- 50. Demo Gerrit on Kubernetes managed by Gardener
- 51. Next steps Storage • use Ceph / Rook to replace NFS Update chart to enable using master branch • get rid of database
- 52. Index Replace Lucene by ElasticSearch
- 53. Gerrit Operator based on operator framework to implement • Sharding • Multi-master • Auto-Scaling
- 54. Logging EFK-Stack • Elastic search => Indexing • Fluentbit => Log-collection • Kibana => Visualization
- 55. Monitoring Prometheus => data collection Grafana => visualization
