      # O-RAN-SC Hello World Xapp in Python
      This repository contains open-source code for a prototype python xAPP for near real-time
      RAN Intelligent Controller which makes use of python Xapp Framework.
      This xAPP aims to provide basic implementation of :
      1. A1 interfaces interactions
      2. Read-write operations into a persistent storage.
      3. xAPP Configuration management
      4. RMR Health Check
      5. xAPP SDL Check
      6. Raising alarms
      7. Generating metrics (TBD)
      8. E2 Interface intereactions (TBD)
      Introduction
      ------------
      This document provides guidelines on how to install and configure the HW Python xAPP in various environments/operating modes.
      The audience of this document is assumed to have good knowledge in RIC Platform.
      Preface
      -------
      This xAPP can be run directly as a Linux binary, as a docker image, or in a pod in a Kubernetes environment. The first
      two can be used for dev testing. The last option is how an xAPP is deployed in the RAN Intelligent Controller environment.
      This covers all three methods.
      1. Docker
      2. Linux Binary
      3. Kubernetes
      ##Build Process
      The HW xAPP can be either tested as a Linux binary or as a docker image.
      1. **Linux binary**: The HW xAPP may be compiled and invoked directly.
      Pre-requisite software packages that must be installed prior to
      compiling are documented in the Dockerfile in the repository.
      2. **Docker Image**:For building docker images, the Docker environment
      must be present in the system.
      Change to the root of the repository

