Introduction
In this section, we explain how to deploy Kubernetes workloads on the TFGrid using tfcmd.
Deploy
tfcmd deploy kubernetes [flags]
Required Flags
- name: name for the master node deployment also used for canceling the cluster deployment. must be unique.
- ssh: path to public ssh key to set in the master node.
Optional Flags
- master-node: node id master should be deployed on.
- master-farm: farm id master should be deployed on, if set choose available node from farm that fits master specs (default 1). note: master-node and master-farm flags cannot be set both.
- workers-node: node id workers should be deployed on.
- workers-farm: farm id workers should be deployed on, if set choose available node from farm that fits master specs (default 1). note: workers-node and workers-farm flags cannot be set both.
- ipv4: assign public ipv4 for master node (default false).
- ipv6: assign public ipv6 for master node (default false).
- ygg: assign yggdrasil ip for master node (default true).
- master-cpu: number of cpu units for master node (default 1).
- master-memory: master node memory size in GB (default 1).
- master-disk: master node disk size in GB (default 2).
- workers-number: number of workers nodes (default 0).
- workers-ipv4: assign public ipv4 for each worker node (default false)
- workers-ipv6: assign public ipv6 for each worker node (default false)
- workers-ygg: assign yggdrasil ip for each worker node (default true)
- workers-cpu: number of cpu units for each worker node (default 1).
- workers-memory: memory size for each worker node in GB (default 1).
- workers-disk: disk size in GB for each worker node (default 2).
Example:
$ tfcmd deploy kubernetes -n kube --ssh ~/.ssh/id_rsa.pub --master-node 14 --workers-number 2 --workers-node 14

Get
tfcmd get kubernetes <kubernetes>
kubernetes is the name used when deploying kubernetes cluster using tfcmd.
Example:
$ tfcmd get kubernetes examplevm

Cancel
tfcmd cancel <deployment-name>
deployment-name is the name of the deployment specified in while deploying using tfcmd.
Example:
$ tfcmd cancel kube
