What our Docker consulting covers

Whether you need a single image slimmed down or a full container strategy built from scratch, our work falls into six core areas.

Docker image optimisation

We audit your Dockerfiles, remove unnecessary layers, apply multi-stage builds, and cut image sizes so builds are faster and attack surfaces are smaller.

CI/CD pipeline integration

We wire Docker into your existing pipelines — GitHub Actions, GitLab CI, Jenkins, or CircleCI — so every commit builds, tests, and pushes a verified image automatically.

Container security hardening

We scan images for known vulnerabilities, enforce least-privilege runtime policies, and configure secure private registries so your containers are production-safe.

Docker Compose to Kubernetes migration

We map your Compose services to Kubernetes manifests or Helm charts, handling networking, secrets, and persistent storage so the transition doesn't break what already works.

Local-to-production environment parity

We eliminate the 'works on my machine' problem by aligning your development, staging, and production container configurations so bugs surface before they reach users.

Private registry setup and governance

We configure and secure container registries — whether AWS ECR, Google Artifact Registry, or a self-hosted option — with access controls, image signing, and retention policies.

From Docker Compose to Kubernetes: what the path actually looks like

Docker Compose is the right tool for running multi-container applications on a single machine or in a small team. It is fast to write, easy to read, and sufficient for many early-stage products. The problems start when you need rolling deployments, automatic restarts, horizontal scaling, or fine-grained resource limits — none of which Compose was designed to handle.

Kubernetes solves those problems, but it introduces real complexity. The gap between a working Compose file and a production-ready Kubernetes cluster is wider than most teams expect. Our approach bridges that gap in stages rather than forcing a full rewrite.

We typically move teams through the following progression:

  • Audit and map: We review your existing Compose services, volumes, environment variables, and networking to understand what needs to translate and what needs to change.
  • Convert to Kubernetes manifests or Helm charts: Each service becomes a Deployment, StatefulSet, or Job. Secrets move into Kubernetes Secrets or an external vault. Persistent volumes are mapped to PersistentVolumeClaims.
  • Introduce a managed cluster: For most teams, a managed service such as EKS, GKE, or AKS removes the overhead of maintaining the control plane and lets engineers focus on workloads rather than infrastructure.
  • Validate parity: We run both environments in parallel during transition, comparing behaviour under load before decommissioning the Compose setup.
  • Hand over with documentation: Your team receives runbooks, architecture diagrams, and a clear operational guide so the knowledge stays with you after the engagement ends.

The result is a container platform your team can operate confidently, with the headroom to scale without rebuilding the foundation.

Helping My Dobot turn a fintech concept into a market-ready product

My Dobot is a fintech start-up building an intelligent finance adviser bot that connects directly to users' bank accounts. The challenge was twofold: crafting a genuinely useful, trustworthy advisory experience whilst engineering a data-intensive application capable of handling sensitive financial data at bank-level security standards — all from an early proof-of-concept stage.

Netguru delivered end-to-end Ruby on Rails consulting, embedding development, project management, and QA expertise into every stage of the product's evolution. By implementing a scalable architecture underpinned by rigorous security practices, the team helped My Dobot move beyond proof-of-concept, earn a warm reception from early adopters, and establish the technical foundations needed to roll out new features quickly — backed by a high-quality, scalable development team.

We are working with front-end and mobile developers, but my resource from Netguru is one of the best developers I've ever worked with.

How an engagement with Netguru works, step by step

We keep the process straightforward so you spend time on your infrastructure, not on paperwork.

  1. Discovery call

    We spend 45–60 minutes understanding your current container setup, the problems you are trying to solve, and the constraints your team is working within.
  2. Technical scoping

    Our engineers review your existing Dockerfiles, CI configuration, and deployment setup to produce a clear picture of what needs to change and in what order.
  3. Proposal and team match

    We present a scoped proposal with timelines, deliverables, and the specific engineers we recommend for your engagement — no generic resource pools.
  4. Delivery in focused sprints

    Work is structured in short, reviewable sprints so you see progress weekly and can redirect priorities as your understanding of the problem deepens.
  5. Handover and knowledge transfer

    We close every engagement with documentation, a walkthrough session with your team, and a defined support window so nothing is left unexplained.

Common questions about Docker consulting with Netguru

How long does a Docker consulting engagement typically take?

Scope drives duration. A focused image optimisation and CI/CD integration project often completes in two to four weeks. A full migration from Docker Compose to a managed Kubernetes cluster, including security hardening and documentation, typically runs six to twelve weeks depending on the complexity of your services and the state of your existing infrastructure.

Can Netguru work with legacy applications that were not built for containers?

Yes. Many of the applications we containerise were originally deployed directly to virtual machines or bare-metal servers. We assess the application's dependencies, runtime requirements, and configuration patterns before recommending a containerisation approach. Some legacy apps need minor refactoring to run cleanly in a container; we flag those cases during scoping so there are no surprises.

How does container security hardening work in practice?

We work through several layers. First, we scan your base images and installed packages for known vulnerabilities using automated tooling and recommend updates or alternative base images where risks are material. Second, we review runtime configuration — dropping unnecessary Linux capabilities, running containers as non-root users, and setting read-only filesystems where the application allows it. Third, we audit registry access controls and image signing to ensure only verified images reach production. You receive a written summary of findings and the changes made, so your security team has a clear audit trail.

What does Docker consulting from Netguru cost?

Pricing depends on the scope, duration, and seniority of engineers involved. We work on a time-and-materials basis for most engagements, with a fixed-scope option available for clearly defined projects such as a Dockerfile audit or a CI/CD integration. The discovery call and technical scoping phase give both sides a clear picture of effort before any commitment is made.

Do you work with teams that already use Docker but want to improve their setup?

That is the most common starting point. Most teams we work with already have Docker running in some form — the problem is build times that have grown too long, images that are larger than they need to be, environments that drift between local and production, or CI pipelines that break unpredictably. We audit what you have, identify the highest-impact changes, and implement them alongside your team.

Will our team be able to maintain the infrastructure after the engagement ends?

That is a condition of how we work, not an optional extra. Every engagement closes with documentation written for the people who will operate the system day-to-day, a live walkthrough session, and a support window during which your team can ask questions as they take over. We measure success by whether your engineers feel confident running the infrastructure without us.

Ready to fix your container setup? Start with a scoping call.
