Installation

pyvcloud requires Python 3. See sections below for installation on major OS distributions. Examples consistently use pip3 install --user to install Python 3 modules privately to each OS account. This command ensures proper operation when there are mixed Python versions. It also avoids changes to the default Python installation. Another approach is to use virtualenv (see below).

Note that there are a couple of confusing exceptions related to installing pip itself. In these cases you must use the name pip.

Pre-release and source installations are covered at the end of the page, so keep reading to experience life on the bleeding edge.

If you find a bug in these procedures please file an issue or submit a pull request as described in CONTRIBUTING.md.

Ubuntu

Ubuntu 16.04:

    $ sudo apt-get install python3-pip gcc -y
    $ pip3 install --user pyvcloud

Note: If you encounter wheel errors ensure your pip3 version is up to date. pip3 install --upgrade pip usually fixes them.

CentOS

    $ sudo yum update
    $ sudo yum install -y yum-utils
    $ sudo yum groupinstall -y development
    $ sudo yum -y install https://centos7.iuscommunity.org/ius-release.rpm
    $ sudo yum -y install python36u python36u-pip python36u-devel
    $ sudo easy_install-3.6 pip
    $ pip3 install --user pyvcloud

Photon OS

Photon OS minimal installs lack standard tools like pip3 and even ping, so you need to install a number of packages using tdnf. There are also differences between Photon 1 and 2 distributions, so setup differs.

Photon 1:

    $ tdnf install -y gcc glibc-devel glibc-lang binutils python3-devel linux-api-headers
    $ pip3 install --user pyvcloud

Photon 2:

    $ tdnf install -y build-essential python3-setuptools python3-tools python3-pip python3-devel
    $ pip3 install --user pyvcloud

Mac OS X

Open a Terminal and enter the commands listed below. Skip those that refer to a component already installed on your Mac.

Install Xcode Command Line Tools:

    $ xcode-select --install

Press Install and accept the license terms.

Install pip3:

    $ sudo easy_install pip

Install pyvcloud:

    $ pip3 install --user pyvcloud

Note: Python installations on Mac OS X sometimes have problems with library compatibilities. Here are known issues and fixes.

Newer Python versions including 3.6.4 may experience path issues or SSL cert failures when running pip3. To get past them ensure your path points to the installed Python executables and not just the links in /usr/local/bin. Also, ensure that the pbr module is up to date. Here is an example. Your installation location may vary, so check to be sure.

    $ export PATH=/Library/Frameworks/Python.framework/Versions/3.6/bin:$PATH
    $ pip3 install --user pbr

Older Mac OS X Python3 versions link with an outdated OpenSSL library, which may lead to failures. If you get SSL errors on login, try adding the following libraries, then run pip3 again.

    $ pip3 install --user urllib3 pyopenssl

Windows 10

Start by installng Python 3 using the latest Windows installer available from https://www.python.org/downloads/windows/ and ensure that python.exe is in the path.

Install pyvcloud and add to the PATH (needed for local installs):

    C:\Users\Administrator>pip3 install --user pyvcloud
    C:\Users\Administrator>set PATH=%PATH%;C:\Users\Administrator\AppData\Roaming\Python\Python36\Scripts

Administrator is just an example. Other accounts work as well.

Verify Installation

Run the system-info.py script in the examples directory:

    $ cd examples
    $ ./system-info.py 10.150.202.222 Org1 user1 mypassword
    Logging in: host=10.150.202.222, org=Org1, user=user1
    Fetching vCD installation info...
    Key: name Value: VMware vCloud Director
    Key: href Value: https://10.150.202.222/api/admin/
    Key: type Value: application/vnd.vmware.admin.vcloud+xml
    Logging out

The host, org, user, and password values should be specific to your vCD installation.

Installation with virtualenv

It is also possible to install pyvcloud in a virtualenv. Quick commands to do so:

    $ python3 -m venv $HOME/my_venv
    $ . $HOME/my_venv/bin/activate
    (my_venv) $ pip3 install pyvcloud

To terminate the virtual environment use the deactivate command. In this case we don't use the --user option as venv supplies its own location for packages. Adding the --user option may cause odd installation behavior on some platforms.

Upgrade

To upgrade an existing pyvcloud install, run:

    $ pip3 install --user pyvcloud --upgrade

Pre-releases

The commands described above install the current stable version of pyvcloud. To install a pre-release version, enter:

    $ pip3 install --user pyvcloud --pre

And to upgrade a pre-release:

    $ pip3 install --user pyvcloud --pre --upgrade

Installation from the current development version in GitHub:

    $ pip3 install --user git+https://github.com/vmware/pyvcloud.git

Install specific Github or published versions:

    $ pip3 install --user git+https://github.com/vmware/pyvcloud.git@19.1.0
    (or)
    $ pip3 install --user pyvcloud==19.1.0

Installation from Local Source Files

This is the standard installation for development. Clone the code and install from source.

    $ git clone https://github.com/vmware/pyvcloud.git
    $ cd pyvcloud
    $ python3 setup.py develop

Scripts will automatically pick up current pyvcloud source files including any changes you have made. Use of virtualenv is recommended to avoid polluting your regular Python installation.

Note: You may need additional libraries for pyvcloud development. The following command installs extra dev libraries required on Ubuntu 16.04.

    sudo apt-get install libxml2-dev libxslt-dev zlib1g-dev
