# Skynet Portal

## Web application

Change current directory with `cd packages/website`.

Use `yarn start` to start the development server.

Use `yarn build` to compile the application to `/public` directory.

You can use the below build parameters to customize your web application.

- development example `GATSBY_API_URL=https://siasky.dev yarn start`
- production example `GATSBY_API_URL=https://siasky.net yarn build`

List of available parameters:

- `GATSBY_API_URL`: override api url (defaults to location origin)

### MongoDB Setup

Mongo needs a couple of extra steps in order to start a secure cluster.

- Open port 27017 on all nodes that will take part in the cluster. Ideally, you would only open the port for the other
  nodes in the cluster.
- Manually add a `mgkey` file under `./docker/data/mongo` with the respective secret (
  see [Mongo's keyfile access control](https://docs.mongodb.com/manual/tutorial/enforce-keyfile-access-control-in-existing-replica-set/)
  for details).
- Manually run an initialisation `docker run` with extra environment variables that will initialise the admin user with
  a password (example below).
- During the initialisation run mentioned above, we need to make two extra steps within the container:
  - Change the ownership of `mgkey` to `mongodb:mongodb`
  - Change its permissions to 400
- After these steps are done we can open a mongo shell on the primary node and run `rs.add()` in order to add the new
  node to the cluster. If you don't know which node is primary, log onto any server and jump into the Mongo's container
  (`docker exec -it mongo mongo -u admin -p`) and then get the status of the replica set (`rs.status()`).

Example initialisation docker run command:

```
docker run \
	--rm \
	--name mg \
	-p 27017:27017 \
	-e MONGO_INITDB_ROOT_USERNAME=<admin username> \
	-e MONGO_INITDB_ROOT_PASSWORD=<admin password> \
	-v /home/user/skynet-webportal/docker/data/mongo/db:/data/db \
	-v /home/user/skynet-webportal/docker/data/mongo/mgkey:/data/mgkey \
	mongo --keyFile=/data/mgkey --replSet=skynet
```

Regular docker run command:

```
docker run \
	--rm \
	--name mg \
	-p 27017:27017 \
	-v /home/user/skynet-webportal/docker/data/mongo/db:/data/db \
	-v /home/user/skynet-webportal/docker/data/mongo/mgkey:/data/mgkey \
	mongo --keyFile=/data/mgkey --replSet=skynet
```

Cluster initialisation mongo command:

```
rs.initiate(
  {
    _id : "skynet",
    members: [
      { _id : 0, host : "mongo:27017" }
    ]
  }
)
```

Add more nodes when they are ready:

```
rs.add("second.node.net:27017")
```

### Testing Your Code

Before pushing your code, you should verify that it will pass our online test suite.

**Cypress Tests**
Verify the Cypress test suite by doing the following:

1. In one terminal screen run `GATSBY_API_URL=https://siasky.net website serve`
1. In a second terminal screen run `yarn cypress run`

## Setting up complete skynet server
