Using GlusterFS in Kubernetes ( https://www.gluster.org/ There are endpoint (external storage) and heketi (k8s built-in GlusterFS service).This article focuses on using endpoint to set up GlusterFS storage for use in JupyterHub for K8s.For simplicity, install using the default JupyterHub helm.According to the Quick Setup JupyterHub for K8s Afte ...

Usually, the default k8s scheduling method is used, but in some cases, we need to run the pod on the node with the characteristic label to run them all. At this time, the pod's scheduling policy can not use the default k8s scheduling policy. At this time, we need to specify the scheduling policy, telling k8s that we need to schedule the pod on ...
