SilverBullet deployment examples

Below you'll find user examples on how to deploy SilverBullet using different alternatives.

NOTE: paths, usernames and passwords are just examples and should be updated to your own personal environment

NOTE: These deployments are based in a Linux environment though they may perfectly work in Windows and/or MacOS with minimal changes

How to Deploy Silverbullet with Docker

This example will work both if you use docker-compose.yml files or a management tool like portainer.

We will configure SilverBullet with caddy as reverse proxy, redis to store and share certificates and authelia for authentication.

Docker compose file

IMPORTANT: Some volumes configured below are bind mounts which need to be configured providing a physical folder from your machine. Don't forget to create them before turning up the containers.

NOTE: We are configuring SilverBullet with basic auth assuming there may be more users and applications in the server. Feel free to remove it if that is not the case, to avoid a double login requirement.

  silverbullet:
    container_name: silverbullet
    image: zefhemel/silverbullet
    volumes:
      - /media/silverbullet/space:/space
    ports:
      - 3000:3000
    restart: unless-stopped
    environment:
      - PUID=1000
      - PGID=1000
      - SB_USER=${USERNAME}:${PASSWORD} #feel free to remove this if not needed

  redis:
    container_name: redis
    image: "redis:alpine"
    command: redis-server --save "" --appendonly "no"
    restart: always
    networks:
      - searxng
    tmpfs:
      - /var/lib/redis
    cap_drop:
      - ALL
    cap_add:
      - SETGID
      - SETUID
      - DAC_OVERRIDE

  caddy:
    container_name: caddy
    image: caddy:latest
    network_mode: host
    restart: always
    volumes:
      - /media/caddy/config/Caddyfile:/etc/caddy/Caddyfile:ro
      - caddy-data:/data:rw
      - caddy-config:/config:rw
    cap_drop:
      - ALL
    cap_add:
      - NET_BIND_SERVICE
      - DAC_OVERRIDE

  authelia:
    image: authelia/authelia
    container_name: authelia
    volumes:
      - /media/authelia/config:/config 
    ports:
      - 9091:9091
    environment:
      - PUID=1000
      - PGID=1000

volumes:
  caddy-data:
  caddy-config:

In case you use SilverBullet basic auth feature, you'll need to provide the following env file

USERNAME=User
PASSWORD=REDACTED

authelia

authelia requires two configuration files: users_databases.yml and configuration.yml Please check the official documentation for all the possibilities. Below you can find a very simple example that will work for our use case.

User configuration

Run the following command in /media/authelia/config/ folder in order to generate the argon2id password

docker run -v ./configuration.yml:/configuration.yml -it authelia/authelia:latest authelia crypto hash generate --config /configuration.yml

Then copy the password in the /media/authelia/config/users_database.yml file

  • users_database.yml
users:
  User:
    disabled: false
    displayname: "User"
    password: "$argon2id$v=19$m=65536,t=3,p=4$blahblahblah"
    email: User@domain.com
    groups:
      - admins

configuration.yml

Simplified version, with a lot of boilerplate removed. Official template can be found here

/media/authelia/config/configuration.yml

##
## Access Control Configuration
##
## Access control is a list of rules defining the authorizations applied for one resource to users or group of users.
##
access_control:
  ## Default policy can either be 'bypass', 'one_factor', 'two_factor' or 'deny'. It is the policy applied to any
  ## resource if there is no policy to be applied to the user.
  default_policy: deny

  rules:
    ## bypass rule
    - domain: 'auth.domain.com' #This should be your authentication URL
      policy: bypass
    - domain: 'silverbullet.domain.com'
      resources:
        - '/.client/manifest.json$'
        - '/.client/[a-zA-Z0-9_-]+.png$'
        - '/service_worker.js$'
      policy: bypass
    - domain: 'silverbullet.domain.com'
      subject:
        - 'group:admins'
      policy: one_factor


##
## Session Provider Configuration
##
## The session cookies identify the user once logged in.
## The available providers are: `memory`, `redis`. Memory is the provider unless redis is defined.
session:
  ## The name of the session cookie.
  name: authelia_session
  ## The domain to protect.
  ## Note: the authenticator must also be in that domain.
  ## If empty, the cookie is restricted to the subdomain of the issuer.
  domain: domain.com
  ## Sets the Cookie SameSite value. Possible options are none, lax, or strict.
  ## Please read https://www.authelia.com/c/session#same_site
  same_site: lax
  ## The secret to encrypt the session data. This is only used with Redis / Redis Sentinel.
  ## Secret can also be set using a secret: https://www.authelia.com/c/secrets
  secret: 3sdffgsdgs33452j2jhgjs9gdfg
  ## The value for expiration, inactivity, and remember_me_duration are in seconds or the duration notation format.
  ## See: https://www.authelia.com/c/common#duration-notation-format
  ## All three of these values affect the cookie/session validity period. Longer periods are considered less secure
  ## because a stolen cookie will last longer giving attackers more time to spy or attack.
  ## The time before the cookie expires and the session is destroyed if remember me IS NOT selected.
  expiration: 1h
  ## The inactivity time before the session is reset. If expiration is set to 1h, and this is set to 5m, if the user
  ## does not select the remember me option their session will get destroyed after 1h, or after 5m since the last time
  ## Authelia detected user activity.
  inactivity: 5m
  ## The time before the cookie expires and the session is destroyed if remember me IS selected.
  ## Value of -1 disables remember me.
  remember_me_duration: 1M

