  • Upgrade notes:
    • If you are running a version of the Kaleido Platform earlier than v24.2.4 and followed the non-advanced installation guide, you will be using an instance CR specification that does not include the podSecurityContext setting. This will prevent some services, including Besu node services, from starting once the upgrade has taken place. Before doing the upgrade, you must apply the new instance CR included in this version of the documentation (see Creating Platform Instances section of the documentation for more details), or manually add the podSecurityContext section with fsGroup: 1001 to your existing instance CR. This applies to all cloud service providers. Due to limitations with KinD clusters, the podSecurityContext section is not honored correctly for existing PVCs. For development environments using KinD you must create new Besu node services in your existing Besu network.
