Components are the installable parts of the Cloud SDK. A component can be a
command-line tool (gcloud, bq and gsutil), a set of
gcloud tool commands at the Alpha or Beta
release levels, or a package
that contains dependencies used by a tool in the Cloud SDK.
The most commonly-used components are installed by default. If you run a
gcloud alpha or gcloud beta command interactively and the alpha or beta
component is not installed, the gcloud tool asks you whether you
want to install it. An affirmative response installs the component and then runs
the command. Other components are installed on-demand by the
gcloud tool when you run commands that require them.

Get started for freeDefault components
When you install the Cloud SDK, the following components are installed by default:
| ID | Name | Description |
|---|---|---|
gcloud |
Default gcloud tool commands |
Tool for interacting with Google Cloud. Only commands
at the General Availability and Preview release levels are installed with
this component. You must separately install the gcloud alpha
Commands and/or gcloud beta Commands components if you want to
use commands at other release levels. |
bq
| BigQuery command-line tool | Tool for working with data in BigQuery |
gsutil |
Cloud Storage command-line tool | Tool for performing tasks related to Cloud Storage. |
core |
Cloud SDK core libraries | Libraries used internally by the Cloud SDK tools. |
Alpha and beta components
The Cloud SDK provides two components that contain
gcloud tool alpha and beta commands. These components aren't
installed by default, but you can install them manually at any time after the
initial Cloud SDK installation. These components are:
| ID | Name | Description |
|---|---|---|
alpha |
gcloud tool alpha commands |
gcloud tool commands at the alpha release level. |
beta |
gcloud tool beta commands |
gcloud tool commands at the beta release level. |
gcloud tool commands at the General Availability release level are
part of the gcloud tool component and are installed automatically
when you install the Cloud SDK.
A list of all available additional components and external package managers (not installed by default) is available below.
Managing Cloud SDK components
You can list, install, update, and remove Cloud SDK components to suit your needs.
Listing components
To see a list of components that are available and currently installed,
run gcloud components list:
gcloud components list
The following sample isn't a complete listing of all available components. To
view the latest component offerings, update your Cloud SDK
installation and then run
gcloud components list.

Installing components
To install a component at the current version of your Cloud SDK
installation, run
gcloud components install:
gcloud components install [COMPONENT-ID]
The gcloud tool installs the specified component.
For example, if you want to install the kubectl command:
gcloud components install kubectl
Updating components
Use the gcloud components update
command to update all installed components to the latest available version of
Cloud SDK:
gcloud components update
If you have an older version of Cloud SDK installed, the
gcloud tool updates all the installed components.
If you'd need to revert to a previously known good version, and installed the
Cloud SDK directly (outside of a package manager, including using the
interactive installer, static versions, Windows installer, or Homebrew), you
can use gcloud components update to revert to the specified version:
gcloud components update --version VERSION
For downgrading versions of Cloud SDK installed using a package
manager, refer to these instructions for specifying versions when downloading
using apt-get or yum.
Removing components
Use the gcloud components remove
command to remove a specified component by its ID:
gcloud components remove [COMPONENT-ID]
You can re-install a component using the gcloud components install command
at any time.
Additional components
Additional components that contain dependencies for gcloud tool
commands are also available in the Cloud SDK, but aren't installed by
default. For an exhaustive list of components, run
$ gcloud components list.
Additional components that can be installed are marked with the status
Not Installed.
External package managers
If you installed the Cloud SDK through the apt
or yum package managers, you can also install
additional Cloud SDK components using those same package managers. If your
package manager cannot find these packages, read the
installing with apt or
installing with yum guides to learn how to configure
https://packages.cloud.google.com/ as a package source.
