Let's suppose that I have such code to generate new pod
req := &api.Pod{
TypeMeta: unversioned.TypeMeta{
Kind: "Pod",
APIVersion: "v1",
},
ObjectMeta: api.ObjectMeta{
GenerateName: "name-, // need to get that name, before creating an object
},
Spec: api.PodSpec{
Containers: []api.Container{
{
Name: "nginx",
Image: "nginx",
Env: []corev1.EnvVar{} // pass here the generated name,
},
},
},
}
...
// Do some work on the generated name, before creating the resource in Kubernetes cluster
...
err := client.Create(context.Background(), req)Is it possible to get that generated name before creating an object? Or is it possible to store that generated name in the env of the same object?
The generated name seem to be created in conjunction with the apiServer. See Issue comment and Kubernetes API Concepts - Generated values.
It is recommended to not depend on it. Typically, labels and selectors is more common in the Kubernetes ecosystem.
Env: []corev1.EnvVar{} // pass here the generated name,You can use the Downward API for this. Example:
env:
- name: POD_NAME
valueFrom:
fieldRef:
fieldPath: metadata.name
