Requirements: TODO

• see Installing kubeadm (see specific instructions for your OS here)
• run kubeadm init to create configuration (only on new nodes before joining cluster)

1. sudo su -
2. systemctl enable kubelet && systemctl start kubelet
3. echo '1' > /proc/sys/net/bridge/bridge-nf-call-iptables

• sudo swapoff -a (or for permanent solution:)
• sudo vi /etc/fstab and edit out swap drive`

1. sudo iptables -I INPUT -p tcp -m tcp --dport 6443 -j ACCEPT (NB: may need OVERRIDE rule, depending on policy)
2. sudo /sbin/service iptables save
3. sudo service iptables restart

1. sudo iptables -I INPUT -p tcp -m tcp --dport 10250 -j ACCEPT (NB: may need OVERRIDE rule, depending on policy)
2. sudo /sbin/service iptables save 3 sudo service iptables restart

On node you wish to limit resources used by kubernetes, add --system-reserved=cpu=500m,memory=1Gi to the file /etc/systemd/system/kubelet.service.d/10-kubeadm.conf`

• see Creating a single master cluster for details

(Install details here)

1. kubeadm init --pod-network-cidr=192.168.0.0/16 (initialize)
2. kubectl apply -f https://docs.projectcalico.org/v3.3/getting-started/kubernetes/installation/hosted/rbac-kdd.yaml
3. kubectl apply -f https://docs.projectcalico.org/v3.3/getting-started/kubernetes/installation/hosted/kubernetes-datastore/calico-networking/1.7/calico.yaml

-- for calico cni (to be done on all nodes post installation of Calico) --

1. sudo iptables -I cali-failsafe-in -p tcp --match multiport --dport 179 -j ACCEPT
2. sudo /sbin/service iptables save
3. sudo service iptables restart

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

1. run command returned by kubeinit (sudo kubeadm join (token and csr output here)) with token output on all nodes to join

• to add new nodes in existing cluster: kubeadm token create --print-join-command

1. kubectl get nodes
2. kubectl drain <node name> --delete-local-data --force --ignore-daemonsets

1. kubectl delete node <node name>
2. kubeadm reset (do on node)

1. kubectl get nodes --show-labels
2. kubectl label --overwrite=true nodes atlas0.ahc.umn.edu node=atlas0 # add label

• Add example workflows
• Monitoring commands (get/describe/top/etc.)