      Software Installation and Deployment
      ------------------------------------
      ### Onboarding of hw-python using dms_cli tool
      `dms_cli` offers rich set of command line utility to onboard `hw-python` xapp
      to `chartmuseme`.
      First checkout the [hw-python](https://gerrit.o-ran-sc.org/r/ric-app/hw-python) repository from gerrit.
      ```
      git clone "https://gerrit.o-ran-sc.org/r/ric-app/hw-python"
      ```
      `hw-python` has following folder structure
      ```
      +---docs
      |
      +---hw_python.egg-info
      |
      +---init
      | config-file.json # descriptor for xapp deployment.
      | init_script.py
      | test_route.rt
      | schema.json #schema for validating the config-file.json
      |
      +---releases
      |
      +---resources
      |
      +---src
      ```
      For onboarding `hw-python` make sure that `dms_cli` and helm3 is installed. One can follow [documentation](https://docs.o-ran-sc.org/projects/o-ran-sc-it-dep/en/latest/installation-guides.html#ric-applications) to
      configure `dms_cli`.
      Once `dms_cli` is availabe we can proceed to onboarding proceure.
      configure the `export CHART_REPO_URL` to point `chartmuseme`.
      ```
      $export CHART_REPO_URL=http://<service-ricplt-xapp-onboarder-http.ricplt>:8080
      ```
      check if `dms_cli` working fine.
      ```
      $ dms_cli health
      True
      ```
      Now move to `init` folder to initiate onboarding.
      ```
      $ cd init
      $ dms_cli onboard --config_file_path=config-file.json --shcema_file_path=schema.json
      httpGet:
      path: '{{ index .Values "readinessProbe" "httpGet" "path" | toJson }}'
      port: '{{ index .Values "readinessProbe" "httpGet" "port" | toJson }}'
      initialDelaySeconds: '{{ index .Values "readinessProbe" "initialDelaySeconds" | toJson }}'
      periodSeconds: '{{ index .Values "readinessProbe" "periodSeconds" | toJson }}'
      httpGet:
      path: '{{ index .Values "livenessProbe" "httpGet" "path" | toJson }}'
      port: '{{ index .Values "livenessProbe" "httpGet" "port" | toJson }}'
      initialDelaySeconds: '{{ index .Values "livenessProbe" "initialDelaySeconds" | toJson }}'
      periodSeconds: '{{ index .Values "livenessProbe" "periodSeconds" | toJson }}'
      {
      "status": "Created"
      }
      ```
      Check if `hw-python` is onborded
      ```
      $ curl --location --request GET "http://<appmgr>:32080/onboard/api/v1/charts" --header 'Content-Type: application/json'
      {
      "hw-python": [
      {
      "name": "hw-python",
      "version": "1.0.0",
      "description": "Standard xApp Helm Chart",
      "apiVersion": "v1",
      "appVersion": "1.0",
      "urls": [
      "charts/hw-python-1.0.0.tgz"
      ],
      "created": "2021-07-05T15:07:34.518377486Z",
      "digest": "e9db874d35154643a2c6f26dd52929c9dcf143f165683c03d07518bb0c2d768d"
      }
      ],
      "hw-python": [
      {
      "name": "hw-python",
      "version": "1.0.0",
      "description": "Standard xApp Helm Chart",
      "apiVersion": "v1",
      "appVersion": "1.0",
      "urls": [
      "charts/hw-python-1.0.0.tgz"
      ],
      "created": "2021-07-05T15:20:13.965653743Z",
      "digest": "975b1da1f8669e8ed1b1e5be809e7cf4841ef33abcb88207bc3a735e9b543a9a"
      }
      ]
      }
      ```
      If we would wish to download the charts then we can perform following curl operation :
      ```
      curl --location --request GET "http://<appmgr>:32080/onboard/api/v1/charts/xapp/hw-python/ver/1.0.0" --header 'Content-Type: application/json' --output hw-python.tgz
      ```
      The downloaded folder has the deployment files for hw-python
      ```
      tar -xvzf hw-python.tgz
      hw-python/Chart.yaml
      hw-python/values.yaml
      hw-python/templates/_helpers.tpl
      hw-python/templates/appconfig.yaml
      hw-python/templates/appenv.yaml
      hw-python/templates/deployment.yaml
      hw-python/templates/service-http.yaml
      hw-python/templates/service-rmr.yaml
      hw-python/config/config-file.json
      hw-python/descriptors/schema.json
      ```
      Now the onboarding is done.
      ### Deployment of hw-python
      Once charts are available we can deploy the the `hw-python` using following curl command :
      ```
      $ curl --location --request POST "http://<appmgr>:32080/appmgr/ric/v1/xapps" --header 'Content-Type: application/json' --data-raw '{"xappName": "hw-python", "helmVersion": "1.0.0"}'
      {"instances":null,"name":"hw-python","status":"deployed","version":"1.0"}
      ```
      Deployment will be done in `ricxapp` ns :
      ```
      # kubectl get pods -n ricxapp
      NAME READY STATUS RESTARTS AGE
      ricxapp-hw-python-64b5447dcc-mbt5w 1/1 Running 0 5m45s
      CLUSTER-IP EXTERNAL-IP PORT(S) AGE
      aux-entry ClusterIP 10.111.35.76 <none> 80/TCP,443/TCP 9d
      service-ricxapp-hw-python-http ClusterIP 10.104.223.245 <none> 8080/TCP 6m23s
      service-ricxapp-hw-python-rmr ClusterIP 10.103.243.21 <none> 4560/TCP,4561/TCP 6m23s
      ```
      Now we can query to appmgr to get list of all the deployed xapps :
      ```
      # curl http://service-ricplt-appmgr-http.ricplt:8080/ric/v1/xapps | jq .
      % Total % Received % Xferd Average Speed Time Time Time Current
      Dload Upload Total Spent Left Speed

      "name": "hw-python-55ff7549df-kpj6k",
      "policies": [

      ],
      "port": 4560,
      "rxMessages": [

      ]
      }
      ],
      "name": "hw-python",
      "status": "deployed",
      "version": "1.0"
      }
      ]
      ```
      Logs from `hw-python` :
      ```

