OpenCost UI

This is the web UI for the OpenCost project. You can learn more about the User Interface in the OpenCost docs.

OpenCost UI Walkthrough OpenCost UI Walkthrough

Installing

See https://www.opencost.io/docs/install for the full instructions.

Using

After following the installation instructions, access the UI by port forwarding:

kubectl port-forward --namespace opencost service/opencost 9090

Running Locally

The UI can be run locally using the npm run serve command.

$ npm install
...
$ npm run serve
> opencost-ui@0.1.0 serve
> npx parcel serve src/index.html

Server running at http://localhost:1234
✨ Built in 1.96s

And can have a custom URL backend prefix.

BASE_URL=http://localhost:9090/test npm run serve

> opencost-ui@0.1.0 serve
> npx parcel serve src/index.html

Server running at http://localhost:1234
✨ Built in 772ms

In addition, similar behavior can be replicated with the docker container:

$ docker run -e BASE_URL_OVERRIDE=test -p 9091:9090 -d opencost-ui:latest
$ curl localhost:9091

Overriding the Base API URL

For some use cases such as the case of OpenCost deployed behind an ingress controller, it is useful to override the BASE_URL variable responsible for requests sent from the UI to the API. This means that instead of sending requests to <domain>/model/allocation/compute/etc, requests can be sent to <domain>/{BASE_URL_OVERRIDE}/allocation/compute/etc. To do this, supply the environment variable BASE_URL_OVERRIDE to the docker image.

$ docker run -p 9091:9090 -e BASE_URL_OVERRIDE=anything -d opencost-ui:latest
