Introduction

In this section, we explore how to deploy a virtual machine (VM) on the ThreeFold Grid using tfcmd.

Deploy

You can deploy a VM with tfcmd using the following template accompanied by required and optional flags:

tfcmd deploy vm [flags]

Flags

When you use tfcmd, there are two required flags (name and ssh), while the other remaining flags are optional. Using such optional flags can be used to deploy a VM with a GPU for example or to set an IPv6 address and much more.

Required Flags

• name: name for the VM deployment also used for canceling the deployment. The name must be unique.
• ssh: path to public ssh key to set in the VM.

Optional Flags

• node: node ID the VM should be deployed on.
• farm: farm ID the VM should be deployed on, if set choose available node from farm that fits vm specs (default 1). Note: node and farm flags cannot both be set.
• cpu: number of cpu units (default 1).
• disk: size of disk in GB mounted on /data. If not set, no disk workload is made.
• entrypoint: entrypoint for the VM FList (default /sbin/zinit init). Note: setting this without the flist option will fail.
• flist: FList used in the VM (default https://hub.grid.tf/tf-official-apps/threefoldtech-ubuntu-22.04.flist). Note: setting this without the entrypoint option will fail.
• ipv4: assign public ipv4 for the VM (default false).
• ipv6: assign public ipv6 for the VM (default false).
• memory: memory size in GB (default 1).
• rootfs: root filesystem size in GB (default 2).
• ygg: assign yggdrasil ip for the VM (default true).
• gpus: assign a list of gpus' IDs to the VM. Note: setting this without the node option will fail.

Examples

We present simple examples on how to deploy a virtual machine with or without a GPU using tfcmd.

Deploy a VM without GPU

$ tfcmd deploy vm --name examplevm --ssh ~/.ssh/id_rsa.pub --cpu 2 --memory 4 --disk 10
12:06PM INF deploying network
12:06PM INF deploying vm
12:07PM INF vm yggdrasil ip: 300:e9c4:9048:57cf:7da2:ac99:99db:8821

Deploy a VM with GPU

$ tfcmd deploy vm --name examplevm --ssh ~/.ssh/id_rsa.pub --cpu 2 --memory 4 --disk 10 --gpus '0000:0e:00.0/1882/543f' --gpus '0000:0e:00.0/1887/593f' --node 12
12:06PM INF deploying network
12:06PM INF deploying vm
12:07PM INF vm yggdrasil ip: 300:e9c4:9048:57cf:7da2:ac99:99db:8821

Get

To get the VM, use the following template:

tfcmd get vm <vm>

Make sure to replace <vm> with the name of the VM specified using tfcmd.

Get Example

In the following example, the name of the deployment to get is examplevm.

$ tfcmd get vm examplevm
3:20PM INF vm:

Cancel

To cancel your VM deployment, use the following template:

tfcmd cancel <deployment-name>

Make sure to replace <deployment-name> with the name of the deployment specified using tfcmd.

Cancel Example

In the following example, the name of the deployment to cancel is examplevm.

$ tfcmd cancel examplevm
3:37PM INF canceling contracts for project examplevm
3:37PM INF examplevm canceled
