Summary

Operational convention for reproducible deployments on DCP-controlled infrastructure: Git, repo/deploy, Docker/Compose, /opt/dcp, persistence, and recovery.

Container First is the operational default for software DCP installs and operates on Linux infrastructure it directly controls. The goal is reproducible, versioned, reconstructable deployments—not a universal Docker topology.

Git defines; the host executes

When Docker/Compose applies, the reproducible definition lives under repo/deploy/. On DCP hosts, /opt/dcp separates apps, data, backups, shared services, scripts, and host metadata to reduce drift and dependence on individual memory.

Key points
  • repo/deploy/ stores the definition.
  • /opt/dcp/apps/<project>/<environment> organizes deployments.
  • Persistent state must survive recreation.
  • Orphan services are an anti-pattern.

Container First is not Kubernetes First

Architecture remains project-specific. SaaS, managed services, serverless, static hosting, and constrained shared hosting may follow other runtime profiles. The target is reproducibility and explicit ownership, not containerization by dogma.

Key points
  • Docker topology is project-specific.
  • Development and production require isolation.
  • Backup needs verifiable restore.
  • A same-VM copy is not enough for production recovery.

Container First

DCP operational default for reproducible and normally containerized deployments on directly controlled Linux infrastructure, unless a documented technical exception applies.

Runtime Profile

Reproducible profile of the runtime environment required by a solution.

Deployment

Technical act of placing a version into an environment.

Operational Handoff

Explicit transfer of a system from delivery into operations and support.
