## Running the Web UI in development mode against a production Nomad cluster | ||
|
||
:warning: **Running the Web UI in development mode is only necessary when debugging | ||
issues. Unless you are debugging an issue, please only use the Web UI contained | ||
in the Nomad binary.** :warning: | ||
|
||
The production Web UI concatenates and minifies JavaScript and CSS. This can make errors | ||
cryptic or useless. In development mode, files are as expected and stack traces are useful. | ||
|
||
Debugging Web UI issues with the Web UI in development mode is done in three steps: | ||
|
||
1. Cloning the Nomad Repo | ||
2. Setting up your environment (or using Vagrant) | ||
3. Serving the Web UI locally while proxying to the production Nomad cluster | ||
|
||
### Cloning the Nomad Repo | ||
|
||
The Web UI is part of the same repo as Nomad itself. Clone the repo | ||
[using Github](https://help.github.com/articles/cloning-a-repository/). | ||
|
||
### Setting up your environment | ||
|
||
The [Web UI README](README.md) includes a list of software prerequisites and instructions | ||
for running the UI locally or with the Vagrant VM. | ||
|
||
### Serving the Web UI locally while proxying to the production Nomad cluster | ||
|
||
Serving the Web UI is done with a single command in the `/ui` directory. | ||
|
||
- **Local:** `ember serve` | ||
- **Vagrant:** `ember serve --watch polling --port 4201` | ||
|
||
However, this will use the [Mirage fixtures](http://www.ember-cli-mirage.com/) as a backend. | ||
To use your own Nomad cluster as a backend, use the proxy option. | ||
|
||
- **Local:** `ember serve --proxy https://demo.nomadproject.io` | ||
- **Vagrant:** `ember serve --watch polling --port 4201 --proxy https://demo.nomadproject.io` | ||
|
||
The Web UI will now be accessible from your host machine. | ||
|
||
- **Local:** [http://localhost:4200](http://localhost:4200) | ||
- **Vagrant:** [http://localhost:4201](http://localhost:4201) |
