Che-Theia Plugins view support for DevWorkspace based workspaces

[vitaliy-guliy]

Is your task related to a problem? Please describe

The existing functionality that installing a plugin adds a component to the devfile

components:
  - type: chePlugin
    id: che-incubator/typescript/latest
    ...

It works only for devfile V1 workspaces, but does not work for Devfile V2 as it's completely different.

To add vscode extension to devfile V2 workspace it needs to add the extension ID to .vscode/extensions.json as in the example
https://github.com/che-samples/java-spring-petclinic/blob/devfilev2/.vscode/extensions.json

It's not a big deal for plugins, that are running in the same container withing Che-Theia. It's possible to take an extension ID or even URI (if it works) and add it to extensions.json.

But it needs to be discusses as well what shall we do with plugins, that are running inside separate container.

Describe the solution you'd like

Find a way to install a plugin from che-pluin-registry to devfile V2 workspace.

Release Notes Text

@vitaliy-guliy it's working as well for plug-ins with sidecars if you add their ids in .vscode/extensions.json (or in .che/che-theia-plugins.yaml)

Hi, a question to the assignee of this issue:

Will the outcome require any changes to the relevant content of the Installation Guide or Administration Guide or End-user Guide?

Yes/No?

[vitaliy-guliy]

@max-cx I think we don't need to change any documentation

[vitaliy-guliy]

To have the perfect UX flow we need to have

• fixed restarting the workspace after updating the devfile [devworkspace] Impossible to start the workspace after updating the devfile, using che-theia::k8s-devfile-service #20910
• somehow avoid the workspace autorestart when changing the devfile Allow to update the devfile V2 without automatically restarting the workspace #20920. In the devfile v2 we inject all the plugins, that are running in the sidecar, into developer container.
• allow to restart the workspsace on demand to ally the changes It should be able to restart devfile V2 workspace on demand #20921