      Introduction
      ------------
      This document provides guidelines on how to install and configure the HW Python xAPP in various environments/operating modes.
      The audience of this document is assumed to have good knowledge in RIC Platform.
      Preface
      -------
      This xAPP can be run directly as a Linux binary, as a docker image, or in a pod in a Kubernetes environment. The first
      two can be used for dev testing. The last option is how an xAPP is deployed in the RAN Intelligent Controller environment.
      This document covers all three methods.
      Software Installation and Deployment
      ------------------------------------
      The build process assumes a Linux environment with python >= 3.8 and has been tested on Ubuntu. For building docker images,
      the Docker environment must be present in the system.
      Build Process
      ~~~~~~~~~~~~~
      The HW xAPP can be either tested as a Linux binary or as a docker image.
      1. **Linux binary**:
      TBD
      2. **Docker Image**: From the root of the repository, run *docker --no-cache build -t <image-name> ./* .
      Deployment
      ~~~~~~~~~~
      End to end deployment of `hw-python` can be referred at :
      :ref: `Deployment Guide`.

      ### Onboarding of hw-python using dms_cli tool
      `dms_cli` offers rich set of command line utility to onboard `hw-python` xapp
      to `chartmuseme`.
      First checkout the [hw-python](https://gerrit.o-ran-sc.org/r/ric-app/hw-python) repository from gerrit.
      .. code-block:: bash
      git clone "https://gerrit.o-ran-sc.org/r/ric-app/hw-python"
      `hw-python` has following folder structure
      .. code-block:: bash
      +---docs
      |
      +---hw_python.egg-info
      |
      +---init
      | config-file.json # descriptor for xapp deployment.
      | init_script.py
      | test_route.rt
      | schema.json #schema for validating the config-file.json
      |
      +---releases
      |
      +---resources
      |
      +---src
      For onboarding `hw-python` make sure that `dms_cli` and helm3 is installed. One can follow [documentation](https://docs.o-ran-sc.org/projects/o-ran-sc-it-dep/en/latest/installation-guides.html#ric-applications) to
      configure `dms_cli`.
      Once `dms_cli` is availabe we can proceed to onboarding proceure.
      configure the `export CHART_REPO_URL` to point `chartmuseme`.
      .. code-block:: bash
      $export CHART_REPO_URL=http://<service-ricplt-xapp-onboarder-http.ricplt>:8080
      check if `dms_cli` working fine.
      .. code-block:: bash
      $ dms_cli health
      True
      Now move to `init` folder to initiate onboarding.
      .. code-block:: bash
      $ cd init
      $ dms_cli onboard --config_file_path=config-file.json --shcema_file_path=schema.json
      httpGet:
      path: '{{ index .Values "readinessProbe" "httpGet" "path" | toJson }}'
      port: '{{ index .Values "readinessProbe" "httpGet" "port" | toJson }}'
      initialDelaySeconds: '{{ index .Values "readinessProbe" "initialDelaySeconds" | toJson }}'
      periodSeconds: '{{ index .Values "readinessProbe" "periodSeconds" | toJson }}'
      httpGet:
      path: '{{ index .Values "livenessProbe" "httpGet" "path" | toJson }}'
      port: '{{ index .Values "livenessProbe" "httpGet" "port" | toJson }}'
      initialDelaySeconds: '{{ index .Values "livenessProbe" "initialDelaySeconds" | toJson }}'
      periodSeconds: '{{ index .Values "livenessProbe" "periodSeconds" | toJson }}'
      {
      "status": "Created"
      }
      Check if `hw-python` is onborded
      .. code-block:: bash
      $ curl --location --request GET "http://<appmgr>:32080/onboard/api/v1/charts" --header 'Content-Type: application/json'
      {
      "hw-python": [
      {
      "name": "hw-python",
      "version": "1.0.0",
      "description": "Standard xApp Helm Chart",
      "apiVersion": "v1",
      "appVersion": "1.0",
      "urls": [
      "charts/hw-python-1.0.0.tgz"
      ],
      "created": "2021-07-05T15:07:34.518377486Z",
      "digest": "e9db874d35154643a2c6f26dd52929c9dcf143f165683c03d07518bb0c2d768d"
      }
      ],
      "hw-python": [
      {
      "name": "hw-python",
      "version": "1.0.0",
      "description": "Standard xApp Helm Chart",
      "apiVersion": "v1",
      "appVersion": "1.0",
      "urls": [
      "charts/hw-python-1.0.0.tgz"
      ],
      "created": "2021-07-05T15:20:13.965653743Z",
      "digest": "975b1da1f8669e8ed1b1e5be809e7cf4841ef33abcb88207bc3a735e9b543a9a"
      }
      ]
      }
      If we would wish to download the charts then we can perform following curl operation :
      .. code-block:: bash
      curl --location --request GET "http://<appmgr>:32080/onboard/api/v1/charts/xapp/hw-python/ver/1.0.0" --header 'Content-Type: application/json' --output hw-python.tgz
      The downloaded folder has the deployment files for hw-python
      .. code-block:: bash
      tar -xvzf hw-python.tgz
      hw-python/Chart.yaml
      hw-python/values.yaml
      hw-python/templates/_helpers.tpl
      hw-python/templates/appconfig.yaml
      hw-python/templates/appenv.yaml
      hw-python/templates/deployment.yaml
      hw-python/templates/service-http.yaml
      hw-python/templates/service-rmr.yaml
      hw-python/config/config-file.json
      hw-python/descriptors/schema.json
      ```
      Now the onboarding is done.
      ### Deployment of hw-python
      Once charts are available we can deploy the the `hw-python` using following curl command :
      .. code-block:: bash
      $ curl --location --request POST "http://<appmgr>:32080/appmgr/ric/v1/xapps" --header 'Content-Type: application/json' --data-raw '{"xappName": "hw-python", "helmVersion": "1.0.0"}'
      {"instances":null,"name":"hw-python","status":"deployed","version":"1.0"}
      Deployment will be done in `ricxapp` ns :
      ```
      # kubectl get pods -n ricxapp
      NAME READY STATUS RESTARTS AGE
      ricxapp-hw-python-64b5447dcc-mbt5w 1/1 Running 0 5m45s
      CLUSTER-IP EXTERNAL-IP PORT(S) AGE
      aux-entry ClusterIP 10.111.35.76 <none> 80/TCP,443/TCP 9d
      service-ricxapp-hw-python-http ClusterIP 10.104.223.245 <none> 8080/TCP 6m23s
      service-ricxapp-hw-python-rmr ClusterIP 10.103.243.21 <none> 4560/TCP,4561/TCP 6m23s
      ```
      Now we can query to appmgr to get list of all the deployed xapps :
      ```
      # curl http://service-ricplt-appmgr-http.ricplt:8080/ric/v1/xapps | jq .
      % Total % Received % Xferd Average Speed Time Time Time Current

