Changes from Previous Release

This release introduces the following new feature:

• The Greenplum Operator manifest file supports a new attribute named hostBasedAuthentication under the masterAndStandby key. You can use this attribute to insert entries into the pg_hba.conf file that is generated for a new Greenplum cluster. For example, the following configuration enables the gpadmin and gpuser accounts to access the Greenplum cluster from any external client address:

  masterAndStandby:
    # TYPE   DATABASE       USER           CIDR-ADDRESS      METHOD
    hostBasedAuthentication: |
      host   all            gpadmin        0.0.0.0/0         trust
      host   all            gpuser         0.0.0.0/0         md5
  

  See Allowing Connections to Greenplum Database in the Greenplum Database documentation for more information about pg_hba.conf file entries.

Known Issues and Limitations

• Pivotal Greenplum for Kubernetes is an experimental product and is not intended for use in a production environment. Experimental features are subject to change without notice in future releases.
• The Greenplum Operator does not yet support changing attribute values of a deployed Greenplum cluster. In order to change attributes such as the number of segments in the cluster, the cluster name, or segment resource usage, you must delete the cluster and then redeploy using the changed values.
• In order to install Greenplum Database package (.gppkg) files, such as MADLib, with the gppkg utility, you must first install the alien utility onto Greenplum hosts (for example, sudo apt-get install alien).
• Certain Greenplum resources that are created during deployment are not yet labeled for convenient management with kubectl. This includes Greenplum secret objects, ConfigMap, Services.
