How to Deploy SilverBullet

Introduction

SilverBullet is an open-source, local-first, markdown-based knowledge management system. Deploying SilverBullet on Klutch.sh provides scalable, secure infrastructure for your notes and wikis, with support for persistent storage and automated CI/CD.

This guide covers deploying SilverBullet on Klutch.sh using a Dockerfile, configuring persistent storage, and best practices for production deployments.

Prerequisites

  • A Klutch.sh account (sign up here)
  • A GitHub repository for your SilverBullet deployment (or fork of the SilverBullet repo)
  • Basic knowledge of Docker and markdown concepts

1. Prepare your SilverBullet repository

  • Fork or clone the SilverBullet repository, or create a wrapper repo for your customizations.
  • Store large assets (such as configuration files, logs, or database files) outside the Git repo; use persistent volumes or object storage and mount or fetch them at runtime.

Refer to the Klutch.sh Quick Start Guide for repository setup and GitHub integration.

2. Sample non-Docker deployment (Klutch.sh build)

You can deploy SilverBullet from your repo without a Dockerfile using Klutch.sh’s build system:

  1. Push your repo to GitHub. Include a start script (for example: start.sh) that installs dependencies and runs SilverBullet.
  2. In Klutch.sh, create a new project and app, and connect your repository.
  3. Set the start command to the script or SilverBullet’s start command (example: silverbullet serve).
  4. Attach persistent volumes for configuration, logs, or database files (see Volumes Guide).
  5. Set the app port to 3000 (or your configured port).
  6. Click “Create” to build and deploy.

Notes:

  • Configure runtime secrets (database credentials, API keys) as environment variables in Klutch.sh.
  • For advanced use, customize the start script to load assets from mounted volumes or object storage.

A Dockerfile ensures reproducible builds and full control over dependencies. Example:

FROM zefhemel/silverbullet:latest


# Optional: Add custom configuration or plugins
# COPY ./config /silverbullet/config


EXPOSE 3000

For custom assets, mount persistent volumes or fetch from object storage at startup.

4. Persistent storage & volumes

SilverBullet requires persistent storage for configuration, logs, and database files:

  • Create a persistent volume in Klutch.sh and mount it to /silverbullet/config or your chosen path.
  • Configure SilverBullet (or your startup script) to read/write from the mounted path.

Example mount mapping in Klutch.sh app settings:

/silverbullet/config  <- my-silverbullet-storage

If using object storage (S3-compatible), store credentials in environment variables and fetch assets at startup.

5. Environment variables and secrets

  • Store database credentials, API keys, and other secrets in Klutch.sh environment variables (never in the repo).
  • Use the Klutch.sh UI to mark secrets and prevent them from being logged.

6. Scaling, monitoring, and best practices

  • Use health checks and readiness probes if supported by SilverBullet.
  • Monitor CPU, memory, and latency; scale instances as needed.
  • Pin dependency versions and use multi-stage Docker builds for smaller images.
  • Use CI to build and publish images, or let Klutch.sh build from your repo and tag releases.
  • Restrict public access to endpoints; require authentication or place behind an API gateway.

Resources

Deploying SilverBullet on Klutch.sh gives you a reproducible, scalable path to serve markdown-based knowledge management applications. For advanced setups, you can add a startup script to fetch assets from S3, a multi-stage Dockerfile for smaller images, or CI/CD integration to automate builds and deployments.
