|
## Configuration
|
|
|
|
There are three ways to configure Sablier:
|
|
|
|
1. [In a configuration file](#configuration-file)
|
|
2. [As environment variables](#environment-variables)
|
|
3. [As command-line arguments](#arguments)
|
|
|
|
Configuration sources are evaluated in the order listed above.
|
|
|
|
If no value is provided for a given option, a default value is used.
|
|
|
|
### Configuration File
|
|
|
|
At startup, Sablier searches for a configuration file named sablier.yml (or sablier.yaml) in:
|
|
|
|
- `/etc/sablier/`
|
|
- `$XDG_CONFIG_HOME/`
|
|
- `$HOME/.config/`
|
|
- `.` *(the working directory)*
|
|
|
|
You can override this using the `configFile` argument.
|
|
|
|
```bash
|
|
sablier --configFile=path/to/myconfigfile.yml
|
|
```
|
|
|
|
```yaml
|
|
provider:
|
|
# Provider to use to manage containers (docker, swarm, kubernetes)
|
|
name: docker
|
|
server:
|
|
# The server port to use
|
|
port: 10000
|
|
# The base path for the API
|
|
base-path: /
|
|
storage:
|
|
# File path to save the state (default stateless)
|
|
file:
|
|
sessions:
|
|
# The default session duration (default 5m)
|
|
default-duration: 5m
|
|
# The expiration checking interval.
|
|
# Higher duration gives less stress on CPU.
|
|
# If you only use sessions of 1h, setting this to 5m is a good trade-off.
|
|
expiration-interval: 20s
|
|
logging:
|
|
level: debug
|
|
strategy:
|
|
dynamic:
|
|
# Custom themes folder, will load all .html files recursively (default empty)
|
|
custom-themes-path:
|
|
# Show instances details by default in waiting UI
|
|
show-details-by-default: false
|
|
# Default theme used for dynamic strategy (default "hacker-terminal")
|
|
default-theme: hacker-terminal
|
|
# Default refresh frequency in the HTML page for dynamic strategy
|
|
default-refresh-frequency: 5s
|
|
blocking:
|
|
# Default timeout used for blocking strategy (default 1m)
|
|
default-timeout: 1m
|
|
```
|
|
|
|
### Environment Variables
|
|
|
|
Environment variables follow the same structure as the configuration file. For example:
|
|
|
|
```yaml
|
|
strategy:
|
|
dynamic:
|
|
custom-themes-path: /my/path
|
|
```
|
|
|
|
becomes
|
|
|
|
```bash
|
|
STRATEGY_DYNAMIC_CUSTOM_THEMES_PATH=/my/path
|
|
```
|
|
|
|
### Arguments
|
|
|
|
To list all available arguments:
|
|
|
|
<!-- x-release-please-version-end -->
|
|
```bash
|
|

|
|
|

|
|
|
docker run sablierapp/sablier:1.10.1 --help
|
|
```
|
|
<!-- x-release-please-end -->
|
|
|
|
Command-line arguments follow the same structure as the configuration file. For example:

```yaml
|
|
strategy:
|
|
dynamic:
|
|
custom-themes-path: /my/path
|
|
```