      "name": "hw-python-55ff7549df-kpj6k",
      "policies": [

      ],
      "port": 4560,
      "rxMessages": [

      "RIC_HEALTH_CHECK_REQ"
      ],
      "status": "running",
      "txMessages": [
      "RIC_SUB_REQ",
      "A1_POLICY_RESP",
      "A1_POLICY_QUERY",

      ]
      }
      ],
      "name": "hw-python",
      "status": "deployed",
      "version": "1.0"
      }
      ]
      ```
      Logs from `hw-python` :
      ```

      HelloWorld xAPP (Python)
      ============================================================================================
      --------------------------------------------------------------------------------------------
      User's Guide
      --------------------------------------------------------------------------------------------
      Introduction
      ============================================================================================
      The RIC platform provides set of functions as part of xAPP Python Framework that the xAPPs can use to accomplish their tasks.
      This xAPP is envisioned to provide python xAPP developers, examples of implementing these sets of functions.
      Note, HW xAPP does not address/implement any RIC Usecases.
      HelloWorld xAPP Features
      ============================================================================================
      RIC Platform provides many Frameworks, APIs and libraries to aid the development of xAPPs. All xAPPs will have some custom
      processing functional logic core to the xApp and some additional non-functional platform related processing using
      these APIs and libraries. This xAPP attempts to show the usage of such additional platform processing using xapp RIC framework APIs and libraries.
      The Hello World xApp demonstrates how a python based xApp uses the A1, and E2 interfaces and persistent database read-write operations.
