How to Configure streamingConnectionIdleTimeout: "672h" Without Dynamic Kubelet Config

Problem

The customisations configured via Dynamic Kubelet Config previously for streamingConnectionIdleTimeout: "672h" is no longer possible __to use since moving to K8s v1.22 cluster on containerd where Dynamic Kubelet Config is deprecated, the setting is not taken into account as compared to docker previously.

Environment

• Platform9 Managed Kubernetes - v5.6.8 and Higher

Solution

Set the value stream_idle_timeout = "1m"in /etc/containerd/config.toml file for containerd service on the master node, takes into effect when kubectl client version below v1.20:

xxxxxxxxxx

/etc/containerd# containerd config dump | grep idle

    stream_idle_timeout = "1m"
