Docker and Containerisation Services
Run the same software the same way, everywhere.
Docker packages an application and everything it needs into a container, so it runs the same on a laptop, a test server and production. NetOfficials offers Docker and containerisation services for B2B clients: containerising existing applications, building images, local environments and the pipelines that ship them. When many containers must run together, see our Kubernetes services.

What We Build With Docker
Containers touch the whole path from a developer's machine to production. These are the main pieces.
Application Images
Dockerfiles that build small, repeatable images for each service.
Local Dev Environments
One command starts the app, database and queue so new developers are productive quickly.
Multi-Service Setups
Compose files that wire a web app, worker and database together.
Build Pipelines
Images built, tested and pushed to a registry on every change.
Image Hardening
Minimal base images, non-root users and vulnerability scans in the build.
Legacy App Packaging
Wrap an older application in a container so it can move to modern hosting.
When to Choose Docker
Docker pays off when environments differ, releases are fragile or onboarding is slow.
-
Engineering teams
It works on my machine, but not on yours
Different setups cause bugs that only appear in test or production.
- Same image from laptop to server
- Pinned runtime versions
- Fewer environment surprises
-
Companies planning to scale
A move to orchestration
You expect to run many containers and want a clean base before adopting Kubernetes.
- Services split sensibly
- Images ready for an orchestrator
- Health checks added
-
Teams with ageing applications
An old app that is hard to deploy
Installing it takes a long manual checklist that only one person knows.
- Dependencies written down in code
- Repeatable deployments
- Easier move to the cloud
Containers or Virtual Machines?
Both isolate workloads. Containers share the host's operating system kernel, while virtual machines each run a full operating system. The right mix depends on your workload.
Containers are usually the better choice when
- You release often and want fast, repeatable deploys
- You run many small services side by side
- You want identical environments for every developer
- You plan to adopt an orchestrator later
| Consideration | Docker containers | Virtual machines |
|---|---|---|
| Start-up and size | Light and quick to start | Heavier, with a full operating system |
| Isolation strength | Shared kernel, lighter isolation | Stronger separation per workload |
| Repeatable environments | Defined in a Dockerfile | Needs image or configuration tooling |
| Running different operating systems | Limited to the host kernel family | Any guest operating system |
| Packing many workloads on a server | Efficient use of resources | More overhead per workload |
| Best for | Modern services and frequent releases | Strong isolation or varied operating systems |
How We Deliver Your Containers
Every project moves from a written scope to agreed review points, so you always know what is happening and what comes next.
Inventory the Application
We list the services, dependencies, configuration and data your application needs to run.
Container planWrite the Images
Dockerfiles are written with pinned versions, small base images and sensible layer order.
Reproducible buildsCompose the Environment
Services, networks and volumes are defined so the whole system starts from one file.
Local stack runningAutomate the Pipeline
Builds, tests, scans and pushes to a registry are wired into your CI system.
Images built on every changeDocument and Hand Over
Runbooks, image conventions and secrets handling are written down and walked through with your team.
Team can maintain it
What Affects the Cost of Containerisation
Docker's core tooling is open source, though some Docker products carry licence terms to check for your organisation. These are the drivers that shape the scope.
Number of services
Each service needs its own image, configuration and tests.
Age of the application
Older software with hidden dependencies takes longer to package cleanly.
Pipeline integration
Fitting builds into an existing CI system varies with how it is set up.
Secrets and security scanning
Handling credentials and scanning images properly adds design and set-up.
Target hosting
Running on plain servers, a managed container service or Kubernetes changes the work.
Team training
Teaching your engineers to work with containers affects how much handover time is needed.
Why Build With Docker and NetOfficials
The working terms below are part of every engagement, not extras.
One Cross-Functional Team
Design, development, testing and DevOps run through a single team, so decisions stay connected.
Senior From Day One
The senior engineer who scopes your work stays involved while it is delivered.
You Own Everything
IP assignment is confirmed in the contract, and you receive the full source code and documentation at handover.
Mutual NDA
We sign a mutual NDA before you share the details of your project.
Your Working Hours
We agree a communication window that suits your time zone at the start.
Visible Progress
Work is tracked in Jira, with a demo and your feedback at the end of every sprint.
Tools Around Docker
We recommend technology for your project and your team's future, not for our convenience. Three questions guide every choice.
Will it handle your load?
We size the design for your expected users, data and growth, so it does not need rebuilding when the business grows.
Will it fit your systems?
We check how the stack connects with the tools, databases and partners you already rely on before we commit to it.
Can you support it later?
We favour well-supported technology with a wide talent pool, so your own team or any future partner can maintain it.

Docker and Containerisation FAQs
What does containerising an application mean?
It means packaging the application with its dependencies into an image that runs the same everywhere. You then start containers from that image instead of installing software by hand.
Do we need Kubernetes as well?
Not always. A few services can run well with Docker alone. Kubernetes helps when you need to run and manage many containers across servers.
Can you containerise a legacy application?
Often yes. We start by finding its dependencies and configuration, then decide what can be packaged as is and what needs changes first.
Are containers secure?
They can be, with small base images, non-root users, scanning and careful secrets handling. We agree the security steps in the scope.
Can Docker help new developers get started?
Yes. A Compose file can start the application and its database together, so a new engineer avoids a long manual set-up.
Who owns the Dockerfiles and pipeline code?
You do. The contract settles ownership before work starts, and the files and runbooks are handed to you with the finished set-up.
