mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config

# Apply Network
sysctl net.bridge.bridge-nf-call-iptables=1
export kubever=$(kubectl version | base64 | tr -d '\n')
kubectl apply -f "https://cloud.weave.works/k8s/net?k8s-version=$kubever"

Debug Cycle

./debug.sh
# This script builds new images from the latest code, pushes it to the local
# docker registry, and then tries to create a new pod of a single grading using :
# kube_specs/vizdoom2018_grading_pod.yaml
# This also copies over the modified version of VizDoom and setups up run script
# to install VizDoom from this version instead.
#
# and then check logs of the host or submission pod by :
# kubectl logs vizdoom2018-grading-pod-debug -c host -f
# or
# kubectl logs vizdoom2018-grading-pod-debug -c submission -f
