#### `siyuan-note`
[](https://repology.org/project/siyuan-note/versions)
### Docker Hosting
<details>
<summary>Docker Deployment</summary>
#### Overview
The easiest way to serve SiYuan on a server is to deploy it through Docker.
- Image name `b3log/siyuan`
- [Image URL](https://hub.docker.com/r/b3log/siyuan)
#### File structure
The overall program is located under `/opt/siyuan/`, which is basically the structure under the resources folder of the Electron installation package:
- appearance: icon, theme, languages
- guide: user guide document
- stage: interface and static resources
- kernel: kernel program
#### Entrypoint
The entry point is set when building the Docker image: `ENTRYPOINT ["/opt/siyuan/entrypoint.sh"]`. This script allows changing the `PUID` and `PGID` of the user that will run inside the container. This is especially relevant to solve permission issues when mounting directories from the host. The `PUID` (User ID) and `PGID` (Group ID) can be passed as environment variables, making it easier to ensure correct permissions when accessing host-mounted directories.
Use the following parameters when running the container with `docker run b3log/siyuan`:
> **Note:** Since v3.7.0, the `serve` subcommand must be passed explicitly (e.g. `docker run b3log/siyuan serve --workspace=...`). Run `docker run --rm b3log/siyuan serve --help` to see all serving options.
- `--workspace`: Specifies the workspace folder path, mounted to the container via `-v` on the host
- `--accessAuthCode`: Specifies the lock screen password
More parameters can be found using `--help`. Here’s an example of a startup command with the new environment variables:
```bash
docker run -d \
-v workspace_dir_host:workspace_dir_container \
-p 6806:6806 \
-e PUID=1001 -e PGID=1002 \
b3log/siyuan \
serve \
--workspace=workspace_dir_container \
--accessAuthCode=xxx
```
- `PUID`: Custom user ID (optional, defaults to `1000` if not provided)
- `PGID`: Custom group ID (optional, defaults to `1000` if not provided)
- `workspace_dir_host`: The workspace folder path on the host
- `workspace_dir_container`: The path of the workspace folder in the container, as specified in `--workspace`
- Alternatively, it's possible to set the path via the `SIYUAN_WORKSPACE_PATH` env variable. The commandline will always have the priority, if both are set
- `accessAuthCode`: Lock screen password (please **be sure to modify**, otherwise anyone can access your data)
- Alternatively, it's possible to set the lock screen password via the `SIYUAN_ACCESS_AUTH_CODE` env variable. The commandline will always have the priority, if both are set
- To disable the lock screen password set the env variable `SIYUAN_ACCESS_AUTH_CODE_BYPASS=true`
- OIDC can replace the lock screen password as the required Docker access authentication. Set `SIYUAN_OIDC_ENABLED=true`, `SIYUAN_OIDC_PROVIDER` (`custom`, `google`, `microsoft`, or `github`), `SIYUAN_OIDC_CLIENT_ID`, and the provider-specific values below. GitHub uses its OAuth 2.0 user API adapter; the other providers use OpenID Connect discovery and ID Token validation. An invalid enabled configuration stops Docker startup when no lock screen password is available
- `SIYUAN_OIDC_ISSUER_URL`: Issuer URL required by the `custom` and `microsoft` providers; Microsoft must use a tenant-specific issuer such as `https://login.microsoftonline.com/<tenant-id>/v2.0`
- `SIYUAN_OIDC_CLIENT_SECRET`: Optional client secret for OpenID Connect providers; required by the GitHub OAuth adapter. Every authorization-code flow also uses PKCE
- `SIYUAN_OIDC_SCOPES`: Comma- or space-separated scopes; `openid` is always included
- `SIYUAN_OIDC_REDIRECT_URL`: Public HTTPS callback URL ending in `/api/system/oidc/callback`, required for remote browser access
- `SIYUAN_OIDC_ALLOW_ALL`: Explicitly grant SiYuan administrator access to every identity authenticated by the provider
- `SIYUAN_OIDC_CLAIM_RULES`: JSON array of claim rules used when allow-all is disabled, for example `[{"claim":"email","operator":"equals","values":["[email protected]"]},{"claim":"email_verified","operator":"equals","values":["true"]}]`; values within a rule use OR, while rules use AND
- Native mobile apps use the fixed callback URI `siyuan:/oidc-callback`; register it exactly as written. Mobile configuration verification uses this callback before saving. Custom providers, Microsoft, and GitHub can be used only when their application registration accepts this callback URI. Google does not accept this private-use URI for its Android client type, so Google login is limited to browser and desktop flows
- `SIYUAN_LANG`: Interface language (optional, defaults to `en` if unset in Docker). Accepts BCP 47 tags like `zh-CN`/`zh-TW`/`en`/`ja`/`pt-BR`; legacy underscore values like `zh_CN`/`en_US` are also accepted for backward compatibility. Omit it if you want the language chosen in **Settings** to persist across restarts; if set, it is applied on every startup and overrides the saved setting
- Alternatively, use the `--lang` command-line parameter. If both are set, the command-line takes priority
To simplify things, it is recommended to configure the workspace folder path to be consistent on the host and container, such as having both `workspace_dir_host` and `workspace_dir_container` configured as `/siyuan/workspace`. The corresponding startup command would be:
```bash
docker run -d \
-v /siyuan/workspace:/siyuan/workspace \
-p 6806:6806 \
-e PUID=1001 -e PGID=1002 \
b3log/siyuan \
serve \
--workspace=/siyuan/workspace/ \
--accessAuthCode=xxx
```
#### Docker Compose
For users running SiYuan with Docker Compose, the environment variables `PUID` and `PGID` can be passed to customize the user and group IDs. Here's an example of a Docker Compose configuration:
```yaml
version: "3.9"
services:
main:
image: b3log/siyuan
command: ['serve', '--workspace=/siyuan/workspace/', '--accessAuthCode=${AuthCode}']
ports:
- 6806:6806
volumes:
- /siyuan/workspace:/siyuan/workspace
restart: unless-stopped
environment:
- TZ=${YOUR_TIME_ZONE} # A list of time zone identifiers can be found at https://en.wikipedia.org/wiki/List_of_tz_database_time_zones
- PUID=${YOUR_USER_PUID} # Customize user ID
- PGID=${YOUR_USER_PGID} # Customize group ID
```
In this setup:
- `PUID` and `PGID` are set dynamically and passed to the container
- If these variables are not provided, the default `1000` will be used
By specifying `PUID` and `PGID` in the environment, you avoid the need to explicitly set the `user` directive (`user: '1000:1000'`) in the compose file. The container will dynamically adjust the user and group based on these environment variables at startup.
