Deploy KubeCF

Few heads up while deploying KubeCF

Deploying on RHEL / CentOS 7 -based Kubernetes

If you are deploying with diego (that is, Eirini is not enabled) on top of a RHEL / CentOS 7 based cluster, please make sure that the user.max_user_namespaces sysctl is set to a large number. Do this on any worker node that may host any diego-cell workloads:

sudo sh -c 'sysctl -w user.max_user_namespaces=15076 | tee -a /etc/sysctl.conf'

This is not necessary on RHEL / CentOS 8 based systems.
