Docker is a convenient and secure way to install server applications either locally or on a server you control. If you don’t have docker already running on your machine and are macOS user, consider giving OrbStack a try — it’s a super nice docker experience.
Conveniently, SilverBullet is published as a docker image on GHCR. The image comes in two flavors:
There is no 32-bit version of Deno, and therefore we cannot offer a 32-bit version of SilverBullet either. Most people run 64-bit OSes these days, an exception may be Raspberry Pis. Recent (RPI 3 and later) can run 64-bit Linux as well, you may have to re-image, though.
A few key things to know about the SilverBullet container image:
* The container binds to port 3000, so be sure to port-map that, e.g. via -p 3000:3000 (note: the first 3000 is the external port)
* The container uses whatever is volume-mapped to /space as the space root folder. You can connect a docker volume, or a host folder to this, e.g. -v /home/myuser/space:/space
* SilverBullet will detect the UNIX owner (UID and GID) of the folder mapped into /space and run the server process with the same UID and GID so that permissions will just magically work. If you’d like to override this UID, set the PUID and PGID environment variables (see Install/Configuration for details).
* The Docker image is based on Alpine. If you'd like to install additional packages into it, see #Installing additional packages below.
note Note The same docker images are currently both available from GHCR and Docker Hub, use whichever you prefer.
For your first run, you can run the following:
# Create a local folder "space" to keep files in
mkdir -p space
# Run the SilverBullet docker container in the foreground
sudo docker run -it -p 3000:3000 -v ./space:/space ghcr.io/silverbulletmd/silverbullet
This will run SilverBullet in the foreground, interactively, so you can see the logs and instructions.
If this all works fine, just kill the thing with Ctrl-c (don’t worry, it’s ok).
Now you probably want to run the container in daemon (background) mode, give it a name, and automatically have it restart after you e.g. reboot your machine:
docker run -d --restart unless-stopped --name silverbullet -p 3000:3000 -v ./space:/space ghcr.io/silverbulletmd/silverbullet
There you go!
Note that to get offline mode to work you need to serve SilverBullet with HTTPS, via for example a reverse proxy.
If you would like to install additional packages into your docker container (e.g. to call via API/shell), you can do so by creating a CONTAINER_BOOT page in your space. Whatever you put in this page, will be run as a bash script upon container boot (hence its name).
In practice, you’ll likely want to put apk add commands install the (Alpine) packages you would like to install.
There are two release channels:
* Stable: for this use the :latest images
* Edge: for this use the :v2 tag (e.g. ghcr.io/silverbulletmd/silverbullet:v2) — these images are always in sync with the main development branch.
To check the version you’re running, use the ${widgets.commandButton("Client: Version")} command.
You can upgrade SilverBullet as follows:
# Pull the latest version of the image
docker pull ghcr.io/silverbulletmd/silverbullet
# Kill the running container
docker kill silverbullet
# Remove the old container
docker rm silverbullet
# Start a fresh one (same command as before)
docker run -d --restart unless-stopped --name silverbullet -p 3000:3000 -v $PWD/space:/space ghcr.io/silverbulletmd/silverbullet
Since this is somewhat burdensome, it is recommended you use a tool like watchtower to automatically update your docker images and restart them. However, if we go there — we may as well use a tool like docker compose to manage your containers, no?
To upgrade your client, be sure to refresh your page twice somewhat slowly.
Docker compose is a simple tool to manage running of multiple containers on a server you control. It’s like Kubernetes, but you know, not insanely complex.
Here is a simple compose.yml that runs SilverBullet as well as watchtower, which will check for new SilverBullet upgrades daily (the default) and upgrade automatically.
Instructions:
* Please replace the password defined in SB_USER with something sensible such as admin:b3stp4ssword3vah
* This volume uses the ./space directory (which you should create) in the same directory as the compose.yml file as the place where SB will keep its space.
* Check out Install/Configuration for more interesting environment variables you can set.
services:
silverbullet:
image: ghcr.io/silverbulletmd/silverbullet
restart: unless-stopped
environment:
- SB_USER=admin:admin
volumes:
- ./space:/space
ports:
- 3000:3000
# To enable auto upgrades, run watchtower
watchtower:
image: containrrr/watchtower
volumes:
- /var/run/docker.sock:/var/run/docker.sock
Boot this up via:
docker-compose up -d
And watch for logs with:
docker-compose logs -f
