Kubernetes-based platform for serverless workloads. Knative provides a set of middleware components that are essential to build modern, source-centric, and container-based applications that can run anywhere: on premises, in the cloud, or even in a third-party data center.

Strong points

weakness

Full serverless platform

No persistent queue

Uses istio

Istio required

No GUI

Few faas platform helpers

How to increase Pods limit per worker node in Kubernetes

Image
Kubelet is close to pod limit Issue: The Alert Manager reported that our Kubelets running on the production nodes were running too many pods, close to the default limit of 110. Solution: First We need to take a look at Grafana dashboard to see if the nodes are able to receive more pods in terms of infrastructure resources (CPU/RAM, ....), then calculate the average of this resource utilization in order to determine the new value of pods limit on each node.   We suppose that the chosen value for the pods limit on nodes is 200, you can change it following these steps :     1.    Connect: First connect to the node (the worker with the issue):                                                                    $ ssh -i /path/to/your/ssh-key/id_rsa node-user@node-hostname node-user@node-hostname:~$ sudo -i  root@node-hostname:~#     2.    Edit: 
 Change the value KUBELET_MAX_PODS in the file /etc/default/kubelet from 110 to 200 ( use your favorite file edito
