Release Notes
=============

Version: 3.0.0
--------------

:Release Date: 2018-11-16

**New Features**

DCAE R3 improves upon previous release with the following new features:

- All DCAE R3 components are delivered as Docker container images.  The list of components is as follows. 
    - Platform components
        - Cloudify Manager
        - Bootstrap container
        - Configuration Binding Service
        - Deployment Handler
        - Policy Handler
        - Service Change Handler
        - Inventory API
    - Service components
        - VES Collector
        - SNMP Collector
        - Threshold Crossing Analytics
        - Holmes Rule Management *
        - Holmes Engine Management *
    - Additional resources that DCAE utilizes:
        - Postgres Database
        - Redis Cluster Database
        - Consul Cluster

    Notes:
        \*  These components are delivered by the Holmes project and used as a DCAE analytics component in R3.

- DCAE R3 supports both OpenStack Heat Orchestration Template based deployment and OOM (Kubernetes) based deployment. 

    - Under Heat based deployment all DCAE component containers are deployed onto a single Docker host VM that is launched from an OpenStack Heat Orchestration Template as part of "stack creation".
    - Under OOM (Kubernetes) deployment all DCAE component containers are deployed as Kubernetes Pods/Deployments/Services into Kubernetes cluster.

- DCAE R3 includes a new Cloudify Manager plugin (k8splugin) that is capable of expanding a Blueprint node specification written for Docker container to a full Kubernetes specification, with additional enhancements such as replica scaling, sidecar for logging to ONAP ELK stack, registering services to MSB, etc. 

- All DCAE components are designed to support platform maturity requirements.

**Bug Fixes**

**Known Issues**

- DCAE utilizes Cloudify Manager as its declarative model based resource deployment engine.  Cloudify Manager is an open source upstream technology provided by Cloudify Inc. as a Docker image.  DCAE R2 does not provide additional enhancements towards Cloudify Manager's platform maturity.

**Security Notes**

DCAE code has been formally scanned during build time using NexusIQ and all Critical vulnerabilities have been addressed, items that remain open have been assessed for risk and determined to be false positive. The DCAE open Critical security vulnerabilities and their risk assessment have been documented as part of the `project <https://wiki.onap.org/pages/viewpage.action?pageId=28377647>`_.

Version: 1.0.0
--------------

:Release Date: 2017-11-16


**New Features**

DCAE is the data collection and analytics sub-system of ONAP.  Under ONAP Release 1 the DCAE
sub-system includes both platform components and DCAE service components.  Collectively the ONAP R1
DCAE components support the data collection and analytics functions for the R1 use cases, i.e. vFW,
vDNS, vCPU, and vVoLTE.

Specifically, DCAE R1 includes the following components:

- Core platform
    - Cloudify manager
    - Consul cluster
- Extended platform
    - Platform component docker host
    - Service component docker host
    - CDAP cluster
    - PostgreSQL database (*)
- Platform docker container components
    - Configuration binding service
    - Deployment handler
    - Service change handler
    - Inventory
    - Policy handler
    - CDAP broker
- Service components                            
    - Docker container components
        - VNF Event Streaming (VES) collector
        - Holmes (engine and rule management) **
    - CDAP analytics component
        - Threshold Crossing Analytics (TCA)

(*) Note: This component is delivered under the CCSDK project, deployed by DCAE under a single 
VM configuration as a shared PostgreSQL database for the R1 demos.  (CCSDK PostgreSQL supports 
other deployment configurations not used in the R1 demos.)
(**) Note: This component is delivered under the Holmes project and used as a DCAE analytics component 
in R1.

Source codes of DCAE are released under the following repositories on gerrit.onap.org:

- dcaegen2
- dcaegen2/analytics
- dcaegen2/analytics/tca
- dcaegen2/collectors
- dcaegen2/collectors/snmptrap
- dcaegen2/collectors/ves
- dcaegen2/deployments

- dcaegen2/platform/inventory-api
- dcaegen2/platform/plugins
- dcaegen2/platform/policy-handler
- dcaegen2/platform/servicechange-handler
- dcaegen2/utils


**Bug Fixes**

This is the initial release.


**Known Issues**

- Need to test/integrate into an OpenStack environment other than Intel/Windriver Pod25.
- Need to provide a dev configuration DCAE.


**Security Issues**

- The DCAE Bootstrap container needs to have a secret key for accessing VMs that it launches.  This key is currently passed in as a Heat template parameter.  Tracked by JIRA `DCAEGEN2-178 <https://jira.onap.org/browse/DCAEGEN2-178>`_.>`_.
- The RESTful API calls are generally not secure.  That is, they are either over http, or https without certificate verification.  Once there is an ONAP wide solution for handling certificates, DCAE will switch to https.


**Upgrade Notes**

This is the initial release.


**Deprecation Notes**

There is a GEN1 DCAE sub-system implementation existing in the pre-R1 ONAP Gerrit system.  The GEN1
DCAE is deprecated by the R1 release.  The DCAE included in ONAP R1 is also known as DCAE GEN2.  The
following Gerrit repos are voided and already locked as read-only.
