hostd

README

A host for Sia.

Overview

hostd is an advanced Sia host solution created by the Sia Foundation, designed to enhance the experience for storage providers within the Sia network. Tailored for both individual and large-scale storage providers, hostd boasts a user-friendly interface and a robust API, empowering providers to efficiently manage their storage resources and revenue. hostd incorporates an embedded web-UI, simplifying deployment and enabling remote management capabilities, ensuring a smooth user experience across a diverse range of devices.

• A project roadmap is available on GitHub
• Setup guides are available at https://docs.sia.tech

Configuration

hostd can be configured in multiple ways. Some settings, like the wallet key, can be configured via environment variables or stdin. Others, like the RHP ports, can be configured via CLI flags. To simplify more complex configurations, hostd also supports the use of a YAML configuration file for all settings.

Default Ports

hostd uses the following ports:

• 9980 - UI and API
• 9981 - Sia consensus
• 9982 - RHP2
• 9983 - RHP3

Environment Variables

hostd supports the following environment variables:

• HOSTD_API_PASSWORD - The password for the UI and API
• HOSTD_SEED - The recovery phrase for the wallet
• HOSTD_LOG_PATH - changes the path of the log file hostd.log. If unset, the log file will be created in the data directory
• HOSTD_CONFIG_FILE - changes the path of the optional config file. If unset, hostd will check for a config file in the current directory

CLI Flags

-bootstrap
	bootstrap the gateway and consensus modules
-dir string
	directory to store hostd metadata (default ".")
-env
	disable stdin prompts for environment variables (default false)
-http string
	address to serve API on (default ":9980")
-log.level string
	log level (debug, info, warn, error) (default "info")
-log.stdout
	log to stdout (default false)
-name string
	a friendly name for the host, only used for display
-rpc string
	address to listen on for peer connections (default ":9981")
-rhp2 string
	address to listen on for RHP2 connections (default ":9982")
-rhp3.tcp string
	address to listen on for TCP RHP3 connections (default ":9983")
-rhp3.ws string
	address to listen on for WebSocket RHP3 connections (default ":9984")

YAML

All environment variables and CLI flags can be set via a YAML config file. The config file defaults to hostd.yml in the current directory, but can be changed with the HOSTD_CONFIG_FILE environment variable. All fields are optional and default to the same values as the CLI flags.

Building

hostd uses SQLite for its persistence. A gcc toolchain is required to build hostd

go generate ./...
CGO_ENABLED=1 go build -o bin/ -tags='netgo timetzdata' -trimpath -a -ldflags '-s -w'  ./cmd/hostd

Testnet Builds

hostd can be built to run on the Zen testnet by adding the testnet build tag.

The Zen testnet version of hostd changes the environment variables and default ports:

• HOSTD_ZEN_SEED - The recovery phrase for the wallet

• HOSTD_ZEN_API_PASSWORD - The password for the UI and API

• 9880 - UI and API

• 9881 - Sia consensus

• 9882 - RHP2

• 9883 - RHP3

go generate ./...
CGO_ENABLED=1 go build -o bin/ -tags='testnet netgo timetzdata' -trimpath -a -ldflags '-s -w'  ./cmd/hostd

Docker

hostd has a Dockerfile for easy containerization. The image can be pulled from ghcr.io/siafoundation/hostd.

Running container

docker run -d \
  --name hostd \
  -p 127.0.0.1:9980:9980 \
  -p 9981-9983:9981-9983 \
  -v ./data:/data \
  -v ./storage:/storage \
  -e HOSTD_SEED="my wallet seed" \
  -e HOSTD_API_PASSWORD=hostsarecool \
    ghcr.io/siafoundation/hostd:latest

Docker Compose

version: "3.9"
services:
  host:
    image: ghcr.io/siafoundation/hostd:latest
    environment:
      - HOSTD_SEED=my wallet seed
      - HOSTD_API_PASSWORD=hostsarecool
    ports:
      - 127.0.0.1:9980:9980/tcp
      - 9981-9983:9981-9983/tcp
    volumes:
      - /data:/data
      - /storage:/storage
    restart: unless-stopped

Testnet

Suffix any tag with -testnet to use the testnet image.

The Zen testnet version of hostd changes the environment variables and default ports:

• HOSTD_ZEN_SEED - The recovery phrase for the wallet

• HOSTD_ZEN_API_PASSWORD - The password for the UI and API

• HOSTD_ZEN_LOG_PATH - changes the path of the log file hostd.log. If unset, the log file will be created in the data directory

• 9880 - UI and API

• 9881 - Sia consensus

• 9882 - RHP2

• 9883 - RHP3
