Fermilab has made the strategic decision to deploy OKD, the open source version of Red Hat OpenShift, for Kubernetes container management. We will discuss our experience so far with OKD and describe some of the challenges we faced deploying a variety of applications.
Exploring how the kubelet, with Calico as the CNI plugin,
depends on the performance of the Kubernetes API server
to be able to start pods quickly.
At the moment, Kubernetes only supports horizontal pod autoscaling based on predefined pod metrics (CPU and memory usage). Therefore, in order to achieve an actually green elastic cloud model (optimizing resource usage) a key point is to integrate this tool with autoscaling solutions based on custom metrics, and this requires the usage of third-party elements.
In this work we show the...
The PanDA team has evaluated the possibility of native Kubernetes job submission in order to process ATLAS workloads and offer the possibility of immediate integration of major cloud computing providers. This model also offers a novel way to set up lightweight compute sites, without the need of setting up a Grid stack.
During the last year we have been running several queues at clusters...
