README

govc

govc is a vSphere CLI built on top of govmomi.

Installation

You can find prebuilt govc binaries on the releases page.

Download and install a binary locally like this:

curl -L $URL_TO_BINARY | gunzip > /usr/local/bin/govc
chmod +x /usr/local/bin/govc

Source

You can install the latest govc version from source if you have the Go toolchain installed.

go get github.com/vmware/govmomi/govc

(make sure $GOPATH/bin is in your PATH)

Usage

For the complete list of commands and flags, refer to the USAGE document.

Common flags include:

• -u: ESXi or vCenter URL (ex: user:pass@host)
• -debug: Trace requests and responses (to ~/.govmomi/debug)

Managed entities can be referred to by their absolute path or by their relative path. For example, when specifying a datastore to use for a subcommand, you can either specify it as /mydatacenter/datastore/mydatastore, or as mydatastore. If you're not sure about the name of the datastore, or even the full path to the datastore, you can specify a pattern to match. Both /*center/*/my* (absolute) and my*store (relative) will resolve to the same datastore, given there are no other datastores that match those globs.

The relative path in this example can only be used if the command can umambigously resolve a datacenter to use as origin for the query. If no datacenter is specified, govc defaults to the only datacenter, if there is only one. The datacenter itself can be specified as a pattern as well, enabling the following arguments: -dc='my*' -ds='*store'. The datastore pattern is looked up and matched relative to the datacenter which itself is specified as a pattern.

Besides specifying managed entities as arguments, they can also be specified using environment variables. The following environment variables are used by govc to set defaults:

• GOVC_URL: URL of ESXi or vCenter instance to connect to.

  The URL scheme defaults to https and the URL path defaults to /sdk. This means that specifying user:pass@host is equivalent to https://user:pass@host/sdk.

  If password include special characters like # or : you can use GOVC_USERNAME and GOVC_PASSWORD to have a simple GOVC_URL

  When using govc against VMware Workstation, GOVC_URL can be set to "localhost" without a user or pass, in which case local ticket based authentication is used.

• GOVC_USERNAME: USERNAME to use if not specified in GOVC_URL.

• GOVC_PASSWORD: PASSWORD to use if not specified in GOVC_URL.

• GOVC_TLS_CA_CERTS: Override system root certificate authorities.

  export GOVC_TLS_CA_CERTS=/.govc_ca.crt Use path separator to specify multiple files: export GOVC_TLS_CA_CERTS=/ca-certificates/bar.crt:~/ca-certificates/foo.crt

• GOVC_TLS_KNOWN_HOSTS: File(s) for thumbprint based certificate verification.

  Thumbprint based verification can be used in addition to or as an alternative to GOVC_TLS_CA_CERTS for self-signed certificates. Example: export GOVC_TLS_KNOWN_HOSTS=~/.govc_known_hosts govc about.cert -u host -k -thumbprint | tee -a $GOVC_TLS_KNOWN_HOSTS govc about -u user:pass@host

• GOVC_INSECURE: Disable certificate verification.

  This option sets Go's tls.Config.InsecureSkipVerify flag and is false by default. Quoting https://golang.org/pkg/crypto/tls/#Config:

  InsecureSkipVerify controls whether a client verifies the server's certificate chain and host name. If InsecureSkipVerify is true, TLS accepts any certificate presented by the server and any host name in that certificate. In this mode, TLS is susceptible to man-in-the-middle attacks. This should be used only for testing.

• GOVC_DATACENTER

• GOVC_DATASTORE

• GOVC_NETWORK

• GOVC_RESOURCE_POOL

• GOVC_HOST

• GOVC_GUEST_LOGIN: Guest credentials for guest operations

• GOVC_VIM_NAMESPACE: Vim namespace defaults to urn:vim25

• GOVC_VIM_VERSION: Vim version defaults to 6.0

Examples

Several examples are embedded in the govc command help

• Upload ssh public key to a VM

• Create and configure a vCenter VM

• Create a CoreOS VM

• Create a Debian VM

• Create a Windows VM

• Create an ESX VM

• Create a vCenter VM

• Create a Cluster

Status

Changes to the cli are subject to semantic versioning.

Refer to the CHANGELOG for version to version changes.

When new govc commands or flags are added, the PATCH version will be incremented. This enables you to require a minimum version from within a script, for example:

govc version -require 0.7.1

Projects using govc

• Emacs govc package
