What happened?

Only exit code of kubectl config delete-user is 1

$ kubectl config delete-cluster || echo $?
Delete the specified cluster from the kubeconfig.

Examples:
  # Delete the minikube cluster
  kubectl config delete-cluster minikube

Usage:
  kubectl config delete-cluster NAME [options]

Use "kubectl options" for a list of global command-line options (applies to all commands).

$ kubectl config delete-context || echo $?
Delete the specified context from the kubeconfig.

Examples:
  # Delete the context for the minikube cluster
  kubectl config delete-context minikube

Usage:
  kubectl config delete-context NAME [options]

Use "kubectl options" for a list of global command-line options (applies to all commands).

$ kubectl config delete-user || echo $?
error: user to delete is required

What exit code is expected here?

Technically I think the convention is for usage errors to exit with code 2, but kubectl doesn't do that. Instead it exits with 1 in the cases I have seen, sometimes printing the usage, but sometimes not. But in either case, the exit code has been 1.

~ $ kubectl get
You must specify the type of resource to get. Use "kubectl api-resources" for a complete list of supported resources.

error: Required resource not specified.
Use "kubectl explain <resource>" for a detailed description of that resource (e.g. kubectl explain pods).
See 'kubectl get -h' for help and examples
~ $ echo $?
1
~ $ 
~ $ 
~ $ kubectl label
error: one or more resources must be specified as <resource> <name> or <resource>/<name>
~ $ echo $?
1
~ $ 
~ $ 
~ $ kubectl create
Error: must specify one of -f and -k

Create a resource from a file or from stdin.

 JSON and YAML formats are accepted.

Examples:
  # Create a pod using the data in pod.json
  kubectl create -f ./pod.json
  
  # Create a pod based on the JSON passed into stdin
  cat pod.json | kubectl create -f -
  
  # Edit the data in registry.yaml in JSON then create the resource using the edited data
  kubectl create -f registry.yaml --edit -o json

Available Commands:
  clusterrole           Create a cluster role
  clusterrolebinding    Create a cluster role binding for a particular cluster role
  configmap             Create a config map from a local file, directory or literal value

Options:
    --allow-missing-template-keys=true:
	If true, ignore any errors in templates when a field or map key is missing in the template. Only applies to
	golang and jsonpath output formats.

    --dry-run='none':
	Must be "none", "server", or "client". If client strategy, only print the object that would be sent, without
	sending it. If server strategy, submit server-side request without persisting the resource.

    --edit=false:
	Edit the API resource before creating

    --field-manager='kubectl-create':
	Name of the manager used to track field ownership.

    -f, --filename=[]:
	Filename, directory, or URL to files to use to create the resource

    -k, --kustomize='':
	Process the kustomization directory. This flag can't be used together with -f or -R.

    -o, --output='':
	Output format. One of: (json, yaml, name, go-template, go-template-file, template, templatefile, jsonpath,
	jsonpath-as-json, jsonpath-file).

    --raw='':
	Raw URI to POST to the server.  Uses the transport specified by the kubeconfig file.

    -R, --recursive=false:
	Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests
	organized within the same directory.

    --save-config=false:
	If true, the configuration of current object will be saved in its annotation. Otherwise, the annotation will
	be unchanged. This flag is useful when you want to perform kubectl apply on this object in the future.

    -l, --selector='':
	Selector (label query) to filter on, supports '=', '==', and '!='.(e.g. -l key1=value1,key2=value2). Matching
	objects must satisfy all of the specified label constraints.

    --show-managed-fields=false:
	If true, keep the managedFields when printing objects in JSON or YAML format.

    --template='':
	Template string or path to template file to use when -o=go-template, -o=go-template-file. The template format
	is golang templates [http://golang.org/pkg/text/template/#pkg-overview].

    --validate='strict':
	Must be one of: strict (or true), warn, ignore (or false). 		"true" or "strict" will use a schema to validate
	the input and fail the request if invalid. It will perform server side validation if ServerSideFieldValidation
	is enabled on the api-server, but will fall back to less reliable client-side validation if not. 		"warn" will
	warn about unknown or duplicate fields without blocking the request if server-side field validation is enabled
	on the API server, and behave as "ignore" otherwise. 		"false" or "ignore" will not perform any schema
	validation, silently dropping any unknown or duplicate fields.

    --windows-line-endings=false:
	Only relevant if --edit=true. Defaults to the line ending native to your platform.

Usage:
  kubectl create -f FILENAME [options]

Use "kubectl create <command> --help" for more information about a given command.
Use "kubectl options" for a list of global command-line options (applies to all commands).
