## Consul Web UI
|
|
|
|
This directory contains the Consul Web UI. Consul contains a built-in
|
|
HTTP server that serves this directory, but any common HTTP server
|
|
is capable of serving it.
|
|
|
|
It uses JavaScript and [Ember](http://emberjs.com) to communicate with
|
|
the [Consul API](https://www.consul.io/api/index.html). The basic
|
|
features it provides are:
|
|
|
|
- Service view. A list of your registered services, their
|
|
health and the nodes they run on.
|
|
- Node view. A list of your registered nodes, the services running
|
|
on each and the health of the node.
|
|
- Key/value view and update
|
|
|
|
It's aware of multiple datacenters, so you can get a quick global
|
|
overview before drilling into specific data-centers for detailed
|
|
views.
|
|
|
|
The UI uses some internal undocumented HTTP APIs to optimize
|
|
performance and usability.
|
|
|
|
### Development
|
|
|
|
Improvements and bug fixes are welcome and encouraged for the Web UI.
|
|
|
|
You'll need sass to compile CSS stylesheets. Install that with
|
|
bundler:
|
|
|
|
cd ui/
|
|
bundle
|
|
|
|
Reloading compilation for development:
|
|
|
|
make watch
|
|
|
|
Consul ships with an HTTP server for the API and UI. By default, when
|
|
you run the agent, it is off. However, if you pass a `-ui-dir` flag
|
|
with a path to this directory, you'll be able to access the UI via the
|
|
Consul HTTP server address, which defaults to `localhost:8500/ui`.
|
|
|
|
An example of this command, from inside the `ui/` directory, would be:
|
|
|
|
consul agent -bootstrap -server -data-dir /tmp/ -ui-dir .
|
|
|
|
Basic tests can be run by adding the `?test` query parameter to the
|
|
application.
|
|
|
|
When developing Consul, it's recommended that you use the included
|
|
development configuration.
|
|
|
|
consul agent -config-file=development_config.json
|
|
|
|
### Releasing
|
|
|
|
`make dist`
|
|
|
|
The `../pkg/web_ui` folder will contain the files you should use for deployment.
|

### Compiling the UI into the Go binary
|
|
|
|
The UI is compiled and shipped with the Consul go binary. The generated bindata
|
|
file lives in the `command/agent/bindata_assetfs.go` file and is checked into
|
|
source control. This is useful so that not every Consul developer needs to set
|
|
up bundler etc. To re-generate the file, first follow the compilation steps
|
|
above to build the UI assets into the `pkg/web_ui` folder. With that done, from the
|
|
root of the Consul repo, run:
|
|
|
|
```
|
|
$ make static-assets
|
|
```
|
|
|
|
The file will now be refreshed with the current UI data. You can now rebuild the
|
|
Consul binary normally with `make bin` or `make dev`, and see the updated UI
|
|
after re-launching Consul.
