SO How to over OOM

This is an initial draft and up for comments before uploading to the readthedocs.

gerrit

Pulling code :

Following are the repository which are required to be pulled

gerrit

# Repository which contains source code for SO
git clone ssh://<LFID>@gerrit.onap.org:29418/so && scp -p -P 29418 <LFID>@gerrit.onap.org:hooks/commit-msg so/.git/hooks/

# This repository is libraries for openstack services
git clone ssh://<LFID>@gerrit.onap.org:29418/so/libs && scp -p -P 29418 <LFID>@gerrit.onap.org:hooks/commit-msg libs/.git/hooks/

# This repository contains required docker configs for various dockers
git clone ssh://<LFID>@gerrit.onap.org:29418/so/docker-config && scp -p -P 29418 <LFID>@gerrit.onap.org:hooks/commit-msg docker-config/.git/hooks/

After cloning repository one can use mvm to build code.

$ mvn clean install

If you want to switch branch to any any specific tag, release :

git checkout <branch-name> # current active branches master, casablanca etc...

SO docker images and docker build

Following are the list of dockers required for SO deployment

$ docker ps

Below are the responsibilities of each module

docker-config_mariadb_1 # responsible for handling the DB store (mariadb).
docker-config_api-handler-infra_1 # responsible for handling the DB store (mariadb).
docker-config_sdc-controller_1 # responsible for handling CSAR distribution and parsing.
docker-config_bpmn-infra_1 # responsible for executing BMPN worklows.
docker-config_vfc-adapter_1 is # responsible for communicating with VFC.
docker-config_sdnc-adapter_1 # responsible for communicating with SDNC.
docker-config_openstack-adapter_1 # responsible for comomunicating with openstack.
docker-config_catalog-db-adapter_1 # responsible for API to communicate with DB.
docker-config_request-db-adapter_1 # responsible for API to track requests details.
docker-config_so-monitoring_1 # responsible for Monitoring.

One can create docker image locally from code using following command from /so/packages/docker:

$ mvn clean install -U -DskipTests=true -Dmaven.test.skip=true -Dmaven.javadoc.skip=true -Dadditionalparam=-Xdoclint:none -P docker

For creating docker image you need to run the above command from /so/package/docker

To run the docker images go to /docker-config folder which was cloned from the above command and run the command

$ docker-compose up -d

SO docker deployment

For initialization of docker there are 2 deployment options currently adpoted in ONAP:
- using heat template
- using OOM

OOM based deployment

- for installing and configuring SO using OOM deployment one can refer to the below links:

https://onap.readthedocs.io/en/latest/submodules/oom.git/docs/oom_setup_kubernetes_rancher.html
https://onap.readthedocs.io/en/latest/submodules/oom.git/docs/oom_quickstart_guide.html#quick-start-label

- Ensure SO is marked true against field enabled in the oom/oom_setup_kubernetes\onap\values.yaml for successful deployment.

===== values.yaml =====
so:
enabled: true

replicaCount: 1

liveness:
# necessary to disable liveness probe when setting breakpoints
# in debugger so K8s doesn't restart unresponsive container
enabled: true

# so server configuration
config:
# message router configuration
dmaapTopic: "AUTO"
# openstack configuration
openStackUserName: "vnf_user"
openStackRegion: "RegionOne"
openStackKeyStoneUrl: "http://1.2.3.4:5000"
openStackServiceTenantName: "service"
openStackEncryptedPasswordHere: "c124921a3a0efbe579782cde8227681e"

# configure embedded mariadb
mariadb:
config:
mariadbRootPassword: password

Upgrade Images in OOM deployment

To Upgrade SO image one has to modify the the image for the respective component in SO charts by modifying values.yaml

e.g.

====== oom/kubernetes/so/charts/so-bpmn-infra/values.yaml =====
...
repository: nexus3.onap.org:10001
image: onap/so/bpmn-infra:1.3.3
pullPolicy: Always
...

Now build the charts after modifying image version following the below sequence of commands:

step1: Build all repos again

$ make all # from path oom/kubernetes

step2: Delete the existing pods already deployed

$ helm del dev-so --purge # delete previous existing deployment

step3: Deploy the new pods.

$ helm deploy dev local/onap --namespace onap

Now SO will be upgraded with new image version.

Pull Daily Images in OOM deployment

To pull the daily image one can go to https://nexus3.onap.org/#browse/browse:docker.snapshot and pull the appropriate image tag by following previous steps.

Testing your patch

- To test patch developer has to replace corresponding `jar` files in pod to path `/app` in corresponding pod. This can be done using :

$ kubectl cp mso-infrastructure-bpmn-1.3.0-SNAPSHOT.jar onap/dev-so-so-bpmn-infra-54db5cd955-h7f5s:/app/mso-infrastructure-bpmn-1.3.0-SNAPSHOT.jar

- Modify your \app\start-appp.sh to specify name of your jar as follows :

===== start-app.sh =====
java ${jvmargs} -jar mso-infrastructure-bpmn-1.3.0-SNAPSHOT.jar

- Now, restart docker instance from corresponding node.

$ docker restart <docker-name>

SO debug logging

To see the various logs on can go to /app/log folder inside corresponding pod e.g. /app/logs/bpmn for bpmn related logs.
