# ONAP APPC
---
In order to deploy APPC, a Docker-ready machine needs to be available in order to deploy the APPC Docker Containers. The following will help explain the requirements in order to run Docker to deploy these containers.
### APPC Docker Containers
-ONAP APPC docker images are currently stored on the Rackspace Nexus Docker Registry (Maven Repository). The deployment code can be found in the Maven Project that builds and deploys the Docker Images to be deployed in the Nexus Repository (current approach is by using Jenkins). These Docker Images are composed of the APPC Artifacts (org.openecomp.appc.*) compiled and packaged in the "appc" git repository.

These Docker Images are composed of the APPC Artifacts (org.onap.appc.*) compiled and packaged in the "appc" git repository.
The following Docker images are the actual deployment images used for running APPC:
- **APPC Container**: This Docker container carries the APPC Core Framework (OpenDaylight, Karaf, OSGI Bundles, ODL Functions/APIs, and APPC specific features). This image is built on top of the SDN-C Docker Image, which contains core features (such as dblib as the Database Connector, SLI - the Service Logic Interpreter, and the Active & Available Inventory (A&AI) Listener). Some of these inherited SDN-C features/artifacts are necessary dependencies to build and compile APPC features/artifacts.
```bash
# Install Docker-Compose
apt-get install python-pip
-pip install docker-compose
+pip install --no-cache-dir docker-compose
# Login to Nexus Repo to pull Docker Images (this assumes that Nexus Certificate is already imported in the Host VM on /usr/local/share/ca-certificates/ path):
docker login <DOCKER_REGISTRY_REPO> # prompts for user credentials as a way to authenticate
# Validating APPC Installation
-First of all, APPC Features come in the form of Karaf Features (an ODL-OpenDaylight package) which can be composed of one or more OSGI bundles. These features get installed in the ODL framework in order to be used and installed in the APPC Docker Container (NOTE: SDN-C Core Features also get installed since APPC docker image uses the SDN-C Core docker image as a base image).

### Accessing docker containers
# APPC Configuration Model
-APPC Configuration model involves using "default.properties" files (which are usually located in each of the APPC Features - ../<APPC_FEATURE_BUNDLE>/src/<MAIN_OR_TEST>/resources/org/openecomp/appc/default.properties) for APPC Feature that have default (or null) property values inside the core APPC code. These default (or null) properties should be overwritten in the properties file called "appc.properties" located in the APPC Deployment code (../installation/src/main/appc-properties/appc.properties).

These default (or null) properties should be overwritten in the properties file called "appc.properties" located in the APPC Deployment code (../installation/src/main/appc-properties/appc.properties).
Each APPC component depends on the property values that are defined for them in order to function properly. For example, the APPC Feature "appc-rest-adapter" located in the APPC Core repo is used to listen to events that are being sent and received in the form of DMaaP Messages through a DMaaP Server Instance (which is usually defined as a RESTful API Layer over the Apache Kafka Framework). The properties for this feature need to be defined to point to the right DMaaP set of events to make sure that we are sending and receiving the proper messages on DMaaP.
Currently, there are two ways to change properties for APPC Features:
- Permanent Change: In appc.properties, change property values as needed and commit changes in your current git repo where your APPC Deployment code repo is at. Then, run your Jenkins job that deploys the APPC Docker Image (make sure the Jenkins Job configuration points to the branch where you just commited the properties change) to make sure that APPC Docker Image contains latest changes of appc.properties from the beginning (of course, the Host VM where the docker containers will be deployed at needs to update images with "docker-compose pull" to pick up the changes you just committed and compiled).
-- Temporary Change (for quick testing/debugging): In the APPC Docker Container, find the appc.properties file in /opt/o
penecomp/appc/properties/appc.properties and make changes as needed. Then, restart the APPC Docker Container by running "docker stop <APPC_DOCKER_CONTAINER>" then "docker start <APPC_DOCKER_CONTAINER>") (NOTE: This approach will lose all changes done in appc.properties if the docker container is destroyed instead of stopped).
