Installation Guide#
Mirantis Secure Registry (MSR) supports two installation scenarios designed to meet most customer needs:
- High availability installation
- Single host installation using Docker
- Single host installation using Helm
The following comparison highlights key differences to help you choose the most appropriate option for your environment.
| Installation Scenario | Detail |
|---|---|
| High Availability | Deployment of MSR in a high availability configuration on Kubernetes using Helm charts. Benefits - Provides the highest resiliency and uptime. - Leverages Kubernetes orchestration with three or more nodes running in an active-active configuration. - Includes guidance for installing PostgreSQL and Redis in a high availability configuration. Use case Production environments of medium to large enterprises, where uptime is critical. |
| Single host using Docker Compose | High availability is not supported. Thus, if the MSR instance becomes unavailable, there is no orchestrator to provide redundancy. Benefits - Does not require Kubernetes or Helm/OCI Charts. Use case Non-production environments, or smaller enterprises or office sites. Also suitable for non-Kubernetes environments. |
| Single host using Helm | Deployment of MSR on a single-node Kubernetes cluster using Helm charts. High availability is not supported. Thus, if the MSR instance becomes unavailable, there is no orchestrator to provide redundancy. Benefits - Allows use of Kubernetes and Helm tooling even in small or non-production environments. - Provides a deployment experience consistent with larger Kubernetes-based installations. Use case Non-production environments, proofs of concept, development scenarios, or small sites that want to use Kubernetes tooling but do not require high availability. |
Some organizations may have unique infrastructure requirements or prefer
custom deployment strategies that extend beyond the scope outlined here.
While Mirantis supports a wide range of use cases, official support is limited
to the configurations described above.
