  • The containers with an issue are on the worker node, same with a redis deployment. The Cri is crio, there must be something I missed during the install.
    Or maybe it's the pod Cidr, I've set 192.168/16 and it could be too big for Aws

  • In file /etc/kubernetes/manifests/kube-controller-manager.yaml, I tried to set the Cidr to 192.169.0/24, but the nodes remain in 192.168/16:

    1. $ kubectl get nodes -o jsonpath='{.items[*].spec.podCIDR}'
    2. 192.168.0.0/24 192.168.1.0/24
  • Something must have gone wrong during the install, it's working now
