Enterprise Platform 0.9.0 Release Notes

August 27th, 2025

Breaking changes

  • Four subcharts in the enterprise-platform chart were Bitnami charts: postgresql, minio, kafka, and clickhouse. The images used by these charts will no longer be maintained by Bitnami, as of 2025-08-28. These subcharts are mostly useful for proof of concepts. Often, you will want to use your own postgres / S3 / kafka / clickhouse infrastructure instead.

Migration Strategy

To address the Bitnami image deprecation, we've created custom Helm charts for these accessory services:

  • Custom charts created for PostgreSQL, Kafka, and ClickHouse to have full control over configuration and avoid external dependencies
  • Replaced MinIO chart with the official MinIO chart from https://charts.min.io/
  • All services now use official Docker images from their respective projects

Migration from Bitnami Charts

To address the Bitnami deprecation, the following changes have been made:

  1. PostgreSQL: Custom chart created (replacing bitnami/postgresql)

    • Uses official PostgreSQL Docker image (postgres:17)
    • Simplified configuration with direct environment variables
    • Maintains compatibility with existing service names and connection strings
    • Supports Helm hooks for proper deployment ordering

  2. Kafka: Custom chart created (replacing bitnami/kafka)

    • Uses official Apache Kafka Docker image (apache/kafka:3.9.0)
    • Configured for KRaft mode (no Zookeeper dependency)
    • Single-node configuration for simplicity
    • Automatic node ID assignment based on pod hostname

  3. ClickHouse: Custom chart created (replacing bitnami/clickhouse)

    • Uses official ClickHouse Docker image (clickhouse/clickhouse-server:24.11)
    • Configuration via environment variables to avoid read-only filesystem issues
    • Simplified user and database setup
    • Service naming remains compatible ({{ release }}-clickhouse)

  4. MinIO: Migrated from bitnami/minio to the official MinIO chart from https://charts.min.io/ (v5.4.0)

    • Configuration changes:
      • auth.rootUser → rootUser
      • auth.rootPassword → rootPassword
      • Service configuration structure has changed

Required Configuration Updates

Users upgrading from v0.8.x will need to update their values files:

  • PostgreSQL values remain largely compatible, but hook annotations can now be configured
  • Kafka configuration simplified to essential settings (replicas, storage, resources)
  • ClickHouse configuration simplified to auth settings (username, password, database)
  • MinIO configuration must be updated to match the new chart structure
  • The duplicate replicated-supportbundle secret template has been removed from the main chart
