Frankfurt Notes

In addition to the mechanisms from El Alto for deploy/undeply the standard helm commands also work. For example in the case to upgrade a specific component like AAI without having to do a helm delete/heml deploy you can use the following:

Example with aai charts

Precondition: 

helm deploy has previously been run with override files on the command line so that the .helm/plugins/deploy/cache has been populated

git clone aai to an aai_oom directory since it is a recursive submodule of oom and upgrade using these newly cloned charts

Helm command:

helm upgrade -i onap-aai  ./aai_oom --namespace onap --timeout 900 -f ${HOME}/.helm/plugins/deploy/cache/onap/global-overrides.yaml -f ${HOME}/.helm/plugins/deploy/cache/onap-subcharts/aai/subchart-overrides.yaml

El Alto Notes with new Deploy/Undeploy plugin from OOM Team

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

For slower cloud environment use this to use longer interval for readiness

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

Example per prodjest with SO:

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

If you are using the SNAPSHOT image override file:

helm deploy dev-sdnc local/onap -f /root/oom/kubernetes/onap/resources/environments/public-cloud.yaml -f /root/integration-override.yaml -f /root/integration/deployment/heat/onap-rke/staging-image-override.yaml --namespace onap --verbose

1. After editing a chart 
   1. cd /root/oom/kubernetes
   2. make project
      
      1. note that for cds/sdnc you need to do make cds; make sdnc
   3. make onap
2. helm del project --purge
   1. helm list -a to confirm its gone
   2. also check pvc's for applications like sdnc/appc and kubectl -n onap delete pvc any remaining ones
      1. kubectl -n onap get pv  | grep project
      2. kubectl -n onap get pvc | grep  project
      3. ...
      4. "delete /dockerdata-nfs/dev-project"
   3. Cleanup shared cassandra (aai, sdc) and shared maiadb (sdnc, so)
   4. /root/integration/deployment/heat/onap-rke/cleanup.sh  project(without dev-)
      1. example: ./cleanup.sh sdc
      2. this script cleans up the shared cassandra and mariadb as well as pvc, pv, jobs etc.
      3. if you get an error when doing aai or sdc check to make sure cassandra cleaned up correctly. We have known problem where the cluster does not let schema's to be replicated and you get a Timeout back to cleanup.sh
3. Rebuild helm charts as necessary
   1. cd /root/oom/kubernetes
   2. make project
   3. make onap
4. helm deploy dev local/onap -f /root/oom/kubernetes/onap/resources/environments/public-cloud.yaml -f /root/integration-override.yaml --namespace onap  --verbose
5. list pods and ports (with k8 host)
   1. kubectl -n onap get pods -o=wide 
   2. kubectl -n onap get services
6. Find out why pod is stuck in initializing or crash loopback
   1. kubectl -n onap describe pod dev-blah-blah-blah
   2. kubectl -n onap logs dev-blah-blah-blah
      
      

complete removal steps (same as Beijing) 

### Faster method to do a delete for reinstall

kubectl delete namespace onap

kubectl delete pods -n onap --all

kubectl delete secrets -n onap --all

kubectl delete persistentvolumes -n onap --all

kubectl -n onap delete clusterrolebindings --all

helm del --purge dev

helm list -a

helm del --purge dev-[project] ← use this if helm list -a shows lingering  releases in DELETED state

if you have pods stuck terminating for a long time

kubectl delete pod --grace-period=0 --force --namespace onap --all

CDS Specific Notes (Dublin) - In Dublin release, the CDS charts are added as a subchat in OOM. However, the deployment of CDS charts is achieved as part of the SDN-C deployment in Dublin release. Thus, if any changes required to be made in the CDS chart the following steps taking:  "make cds; make sdnc ; make onap"

SDNC Values.yaml chart in OOM

105 cds:
106   enabled: true

helm upgrade -i dev local/onap --namespace onap -f integration-override.yaml

# to upgrade robot

# a config upgrade should use the local/onap syntax to let K8 decide based on the parent chart (local/onap)

helm upgrade -i dev local/onap --namespace onap -f integration-override.yaml

# if docker container changes use the enable:false/true

helm upgrade -i dev local/onap --namespace onap -f integration-override.yaml --set robot.enabled=false

helm upgrade -i dev local/onap --namespace onap -f integration-override.yaml --set robot.enabled=true

# if  both the config and the docker container changes use the enable:false, do the make component, make onap  then enable:true

helm upgrade -i dev local/onap --namespace onap -f /root/integration-override.yaml --set robot.enabled=false

Confirm the assets are removed with get pods , get pv, get pvc, get secret, get configmap for those pieces you dont want to preserve

cd  /root/oom/kubernetes

make robot

make onap

helm upgrade -i dev local/onap --namespace onap -f /root/integration-override.yaml --set robot.enabled=true

kubectl get pods --all-namespaces -o=wide

# to check status of a pod like robots pod

kubectl -n onap describe pod dev-robot-5cfddf87fb-65zvv

### Faster method to do a delete for reinstall

kubectl delete namespace onap

kubectl delete pods -n onap --all

kubectl delete secrets -n onap --all

kubectl delete persistentvolumes -n onap --all

kubectl -n onap delete clusterrolebindings --all

helm del --purge dev

helm list -a

helm del --purge dev-[project] ← use this if helm list -a shows lingering  releases in DELETED state

if you have pods stuck terminating for a long time

kubectl delete pod --grace-period=0 --force --namespace onap --all

# of NAME=dev release

helm upgrade -i dev local/onap --namespace onap -f integration-override.yaml

To test with a smaller ConfigMap try to disable some things like:

helm upgrade -i dev local/onap --namespace onap -f /root/integration-override.yaml --set log.enabled=false --set clamp.enabled=false --set pomba.enabled=false --set vnfsdk.enabled=false

(aaf is needed by alot of modules in Casablanca  but this is a near equivalent)

helm upgrade  -i dev local/onap --namespace onap -f /root/integration-override.yaml --set log.enabled=false --set aaf.enabled=false --set pomba.enabled=false --set vnfsdk.enabled=false

Note: setting log.enabled=false means that you will need to hunt down /var/log/onap logs on each docker container - instead of using the kibana search on the ELK stack deployed to port 30253 that consolidates all onap logs

## Slower method to delete full deploy

helm del dev --purge 

kubectl get pods --all-namespaces -o=wide

# look for all Terminating to be gone and wait till they are

kubectl -n onap get pvc

# look for persistant volumes that have not been removed.

kubectl -n onap delete pvc  dev-sdnc-db-data-dev-sdnc-db-0

# dev-sdnc is the name from the left  of the get pvc command

# same for pv (persistant volumes)

kubectl -n onap get pv

kubectl -n onap delete  pv  pvc-c0180abd-4251-11e8-b07c-02ee3a27e357

#same for pv, pvc, secret, configmap, services

kubectl get pods --all-namespaces -o=wide 

kubectl delete  pod dev-sms-857f6dbd87-6lh9k -n onap (stuck terminating pod )

# full install

# of NAME=dev instane 

helm upgrade -i dev local/onap --namespace onap -f integration-override.yaml

# update vm_properties.py

# robot/resources/config/eteshare/vm_properties.py

# cd to oom/kuberneties

Remember: Do the enabled=false BEFORE doing the make onap so that the kubectl processing will use the old chart to delete the POD

#

# helm upgrade -i dev local/onap --namespace onap -f integration-override.yaml - this would just redeploy robot becuase its configMap only

Container debugging commands

kubectl -n onap logs pod/dev-sdnc-0 -c sdnc
