What This Is
Docker infrastructure is the operational side of containerisation — not building containers (that is covered on our Docker development page), but running them in production. This means container hosting, registry management, orchestration, networking, persistent storage, logging, monitoring, and the operational practices that keep containerised applications running reliably. The gap between “it works in Docker on my laptop” and “it runs in Docker in production” is where this work lives.
Running containers in production introduces infrastructure concerns that do not exist in development. Containers need to restart automatically when they crash. Logs need to be collected from ephemeral containers that are destroyed and recreated during deployments. Persistent data (databases, uploaded files) needs to survive container restarts. Networking between containers needs to be secure and observable. Image updates need to deploy without downtime. Health checks need to verify that containers are not just running but actually serving traffic correctly.
We manage Docker infrastructure for applications where containerisation provides clear operational benefits — consistent deployments, service isolation, and environment reproducibility. Not every application needs to run in containers, but for applications with multiple services, complex dependencies, or deployment pipelines that benefit from immutable artifacts, Docker infrastructure is the production foundation.
When You Need This
Docker infrastructure is the right choice when you are running containerised applications in production and need the operational layer managed properly. Common scenarios:
- You have a containerised application that needs production hosting with proper monitoring, logging, and restart policies
- Multi-service applications need container networking, service discovery, and coordinated deployment
- Your deployment pipeline produces Docker images and you need a registry, deployment strategy, and rollback capability
- Zero-downtime deployments are required, and your current container deployment causes brief outages during image swaps
- You need persistent storage for containerised databases or file storage that survives container recreation
- Log aggregation from multiple containers needs to be centralised for debugging and audit purposes
- Your container hosting needs to scale — either horizontally (more containers) or vertically (larger containers) based on load
This is not needed if your application runs on traditional server hosting without containers. Docker infrastructure adds value only when the application is already containerised or when containerisation solves a specific deployment or isolation problem.
How We Work
Docker infrastructure uses Docker Compose for single-host deployments and orchestration platforms for multi-host environments. For most applications we manage, Docker Compose on a well-provisioned server handles the production workload effectively. The simplicity of Compose — a single YAML file describing all services — means deployments are understandable, debuggable, and maintainable without specialist knowledge.
Production Compose files differ from development configurations. Production files do not mount source code volumes (the code is baked into the image). Restart policies ensure containers recover from crashes automatically. Memory and CPU limits prevent a single container from consuming all server resources. Health checks verify that services are responding correctly, not just that the process is running. Environment variables are managed through .env files that are not committed to version control.
Container networking uses Docker’s bridge networks to isolate services. Database containers are not exposed to the host network — they are accessible only to application containers on the same Docker network. Web-facing containers expose only the ports they need. This network isolation is a security benefit: even if an attacker compromises one container, the attack surface for lateral movement is limited to what the Docker network exposes.
Image management follows a build-push-pull-deploy workflow. CI builds the image and pushes it to a private registry. The production server pulls the new image and recreates the container. The previous image is retained for rollback. Image tags use commit hashes or semantic versions rather than latest, so every deployment is traceable to a specific code state.
Logging uses Docker’s logging drivers to forward container stdout/stderr to the host’s syslog, a log file, or a centralised logging service. Container logs are transient by default — when a container is destroyed, its logs disappear unless they are forwarded elsewhere. Production configurations ensure logs are persisted and searchable.
