以下の詳しいガイドと説明用の事例は英語です。例に含まれる業務データは架空のものです。

Where Docker fits

A documented, repeatable deployment environment.

When to choose another approach

An image is not a backup, security audit or staffed operations service.

Worked example and evidence

Fictional stock app: build a versioned image, inject secrets separately, release through staging and restore the previous image if release checks fail.

What you need to supply

Build access, dependencies, persistent data locations, secrets inventory and host.

What acceptance should demonstrate

A second maintainer deploys from instructions and demonstrates rollback plus a separate data restore.

Running costs and responsibilities

Assign image updates, registry/host charges, patching, backups, secrets and response.

Technical scope to confirm

Distinguish replaceable application containers from persistent business data.

A proposal should identify the systems and data, direction of sync, access feasibility, failure handling, named owners and included deliverables. Listing this technology does not imply a prebuilt connector, vendor partnership or included feature.

Does containerizing my app require microservices?

No. A single application can be containerized. Split services only for a clear delivery or operating need.
