Introduction
The ONAP Operations Manager (OOM) is responsible for life-cycle management of the ONAP platform itself; components such as MSO, SDNC, etc. It is not responsible for the management of services, VNFs or infrastructure instantiated by ONAP or used by ONAP to host such services or VNFs. OOM uses the open-source Kubernetes container management system as a means to manage the Docker containers that compose ONAP where the containers are hosted either directly on bare-metal servers or on VMs hosted by a 3rd party management system. OOM ensures that ONAP is easily deployable and maintainable throughout its life cycle while using hardware resources efficiently.
In summary OOM provides the following capabilities:
- Deployment - with built-in component dependency management (including multiple clusters, federated deployments across sites, and anti-affinity rules)
- Configuration - unified configuration across all ONAP components
- Monitoring - real-time health monitoring feeding to a Consul UI and Kubernets
- Heal- failed ONAP containers are recreated automatically
- Clustering and Scaling - cluster ONAP services to enable seamless scaling
- Upgrade - change-out containers or configuration with little or no service impact
- Deletion - cleanup individual containers or entire deployments
OOM supports a wide variety of cloud infrastructures to suit your individual requirements.

Quick Start Guide
Once a kubernetes environment is available (check out ONAP on Kubernetes if you're getting started) and the deployment artifacts have been customized for your location, ONAP is ready to be installed.
The first step is to setup the /oom/kubernetes/config/onap-parameters.yaml file with key-value pairs specific to your OpenStack environment. There is a sample that may help you out or even be usable directly if you don't intend to actually use OpenStack resources.
In-order to be able to support multiple ONAP instances within a single kubernetes environment a configuration set is required. The createConfig.sh script is used to do this.
> ./createConfig.sh -n onapTrial
The bash script createAll.bash is used to create an ONAP deployment with kubernetes. It has two primary functions:
- Creating the namespaces used to encapsulate the ONAP components, and
- Creating the services, pods and containers within each of these namespaces that provide the core functionality of ONAP.
> ./createAll.bash -n onapTrial
Namespaces provide isolation between ONAP components as ONAP release 1.0 contains duplicate application (e.g. mariadb) and port usage. As such createAll.bash requires the user to enter a namespace prefix string that can be used to separate multiple deployments of onap. The result will be set of 10 namespaces (e.g. onapTrial-sdc, onapTrial-aai, onapTrial-mso, onapTrial-message-router, onapTrial-robot, onapTrial-vid, onapTrial-sdnc, onapTrial-portal, onapTrial-policy, onapTrial-appc) being created within the kubernetes environment. A prerequisite pod config-init (pod-config-init.yaml) may need editing to match your environment and deployment into the default namespace before running createAll.bash.

OOM Architecture and Technical Details
OOM uses the Kubernetes container management system to orchestrate the life cycle of the ONAP infrastructure components. If you'd like to learn more about how this works or develop the deployment specifications for a project not already managed by OOM look here: OOM User Guide.
OOM Configuration Management
OOM provides capabilities to manage the configuration parameters of an ONAP deployment. For more information refer to OOM Configuration Management.
OOM Production-Grade Deployments
ONAP can be deployed as a carrier grade application as described in OOM for Production-Grade Deployments.
