vss-cli

ITS Private Cloud Command Line Interface vss-cli

The ITS Private Cloud Command-Line Interface vss-cli simplifies the interaction with the [ITS Private Cloud API][ITS Private Cloud API] to manage your virtual machines and other services.

Documentation

Package documentation is now available at docs.

Installation

Windows users, follow the installation instructions [Installing Python on Windows][Installing Python on Windows] and add %USERPROFILE%\AppData\Roaming\Python\Python37\Scripts to PATH environment variable prior running pip.

PIP

The fastest way to install VSS CLI is to use pip:

pip install vss-cli

If you are planning to interact with vskey-stor execute the following command

pip install 'vss-cli[stor]'

The command will install minio package from PyPI.

Windows users, please install windows-curses and vss-cli as follows: pip install --user vss-cli windows-curses.

If you have the VSS CLI installed and want to upgrade to the latest version you can run:

pip install --upgrade vss-cli

Homebrew

Use Homebrew to install the vss-cli on macOS:

brew tap vss/vss-cli https://github.com/EIS-ITS/vss-cli
brew install vss-cli

Using Homebrew will automatically setup autocompletion based on your current shell.

From Source

You can also just download the tarball. Once you have the vss-cli directory structure on your workstation, you can just run:

cd path_to_vss-cli
python setup.py install

Docker

If you do not have a Python setup you can try using vss-cli via a container using Docker.

docker run uofteis/vss-cli

docker-vss-cli is a helpful script to run the vss-cli within a docker container. Just download or move the file and update the environment variables if required, give execution permission and move it to your $PATH:

# U of T
curl https://gitlab-ee.eis.utoronto.ca/vss/vss-cli/raw/main/docker/docker-vss-cli > vss-cli
chmod +x vss-cli

# Public
curl https://raw.githubusercontent.com/EIS-ITS/vss-cli/main/docker/docker-vss-cli > vss-cli
chmod +x vss-cli

CLI Releases

The release notes for the VSS CLI can be found CHANGELOG in the gitlab repo.

Getting Started

Before using VSS CLI, you need setup your VSS credentials. You can do this in a couple of ways:

• Configuration file
• Environment variables
• Command Line Input

The quickest way to get started is to run the vss-cli configure mk command:

vss-cli configure mk

Endpoint [https://cloud-api.eis.utoronto.ca]: 
Username: jm
Password: 
Repeat for confirmation: 

To use environment variables, set VSS_USER and VSS_USER_PASS or VSS_TOKEN:

export VSS_USER=USER
export VSS_USER_PASS=superstrongpassword
# or
export VSS_TOKEN=JWT_TOKEN

For detailed information about the vss-cli configuration, please refer to the official documentation site.

JSON/YAML Parameter Input

VSS CLI options vary from simple string, boolean, numeric values, JSON data structures and file in both JSON and YAML as input parameters on the command line.

For example, consider the following command to deploy a new virtual machine from a given template and provide a guest operating system specification to reconfigure hostname, domain, dns, ip, subnet and gateway:

vss compute vm mk from-template --source VM-Template \
      --description 'New virtual machine' \
      --custom-spec '{"hostname": "fe1", "domain": "eis.utoronto.ca", "interfaces": [{"dhcp": true}]}'

However, if a file is provided instead with a JSON or YAML structure, the CLI will take it as valid such as new-vm-custom-spec.json or new-vm-custom-spec.yaml shown below:

{
  "hostname": "fe1",
  "domain": "eis.utoronto.ca",
  "interfaces": [
    {
      "dhcp": true
    }
  ]
}

or

hostname: fe1
domain: eis.utoronto.ca
interfaces:
  - dhcp: true

vss compute vm mk from-template --source VM-Template \
      --description 'New virtual machine' \
      --custom-spec new-vm-custom-spec.json

Auto-completion

Bash completion support is provided by Click and will complete sub commands and parameters. Sub commands are always listed whereas parameters only if at least a dash has been provided. Example:

vss-cli compute <TAB><TAB>
account    compute    configure  request    stor       token

vss-cli -<TAB><TAB>
--config      --no-verbose  --output      --verbose     --version     -c            -o

Activating bash or zsh completion can be done by executing the following commands:

For bash:

source <(vss-cli completion bash)

For zsh:

source <(vss-cli completion zsh)

For fish

_VSS_CLI_COMPLETE=fish_source vss-cli > ~/.config/fish/completions/vss-cli-complete.fish

If you do it from your .bashrc or .zshrc it is recommended to use the following method since avoids triggering a run of vss-cli itself.

For bash:

eval "$(_VSS_CLI_COMPLETE=bash_source vss-cli)"

For zsh:

eval "$(_VSS_CLI_COMPLETE=zsh_source vss-cli)"

For fish:

eval (env _VSS_CLI_COMPLETE=fish_source vss-cli)

VSS Shell

The VSS CLI provides a REPL interactive shell with tab-completion, suggestions and command history.

Usage: vss shell [OPTIONS]

  REPL interactive shell.

Options:
  -i, --history TEXT  File path to save history
  --help              Show this message and exit.

To enter the shell just execute vss shell and you will get the following welcome message:

    __   _____ ___
    \ \ / / __/ __|      API Endpoint: https://cloud-api.eis.utoronto.ca/v2
     \ V /\__ \__ \      Tab-completion & suggestions
      \_/ |___/___/      Prefix external commands with "!"
       CLI v20xx.0.0      History is saved: /Users/user/.vss-cli/history

    Exit shell with :exit, :q, :quit, ctrl+d