#### User Permissions
In the image, the `entrypoint.sh` script ensures the creation of the `siyuan` user and group with the specified `PUID` and `PGID`. Therefore, when the host creates a workspace folder, pay attention to setting the user and group ownership of the folder to match the `PUID` and `PGID` you plan to use. For example:
```bash
chown -R 1001:1002 /siyuan/workspace
```
If you use custom `PUID` and `PGID` values, the entrypoint script will ensure that the correct user and group are created inside the container, and ownership of mounted volumes will be adjusted accordingly. There’s no need to manually pass `-u` in `docker run` or `docker-compose` as the environment variables will handle the customization.
#### Hidden port
Use an NGINX reverse proxy to hide port 6806. Please note:
- Configure the WebSocket reverse proxy for `/ws`
#### Note
- Be sure to confirm the correctness of the mounted volume, otherwise the data will be lost after the container is deleted
- Do not use URL rewriting for redirection, otherwise there may be problems with authentication, it is recommended to configure a reverse proxy
- If you encounter permission issues, verify that the `PUID` and `PGID` environment variables match the ownership of the mounted directories on your host system
#### Limitations
- Does not support desktop and mobile application connections, only supports use on browsers
- Export to PDF, HTML and Word formats is not supported
- Import Markdown file is not supported

### Installation
The CLI binary is `<install-dir>/resources/kernel/SiYuan-Kernel`, invoked via the `siyuan` command.
- **Windows**: the installer automatically adds the kernel directory to `PATH`, so `siyuan` works out of the box. The Microsoft Store edition runs in an MSIX sandbox and cannot modify `PATH`; deploy a `siyuan.cmd` shim once (survives Store updates):
```powershell
# Microsoft Store edition only — run once in PowerShell
$shimDir = "$env:LOCALAPPDATA\Microsoft\WindowsApps" # already in PATH by default
@(
'@echo off'
'setlocal'
'set "ROOT="'
'for /f "delims=" %%i in (''powershell -NoProfile -Command "(Get-AppxPackage *SiYuan*).InstallLocation"'') do set "ROOT=%%i"'
'if not defined ROOT goto :noshim'
'"%ROOT%\app\resources\kernel\SiYuan-Kernel.exe" %*'
'exit /b %ERRORLEVEL%'
':noshim'
'1>&2 echo siyuan: Microsoft Store edition not found'
'exit /b 1'
) | Set-Content "$shimDir\siyuan.cmd"
```
To remove on uninstall: `Remove-Item "$env:LOCALAPPDATA\Microsoft\WindowsApps\siyuan.cmd"`.
- **macOS**: create a symlink after installing:
```bash
ln -s /Applications/SiYuan.app/Contents/Resources/kernel/SiYuan-Kernel /usr/local/bin/siyuan
```
- **Linux**: create a symlink after installing:
```bash
ln -s <install-dir>/resources/kernel/SiYuan-Kernel /usr/local/bin/siyuan
```

### What if some blocks (such as paragraph blocks in list items) cannot find the block icon?
The block icon is omitted for the first sub-block under the list item. You can move the cursor into this block and trigger its block menu with <kbd>Ctrl+/</kbd> .
### What should I do if the data repo key is lost?
- If the data repo key is correctly initialized on multiple devices previously, the key is the same on all devices and can be retrieved in <kbd>Settings</kbd> - <kbd>Account & Sync</kbd> - <kbd>Local Data Repo</kbd> - <kbd>Data repo key</kbd> - <kbd>Copy key string</kbd>
- If it has not been configured correctly before (for example, the keys on multiple devices are inconsistent) or all devices are unavailable and the key string cannot be obtained, you can reset the key by following the steps below:
1. Manually back up the data, you can use <kbd>Export Data</kbd> or directly copy the <kbd>workspace/data/</kbd> folder on the file system
2. <kbd>Settings</kbd> - <kbd>Account & Sync</kbd> - <kbd>Local Data Repo</kbd> - <kbd>Data repo key</kbd> - <kbd>Reset data repo</kbd>
3. Reinitialize the data repo key. After initializing the key on one device, other devices import the key
4. The cloud uses the new synchronization directory, the old synchronization directory is no longer available and can be deleted
5. The existing cloud snapshots are no longer available and can be deleted
