Google Distributed Cloud node pools also supportContainer-Optimized OS. Container-Optimized OS on Google Distributed Cloud
supportskdumpfor
debugging kernel issues.
Google Distributed Cloud offers the following node image options per OS for your
cluster:

General Availability
Kubernetes version
New Google Distributed Cloud versions sometimes introduce a new Kubernetes version
for clusters. Version changes are announced inRelease notes. To learn which
Kubernetes version your cluster runs, seeVersions.
Preinstalled tools
Google Distributed Cloud's node OS has the following tools preinstalled:arpingcloud-utils,conntrack,logrotate,prips,systemd-container
Google Distributed Cloud's node OS has thedebug-toolboxcontainer image
preinstalled.debug-toolboxincludes several packages for debugging node
issues. You run an accompanying shell script,toolbox, to unpack and run thedebug-toolboxcontainer.Learn about thetoolboxscript.
Networking
As of Google Distributed Cloud version 1.1.0-gke.6, the node OS' default
networking configuration is disabled to support static IP allocation.
