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
sysctl is set to a large number. Do this on any
worker node that may host any
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.
