Description

Limitations

CORS filter

With Airlock Microgateway 4.6, we introduce the K8s Gateway API-based CORS filter support.

Cross-origin resource sharing (CORS) has been implemented with K8s Gateway API 1.4.x-experimental. To use this feature, you must install the Gateway API experimental channel.

mTLS

With Airlock Microgateway 4.8, we introduce the K8s Gateway API-based mTLS for downstream and upstream connections.

mTLS has been implemented with K8s Gateway API 1.4.x-experimental. To use this feature, you must install the Gateway API experimental channel.

 
Notice

In environments such as OpenShift, where only the Gateway API standard channel can be used, this feature is exposed via GatewayParameters.spec.experimental in the CR GatewayParameters.

If mTLS settings are configured in the CR GatewayParametersand the K8s Gateway API CRDs, the settings in GatewayParameters take precedence.

Once mTLS becomes available in the standard channel, the experimental mTLS settings will be removed from the GatewayParameters.

Downstream HTTP/3

With Airlock Microgateway 4.8, we introduce the K8s Gateway API-based support for HTTP/3 Downstream connections.

QUIC connection migration is not supported yet.

Upstream HTTP/3 is currently not supported.
