Chapter 4. Managing IDE extensions
IDEs use extensions or plugins to extend their functionality, and the mechanism for managing extensions differs between IDEs.
4.1. Extensions for Microsoft Visual Studio Code - Open Source
To manage extensions, this IDE uses one of these Open VSX registry instances:
-
The embedded instance of the Open VSX registry that runs in the
plugin-registry
pod of OpenShift Dev Spaces to support air-gapped, offline, and proxy-restricted environments. The embedded Open VSX registry contains only a subset of the extensions published on open-vsx.org. This subset is customizable. - The public open-vsx.org registry that is accessed over the internet.
- A standalone Open VSX registry instance that is deployed on a network accessible from OpenShift Dev Spaces workspace pods.
The default is the embedded instance of the Open VSX registry.
4.1.1. Selecting an Open VSX registry instance
The default is the embedded instance of the Open VSX registry.
If the default Open VSX registry instance is not what you need, you can select one of the following instances:
-
The Open VSX registry instance at
https://open-vsx.org
that requires access to the internet. - A standalone Open VSX registry instance that is deployed on a network accessible from OpenShift Dev Spaces workspace pods.
Procedure
Edit the
openVSXURL
value in theCheCluster
custom resource:spec: components: pluginRegistry: openVSXURL: "<url_of_an_open_vsx_registry_instance>" 1
- 1
- For example:
openVSXURL: "https://open-vsx.org"
.
Tip-
To select the embedded Open VSX registry instance in the
plugin-registry
pod, useopenVSXURL: ''
. You can customize the list of included extensions. -
You can also point
openVSXURL
at the URL of a standalone Open VSX registry instance if its URL is accessible from within your organization’s cluster and not blocked by a proxy.
4.1.2. Adding or removing extensions in the embedded Open VSX registry instance
You can add or remove extensions in the embedded Open VSX registry instance. This results in a custom build of the Open VSX registry that can be used in your organization’s workspaces.
To get the latest security fixes after a OpenShift Dev Spaces update, rebuild your container based on the latest tag or SHA.
Procedure
Get the publisher and extension names of each chosen extension:
- Find the extension on the Open VSX registry website and copy the URL of the extension’s listing page.
Extract the <publisher> and <extension> names from the copied URL:
https://www.open-vsx.org/extension/<publisher>/<extension>
TipIf the extension is only available from Microsoft Visual Studio Marketplace, but not Open VSX, you can ask the extension publisher to also publish it on open-vsx.org according to these instructions, potentially using this GitHub action.
If the extension publisher is unavailable or unwilling to publish the extension to open-vsx.org, and if there is no Open VSX equivalent of the extension, consider reporting an issue to the Open VSX team.
- Download or fork and clone the plugin registry repository.
Checkout the branch that corresponds to your OpenShift Dev Spaces version:
git checkout devspaces-$PRODUCT_VERSION-rhel-8
For each extension that you need to add or remove, edit the
openvsx-sync.json
file:-
To add extensions, add the publisher and extension names to the
openvsx-sync.json
file. -
To remove extensions, remove the publisher and extension names from the
openvsx-sync.json
file. Use the following JSON syntax:
{ "id": "<publisher>.<extension>" }
Tip-
The latest extension version on open-vsx.org is the default. Alternatively, you can add
"version": "<extension_version>"
on a new line to specify a version. If you have a closed-source extension or an extension developed only for internal use in your organization, you can add the extension directly from a
.vsix
file by using a URL accessible to your custom plugin registry container:{ "id": "<publisher>.<extension>", "download": "<url_to_download_vsix_file>", "version": "<extension_version>" }
- Read the Terms of Use for the Microsoft Visual Studio Marketplace before using its resources.

-
To add extensions, add the publisher and extension names to the
Build the plugin registry container image and publish it to a container registry like quay.io:
$ ./build.sh -o <username> -r quay.io -t custom
$ podman push quay.io/<username/plugin_registry:custom>
Edit the
CheCluster
custom resource in your organization’s cluster to point to the image (for example, on quay.io) and save the changes:spec: components: pluginRegistry: deployment: containers: - image: quay.io/<username/plugin_registry:custom> openVSXURL: ''
Verification
-
Check that the
plugin-registry
pod has restarted and is running. - Restart the workspace and check the available extensions in the Extensions view of the workspace IDE.
