Skynet Portal

Web application

Use yarn workspace webapp start to start the development server.

Use yarn workspace webapp 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 workspace webapp start
• production example GATSBY_API_URL=https://siasky.net yarn workspace webapp 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 run an initialisation docker run with extra environment variables that will initialise the admin user with a password (example below).
• Manually add a mgkey file under ./docker/data/mongo with the respective secret (see Mongo's keyfile access control for details).
• 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 master node and run rs.add() in order to add the new node to the cluster.

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

Cluster initialisation mongo command:

rs.initiate(
  {
    _id : "skynet",
    members: [
      { _id : 0, host : "mongo0.example.com:27017" },
      { _id : 1, host : "mongo1.example.com:27017" },
    ]
  }
)

Kratos & Oathkeeper Setup

Kratos is our user management system of choice and Oathkeeper is the identity and access proxy.

Most of the needed config is already under docker/kratos. The only two things that need to be changed are the config for Kratos that might contain you email server password, and the JWKS Oathkeeper uses to sign its JWT tokens.

To override the default kratos.yml you can create .kratos.yml in the root directory of the project, alongside the .env file.

To override the JWKS you will need to directly edit docker/kratos/oathkeeper/id_token.jwks.json and replace it with your generated key set. If you don't know how to generate a key set you can use this code:

package main

import (
	"encoding/json"
	"log"
	"os"

	"github.com/ory/hydra/jwk"
)

func main() {
	gen := jwk.RS256Generator{
		KeyLength: 2048,
	}
	jwks, err := gen.Generate("", "sig")
	if err != nil {
		log.Fatal(err)
	}
	jsonbuf, err := json.MarshalIndent(jwks, "", "  ")
	if err != nil {
		log.Fatal("failed to generate JSON: %s", err)
	}
	os.Stdout.Write(jsonbuf)
}

While you can directly put the output of this programme into the file mentioned above, you can also remove the public key from the set and change the kid of the private key to not include the prefix private:.
