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
4:21PM INF deploying network
4:22PM INF deploying cluster
4:22PM INF master yggdrasil ip: 300:e9c4:9048:57cf:504f:c86c:9014:d02d

Get

tfcmd get kubernetes <kubernetes>

kubernetes is the name used when deploying kubernetes cluster using tfcmd.

Example:

$ tfcmd get kubernetes examplevm
3:14PM INF k8s cluster:

Cancel

tfcmd cancel <deployment-name>

deployment-name is the name of the deployment specified in while deploying using tfcmd.

Example:

$ tfcmd cancel kube
