6. HL Deployment Process - Preparation

7. HL Deployment Process - Configuration
Deploy config pod to all nodes or to one node and share it via NFS.
The pod brings all configuration files, secrets, DBs etc.
It creates /dockerdata-nfs directory on each node. This location will later be mapped to containers that will run on this node.

8. HL Deployment Process - components
Deploy all components.
Components have each an own namespace.
In a namespace there may be multiple pods.
There is an order in which pods should start. This order is achieved by readiness container that runs before pod deployment and ensures that relevant dependencies (other pods) are met.

9. Deployment Process For each component (behind the scenes):
Creation of Namespace (onap-XYZ, e.g. onap-appc)
Creation of Services (mapping of internal to internal ports)
Creation of pods
init stage runs readiness which waits for other pods to start
Map Environment Variables
start containers (dockers)
map volumes (files / directories)

10. Next Steps
Configuration Management – build infrastructure to provide simple and efficient parameter values per deployment
Replacement of configuration pod with ConfigMaps and Secrets
Deployment of DCAE gen2
Images download pre-deployment in order to make first deployment faster
