Docker Disaster Recovery Checklist

20 March 2026 · 8 min read

Container infrastructure requires a deliberate backup and recovery strategy. This checklist covers the essentials for disaster recovery in Docker environments.

Container Image Pinning

Never rely on latest tags in production. Pin your images to specific digest hashes:

version: '3.8'
services:
  app:
    image: myapp@sha256:abcd1234...

Store the mapping of semver to digest in your deployment manifest.

Volume Backup Strategy

For stateful services, implement regular snapshots:

• Database volumes: daily snapshots with retention policy
• Config volumes: version-controlled, backed up via Git
• User data: incremental backups to S3-compatible storage

Recovery Runbook

Document your recovery path:

1. Identify the failure scope (single container vs. entire host)
2. Restore images from private registry
3. Mount backup volumes
4. Verify application health before switching traffic
5. Post-incident review and manifest updates

Testing Recovery

Schedule quarterly recovery drills. Automated testing catches configuration drift early.
