From Dublin AAI would use the common instance of Cassandra cluster. The common Cassandra cluster is a new sub component of ONAP and can be installed by setting cassandra.enabled=true in the overrides or command line.
1. Fresh Dublin:
helm deploy demo local/onap --version=4.0.0 --namespace onap --set global.pullPolicy=IfNotPresent --set aai.enabled=true --set cassandra.enabled=true --set aaf.enabled=true --verbose --timeout 1200 root@new-k8s-1:~/Mahendra/OOM_Dublin# kubectl get pod -n onap

Note: aai-spike is in INIT as no dmaap (lack of resources).
2. Upgrade Casablanca to Dublin (In-place upgrade):
To allow in-place upgrade, Cassandra upgrade strategy should be RollingUpdate in the Casablanca.
2.1 Install Casablanca:
helm deploy demo local/onap --version=3.0.0 --namespace onap -f onap/resources/environments/disable-allcharts.yaml --set aai.enabled=true --set aai.global.aafEnabled=false --set global.pullPolicy=IfNotPresent --timeout 1200 --verbose root@new-k8s-1:~/Mahendra/OOM_Dublin/AAI_ROLLING_UP_MERGED/oom/kubernetes# kubectl get pod -n onap|grep -v aaf

2.2 Upgrade to Dublin:

3. Install Dublin as a parallel site to Casablanca (The Cassandra cluster of AAI from Casablanca site should be exposed to outside world):
| helm deploy demo local/onap --version=4.0.0 --namespace onap --set aai.enabled=true --set global.pullPolicy=IfNotPresent --verbose --timeout 1200 --set aai.global.jobs.migration.enabled=true --set aai.global.jobs.migration.remoteCassandra.enabled=true --set aai.global.jobs.migration.remoteCassandra.storage.hostname=10.53.234.224 --set cassandra.enabled=true --set aaf.enabled=true --set robot.enabled=true |
|---|
4. Subsequent upgrades from Dublin onward:
a. With Migration:
| helm deploy demo local/onap --version=4.0.0 --namespace onap --set global.pullPolicy=IfNotPresent --set aai.enabled=true --set aai.global.jobs.migration.enabled=true --set cassandra.enabled=true --set aaf.enabled=true --set robot.enabled=true --verbose --timeout 1200 |
|---|
b. Without Migration:
| helm deploy demo local/onap --version=4.0.0 --namespace onap --set global.pullPolicy=IfNotPresent --set aai.enabled=true --set cassandra.enabled=true --set aaf.enabled=true --set robot.enabled=true --verbose --timeout 1200 |
|---|
5. Running AAI with its own cluster:
AAI will create its own cassandra cluster for its specific use instead of connecting to the common Cassandra cluster, Below command will instantiate the aai cassandra instances:
| helm deploy demo local/onap --version=4.0.0 --namespace onap --set aai.enabled=true --set aai.global.cassandra.localCluster=true --set aai.global.cassandra.serviceName=aai-cassandra |
|---|
Note:The AAI specific cluster will be using the common Cassandra charts to instantiate the nodes of the cluster.
