic from subscription_data in createSubscriptionCheckout. These tests were incorrectly kept during merge conflict resolution.

Seems like you got some unrelated changes in here

these never got generated previously but are now merged into main. When I update the branch they should disappear

RSO

There are changes here that don't belong, but other than that, the change looks good.

One thought: Is this tRPC call going through the main tRPC endpoint? Otherwise, we may have to bump the maxDuration of the endpoint.

@RSO @evanjacobson instead of adding endpoints - which we probably have to workaround/change when go to do multiple instance sizes. What if we just make the instance size a env var. Then you can just override it in .dev.vars if you want to provision something else?

The goal was to make this available in prod for our machines, in addition to dev @pandemicsyn
