Hubble 25.4.2 Release Notes
Hubble version 25.4.2 is a maintenance release that addresses critical deployment issues affecting Red Hat Enterprise Linux (RHEL) 8 and 9 environments, focusing on Docker and docker-compose compatibility with modern infrastructure. The following table captures the resolved issues included in this release.
Resolved Issues
| Jira Reference | Title | Description |
|---|---|---|
Docker API Version Compatibility Error |
This release fixes a critical error where the message "client version 1.24 is too old. Minimum supported API version is 1.44" prevented Hubble containers from starting or stopping after upgrading to Docker Engine v29.x. The docker-compose component has been updated to support modern Docker versions that require API version 1.44 or higher. |
|
RHEL Version Support and Documentation |
This release resolves installation failures on RHEL 8.0 through 9.6 that were caused by an outdated docker-compose version (v1.23.2 from 2018). The update addresses Cyber Essentials compliance requirements and corrects documentation regarding Docker and Podman support on RHEL 8 and later versions. |
|
RHEL Deployment Failures |
This release fixes installation failures on RHEL 9.6 that were caused by an incompatible docker-compose version and Vault container startup issues. The fix eliminates the need for custom wrapper scripts during deployment. |
|
Release Consolidation Task |
This task consolidated and verified all maintenance release changes to ensure proper integration and testing of RHEL deployment fixes. |
