“Works on my machine” problems
Developers, CI and servers run the same image, so environment differences stop causing bugs that only appear after deployment.

Hire Docker developers who keep images small and builds repeatable
Getting an app to run in a container takes an afternoon. Getting images that build in seconds, contain no secrets, and behave the same on a laptop and a server takes engineers who work with Docker daily.
What is Docker?
When you hire Docker developers, you get engineers who package applications into Docker images: a single, versioned artifact holding the code, runtime and system libraries the app needs. Docker builds those images from a Dockerfile, runs them as isolated containers on any Linux host, and Docker Compose defines multi-container setups such as an app, database and cache in one file. The skill lies in images that are small, secure, cache-friendly and identical from development to production.
Where Docker solves a real problem
Multi-service applications
An app with a database, cache, worker and search engine starts with one Compose command instead of a page of setup instructions.
Repeatable deployments and rollbacks
Each release is an immutable, tagged image, so rolling back means running the previous tag rather than reversing manual changes.
Odoo and Python environments
Odoo versions, Python dependencies and system libraries such as wkhtmltopdf pinned per project, so several versions coexist on one host.
When we recommend something else
- A standard WordPress site on managed hosting — the host already handles the runtime, and containers add little.
- Fully serverless or platform-managed apps where the provider builds and runs the code for you.
- Desktop or GUI applications that need direct access to the user's display and hardware.
- A team with no one to own image updates — containers still need base-image patching, just in a different place.
What our Docker engineers deliver
Production Dockerfiles
Multi-stage builds, slim or distroless base images, non-root users, health checks and layer ordering that keeps cache hits high.
Compose environments
Local development stacks with hot reload and seeded data, and production Compose files for single-server deployments.
Build and registry pipelines
BuildKit and Buildx builds in CI, multi-architecture images for amd64 and arm64, tagged and pushed to a private registry.
Image security and hygiene
Vulnerability scanning with Trivy or Docker Scout, secrets passed at build time without baking them into layers, and retention rules for old tags.
From Dockerfile to running container
L1
Source and Dockerfile
Application code with a Dockerfile and .dockerignore kept in the same repository and reviewed like code.
L2
Build stage
BuildKit compiles dependencies and assets in builder stages, then copies only the runtime output into a small final image.
L3
Scan and sign
CI scans the image for known vulnerabilities and fails the build on policy violations before it is published.
L4
Registry
Tagged images stored in GitHub Container Registry, Amazon ECR, Docker Hub or a self-hosted registry.
L5
Runtime
Containers run under Docker Engine with Compose on a server, or are handed to Kubernetes or a managed container service.

What well-built images give your team
Faster builds
Ordering layers from least to most frequently changed, plus cache mounts, means most builds reuse earlier work.
Smaller attack surface
Minimal base images and non-root users leave fewer packages to patch and less for an attacker to use.
Parity across environments
The image tested in CI is the exact artifact that runs in production, byte for byte.
Easier onboarding
A new developer clones the repository and runs one command to get a working stack.
Docker Compose or Kubernetes?
| Consideration | Docker Compose | Kubernetes |
|---|---|---|
| Servers | One host | A cluster of nodes |
| Failover | Restart policies on the same machine | Rescheduling onto healthy nodes |
| Scaling | Manual, within one server's capacity | Horizontal autoscaling of pods and nodes |
| Operational effort | Low; a Linux admin can own it | Significant; needs dedicated platform skills |
| Good fit | Internal tools, Odoo for one company, staging environments | Many services, variable traffic, strict availability needs |

Docker questions
What does a Docker developer do?
A Docker developer writes and maintains the Dockerfiles, Compose files and build pipelines that package applications into container images. They also keep images small and patched, manage registries, and make sure containers behave the same in development, testing and production.
What is the difference between this page and your containerization service?
This page covers Docker as a technology and the engineering skills we bring to it. Our Docker containerization service is the defined project of taking an existing application, containerizing it and moving it to a container-based deployment.
Do we need Kubernetes if we use Docker?
No. Many applications run well on one server with Docker Compose, restart policies and good backups. Kubernetes becomes worth its complexity when you run many services, need failover across machines, or have traffic that varies enough to require autoscaling.
Is Docker free for commercial use?
Docker Engine and Docker Compose on Linux are open source and free to use. Docker Desktop requires a paid subscription for larger organizations under Docker's terms, so companies over its size thresholds should check licensing or use alternatives such as Podman or Linux-based development environments.
Can Odoo run in Docker?
Yes. Odoo runs well in Docker, with the Odoo image, a PostgreSQL container or managed database, persistent volumes for the filestore, and custom modules mounted or built into the image. The database and filestore need proper backups outside the container.
How do you keep Docker images secure?
We start from minimal, maintained base images, run as a non-root user, never bake secrets into layers, scan every build for known vulnerabilities, and rebuild regularly so security patches in base images actually reach production.
