Fortio is a config auto wiring module at CrowdStrike. Fortio means cargo in Greek, configs are our cargo that needs to be loaded and carried along in our services. Fortio is used to auto wire configurations from multiple sources like environment variables, config files, HTTP endpoints etc and follows the precedence order as viper into predefined defined config structs at startup. Fortio makes use of cobra and viper to achieve some of these features and not reinvent the wheel, but Fortio is also designed in such a way that replacing cobra or viper to a different solution should be easier and seamless.
Get Fortio
et github.com/CrowdStrike/fortio
Define your config that must be auto wired
rt (
"encoding/json"
"github.com/CrowdStrike/fortio"
"gopkg.in/yaml.v2"
ExampleConfig struct {
Timeout fortio.Duration `config:"env=TIMEOUT,default=100ms;usage=Timeout for service" json:"timeout"`
Name string `config:"default=;usage=Name of service" json:"name"`
alidates assigned config values
(ec *ExampleConfig) Validate() error {
if ec.Timeout.Duration > time.Duration(100) * time.Millisecond {
return errors.New("Timeout can't be greater than 100ms")
}
if ec.Name == "" {
return errors.New("Name can't be empty")
}
return nil
umpJSON will return JSON marshalled string of config
(ec *ExampleConfig) DumpJSON() (string, error) {
v, err := json.Marshal(ec)
return string(v), err
umpYAML will return YAML marshalled string of config
(ec *ExampleConfig) DumpYAML() (string, error) {
v, err := yaml.Marshal(ec)
return string(v), err
In your main file
rt "github.com/CrowdStrike/fortio"
main() {
// Initialize empty config as pointer
config := &ExampleConfig{}
// Initialize config manager
cm := fortio.NewConfigManager("fortio-test", "My Fortio example")
// Pass config pointer to be loaded from env variables
err := cm.Load(config)
if err != nil {
// handle error
}
// validate configs loaded
err = config.Validate()
if err != nil {
// handle error
}
