Multi-stage builds
Build tools stay out of the final image, in one readable Dockerfile.
DevOps
Docker development services for software that deploys the same way twice
Our fleet platform deploys with a Docker multi-stage build and Docker Compose. We package back ends as images and move older Compose V1 setups to the current CLI.

What we do with Docker
Compose deployments
One Compose file describes the services and starts them together.

Scripts moved from docker-compose to docker compose.
Back end images
FastAPI services on Python 3.13 packaged for deployment.

Compose V1
- Written in Python, run as docker-compose
- Compose files in the original format 1 do not run on newer versions
Supported
Compose v2 and v5
- Written in Go, run as docker compose with a space
- The top-level version element is ignored

When Docker is the right call
Pick Docker when
- You want the same build to run on a laptop and on a server
- A few services must start together
- Your deployment today is a list of manual steps
Look elsewhere when
- You run dozens of services across many hosts, where we would look at Kubernetes, which we have no published build on
- The product is a static site on a managed host
- You need a published Compose V1 migration to inspect, which we do not have

What buyers ask first
What is a multi-stage build?
A Dockerfile with several FROM statements. Each starts a new stage, and the final image copies in only the artifacts it needs, so build tools and intermediate files stay out of it.
Is docker-compose still supported?
No. Docker supports Compose v2 and v5, which run as docker compose with a space. The old hyphenated docker-compose was Compose V1.
Docker or Kubernetes?
Our published deployment is Docker with Compose. We have no published Kubernetes build, and we say so on the first call.
Who owns the code and the cloud accounts?
You do, from the first commit. Repositories and cloud accounts stay in your name.
