⚠️ This is a read only repository, all development has been moved to SkynetLabs/skynet-webportal.

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/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")

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.

Make sure to create your owndocker/kratos/config/kratos.yml by copying the kratos.yml.sample in the same directory. Also make sure to never add that file to source control because it will most probably contain your email password in plain text!

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:.

CockroachDB Setup

Kratos uses CockroachDB to store its data. For that data to be shared across all nodes that comprise your portal cluster setup, we need to set up a CockroachDB cluster, complete with secure communication.

Generate the certificates for secure communication

For a detailed walk-through, please check this guide out.

Steps:

  1. Start a local cockroach docker instance: docker run -d -v "<local dir>:/cockroach/cockroach-secure" --name=crdb cockroachdb/cockroach start --insecure
  2. Get a shall into that instance: docker exec -it crdb /bin/bash
  3. Go to the directory we which we mapped to a local dir: cd /cockroach/cockroach-secure
  4. Create the subdirectories in which to create certificates and keys: mkdir certs my-safe-directory
  5. Create the CA (Certificate Authority) certificate and key pair: cockroach cert create-ca --certs-dir=certs --ca-key=my-safe-directory/ca.key
  6. Create a client certificate and key pair for the root user: cockroach cert create-client root --certs-dir=certs --ca-key=my-safe-directory/ca.key
  7. Create the certificate and key pair for your nodes: cockroach cert create-node cockroach mynode.siasky.net --certs-dir=certs --ca-key=my-safe-directory/ca.key. Don't forget the cockroach node name - it's needed by our docker-compose setup. If you want to create certificates for more nodes, just delete the node.* files (after you've finished the next steps for this node!) and re-run the above command with the new node name.
  8. Put the contents of the certs folder under docker/cockroach/certs/* under your portal's root dir and store the content of my-safe-directory somewhere safe.
  9. Put another copy of those certificates under docker/kratos/cr_certs and change permissions of the *.key files, so they can be read by anyone (644).

Configure your CockroachDB node

There is some configuration that needs to be added to your .envfile, namely:

  1. CR_NODE - the name of your node
  2. CR_IP - the public IP of your node
  3. CR_CLUSTER_NODES - a list of IPs and ports which make up your cluster, e.g. 95.216.13.185:26257,147.135.37.21:26257,144.76.136.122:26257. This will be the list of nodes that will make up your cluster, so make sure those are accurate.
