Inventory
Identify privileged or host-dependent features
Container migration guide
Move a Docker workload to Seemi Cloud without losing its operating model
Separate image, configuration, secrets, ports, health checks, domains, and persistent data so the workload can be recreated predictably on managed container infrastructure.

OUR DELIVERY APPROACH
A controlled migration, led by experienced engineers
We assess the source, prove the transfer path, coordinate cutover, and stay through stabilization.
Assess platform fit
Replace host-local assumptions
Prepare images
Use versioned tags or image digests
Move persistent data
Quiesce writes where consistency requires it
Build and test
Test restart and recreate behavior
Cut over
Confirm managed TLS is ready
RISK CONTROL
Important risks are identified before cutover
Files stored only in the container writable layer are lost when the container is replaced.
Docker socket, privileged mode, host networking, devices, and arbitrary host mounts are restricted.
Environment files, image layers, Compose files, or committed containers can expose credentials.
An image built only for a different CPU architecture cannot run on the target node.
VALIDATION
Prove the target is ready
- Image pulls successfully from the approved registry
- Container reaches healthy state and remains stable through restart
- Required ports and domains work through managed ingress or native TCP routes
- Persistent data survives recreate and node-level recovery testing
ROLLBACK
Keep a safe path back
- Keep the old workload and data intact during the fallback window
- Preserve previous DNS and application configuration
- Define which system is allowed to accept writes during cutover
- If target received writes, decide how to reconcile before rollback

COMMON QUESTIONS
What clients usually ask before migration
Can Seemi run any Docker image?
The image must run in a supported Linux container environment without prohibited privileged or host-level access. Registry access, architecture, ports, persistence, and runtime requirements must be compatible.
Does docker image save include volume data?
No. Docker documents that attached volume data is not included in an image archive and must be backed up and migrated separately.
Can we migrate a Docker Compose stack unchanged?
Compose is useful as an inventory, but each service, network path, dependency, persistent volume, secret, and route must be translated into Seemi platform resources.
How is HTTPS handled after migration?
Eligible web applications can use managed ingress and TLS. Native TCP services use their protocol-specific security rather than browser HTTP termination.
