Rancher UI

Perhaps you like managing Cattle.

Usage

Prerequisites:

• Python v3.8 - 3.10
• Git
• Node.js 8.x - 14.x (with NPM)
• Yarn (Note Path Setup)

If you're on a Mac and use Homebrew, you can follow these steps:

  brew install node watchman yarn

Setup:

  git clone 'https://github.com/rancher/ui'
  cd 'ui'
  ./scripts/update-dependencies

Run development server:

  yarn start

Connect to UI at https://localhost:8000/ . The server automatically picks up file changes, restarts itself, and reloads the web browser. This is intended only for development, see below for distributing customizations.

Run development server pointed at another instance of the Rancher API

  RANCHER="https://rancher-server" yarn start

RANCHER can also be hostname[:port] or ip[:port].

Compiling for distribution

Rancher releases include a static copy of the UI passed in during build as a tarball. To generate that, run:

  ./scripts/build-static

Customizing

We highly suggest making customizations as an ember-cli addon rather than forking this repo, making a bunch of changes and then fighting conflicts to keep it up to date with upstream forever. ui-driver-skel is an example addon that adds a custom screen for a docker-machine driver. If there is no way for you to get to what you want to change from an addon, PRs to this repo that add generalized hooks so that you can are accepted.

Project Structure

Rancher UI uses Ember CLI Pods for its project structure. We suggest reading the documentation if you have questions about the layout of the Rancher UI project.

Engines and In-repo Addons

Rancher UI uses Ember Engines to break the deliverable code into smaller chunks and only deliver what the end-user will need. When adding new components to an engine ensure you are only re-exporting the component back out of the engine if it is required and can not be placed in the shared in-repo addon. When adding a new service or dependency that is required by an engine ensure that you pass the dependencies to the engine, more info can be found here

The shared in-repo addon is a central repository of shared components for use with both the main app and any in-repo engine.

Translations

Rancher UI supports localization via translations files. You can swap translations live by utilizing the Language Picker located in the footer. If you would like to add your own translations files follow the directions below.

• Fork the Rancher UI repo
• Copy the en-us.yaml file located in /translations folder and rename using the <language-code>/<country-code>.yaml format (Supported Locales)
• Replace the values on each key with you're new values corresponding to your language
• Ensure you replace the languageName value as this is what will be displayed in the language picker in the UI
• While developing you can use SHFT + L when not focused in an input or text area to toggle the languages between your currently selected language and a special none language to see what key values are missing
• When you've finished you're translations issue a pull request back to the Rancher UI repo to have your translation included

Hosting remotely

If you want to customize the UI, re-packaging all of Rancher to distribute the UI is possible but not terribly convenient. Instead you can change Cattle to load the UI source from a remote web server:

• Build with ./scripts/build-static -l -c 'your-server.com'
• Upload ./dist/static/latest2 so that it's available at https://your-server.com/latest2
  • It must be available over HTTPS.
  • You can rename the "latest2" part with the -v flag
• Change the value of https://your-rancher/v3/settings/ui-index to the same https://your-server.com/latest2 URL
