以下詳細指南及說明性範例以英語提供。所有範例業務紀錄均為虛構。
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.
