Deploy Code-OSS (https://github.com/microsoft/vscode) on a Kubernetes cluster and connect with your Browser.

This repository is hosting the changes to have the Code-OSS running inside a browser and connecting to a remote HTTP(s) server (instead of using desktop mode).

The terminal is aware of the running pod. Then, you can open terminals in every container of the running pod (if the containers have shell access).

Upstream Code-OSS is stored using Git subtree. It means that if you're not interested in updating/rebasing upstream code you don't need to setup anything else unlike git submodules. This repository is self-contained.

Development pre-requisites

NodeJS version used by Code-OSS (Exact version can be find inside https://github.com/microsoft/vscode/blob/main/remote/.npmrc with target property)
npm

Directories layout

code contains the upstream content (subtree) + changes required to have Code running in a remote server.
build/dockerfiles are for building a container.
package.json holds some top-level scripts that you can find also in the code folder.

Development mode

Fetch dependencies with npm install command
Compile and watch folders: npm run watch
Run the server (another terminal for example): npm run server

Image build

docker build -f build/dockerfiles/linux-musl.Dockerfile -t linux-musl-amd64 .
docker build -f build/dockerfiles/linux-libc-ubi8.Dockerfile -t linux-libc-ubi8-amd64 .
docker build -f build/dockerfiles/linux-libc-ubi9.Dockerfile -t linux-libc-ubi9-amd64 .
export DOCKER_BUILDKIT=1
docker build -f build/dockerfiles/assembly.Dockerfile -t che-code .

Developing with Eclipse Che®

This project includes Devfile that simplifies developing Che-Code in Eclipse Che. To test your changes in Eclipse Che run the following VS Code tasks:

prepare to download all the required dependencies
build to pre-build and start the watch mode
run to run the VS Code server
Follow the suggested URL to test your changes.

Updates and branches

This repository has a main branch being rebased on the main remote branch of Code-OSS. Then, for each stable version of Code-OSSthere is a matching branch. For example remote release/1.60 is handled locally as a 1.62.x branch.

Pulling/Diff against new Code OSS version - useful commands

Add the Code-OSS remote by using for example the following command:

$ git remote add upstream-code https://github.com/microsoft/vscode

Pulling changes from upstream https://github.com/microsoft/vscode

For a release branch:

$ git subtree pull --prefix code upstream-code release/1.62

For the main branch:

$ git subtree pull --prefix code upstream-code main

Checking the diff between local and remote

For a release branch:

$ git diff upstream-code/release/1.62 1.62.x:code

For a main branch:

$ git diff upstream-code/main main:code

Fixing the `rebase-insiders` Workflow?

Upstream VS Code changes may bring a breakage to Che-Code. In this case, the rebase-insiders Workflow run is failed. To fix it, follow the steps below:

Checkout to a new branch, e.g.fix-rebase.
Fetch the latest changes from the upstream:

git remote add upstream-code https://github.com/microsoft/vscode
git fetch upstream-code main

./rebase.sh
Fix the conflicts or other errors. Note, that./rebase.sh script also applies the patches from the .rebase directory. Sometimes, it also requires some updates there.
Open a PR with your changes.

Branding the UI

You can brand some of the UI elements in the Visual Studio Code - Open Source IDE with your corporate or product brand.

This means first adding brand-related files to the forked IDE repository, then building a container image of the branded IDE, and finally adding a che-editor.yaml file to the project repository.

Here are some examples of the UI elements in Visual Studio Code - Open Source that you can brand:

Browser tab title and icon
The icon for the empty editor area when no editor is open
The Status Bar commands
The Status Bar icon
The Get Started page
The tab icon for the Get Started page
The application name in the About dialog

Prerequisites

Bash
docker

Procedure

1. Fork or download the Git repository of Visual Studio Code - Open Source IDE for Eclipse Che.

2. In the /branding/ folder of the repository, create the product.json file, which maps custom branding resources.

💡 In the product.json file, specify all paths relative the /branding/ folder.

