Docker

Containerization of services with lean images and repeatable local-to-prod parity.

Docker and container baseline work for applications that need portable, repeatable runtime packaging. We produce sensible Dockerfiles, compose setups for local development, and image build practices that keep layers lean and secrets out of the image.

Who it’s for

  • Teams moving from host-installed runtimes to containers
  • Engineering orgs standardizing local developer environments
  • Groups preparing workloads for Kubernetes or container hosts

Problems we address

  • “Works on my machine” gaps between developers and servers
  • Bloated images with unclear build provenance
  • Secrets and config accidentally baked into images

Expected outcomes

  • Multi-stage Dockerfiles tuned to your runtime
  • Compose-based local stacks for dependent services
  • Build arguments and runtime config separated cleanly

  5. 05

    Deployment

    Controlled release to staging and production with rollback paths.

  6. 06

    Handover

    Runbooks, access notes, and operator/admin walkthrough.

FAQ

No. Many teams run containers on a single host, ECS/Fargate, or similar without Kubernetes. We recommend orchestration only when the operational need is real.

Often yes, with constraints. Some legacy systems need staged extraction or sidecar patterns rather than a perfect first-pass image.
