1、Delete a module（Take so as an example）
    
    helm delete dev-so --purge

2、 If delete failed, you can manually delete pvc、pv、deployment、configmap、statefulset、job

3、Install a module
    
    cd oom/kubernests
    make so
    meke onap
    helm install local/so --namespace onap --name dev-so
    
     or(under the circumstance that use docker proxy repository)
     helm install local/so --namespace onap --name dev-so --set global.repository=172.30.1.66:10001
     
    Use a proxy repository when installing a module or define a mirror policy for a module
    helm install local/so --namespace onap --name dev-so --set global.repository=172.30.1.66:10001 --set so.pullPolicy=IfNotPresent
     
    
4、Clear /dockerdata-nfs/dev-so file( can mv to /bak directory)

1. Check the node where pod belongs to

       kubectl get pod -n onap -o wide|grep uui-server

 2、Check the type of pod controller (ReplicaSet corresponds to deployment, statefulset corresponds to statefulset)

        kubectl -n onap describe pod dev-uui-uui-server-67fc49b6d9-szr7t|grep Controlled

 3、Check the deployment corresponding to pod

        kubectl get svc -n onap |grep uui-server

4、 Access pod according to  floating ip where the pod is located and 30000+ port   

1、Check the corresponding service according to the exposed port(take 30399 port as an example)

       kubectl -n onap get svc |grep 30399

 2、Check the backend pod ip corresponding with this service

        kubectl get ep uui-server -n onap

 3、Check the corresponding pod and node through pod ip

      kubectl get pod -n onap -o wide|grep 10.42.67.201

 4、cat /etc/hosts |grep node4

HOMELES doesn't have a auto-deploy problem
manually deploy holmes

1) enter into dcae bootstrap's pod
>>kubectl exec -it -n onap dev-dcaegen2-dcae-bootstrap-776cf86d49-mxzq6 /bin/bash


2) Delete holmes components
>>cfy uninstall holmes_rules
>>cfy deployments delete -f holmes_rules
>>cfy blueprints delete holmes_rulescfy blueprints validate k8s-holmes-rules.yaml


>>cfy uninstall holmes_engine
>>cfy deployments delete -f holmes_engine
>>cfy blueprints delete holmes_engine


3) Restall holmes components



>>cfy blueprints upload -b holmes_rules /blueprints/k8s-holmes-rules.yaml
>>cfy deployments create -b holmes_rules -i /inputs/k8s-holmes_rules-inputs.yaml holmes_rules
>>cfy executions start -d holmes_rules install 



>>cfy blueprints upload -b holmes_engine /blueprints/k8s-holmes-engine.yaml
>>cfy deployments create -b holmes_engine -i /inputs/k8s-holmes_engine-inputs.yaml holmes_engine
>>cfy executions start -d holmes_engine install



If restalling holmes fail, following bugs will occur ：
[root@dev-dcaegen2-dcae-bootstrap-9b6b4fb77-fnsdk blueprints]# cfy deployments create -b holmes_rules -i /inputs/k8s-holmes_rules-inputs.yaml holmes_rules

Need to execute following steps first：

1） Delete holmes components as the step 2 above

2）Reset the Postgres instance
a. Uninstall the pg initialization blueprint
cfy uninstall pgaas_initdb
cfy deployments delete -f pgaas_initdb
cfy blueprints delete pgaas_initdb

b.  Reset the password of PG via psql
kubectl exec -it -n onap dev-dcaegen2-dcae-db-0 /bin/sh
bash-4.2$ psql
postgres=# ALTER ROLE "postgres" WITH PASSWORD 'onapdemodb';
ALTER ROLE
postgres-# \q

c. Deploy PG initialization blueprint
cfy blueprints upload -b pgaas_initdb /blueprints/k8s-pgaas-initdb.yaml
cfy deployments create -b pgaas_initdb -i /inputs/k8s-pgaas-initdb-inputs.yaml pgaas_initdb
cfy executions start -d pgaas_initdb install


3）Restall holmes as step 3 above

1、Check the update history of deployment
kubectl rollout history deployment nginx-deployment

2、Rollback to the last version

kubectl rollout undo deployment nginx-deployment

3、Rollback to the specified version
kubectl rollout undo deployment nginx-deployment --to-revision=2

#!/usr/bin/env bash

        cd $HOME
        git clone -b casablanca https://gerrit.onap.org/r/integration
        cp $HOME/integration/version-manifest/src/main/resources/docker-manifest.csv $HOME/oom/
        
        version_new="$HOME/oom/docker-manifest.csv"
        for line in $(tail -n +2 $version_new); do
                image=$(echo $line | cut -d , -f 1)
                tag=$(echo $line | cut -s -d , -f 2)
                perl -p -i -e "s|$image(:.*$\|$)|$image:$tag|g" $(find $HOME/oom/ -name values.yaml)
        done

1、Delete using helm

    helm delete $(helm list|tail -n +2|awk '{print $1}') --purge &
    
 2、 Delete the rest api objects in onap in k8s
  
     kubectl -n onap get deployments|tail -n +2 |awk '{print $1}'|xargs kubectl -n onap delete deployments
     kubectl -n onap get statefulset|tail -n +2 |awk '{print $1}'|xargs kubectl -n onap delete statefulset
     kubectl -n onap get jobs|tail -n +2 |awk '{print $1}'|xargs kubectl -n onap delete jobs
     kubectl -n onap get pvc|tail -n +2 |awk '{print $1}'|xargs kubectl -n onap delete pvc
     kubectl -n onap get secrets|tail -n +2 |awk '{print $1}'|xargs kubectl -n onap delete secrets
     kubectl -n onap get configmaps|tail -n +2 |awk '{print $1}'|xargs kubectl -n onap delete configmaps
     kubectl -n onap get svc|tail -n +2 |awk '{print $1}'|xargs kubectl -n onap delete svc
   
3、Delete data in nfs

1、Export from the current environment, take cm in multicloud as an example

    kubectl -n onap get cm dev-vfc-vfc-catalog-logging-configmap --export -o yaml >>dev-vfc-vfc-catalog-logging-configmap.yaml
    
2、kubectl -n onap applay -f dev-vfc-vfc-catalog-logging-configmap

3、Restart pod

The nodeport field specified in the service deployed by the helm is not exported. The reason is being checked.

 ports:
  - port: 9090
    protocol: TCP
    targetPort: 80
    nodePort: 32000


targetPort is the port where docker provides service

Port is the port that the service in the cluster providing access 

NodePort is to specify the exposed port through the nodePort mode. By default, it is randomly assigned. The port range is 30,000-32767
