Server load Balancer (SLB) Ingresses will be phased out on February 28, 2023. ACK Serverless no longer provides technical support for SLB Ingresses after they are phased out. After SLB Ingresses are phased out, you cannot install or manage the SLB Ingress controller in an ACK Serverless cluster. To avoid service interruptions, we recommend that you migrate from SLB Ingresses to ALB Ingresses at the earliest opportunity. For more information, see Migrate from SLB Ingresses to ALB Ingresses.
