v1.5.0

Release date: 11 June 2021

Features:

• Introduce the pg_basebackup bootstrap method to create a new PostgreSQL cluster as a copy of an existing PostgreSQL instance of the same major version, even outside Kubernetes
• Add support for Kubernetes’ tolerations in the Affinity section of the Cluster resource, allowing users to distribute PostgreSQL instances on Kubernetes nodes with the required taint
• Enable specification of a digest to an image name, through the <image>:<tag>@sha256:<digestValue> format, for more deterministic and repeatable deployments

Security Enhancements:

• Customize TLS certificates to authenticate the PostgreSQL server by defining secrets for the server certificate and the related Certification Authority that signed it
• Raise the sslmode for the WAL receiver process of internal and automatically managed streaming replicas from require to verify-ca

Changes:

• Enhance the promote subcommand of the cnp plugin for kubectl to accept just the node number rather than the whole name of the pod
• Adopt DNS-1035 validation scheme for cluster names (from which service names are inherited)
• Enforce streaming replication connection when cloning a standby instance or when bootstrapping using the pg_basebackup method
• Integrate the Backup resource with beginWal, endWal, beginLSN, endLSN, startedAt and stoppedAt regarding the physical base backup
• Documentation improvements:
  • Provide a list of ports exposed by the operator and the operand container
  • Introduce the cnp-bench helm charts and guidelines for benchmarking the storage and PostgreSQL for database workloads
• E2E tests enhancements:
  • Test Kubernetes 1.21
  • Add test for High Availability of the operator
  • Add test for node draining
• Minor bug fixes, including:
  • Timeout to pg_ctl start during recovery operations too short
  • Operator not watching over direct events on PVCs
  • Fix handling of immediateCheckpoint and jobs parameter in barmanObjectStore backups
  • Empty logs when recovering from a backup
