The evolution of the Depot Metal autoscaler

We announced Depot Metal, our new compute platform, back in July. We'd been working on it well before that, long enough that it has already been rewritten once in its not-so-long life. In this post,

Cansado de tener que ir la web de Depot cada vez que quería ver como iba el CI de mis proyectos, creé DepotBar: una app para macOS que permite ver rápidamente en el menu bar el estado de los últimos 5 workflows, usando Depot CLI under the hood: github.com/facmartoni/DepotB…

How we load tested Depot Metal before scaling up

We've recently been working on moving more GitHub Actions jobs onto Depot Metal so they can take advantage of the improvements in the new platform. Before moving traffic over, we needed to understand

Yes we are using depot after github actions kept going down. It has been more reliable.

multi-platform docker builds are slow mostly because of qemu emulation. depot runs native amd64 and arm64 builders instead. wito shows a build drop from ~30 minutes to 16 seconds. piped.video/UEACT6c3sm4?si=b9uF…

GitHub Actions without GitHub

At Depot, we hate a slow iteration loop. We will go to any lengths necessary to optimize a build, and we frankly get a bit nerd-sniped with opportunities to shave seconds off our customers' CI

I cut it down even more. ~12 minutes to lint, build, test, and publish 168 variations of PHP images 🚀 I'd call that a huge win! Thanks @depotdev!

the github control plane goes down and your jobs never dispatch, so all your ci redundancy is moot. luke walked through how depot ci runs github actions workflows without it, keeping runs alive through outages. depot.dev/blog/github-action…

GitHub Actions without GitHub

Depot CI runs GitHub Actions workflows without GitHub’s control plane, keeping CI online during outages and making workflows portable to new forges like Origin.

we had some fun and built a benchmark that computes the 20th fibonacci number by running each of its 18 steps in its own ci runner. each step takes about a second, so what you're really watching is the runner start up. depot.dev/blog/the-fibonacci…

the whole reason we reimplemented lvm: its volume-group lock is held ~100ms per op. we launch microvms up to 200 times a second in parallel, and that single lock, not the data path, is what breaks the latency target. depot.dev/blog/why-i-reimple…

Why I reimplemented LVM (with worse guarantees)

Our microVMs launch in under a second, and assembling their block devices in parallel put LVM's roughly 100ms volume group-wide lock directly in the critical path. We kept the kernel's device-mapper,...

delegation does not transfer ownership. an agent can write the change, but you still own how the system behaves in production. so iris keeps the parts that build context: planning decisions, close review, a limit on parallel work. depot.dev/blog/delegating-wo…

How I delegate the work, not my judgment

Agents can investigate, plan, and implement faster than I can, but reading a final diff is not the same as understanding why the system works the way it does. I own how the system behaves in produc...

a container can build in seconds and still crawl on deploy, because every node pulls and decompresses gigabytes it never reads to boot. soci fetches only the bytes needed to start. the index gets written at build time. depot.dev/blog/why-soci-belo…

Why SOCI belongs in the build

Most of a large container's startup goes to pulling and decompressing files it never reads to boot. SOCI makes the image seekable so the runtime loads only the bytes it needs, and Depot writes that...
