sed -i 's/enforcing/disabled/' /etc/selinux/config
[如果多次安裝的]
kubeadm reset
ifconfig cni0 down
ip link delete cni0
ifconfig flannel.1 down
ip link delete flannel.1
rm -rf /var/lib/cni/
-----------------------------------------
/etc/sysctl.d/k8s.conf
-----------------------------------------
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
net.ipv4.ip_forward = 1
-----------------------------------------
modprobe br_netfilter
sysctl -p /etc/sysctl.d/k8s.conf
-----------------------------------------
1.
kubeadm init --kubernetes-version=v1.15.2 --pod-network-cidr=10.244.0.0/16 --service-cidr=10.96.0.0/12 --ignore-preflight-errors=all
結果
kubeadm join 10.0.2.16:6443 --token ved5ph.by42vstizqb6xlb3 \
--discovery-token-ca-cert-hash sha256:6c4e88ebb479ca1ca426787e7a9d20c4c94d0760ff88e1c7199b732db01c67cd
2.[test002\test003]
已經裝過需要清理[kubeadm reset]
mkdir -p $HOME/.kube
cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
chown $(id -u):$(id -g) $HOME/.kube/config
3.
[https://www.linuxea.com/1934.html]
wget https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
vi kube-flannel.yml 增加網卡enp0s3
kubectl apply -f ./kube-flannel.yml
4.增加node
kubeadm join 10.0.2.16:6443 --token ved5ph.by42vstizqb6xlb3 \
--discovery-token-ca-cert-hash sha256:6c4e88ebb479ca1ca426787e7a9d20c4c94d0760ff88e1c7199b732db01c67cd
2.安裝jupyterhub
https://zero-to-jupyterhub.readthedocs.io/en/latest/
2.1 helm版本2.14.3（參考https://www.jianshu.com/p/200020e7a843）
先pull 鏡像到本地 gcr.io/kubernetes-helm/tiller v2.14.3
再登錄阿里hub賬號（google網絡問題初始化失敗）
helm init --upgrade -i gcr.io/kubernetes-helm/tiller:v2.14.3 --stable-repo-url https://kubernetes.oss-cn-hangzhou.aliyuncs.com/charts
