What's Changed
- Now 'clickhouse-operator' user is restricted to an IP address of the pod where clickhouse-operator is running. It can not be used from anywhere else.
- In addition to hostRegexp, 'default' user is restricted to IP addresses of pods of the CHI. This fixes connectivity issues between shards in GKE.
- ClickHouse 'interserver_http_host' is set to the service name and matches 'remote_servers'. It can be changed to full names with 'replicasUseFQDN' setting if needed. This fixes connectivity issues between replicas in GKE.
- Changed the way schema is propagated to new shards. It is currently controlled by two cluster level settings:
schemaPolicy:
replica: None | All (default)
shard: None | All (default) | DistributedTablesOnly
Previously, when adding shards only distributed tables and dependent objects were created (DistributedTablesOnly).
- Added support for adding custom CA for operator connection to ClickHouse by @SuzyWangIBMer in #930
- Fixed support of '{uuid}' macro for Atomic databases. Closes #857
- Fixed a bug when replica sometimes was not removed from ZooKeeper when scaling down the cluster
- Set container-log on ubi instead of busybox by @SuzyWangIBMer in #940
- upgrade vertamedia-clickhouse-grafana to 2.5.0 in dashboard and grafana 7.5.16 by @Slach in #951
- Improve grafana dashboards by @Slach in #952
- Improve grafana-operator + prometheus-operator by @Slach in #953
