A service health dashboard in Go that is meant to be used as a docker
|
|
image with a custom configuration file.

## Usage
|
|
|
|
By default, the configuration file is expected to be at `config/config.yaml`.
|
|
|
|
You can specify a custom path by setting the `GATUS_CONFIG_FILE` environment variable.
|
|
|
|
```yaml
|
|
metrics: true # Whether to expose metrics at /metrics
|
|
services:
|
|
- name: twinnation # Name of your service, can be anything
|
|
url: https://twinnation.org/health
|
|
interval: 15s # Duration to wait between every status check (default: 10s)
|
|
conditions:
|
|
- "[STATUS] == 200"
|
|
- "[RESPONSE_TIME] < 300"
|
|
- name: github
|
|
url: https://api.github.com/healthz
|
|
conditions:
|
|
- "[STATUS] == 200"
|
|
```
|
|
|
|
Note that you can also add environment variables in the your configuration file (i.e. `$DOMAIN`, `${DOMAIN}`)
