Containers that build fast and run small.

Multi-stage Dockerfiles, docker-compose for a local dev loop people don't dread, BuildKit and layer caching that take CI builds from minutes to seconds, and image scanning on minimal base images. The kind of setup where a build is something you stop noticing.

A build you stop watching, an image you stop worrying about.
01The idea

A 15-minute build is a tax you pay on every push.

Most slow, bloated Docker setups grew by accretion — a layer added here, a dependency reinstalled there, a base image nobody chose on purpose. The result is a build that reinstalls the world on every commit, an image that ships its own compilers, and a local dev loop people quietly avoid. We rebuild it deliberately: multi-stage Dockerfiles that keep build tools out of what you ship, layer and BuildKit caching so unchanged work is reused, a compose setup that makes local dev quick, and scanning on a minimal base. The goal isn't a clever Dockerfile. It's a build nobody has to wait for.

02The signs

Every push shouldn't cost you a coffee break.

Each familiar symptom has the same answer — a build done deliberately.

  • 01

    Builds take fifteen minutes a push

    Layer and BuildKit caching so only what changed gets rebuilt.

  • 02

    Images are hundreds of megabytes

    Multi-stage builds on a minimal base — runtime only, no build tools.

  • 03

    Local dev with Docker is painful

    A compose setup with hot reload that comes up in one command.

  • 04

    Nobody knows what's in the image

    A scanned, minimal base with a Dockerfile that's actually readable.

  • 05

    Dev works but prod breaks

    The same image everywhere, differing only by injected config.

03What we build

Everything a fast, lean build needs.

Tuned for the stack you actually run — not a generic template dropped in.

Multi-stage Dockerfiles
01

Multi-stage Dockerfiles

Build tools stay in an early stage; the final image carries only your app and its runtime.

BuildKit & cache tuning

BuildKit & cache tuning

Layers ordered and cached so CI reuses earlier work instead of rebuilding the world.

Minimal base images
04

Minimal base images

Distroless or Alpine where it fits — smaller pulls, faster deploys, less to attack.

Image security scanning

Image security scanning

Every image checked for known CVEs before it ships, with the policy you set.

04The pipeline

From source to a scanned image, the same way every time.

  1. Build01
  2. Cache02
  3. Scan03
  4. Compose04
  5. Ship05

Every build runs the same path — staged so build tools stay out of the result, cached so unchanged layers are reused, scanned for known vulnerabilities, shaped the same as your compose dev image, and shipped lean.

05Multi-stage builds

Build tools stay out of what you ship.

We split building from running. An early stage installs everything needed to compile or bundle your app; a clean final stage copies in only the finished artifact and the runtime to serve it. No compilers, no dev dependencies, no caches ride along — so the image is smaller, faster to pull, and has far less to attack.

  • Build stage and runtime stage, cleanly separated
  • Final image carries app and runtime only
  • No dev dependencies or build caches shipped
  • One readable Dockerfile, not a maze

06Local dev with compose

A local loop people don't dread.

When local dev is slow, every developer pays for it every day. We build a docker-compose setup that brings the whole stack up in one command, mounts your source as volumes, and wires hot reload so changes show without rebuilding. Clone the repo, run one command, and the full app — database, services, the lot — is running in minutes.

  • The whole stack up with one command
  • Hot reload — no rebuild to see a change
  • Source mounted as volumes
  • Dev built from the same image as prod
07Caching & build speed

From fifteen minutes to seconds.

Slow builds reinstall the world on every push because layers are ordered badly and nothing is cached. We put dependencies before your code so editing a file doesn't invalidate them, turn on BuildKit, and add a registry or runner cache so even a fresh CI runner reuses earlier work — running independent stages in parallel where they apply.

  • Layers ordered so deps cache cleanly
  • BuildKit enabled for faster builds
  • Registry / runner cache reused in CI
  • Parallel stages where they fit

08Security & minimal base

Scanned images, minimal surface.

A smaller image is also a safer one. We move to a minimal base — distroless or Alpine where it fits — run the app as a non-root user, and add image scanning to the build so every image is checked for known CVEs before it ships. Where it helps, we generate an SBOM so you know exactly what's inside.

  • Minimal base — distroless / Alpine
  • Image scan gates the build (Trivy / Grype)
  • Runs as a non-root user
  • SBOM so you know what's inside

09How we work

Fast builds, built deliberately.

01

Map what you build

We review your Dockerfiles, images, compose setup, and CI — and time the builds that hurt most.

02

Restructure the Dockerfiles

Multi-stage builds on a minimal base, with layers ordered so caching actually works.

03

Fix the local loop

A docker-compose setup with hot reload and volumes that comes up in one command.

04

Speed up CI

BuildKit, a registry or runner cache, and parallel stages so builds reuse earlier work.

05

Scan & hand off

Image scanning wired into the build, a non-root minimal base, docs, and a setup your team owns.

10Right when

The build has become the slowest part of shipping.

  • Your builds take 15 minutes

    Every push reinstalls the world because nothing caches — so the build is a tax on shipping.

  • Local dev with Docker is painful

    Spinning up the stack takes an afternoon and the loop is slow enough that people avoid it.

  • Image sizes are bloated

    Hundreds of megabytes shipping compilers and dev dependencies that production never calls.

12Questions

The things teams ask first.

Almost always, and usually by a lot. A 15-minute build is rarely the work itself — it's reinstalling dependencies on every push because nothing is cached, copying the whole repo before the parts that change, and reaching the network when it doesn't need to. We restructure the Dockerfile so the slow, stable layers (base image, system packages, dependencies) cache cleanly and only your code triggers a rebuild, then turn on BuildKit and a CI cache so even a fresh runner reuses earlier work. Builds that took 15 minutes commonly land in two or three.

Make the build the fast part.

Tell us where your Docker setup hurts — the slow build, the painful local loop, the bloated image. We'll restructure the Dockerfiles, fix the dev experience, tune the caching, and scan what ships, so a build stops being something you wait for.
