Overview ¶
Package config contains functionality for interacting with ComponentConfig files
DeferredFileLoader ¶
This uses a deferred file decoding allowing you to chain your configuration setup. You can pass this into manager.Options#File and it will load your config.

Types ¶
type ControllerManagerConfiguration ¶
type ControllerManagerConfiguration interface {
runtime.Object
// Complete returns the versioned configuration
Complete() (v1alpha1.ControllerManagerConfigurationSpec, error)
}
ControllerManagerConfiguration defines the functions necessary to parse a config file and to configure the Options struct for the ctrl.Manager
type DeferredFileLoader ¶
type DeferredFileLoader struct {
ControllerManagerConfiguration
// contains filtered or unexported fields
}
DeferredFileLoader is used to configure the decoder for loading controller runtime component config types
Example (AtPath) ¶
This example will load the file from a custom path
package main
import (
"fmt"
"os"
"github.com/binoue/controller-runtime/pkg/config"
)
func main() {
loader := config.File().AtPath("/var/run/controller-runtime/config.yaml")
_, err := loader.Complete()
if err != nil {
fmt.Println("failed to load config")
os.Exit(1)
}
}
Example (InjectScheme) ¶
This example sets up loader with a custom scheme
package main
import (
"fmt"
"os"
"github.com/binoue/controller-runtime/pkg/config"
"k8s.io/apimachinery/pkg/runtime"
"github.com/binoue/controller-runtime/examples/configfile/custom/v1alpha1"
)
var scheme = runtime.NewScheme()
func init() {
_ = v1alpha1.AddToScheme(scheme)
}
func main() {
loader := config.File()
err := loader.InjectScheme(scheme)
if err != nil {
fmt.Println("failed to inject scheme")
os.Exit(1)
}
_, err = loader.Complete()
if err != nil {
fmt.Println("failed to load config")
os.Exit(1)
}
}
Example (OfKind) ¶
This example sets up the loader with a custom scheme and custom type
package main
import (
"fmt"
"os"
"github.com/binoue/controller-runtime/pkg/config"
"k8s.io/apimachinery/pkg/runtime"
"github.com/binoue/controller-runtime/examples/configfile/custom/v1alpha1"
)
var scheme = runtime.NewScheme()
func init() {
_ = v1alpha1.AddToScheme(scheme)
}
func main() {
loader := config.File().OfKind(&v1alpha1.CustomControllerManagerConfiguration{})
err := loader.InjectScheme(scheme)
if err != nil {
fmt.Println("failed to inject scheme")
os.Exit(1)
}
_, err = loader.Complete()
if err != nil {
fmt.Println("failed to load config")
os.Exit(1)
}
}
func File ¶
func File() *DeferredFileLoader
File will set up the deferred file loader for the configuration this will also configure the defaults for the loader if nothing is
Defaults:
Path: "./config.yaml" Kind: GenericControllerManagerConfiguration
Example ¶
This example will load a file using Complete with only defaults set.
package main
import (
"fmt"
"os"
"github.com/binoue/controller-runtime/pkg/config"
)
func main() {
// This will load a config file from ./config.yaml
loader := config.File()
_, err := loader.Complete()
if err != nil {
fmt.Println("failed to load config")
os.Exit(1)
}
}
func (*DeferredFileLoader) AtPath ¶
func (d *DeferredFileLoader) AtPath(path string) *DeferredFileLoader
AtPath will set the path to load the file for the decoder
func (*DeferredFileLoader) Complete ¶
func (d *DeferredFileLoader) Complete() (v1alpha1.ControllerManagerConfigurationSpec, error)
Complete will use sync.Once to set the scheme
func (*DeferredFileLoader) InjectScheme ¶
func (d *DeferredFileLoader) InjectScheme(scheme *runtime.Scheme) error
InjectScheme will configure the scheme to be used for decoding the file
func (*DeferredFileLoader) OfKind ¶
func (d *DeferredFileLoader) OfKind(obj ControllerManagerConfiguration) *DeferredFileLoader
OfKind will set the type to be used for decoding the file into
