- joshribakoff 8y agoKubernetes also has auto scale.
- dharmab 8y agoYou can use one of the two container autoscalers to handle the scaling automatically based on any metric(s) you like, and the cluster autoscaler will scale the ASG as needed :) This is useful for workloads that need to scale on some metric other than CPU/MEM, e.g. request rate, worker queue length...
- merb 8y agosadly it's not cheap to built aws on bare metal.
- geggam 8y agoAnd you think k8s is simple to run on bare metal ? To care and maintain ? Do you understand the kernel tuning and routing Google does to avoid the NAT hell you are going to run into when you manage k8s on your own ?
- merb 8y agoI actually run 3 small bare metal clusters in production. Maintain is basically just a `kubeadm upgrade` on all nodes + reboot (easily scriptable), after some updates get announced. OS Upgrades are done through container-linux-update-operator. NAT is not a problem if you are below or equal to 50 nodes. Not sure if you run into problems if there are more nodes, thought. Also BGP+metallb is quite good. (P.S.: openstack uses NAT heavily as well. and IPVS for k8s should fix most problems if you are running into problems)