##
## Regulation Configuration
##
## This mechanism prevents attackers from brute forcing the first factor. It bans the user if too many attempts are made
## in a short period of time.
regulation:
  ## The number of failed login attempts before user is banned. Set it to 0 to disable regulation.
  max_retries: 3
  ## The time range during which the user can attempt login before being banned. The user is banned if the
  ## authentication failed 'max_retries' times in a 'find_time' seconds window. Find Time accepts duration notation.
  ## See: https://www.authelia.com/c/common#duration-notation-format
  find_time: 2m
  ## The length of time before a banned user can login again. Ban Time accepts duration notation.
  ## See: https://www.authelia.com/c/common#duration-notation-format
  ban_time: 5m

##
## Storage Provider Configuration
##
## The available providers are: `local`, `mysql`, `postgres`. You must use one and only one of these providers.
storage:
  local:
    path: /config/db.sqlite3 #this is your databse. You could use a mysql database if you wanted, but we're going to use this one.
  encryption_key: 345f2f5v6c54vg2ewesd

##
## Notification Provider
##
## Notifications are sent to users when they require a password reset, a Webauthn registration or a TOTP registration.
## The available providers are: filesystem, smtp. You must use only one of these providers.
notifier:
  ## You can disable the notifier startup check by setting this to true.
  disable_startup_check: true #true/false
  smtp:
    username: user@gmail.com #your email address
    password: apppassword #your email password
    host: smtp.gmail.com #email smtp server
    port: 587 #email smtp port
    sender: user@gmail.com
    subject: "[Authelia] {title}" #email subject

caddy (reverse proxy)

Example of /media/caddy/config/Caddyfile

{
  admin off
}


## It is important to read the following document before enabling this section:
##     https://www.authelia.com/integration/proxies/caddy/#forwarded-header-trust#trusted-proxies
(trusted_proxy_list) {
       ## Uncomment & adjust the following line to configure specific ranges which should be considered as trustworthy.
      trusted_proxies 192.168.0.0/16
}


# Authelia Portal.
auth.domain.com {
        reverse_proxy localhost:9091 {
                ## This import needs to be included if you're relying on a trusted proxies configuration.
                import trusted_proxy_list
        }
}

silverbullet.domain.com {
        forward_auth localhost:9091 {
                uri /api/verify?rd=https://auth.domain.com/
                copy_headers Remote-User Remote-Groups Remote-Name Remote-Email

                ## This import needs to be included if you're relying on a trusted proxies configuration.
                import trusted_proxy_list
        }
        reverse_proxy localhost:3000 {
                ## This import needs to be included if you're relying on a trusted proxies configuration.
                import trusted_proxy_list
        }
}

Syncing SilverBullet with Git

  • Once the server is up and running we can install git Plug (if not installed by default)
- github:silverbulletmd/silverbullet-git/git.plug.js
  • we need to create a git repository to sync automatically
    • Example: https://github.com/user/silverbullet
  • Create a github token to run git pull and git push within silverbullet
    • Example token: ghp_sdfasdfsdfZFwJGHFGDSF554a
  • Now we initialize the repo and create a first push
cd /media/silverbullet/space
git init
git add index.md
git commit -m "first commit"
git branch -M main
git remote add origin https://ghp_sdfasdfsdfZFwJGHFGDSF554a@github.com/user/silverbullet.git
git push -u origin main
git branch --set-upstream-to=origin/main main
  • Once we confirm github sync works from the terminal, we need to add our github identity inside the container
  • Connect through portainer or the command line to the silverbullet console
docker exec -it silverbullet /bin/sh
cd /space
git config user.email "user@gmail.com"
git config --global user.name "user"

And we are DONE! We can now use SilverBullet and run Git Sync everytime we would like to commit and sync our changes to github.

How to Deploy Silverbullet with Deno

  • We will use cargo to install deno for this use case
cargo install deno --locked

NOTE: Please refer to the official documentation to set up properly your environment.

  • Now we proceed to install SilverBullet
deno install -f --name silverbullet -A https://get.silverbullet.md

How to run SilverBullet at boot with systemd

#!/bin/bash
## Script to start SilverBullet through Deno

/home/user/.cargo/bin/deno run --allow-all --no-config https://get.silverbullet.md/ /home/user/silverbullet > /home/user/sb.log 2> /home/user/sb.err
  • Create /etc/systemd/system/silverbullet.service file:
[Unit]
Description=SilverBullet

[Service]
User=user
Type=simple
ExecStart=/usr/local/bin/silverbullet.sh

[Install]
WantedBy=multi-user.target
  • Enable and start the service
sudo systemctl enable silverbullet.service
sudo systemctl start silverbullet.service
  • Once SilverBullet is up and running, you'll have access to the logs and errors through the sb.log and sb.err files located in /home/user
