Restarting a container is not a recovery plan
Containers can be recreated from images, but orders, uploads and databases usually live in persistent storage. Updating an image without understanding migrations can make a simple rollback unsafe. We review the application and its data together. This service focuses on Docker and Compose workloads; large orchestration platforms and custom application development require a separate assessment.
Protect container configuration and persistent data
Images can be replaced while business data requires its own protection. Map Compose configuration, image references, ports, networks, secrets and volumes before a deployment change. A running process is not proof of application readiness.
- Identify image, configuration and data owners.
- Review ports, privileges and secrets.
- Plan the version change and data recovery point.
- Verify application function and persistence.
Images, volumes and application readiness
Provide a deployment description with secrets removed. Separate image updates from data migrations in the handover. Volumes retain data outside the lifecycle of a container, but that persistence is not a backup. Agree how each volume is copied and restored, and test persistence during the authorized deployment change.
| Object | Check | Limit |
|---|---|---|
| Image | Known version and source | Rollback may not reverse schema changes |
| Volume | Backup and restore method | Container recreation is not backup |
| Readiness | Application transaction succeeds | Process state alone is insufficient |
Example: recreate a container without losing its data
Before recreating a database container, locate its persistent data and confirm a recovery method. Avoid destructive prune operations as a diagnostic shortcut. This is an illustrative scenario, not a customer case or a promised result.
