|
|
|
- Create a Kubernetes master node:
|
|
|
|
|
|
|
|
|
|
`kubeadm init`
|
|
|
|
|
|
|
|
|
|
- Bootstrap a Kubernetes worker node and join it to a cluster:
|
|
|
|
|
|
|
|
|
|
`kubeadm join --token {{token}}`
|
|
|
|
|
|
|
|
|
|
- Create a new bootstrap token with a TTL of 12 hours:
|
|
|
|
|
|
|
|
|
|
`kubeadm token create --ttl {{12h0m0s}}`
|
|
|
|
|
|
|
|
|
|
- Check if the Kubernetes cluster is upgradeable and which versions are available:
|
|
|
|
|
|
|
|
|
|
`kubeadm upgrade plan`
|
|
|
|
|
|
|
|
|
|
- Upgrade Kubernetes cluster to a specified version:
|
|
|
|
|
|
|
|
|
|
`kubeadm upgrade apply {{version}}`
|
|
|
|
|
|
|
|
|
|
- View the kubeadm ConfigMap containing the cluster's configuration:
|
|
|
|
|
|
|
|
|
|
`kubeadm config view`
|
|
|
|
|
|
|
|
|
|
- Revert changes made to the host by 'kubeadm init' or 'kubeadm join':
|
|
|
|
|
|
|
|
|
|
`kubeadm reset`
|
