 Installation
 ============
 
-This document describes local build and installation for development purpose.
+.. contents::
+   :depth: 3
+..
 
-Pre-requisites
---------------
+This document describes Modeling/etsicatalog installation by OOM.
 
-* Python3 & pip
-* MariaDB
-
-Build & Run
+OOM Charts
 -----------
 
-**Clone repository**:
+The Modeling/etsicatalog K8S charts are located in the OOM repository:
+https://gerrit.onap.org/r/admin/repos/oom
+
+For OOM deployment you can refer to the below links:
+
+* https://docs.onap.org/projects/onap-oom/en/latest/oom_user_guide.html#oom-user-guide
+
+* https://docs.onap.org/projects/onap-oom/en/latest/oom_quickstart_guide.html#oom-quickstart-guide
+
+Installing or Upgrading
+------------------------
+
+The assumption is you have cloned the charts from the OOM repository into a local directory.
+
+Step 1 Go into local copy of OOM charts
+
+From your local copy, edit the values.yaml file to make desired changes.
+
+Step 2 Build the chart
 ::
 
-    $ git clone https://gerrit.onap.org/r/modeling/etsicatalog
-    $ cd etsicatalog
+    $ cd oom/kubernetes
+    $ make modeling
+    $ helm search local|grep modeling
 
-**Create database**::
+Step 3 Un-install if installed before
+::
 
-  $ cd /resources/dbscripts/mysql
+    $ helm delete  dev-modeling --purge
+    $ kubectl -n onap get pod |grep modeling-mariadb
 
-Run modeling-etsicatalog-createdb.sql to create database.
+Step 4 Delete persistent volume claim and NFS persisted data for etsicatalog
+::
 
-Run commands followed to init database::
+    $ kubectl -n onap get pvc |grep dev-modeling|awk '{print $1}'|xargs kubectl -n onap delete pvc
+    $ rm -rf /dockerdata-nfs/dev-modeling/
 
-  $ python manage.py makemigrations
-  $ python manage.py makemigrations database
-  $ python manage.py migrate
-  $ python manage.py migrate database
+Step 5 Reinstall
+::
 
-Review and edit \catalog\pub\config\config.py
+    $ helm install local/modeling --namespace onap --name dev-modeling
+    $ kubectl -n onap get pod |grep modeling
 
-MySQL default configuration is as follows::
 
-    DB_IP = "127.0.0.1"
-    DB_PORT = 3306
-    DB_NAME = "etsicatalog"
-    DB_USER = "etsicatalog"
-    DB_PASSWD = "etsicatalog"
+Etsicatalog Pods
+-----------------
 
-**Start server**::
+To get the etsicatalog Pod, run the following command:
+::
+
+    $ kubectl -n onap get pods | grep modeling
+
+    dev-modeling-etsicatalog-754f4d6f94-lmjzz       2/2     Running                 2          92d
 
-  $ python manage.py runserver 8806
+To access the etsicatalog docker container, run the command:
+::
 
+    $ kubectl -n onap exec -it dev-modeling-etsicatalog-754f4d6f94-lmjzz -c modeling-etsicatalog -- /bin/bash
 
+To restart the pod, run the command:
+::
 
-Test
-----
+    $ kubectl delete pod dev-modeling-etsicatalog-754f4d6f94-lmjzz -n onap
 
-**Run Healthcheck**::
+From Guilin Release, etsicatalog uses the public database:
+::
+
+   $ kubectl -n onap get pods | grep mariadb-galera
+
+   dev-mariadb-galera-0                               2/2     Running            0          14d
+   dev-mariadb-galera-1                               2/2     Running            0          14d
+   dev-mariadb-galera-2                               2/2     Running            0          14d
+
+Exposing ports
+---------------
+
+For security reasons, the port for the etsicatalog container is configured as ClusterIP and thus not exposed. If you need the port in a development environment, then the following command will expose it.
+::
 
-    GET /api/catalog/v1/health_check
+    $ kubectl -n onap expose service modeling-etsicatalog --target-port=8806 --type=NodePort
 
-You should get::
 
-    {
-        "status": "active"
-    }
