Function Deployment
A sample function is in config/samples/sample.yaml
A Goless function looks like this:
apiVersion: goless.io/v1beta1
kind: Function
metadata:
name: function-example
spec:
service: "example"
serverPort: 9000
replicas: 1
function: |
package handlers
import (
"net/http"
)
func Handler(w http.ResponseWriter, r *http.Request) {
w.Write([]byte("Hey this example works!"))
}Since this is the default Go HTTP package we can include middleware as well:
apiVersion: goless.io/v1beta1
kind: Function
metadata:
name: function-example
spec:
service: "example"
serverPort: 9000
replicas: 1
function: |
package handlers
import (
"net/http"
)
func Handler(w http.ResponseWriter, r *http.Request) {
w.Header().Add("foo", "bar")
Foo().ServeHTTP(w, r)
}
func Foo() http.HandlerFunc {
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
w.Write([]byte("in handler"))
})
}
