Photon Go Cli

The repo for the Photon go cli.

Setup

The project requires go version 1.6+. You can download and install go from: https://golang.org/dl/

Decide a folder as the GOPATH, e.g. ~/go.

1. mkdir -p ~/go/src/github.com/vmware/
2. cd ~/go/src/github.com/vmware/
3. git clone (this repo from gerrit or github)
4. cd photon-controller-cli
5. export GOPATH=~/go
6. export PATH=$PATH:~/go/bin
7. make tools

Build and Test

To run the test:

  make test

To build the executables:

  make build

The executables are generated under photon-controller-cli/bin folder.

To run and verify the CLI:

   ./bin/photon -v

Pick up Changes from SDK

When there are changes in SDK, wait for them promoted to master branch on github.com.

Follow the steps below:

1. go get -u github.com/vmware/photon-controller-go-sdk/photon
2. govendor update github.com/vmware/photon-controller-go-sdk/...

Before comitting the change, carefully inspect the changes to Godeps, for example with git diff or SourceTree.

Then you can commit and submit the change.

Example Usage

Notes:

  • Commands below are shown as you type-them. The "%" indicates a command-line prompt.
  • These are illustrative examples. Not all commands or parameters are described.

Getting help

The photon CLI includes extensive usage description that you can use to discover various operations.

For instance, you can see the top-level commands with:

% photon help

Interactive vs. Non-interactive mode

All commands work in two mode: interactive and non-interactive. Interactive mode will prompt you for parameters you do not provide on the command-line and will print human-readable output. Non-interactive mode will not prompt you and will print machine-readable output.

IDs

Objects in Photon Controller are given unique IDs, and most commands refer to them using those IDs.

Setting a target

Before you can use the photon CLI, you need to tell it which Photon Controller to use.

Usage: photon target set <PHOTON-CONTROLLER-URL>

Example:

% photon target set -c https://198.51.100.41
API target set to 'https://198.51.100.41'

If you are not using HTTPS, specify the port:

% photon target set http://198.51.100.41:9000
API target set to 'http://198.51.100.41:9000'

Tenants

Creating a tenant will tell you the ID of the tenant:

Usage: photon tenant create <TENANT-NAME>

Example:

% photon -n tenant create cloud-dev
cloud-dev	502f9a79-96b6-451d-bfb9-6292ca5b6cfd

You can list all tenants:

% photon -n tenant list
502f9a79-96b6-451d-bfb9-6292ca5b6cfd	cloud-dev

Set tenant for other commands

Many commands take a --tenant parameter because the object in question is owned by a tenant. As a convenience, you can avoid passing that parameter, you can set the tenant for future commands:

Usage: photon tenant set <TENANT-NAME>

Example:

% photon tenant set cloud-dev
Tenant set to 'cloud-dev'

The tenant will be stored in a configuration file in your home directory, within a subdirectory named .photon-config.

You can see what the current tenant is:

% photon tenant get
Current tenant is 'cloud-dev' 502f9a79-96b6-451d-bfb9-6292ca5b6cfd

Quota

You assign quota to control the resource allocations granted to tenants and projects.

A quota must specify the number of VMs that can be created as well as the total amount of RAM consumed by those VMs. If a flavor is used for VM creation, all of its costs must be in the quota including ephemeral and persistent disk capacities. It's possible to have user-defined quota as well. These are specified as comma-separated limits, and each limit is a set of three things:

  • Name (e.g. vm.memory)
  • Value (e.g. 2000)
  • Units (GB, MB, KB, COUNT)

Creating a tenant with quota assigned (see above, or use the --tenant flag):

Usage photon tenant create cloud-dev --limits "<LIMITS>"

Example:

% photon -n tenant create --name cloud-dev
         --limits "vm.memory 2000 GB, vm 1000 COUNT, ephemeral-disk.capacity 2000 GB"
32ad527e-d21a-4b2a-a235-b0883bd64354

Creating a tenant with user-defined resources:

% photon -n tenant create --name cloud-dev
         --limits "vm.memory 2000 GB, vm 1000 COUNT, ephemeral-disk.capacity 2000 GB, vm.potrzebie 250 COUNT"
32ad527e-d21a-4b2a-a235-b0883bd64354

Projects

A project is owned by a tenant and all VMs are created within a project. Each project is assigned with a quota that controls the total resources that can be used. See above for more information about quota.

