+## Deploying the Helm Chart

+
+````bash
+POSTGRES_HOST=postgres-postgresql
+MASTER_KEY=my_artifactory_master_key
+JOIN_KEY=my_artifactory_join_key
+helm upgrade --install openshift-xray . \
+               --set xray.database.url=postgres://$POSTGRES_HOST:5432/xraydb?sslmode=disable \
+               --set xray.database.user=artifactory \
