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.

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

Current Status

hostd is currently in alpha. It is not yet considered stable and may receive breaking changes at any time. It is recommended to only use hostd on the Zen testnet. Using hostd on the main Sia network is strongly discouraged. By limiting its use to the Zen testnet, you can safely explore its features and contribute to its improvement without risking your assets.

What's Next?

Our current goal is work towards the first stable release of hostd by integrating the UI and enabling migrations for existing siad hosts. A project roadmap is available on GitHub

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 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