A project has a set of limits. These are specified just like the quota above, but they must not exceed the limits in the tenant.

Creating a project:

Usage: photon project create <PROJECT-NAME> --limits <LIMITS>

% photon -n project create cloud-dev-staging --limits "vm.memory 1000 GB, vm 500 COUNT"
fabb9236-d0a4-4d30-8935-ee65d6729f78

Viewing projects:

% photon -n project list
fabb9236-d0a4-4d30-8935-ee65d6729f78 cloud-dev-staging vm.memory:1000:GB,vm:500:COUNT vm.memory:0:GB,vm:0:COUNT

Setting the project (applies to commands that require a project, like creating a VM). If you prefer, you can pass the --project flag:

% photon -n project set cloud-dev-staging

Flavors

When a VM is made, it is described using two kinds of flavors: VM and disk. The flavors describes how many resources are consumed by the VM from the resource ticket.

The cost argument specifies a set of costs, each separated by commas. Each cost consists of three value:

  • Name
  • Value, which will be subtracted from the resource ticket when the VM is created
  • Units: GB, MB, KB, B, or COUNT

Note that VM flavors must specify at least the vm.cpu and vm.memory costs. Other user-defined costs may be included as well, if desired. They should match the resources in the resource ticket.

Creating a VM flavor with with 1 VM, 1 CPU and 2 GB RAM:

Usage: photon flavor create --name <FLAVOR-NAME> --kind <KIND> --cost <COST>

Example:

% photon -n flavor create --name "cloud-vm-small" --kind "vm"
         --cost "vm 1.0 COUNT, vm.cpu 1.0 COUNT, vm.memory 2.0 GB"
ddfb5be0-3355-46d3-9f2f-e28750eb201b

Creating a VM flavor with user-defined attributes:

% photon -n flavor create --name "cloud-vm-small" --kind "vm"
         --cost "vm 1.0 COUNT, vm.cpu 1.0 COUNT, vm.memory 2.0 GB vm.potrzebie 10"
ddfb5be0-3355-46d3-9f2f-e28750eb201b

Creating a disk flavor:

% photon -n flavor create --name "cloud-disk"
         --kind "ephemeral-disk" --cost "ephemeral-disk 1.0 COUNT"
78efc53a-88ce-4f09-9b5d-49662d21e56c

  Cost:  [vm 1 COUNT vm.cpu 1 COUNT vm.memory 2 GB]
  State: READY

Images

Uploading an image (OVA, OVF, or VMDK). The replication type is either EAGER or ON_DEMAND

Usage: photon image create <IMAGE-FILENAME> -n <IMAGE-NAME> -i <TYPE>

Example:

% photon image create photon.ova -n photon-os -i EAGER
Created image 'photon-os' ID: 8d0b9383-ff64-4112-85db-e8111e2269fc

VMs

When you create a VM, you must specify both the VM and disk flavors. The disks parameter lists a set of disks, separated by commas. Each disk is described by three values:

  • name
  • flavor
  • Either "boot=true" or a size in GB for the disk

Usage: photon -n vm create --name <VM-NAME> --image <IMAGE-ID> --flavor <VM-FLAVOR> --disk <DISK-DESCRIPTION>

% photon -n vm create --name vm-1 --image 8d0b9383-ff64-4112-85db-e8111e2269fc
         --flavor cloud-vm-small --disks "disk-1 cloud-disk boot=true"
