What are components?
Components are the installable parts of the SDK. A component can be a
command-line tool (gcloud, bq and gsutil), a set of gcloud CLI commands at
the Alpha or Beta release levels, or a package
that contains dependencies used by a tool in the 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 CLI 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 CLI when you run commands that
require them.
Default components
When you install the SDK, the following components are installed by default:
| ID | Name | Description |
|---|---|---|
gcloud |
Default gcloud CLI 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 Google BigQuery |
gsutil |
Cloud Storage Command-Line Tool | Tool for performing tasks related to Google Cloud Storage. |
core |
Cloud SDK Core Libraries | Libraries used internally by the SDK tools. |
Alpha and beta components
The SDK provides two components that contain gcloud CLI alpha and beta commands. These components are not installed by default, but you can install them manually at any time after the initial SDK installation. These components are:
| ID | Name | Description |
|---|---|---|
alpha |
gcloud CLI alpha commands | gcloud CLI commands at the alpha release level. |
beta |
gcloud CLI beta commands | gcloud CLI commands at the beta release level. |
gcloud CLI commands at the General Availability release level are part of the gcloud CLI component and are installed automatically when you install the 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 Google 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

Note, the output displayed above is not a complete listing of all available
components. To view the latest component offerings, update your Cloud SDK
installation and 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 CLI 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 command-line tool updates all the installed components.
If you'd need to revert to a previously known good version, and installed the
SDK directly (outside of a package manager, including via 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 via a package manager, refer to
these instructions for specifying versions when downloading via
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 various gcloud CLI commands
are also available in the SDK, but not installed by default. One can run
$ gcloud components list for an exhaustive
list of components. Additional components that can be installed will be 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.
