      • getHeaderBufferBytes

        public Integer getHeaderBufferBytes()
        headerBufferBytes describes how much memory should be reserved (in bytes) for IngressController connection sessions. Note that this value must be at least 16384 if HTTP/2 is enabled for the IngressController (https://tools.ietf.org/html/rfc7540). If this field is empty, the IngressController will use a default value of 32768 bytes.


        Setting this field is generally not recommended as headerBufferBytes values that are too small may break the IngressController and headerBufferBytes values that are too large could cause the IngressController to use significantly more memory than necessary.

      • setHeaderBufferBytes

        public void setHeaderBufferBytes​(Integer headerBufferBytes)
        headerBufferBytes describes how much memory should be reserved (in bytes) for IngressController connection sessions. Note that this value must be at least 16384 if HTTP/2 is enabled for the IngressController (https://tools.ietf.org/html/rfc7540).

      • getHeaderBufferMaxRewriteBytes

        public Integer getHeaderBufferMaxRewriteBytes()
        headerBufferMaxRewriteBytes describes how much memory should be reserved (in bytes) from headerBufferBytes for HTTP header rewriting and appending for IngressController connection sessions. Note that incoming HTTP requests will be limited to (headerBufferBytes - headerBufferMaxRewriteBytes) bytes, meaning headerBufferBytes must be greater than headerBufferMaxRewriteBytes. If this field is empty, the IngressController will use a default value of 8192 bytes.


        Setting this field is generally not recommended as headerBufferMaxRewriteBytes values that are too small may break the IngressController and headerBufferMaxRewriteBytes values that are too large could cause the IngressController to use significantly more memory than necessary.

        public String getHealthCheckInterval()

      • getMaxConnections

        public Integer getMaxConnections()
        maxConnections defines the maximum number of simultaneous connections that can be established per HAProxy process. Increasing this value allows each ingress controller pod to handle more connections but at the cost of additional system resources being consumed.


        Permitted values are: empty, 0, -1, and the range 2000-2000000.


        If this field is empty or 0, the IngressController will use the default value of 50000, but the default is subject to change in future releases.


        If the value is -1 then HAProxy will dynamically compute a maximum value based on the available ulimits in the running container. Selecting -1 (i.e., auto) will result in a large value being computed (~520000 on OpenShift >=4.10 clusters) and therefore each HAProxy process will incur significant memory usage compared to the current default of 50000.


        Setting a value that is greater than the current operating system limit will prevent the HAProxy process from starting.


        If you choose a discrete value (e.g., 750000) and the router pod is migrated to a new node, there's no guarantee that that new node has identical ulimits configured. In such a scenario the pod would fail to start. If you have nodes with different ulimits configured (e.g., different tuned profiles) and you choose a discrete value then the guidance is to use -1 and let the value be computed dynamically at runtime.


        You can monitor memory usage for router containers with the following metric: 'container_memory_working_set_bytes{container="router",namespace="openshift-ingress"}'.


        You can monitor memory usage of individual HAProxy processes in router containers with the following metric: 'container_memory_working_set_bytes{container="router",namespace="openshift-ingress"}/container_processes{container="router",namespace="openshift-ingress"}'.

      • getThreadCount

        public Integer getThreadCount()
        threadCount defines the number of threads created per HAProxy process. Creating more threads allows each ingress controller pod to handle more connections, at the cost of more system resources being used. HAProxy currently supports up to 64 threads. If this field is empty, the IngressController will use the default value. The current default is 4 threads, but this may change in future releases.


        Setting this field is generally not recommended. Increasing the number of HAProxy threads allows ingress controller pods to utilize more CPU time under load, potentially starving other pods if set too high. Reducing the number of threads may cause the ingress controller to perform poorly.
