The frontend communicates with the web server over +SocketIO, through a custom REST request/response layer. For example, the frontend might make a `GET` request +to `/api/v1/users/{userId}`, but this request is completed via SocketIO, not plain HTTP requests. Note that the API +itself can also be accessed by HTTP. + +The (Swagger/OpenAPI compliant) API spec specifies what requests the frontend can make to the web server. To view this +specification, go to the [Swagger Editor](https://editor.swagger.io/) and paste in +our [opendc-api-spec.yml](../opendc-api-spec.yml). + +The web server receives API requests and processes them in the database. When the frontend requests to run a new +scenario, the web server adds it to the `scenarios` collection in the database and sets its `state` as `QUEUED`. + +The simulator monitors the database for `QUEUED` scenarios, and simulates them as they are submitted. The results of the +simulations are processed and aggregated in memory. Afterwards, the aggregated summary is written to the database, which +the frontend can then again retrieve via the web server. diff --git a/docs/deploy.md b/docs/deploy.md new file mode 100644 index 00000000..b9d65d51 --- /dev/null +++ b/docs/deploy.md @@ -0,0 +1,65 @@ +# Deploying OpenDC + +### Preamble + +The official way to run OpenDC is using Docker. Other options include building and running locally, and building and +running to deploy on a server. + +For all of these options, you have to create a Google API Console project and client ID, which the OpenDC frontend and +web server will use to authenticate users and requests. +Follow [these steps](https://developers.google.com/identity/sign-in/web/sign-in) to make such a project. In the ' +Authorized JavaScript origins' and 'Authorized redirect URI' fields, be sure to add `http://localhost:8080` (frontend) +, `http://localhost:8081` (api) and `https://localhost:3000` (frontend dev). Download the JSON of the OAuth 2.0 client +ID you created from the Credentials tab, and specifically note the `client_id`, which you'll need to build OpenDC. + +### Installing Docker + +OpenDC uses [Docker](https://www.docker.com/) and [Docker Compose](https://docs.docker.com/compose/) to orchestrate the +deployment of the software stack. Please refer to [Docker Desktop](https://www.docker.com/products/docker-desktop) for +instructions on how install Docker on your machine. + +### Running OpenDC + +To build and run the full OpenDC stack locally on Linux or Mac, you first need to clone the project: + +```bash +git clone https://github.com/atlarge-research/opendc.git + +# Enter the directory +cd opendc/ +``` + +In the directory you just entered, you need to set up a set of environment variables. To do this, create a file +called `.env` in the `opendc` folder. In this file, replace `your-google-oauth-client-id` with your `client_id` from the +OAuth client ID you created. For a standard setup, you can leave the other settings as-is. + +```.env +MONGO_INITDB_ROOT_USERNAME=root +MONGO_INITDB_ROOT_PASSWORD=rootpassword +MONGO_INITDB_DATABASE=admin +OPENDC_DB=opendc +OPENDC_DB_USERNAME=opendc +OPENDC_DB_PASSWORD=opendcpassword +OPENDC_FLASK_SECRET="This is a secret flask key, please change" +OPENDC_OAUTH_CLIENT_ID=your-google-oauth-client-id +OPENDC_API_BASE_URL=http://localhost:8081 +``` + +We provide a list of default traces for you to experiment with. If you want to add others, place them in the `traces` +directory and add entries to the database (see also [the database folder](database/mongo-init-opendc-db.sh)) + +If you plan to publicly deploy, please also tweak the other settings. In that case, also check the `docker-compose.yml` +and `docker-compose.pod.yml` for further instructions. + +Now, start the server: + +```bash +# Build the Docker image +docker-compose build + +# Start the containers +docker-compose up +``` + +Wait a few seconds and open `http://localhost:8080` in your browser to use OpenDC. We recommend Google Chrome for the +best development experience. diff --git a/docs/images/logo.png b/docs/images/logo.png Binary files differnew file mode 100644 index 00000000..d743038b --- /dev/null +++ b/docs/images/logo.png diff --git a/docs/images/opendc-component-diagram.png b/docs/images/opendc-component-diagram.png Binary files differnew file mode 100644 index 00000000..312ca72a --- /dev/null +++ b/docs/images/opendc-component-diagram.png diff --git a/docs/images/opendc-frontend-construction.png b/docs/images/opendc-frontend-construction.png Binary files differnew file mode 100644 index 00000000..223e8d48 --- /dev/null +++ b/docs/images/opendc-frontend-construction.png diff --git a/docs/images/opendc-frontend-simulation-zoom.png b/docs/images/opendc-frontend-simulation-zoom.png Binary files differnew file mode 100644 index 00000000..d7744926 --- /dev/null +++ b/docs/images/opendc-frontend-simulation-zoom.png diff --git a/docs/images/opendc-frontend-simulation.png b/docs/images/opendc-frontend-simulation.png Binary files differnew file mode 100644 index 00000000..bbf4cbd6 --- /dev/null +++ b/docs/images/opendc-frontend-simulation.png |
