node-status | Nodejs stdout status and progress bar | Runtime Evironment library

I am having test environment cluster with 1 master and two worker node, all the basic pods are up and running.

I have a task running on an EC2 cluster which starts to slow down progressively as virtual CPUs are employed (regardless of EBS volume size). To avoid this I want to disable hyperthreading on all nodes and was trying to implement the advice given here: https://aws.amazon.com/blogs/compute/disabling-intel-hyper-threading-technology-on-amazon-linux/.
I am using Ray to launch the cluster in Ubuntu 18.04, and assumed that the initialization_commands section in the config.yaml file is the appropriate place to implement the bash commands (the bootcmd: heading is not understood there). I have tried a number of different formats but none seem to work; e.g.:-

I am using the Ray module to launch an Ubuntu (16.04) cluster on AWS EC2. In the configuration I specified min_workers, max_workers and initial_workers as 2, because I do not need any auto-sizing. I also want a t2.micro master-node and c4.8xlarge workers. The cluster launches, but only the master (the following terminal output is from the ray installation onwards, .... minus details):-

I have setup a K8S cluster (1 master and 2 slaves) using Kubeadm on my laptop.

• Deployed 6 replicas of a pod. 3 of them got deployed to each of the slaves.
• Did a shutdown of one of the slave.
• It took ~6 minutes for the 3 pods to be scheduled on the running node.

Initially, I thought that it had to do something with the K8S setup. After some digging found out, it's because of the defaults in the K8S for Controller Manager and Kubelet as mentioned here. It made sense. I checked out the K8S documentation on where to change the configuration properties and also checked the configuration files on the cluster node, but couldn't figure it out.

I'm trying to go on my angular 2 webapp but I get this error on each page :

I haven't changed anything in the app, and it works on computers of people of my team.

Is it caused by these warnings when npm install ?
