Flyte Console

Web UI for the Flyte platform

Contribution Guide

📦 Install Dependencies

Running flyteconsole locally requires NodeJS and yarn. Once these are installed, you can run application locally. For help with installing dependencies look into Installation section.

🚀 Quick Start

1. Follow Start a Local flyte backend, like:

   docker run --rm --privileged -p 30080:30080 -p 30081:30081 -p 30082:30082 -p 30084:30084 cr.flyte.org/flyteorg/flyte-sandbox

2. Now, export the following env variables:

   export ADMIN_API_URL=http://localhost:30080

   You can persist these environment variables either in the current shell or in a .env file at the root of the repository. A .env file will persist the settings across multiple terminal sessions.

3. Start the server (uses localhost:3000)

   yarn start

4. Explore your local copy at http://localhost:3000

Note: Python errors with OSX

Recently OSX (12.3) removed python 2.7 from default installation and this can cause build errors for some users depending on it's setup. In this repository you can experience env: python: No such file or directory error from gyp (node-gyp). The easiest way to fix it:

• Install the XCode Command Line Tools standalone by running xcode-select --install in the terminal

OR

   brew install python    # install python with brew
   which python           # check if python path is properly defined
   # if path not defined
   where python3
   # Take the version and location from above and run this command (replacing `/usr/bin/python3` with the location of your python instalation). This will symlink python to python3
   ln -s /usr/bin/python3 /usr/local/bin/python

Environment Variables

• ADMIN_API_URL (default: window.location.origin)

  The Flyte Console displays information fetched from the FlyteAdmin API. This environment variable specifies the host prefix used in constructing API requests.

  Note: this is only the host portion of the API endpoint, consisting of the protocol, domain, and port (if not using the standard 80/443).

  This value will be combined with a suffix (such as /api/v1) to construct the final URL used in an API request.

  Default Behavior

  In most cases, flyteconsole will be hosted in the same cluster as the Admin API, meaning that the domain used to access the console is the same value used to access the API. For this reason, if no value is set for ADMIN_API_URL, the default behavior is to use the value of window.location.origin.

• BASE_URL (default: undefined)

  This setting allows running the console at a prefix on the target host. This is necessary when hosting the API and console on the same domain (with prefixes of /api/v1 and /console for example). For local development, this is usually not needed, so the default behavior is to run without a prefix.

• FLYTE_NAVIGATION (default: undefined) UI related. Allows you to change colors of the navigation bar and add links to other internal pages or external sites. More info

Running from docker image as localhost

To run flyteconsole directly from your docker image as localhost you must set a few environment variables in your run command to setup the appliation.

BASE_URL="/console" (required)

CONFIG_DIR="/etc/flyte/config" (required)

This example assumes building from v1.0.0 on port 8080

docker run -p 8080:8080 -e BASE_URL="/console" -e CONFIG_DIR="/etc/flyte/config" ghcr.io/flyteorg/flyteconsole:v1.0.0

Run the server

To start the local development server run:

yarn install    # to install node_modules
yarn start      # to start application

This will spin up a Webpack development server, compile all of the code into bundles, and start the NodeJS server on the default port (3000). All requests to the NodeJS server will be stalled until the bundles have finished. The application will be accessible at http://localhost:3000 (if using the default port).

🎱 Using items in your own application

• Authorize your app to call flyte admin api. More info

🛠 Development

For continious development we are using:

• Protobuf and Debug Output. Protobuf is a binary response/request format, which makes Network Tab hardly useful. To get more info on requests - use our Debug Output

• Storybook - used for component stories and base UI testing.

• Feature flags - allows to enable/disable specific code paths. Used to simplify continious development.

• Google Analytics - adds tracking code to the app or website. To disable use ENABLE_GA=false

More info on each section could be found at CONTRIBUTING.md

• Set ADMIN_API_URL and ADMIN_API_USE_SSL

  export ADMIN_API_URL=https://different.admin.service.com
  export ADMIN_API_USE_SSL="https"
  export LOCAL_DEV_HOST=localhost.different.admin.service.com

  Hint: Add these to your local profile (eg, ./profile) to prevent having to do this step each time

• Generate SSL certificate

  Run the following command from your flyteconsole directory

  make generate_ssl

• Add new record to hosts file

  sudo vim /etc/hosts

  Add the following record

  127.0.0.1 localhost.different.admin.service.com

• Install Chrome plugin: Moesif Origin & CORS Changer

  NOTE:

  1. Activate plugin (toggle to "on")
  2. Open 'Advanced Settings':

  • set Access-Control-Allow-Credentials: true
  • set Domain List: your.localhost.com

• Start flyteconsole

  yarn start

  Your new localhost is localhost.different.admin.service.com

  Hint: Ensure you don't have ADMIN_API_URL set (eg, in your /.profile.)
