charts/gateway 3.0.2

[Gazza7205]

Description of the change To reduce reliance on requiring a custom/derived gateway image for custom and modular assertions, scripts and restman bundles a bootstrap script has been introduced. The script works with the /opt/docker/custom folder.

The best way to populate this folder is with an initContainer where files can be copied directly across or dynamically loaded from an external source.

• InitContainer Examples - this repository also contains examples for custom health checks and configuration files.

The following configuration options have been added

• Custom Health Checks
• Custom Configuration Files
• Topology Spread Constraints
• Tolerations
• Pod Security Context
• Container Security Context
• Http headers can also now be added to the liveness and readiness probes
• Ingress and HPA API Version validation has been updated to check for available APIs vs. KubeVersion
• SubCharts now show image repository and tags

Benefits

• Additional features available for configuration
