A Mirantis OpenStack for Kubernetes (MOSK) deployment profile is a thoroughly tested and officially supported reference architecture that is guaranteed to work at a specific scale and is tailored to the demands of a specific business case, such as generic IaaS cloud, Network Function Virtualisation infrastructure, Edge Computing, and others.
A deployment profile is defined as a combination of:
Services and features the cloud offers to its users.
Non-functional characteristics that users and operators should expect when running the profile on top of a reference hardware configuration. Including, but not limited to:
Performance characteristics, such as an average network throughput between VMs in the same virtual network.
Reliability characteristics, such as the cloud API error response rate when recovering a failed controller node.
Scalability characteristics, such as the total amount of virtual routers tenants can run simultaneously.
Hardware requirements - the specification of physical servers, and networking equipment required to run the profile in production.
Deployment parameters that an operator for the cloud can tweak within a certain range without being afraid of breaking the cloud or losing support.
In addition, the following items may be included in a definition:
Compliance-driven technical requirements, such as TLS encryption of all external API endpoints.
Foundation-level software components, such as Tungsten Fabric or Open vSwitch as a back end for the networking service.
Mirantis reserves the right to revise the technical implementation of any profile at will while preserving its definition - the functional and non-functional characteristics that operators and users are known to rely on.
MOSK supports a huge list of different deployment profiles to address a wide variety of business tasks. The table below includes the profiles for the most common use cases.
Some components of a MOSK cluster are mandatory and are being installed during the managed cluster deployment by MCC regardless of the deployment profile in use. StackLight is one of the cluster components that are enabled by default. See MCC Operations Guide for details.
OpenStackDeployment CR Preset
Cloud Provider Infrastructure (CPI)
Provides the core set of the services an IaaS vendor would need including some extra functionality. The profile is designed to support up 50-70 compute nodes and a reasonable number of storage nodes. 0
The core set of services provided by the profile includes:
CPI with Tungsten Fabric
A variation of the CPI profile 1 with Tugsten Fabric as a back end for networking.
The supported node count is approximate and may vary depending on the hardware, cloud configuration, and planned workload.
Ironic is an optional component for the CPI profile. See Bare metal OsDpl configuration for details.
Ironic is not supported for the CPI with Tungsten Fabric profile. See Tungsten Fabric known limitations for details.
Telemetry services are optional components and should be enabled together through the list of services to be deployed in the
OpenStackDeploymentCR as described in Deploy an OpenStack cluster.