Example. /branding/product.json

The following example shows all of the properties that you can customize by using this file:

{
    "nameShort": "Branded IDE",
    "nameLong": "Branded Instance of Eclipse Che with Branded Microsoft Visual Studio Code - Open Source IDE",
    "welcomePageTitle": "Branded Instance of Eclipse Che",
    "welcomePageSubtitle": "with Branded Microsoft Visual Studio Code - Open Source IDE",
    "icons": {
        "favicon": {
            "universal": "icons/favicon.ico"
        },
        "welcome": {
            "universal": "icons/icon.svg"
        },
        "statusBarItem": {
            "universal": "icons/icon.svg"
        },
        "letterpress": {
            "light": "icons/letterpress-light.svg",
            "dark": "icons/letterpress-light.svg"
        }
    },
    "remoteIndicatorCommands": {
        "openDocumentationCommand": "Branded IDE: Open Documentation",
        "openDashboardCommand": "Branded IDE: Open Dashboard",
        "openOpenShiftConsoleCommand": "Branded IDE: Open OpenShift Console",
        "stopWorkspaceAndRedirectToDashboard": "Branded IDE: Stop Workspace",
        "restartWorkspaceCommand": "Branded IDE: Restart Workspace",
        "restartWorkspaceFromLocalDevfileCommand": "Branded IDE: Restart Workspace from Local Devfile"
    },
    "workbenchConfigFilePath": "workbench-config.json",
    "codiconCssFilePath": "css/codicon.css"
}

nameShort is the application name for UI elements.

nameLong is the application name that is used for the Welcome page, About dialog, and browser tab title.

welcomePageTitle is the Welcome page title. The field is optional, the default is nameLong as the title.

welcomePageSubtitle - is the Welcome page subtitle. The field is optional, the default value comes from the upstream.

favicon is the icon for the browser tab title for all themes.

welcome is the icon for the tab title of the Get Started page for all themes.

statusBarItem is the icon for the bottom Status Bar for all themes. Define it as codicon in the workbench-config.json file and the codicon CSS styles.

letterpress is the icon for the empty editor area when no editor is open. You can provide different icon files for light and dark themes.

remoteIndicatorCommands is the names of commands provided by the Eclipse Che Remote extension. Users can run these commands by clicking the Status Bar.

workbenchConfigFilePath is the relative path to workbench-config.json, which is explained in one of the next steps.

codiconCssFilePath is the relative path to css/codicon.css, which is explained in one of the next steps.

❕ The values defined in the /branding/product.json file override the default values.

3. Add the icon files, which you specified in the product.json file in the previous step, to the repository.

4. Create a /branding/workbench-config.json file with custom values.

Example. /branding/workbench-config.json

{
	"windowIndicator": {
		"label": "$(eclipse-che) Branded IDE",
		"tooltip": "Branded IDE"
	},
	"configurationDefaults": {
		"workbench.colorTheme": "Dark",
		"workbench.colorCustomizations": {
			"statusBarItem.remoteBackground": "#FDB940",
			"statusBarItem.remoteForeground": "#525C86"
		}
	},
	"initialColorTheme": {
		"themeType": "dark",
		"colors": {
			"statusBarItem.remoteBackground": "#FDB940",
			"statusBarItem.remoteForeground": "#525C86"
		}
	}
}

eclipse-che in "label": "$(eclipse-che) Eclipse Che" is from span.codicon.codicon-eclipse-che in /branding/css/codicon.css in the next step.

5. Create a /branding/css/codicon.css file with custom values.

Example. /branding/css/codicon.css

span.codicon.codicon-eclipse-che  {
	background-image: url(./che/icon.svg);
	width: 13px;
	height: 13px;
}

6. Run the /branding/branding.sh script. The branding.sh script searches for the branding resources in the branding folder and applies the changes.

$ ./branding/branding.sh

7. Build the container image from the /che-code/ directory and push the image to a container registry:

$ docker build -f build/dockerfiles/linux-musl.Dockerfile -t linux-musl-amd64 .

$ docker build -f build/dockerfiles/linux-libc-ubi8.Dockerfile -t linux-libc-ubi8-amd64 .

$ docker build -f build/dockerfiles/linux-libc-ubi9.Dockerfile -t linux-libc-ubi9-amd64 .

$ export DOCKER_BUILDKIT=1

$ docker build -f build/dockerfiles/assembly.Dockerfile -t vs-code-open-source:next .

$ docker push <branding-organization>/vs-code-open-source:next

8. Create a /.che/che-editor.yaml file in the remote repository that you intend to clone into workspaces. This file must specify the container image of your customized Visual Studio Code - Open Source that is to be pulled for new workspaces.

Example. /che-editor.yaml for the branded Visual Studio Code - Open Source

        memoryRequest: 32Mi
        cpuLimit: 500m
        cpuRequest: 30m

❕ In this example, quay.io/branding-organization/vs-code-open-source:next specifies the container image of a branded Visual Studio Code - Open Source IDE that will be pulled at workspace creation.

Verification

1. Start a new workspace with a clone of the project repository that contains the che-editor.yaml file.

2. Check that the configured UI elements are correctly branded in Visual Studio Code - Open Source in the workspace.
