Installing Kubernetes

Usage of SINGA-Auto in Kubernetes mode requires Kubernetes 1.15+.

To achieve this, we recommend the instructions below:

  1. Install kubelet kubeadm kubectl

    apt-get install -y kubelet kubeadm kubectl --allow-unauthenticated

  2. Close swap

    swapoff -a

  3. Config cri and change docker mode to systemd, reference to Kubernetes Container runtimes

  4. Edit /etc/default/kubelet

    Environment= KUBELET_EXTRA_ARGS=–cgroup-driver=systemd

  5. Reset kubeadm, maybe not necessary

    kubeadm reset

  6. Init k8s service, use your own host ip and the node name you want

    kubeadm init --kubernetes-version=1.15.1 --pod-network-cidr=10.244.0.0/16 --apiserver-advertise-address=YOURHOSTIP --node-name=YOURNODENAME --ignore-preflight-errors=ImagePull

  7. Add Kubernetes config to current user

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

  8. If just a single node, set master node as worker node

    kubectl taint nodes --all node-role.kubernetes.io/master-

  9. Install flannel from github

    kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

  10. Config role

    kubectl create clusterrolebinding add-on-cluster-admin --clusterrole=cluster-admin --serviceaccount=default:default

  11. Nodeport range setting

    sudo vim /etc/kubernetes/manifests/kube-apiserver.yaml

    set “- –service-node-port-range=1-65535” in spec.containers.command node
