README

govmomi

A Go library for interacting with VMware vSphere APIs (ESXi and/or vCenter).

In addition to the vSphere API client, this repository includes:

• govc - vSphere CLI

• vcsim - vSphere API mock framework

• toolbox - VM guest tools framework

Compatibility

This library is built for and tested against ESXi and vCenter 6.5, 6.7 and 7.0.

It may work with versions 5.1, 5.5 and 6.0, but neither are officially supported.

Documentation

The APIs exposed by this library very closely follow the API described in the VMware vSphere API Reference Documentation. Refer to this document to become familiar with the upstream API.

The code in the govmomi package is a wrapper for the code that is generated from the vSphere API description. It primarily provides convenience functions for working with the vSphere API. See godoc.org for documentation.

Installation

govmomi (Package)

go get -u github.com/vmware/govmomi

Binaries and Docker Images for govc and vcsim

Installation instructions, released binaries and Docker images are documented in the respective README files of govc and vcsim.

Discussion

Contributors and users are encouraged to collaborate using GitHub issues and/or Slack. Access to Slack requires a VMware {code} membership.

Status

Changes to the API are subject to semantic versioning.

Refer to the CHANGELOG for version to version changes.

Documentation

Overview

This package is the root package of the govmomi library.

The library is structured as follows:

Package vim25

The minimal usable functionality is available through the vim25 package. It contains subpackages that contain generated types, managed objects, and all available methods. The vim25 package is entirely independent of the other packages in the govmomi tree -- it has no dependencies on its peers.

The vim25 package itself contains a client structure that is passed around throughout the entire library. It abstracts a session and its immutable state. See the vim25 package for more information.

Package session

The session package contains an abstraction for the session manager that allows a user to login and logout. It also provides access to the current session (i.e. to determine if the user is in fact logged in)

Package object

The object package contains wrappers for a selection of managed objects. The constructors of these objects all take a *vim25.Client, which they pass along to derived objects, if applicable.

Package govc

The govc package contains the govc CLI. The code in this tree is not intended to be used as a library. Any functionality that govc contains that _could_ be used as a library function but isn't, _should_ live in a root level package.

Other packages

Other packages, such as "event", "guest", or "license", provide wrappers for the respective subsystems. They are typically not needed in normal workflows so are kept outside the object package.

Types

type Client

type Client struct {
	*vim25.Client

	SessionManager *session.Manager
}

func NewClient

func NewClient(ctx context.Context, u *url.URL, insecure bool) (*Client, error)

NewClient creates a new client from a URL. The client authenticates with the server with username/password before returning if the URL contains user information.

func (*Client) IsVC

func (c *Client) IsVC() bool

IsVC returns true if we are connected to a vCenter

func (*Client) Login

func (c *Client) Login(ctx context.Context, u *url.Userinfo) error

Login dispatches to the SessionManager.

func (*Client) Logout

func (c *Client) Logout(ctx context.Context) error

Logout dispatches to the SessionManager.

func (*Client) PropertyCollector

func (c *Client) PropertyCollector() *property.Collector

PropertyCollector returns the session's default property collector.

func (*Client) Retrieve

func (c *Client) Retrieve(ctx context.Context, objs []types.ManagedObjectReference, p []string, dst interface{}) error

Retrieve dispatches to the Retrieve function on the default property collector.

func (*Client) RetrieveOne

func (c *Client) RetrieveOne(ctx context.Context, obj types.ManagedObjectReference, p []string, dst interface{}) error

RetrieveOne dispatches to the Retrieve function on the default property collector.

func (*Client) Wait

func (c *Client) Wait(ctx context.Context, obj types.ManagedObjectReference, ps []string, f func([]types.PropertyChange) bool) error

Wait dispatches to property.Wait.
