OOM Quick Start Guide

Once a kubernetes environment is available (follow the instructions in
:ref:`cloud-setup-guide-label` if you don't have a cloud environment
available), follow the following instructions to deploy ONAP.

**Step 1.** Clone the OOM repository from ONAP gerrit::

  > git clone -b 4.0.0-ONAP http://gerrit.onap.org/r/oom --recurse-submodules
  > cd oom/kubernetes

**Step 2.** Install Helm Plugins required to deploy ONAP::

  > sudo cp -R ~/oom/kubernetes/helm/plugins/ ~/.helm


**Step 3.** Customize the helm charts like oom/kubernetes/onap/values.yaml or an override
file like onap-all.yaml, onap-vfw.yaml or openstack.yaml file to suit your deployment with items like the
OpenStack tenant information.

.. note::
  Standard and example override files (e.g. onap-all.yaml, openstack.yaml) can be found in 
  the oom/kubernetes/onap/resources/overrides/ directory.


 a. You may want to selectively enable or disable ONAP components by changing
    the `enabled: true/false` flags.


 b. Encyrpt the OpenStack password using the shell tool for robot and put it in
    the robot helm charts or robot section of openstack.yaml


 c. Encrypt the OpenStack password using the java based script for SO helm charts
    or SO section of openstack.yaml.


 d. Update the OpenStack parameters that will be used by robot, SO and APPC helm
    charts or use an override file to replace them.


a. Enabling/Disabling Components:
Here is an example of the nominal entries that need to be provided.
We have different values file available for different contexts.

.. literalinclude:: onap-values.yaml
   :language: yaml


b. Generating ROBOT Encrypted Password:
The ROBOT encrypted Password uses the same encryption.key as SO but an
openssl algorithm that works with the python based Robot Framework.

.. note::
  To generate ROBOT openStackEncryptedPasswordHere :

  ``cd so/resources/config/mso/``

  ``/oom/kubernetes/so/resources/config/mso# echo -n "<openstack tenant password>" | openssl aes-128-ecb -e -K `cat encryption.key` -nosalt | xxd -c 256 -p``

c. Generating SO Encrypted Password:
The SO Encrypted Password uses a java based encryption utility since the
Java encryption library is not easy to integrate with openssl/python that
ROBOT uses in Dublin.

.. note::
  To generate SO openStackEncryptedPasswordHere :

  SO_ENCRYPTION_KEY=`cat ~/oom/kubenertes/so/resources/config/mso/encrypt.key`
  OS_PASSWORD=XXXX_OS_CLEARTESTPASSWORD_XXXX

  git clone http://gerrit.onap.org/r/integration
  cd integration/deployment/heat/onap-oom/scripts
  javac Crypto.java
  java Crypto "$OS_PASSWORD" "$SO_ENCRYPTION_KEY"


d. Update the OpenStack parameters:

.. literalinclude:: example-integration-override.yaml
   :language: yaml

**Step 4.** To setup a local Helm server to server up the ONAP charts::

  > helm serve &

Note the port number that is listed and use it in the Helm repo add as
follows::

  > helm repo add local http://127.0.0.1:8879

**Step 5.** Verify your Helm repository setup with::

  > helm repo list
  NAME   URL
  local  http://127.0.0.1:8879

**Step 6.** Build a local Helm repository (from the kubernetes directory)::

  > make all; make onap

**Step 7.** Display the onap charts that available to be deployed::

  > helm search onap -l

.. literalinclude:: helm-search.txt

.. note::
  The setup of the Helm repository is a one time activity. If you make changes to your deployment charts or values be sure to use `make` to update your local Helm repository.

**Step 8.** Once the repo is setup, installation of ONAP can be done with a
single command

.. note::
  The --timeout 900 is currently required in Dublin to address long running initialization tasks
  for DMaaP and SO. Without this timeout value both applications may fail to deploy.

 a. To deploy all ONAP applications use this command::

    > cd oom/kubernetes
    > helm deploy dev local/onap --namespace onap -f onap/resources/overrides/onap-all.yaml -f onap/resources/overrides/openstack.yaml --timeout 900

 b. If you are using a custom override (e.g. integration-override.yaml) use this command::

    > helm deploy dev local/onap -f /root/integration-override.yaml --namespace onap --timeout 900


 c. If you have a slower cloud environment you may want to use the public-cloud.yaml
    which has longer delay intervals on database updates.::

    > helm deploy dev local/onap -f /root/oom/kubernetes/onap/resources/environments/public-cloud.yaml -f /root/integration-override.yaml --namespace onap --timeout 900


**Step 9.** Commands to interact with the OOM installation

Use the following to monitor your deployment and determine when ONAP is
ready for use::

  > kubectl get pods -n onap -o=wide

Undeploying onap can be done using the following command::

  > helm undeploy dev --purge


More examples of using the deploy and undeploy plugins can be found here: https://wiki.onap.org/display/DW/OOM+Helm+%28un%29Deploy+plugins
