How to use field_selector

See original GitHub issue

hi,I want to list service in specified namespace. I call list_namespaced_service,but output error. This is my code:


field_selector = {'spec.selector': label}   //label:   {u'app': 'admin-test'}
service = v1.list_namespaced_service(namespace='default', pretty='true', field_selector=field_selector, watch=False)

error:

ApiException: (500)
Reason: Internal Server Error
HTTP response headers: HTTPHeaderDict({'Date': 'Wed, 05 Apr 2017 03:57:23 GMT', 'Content-Length': '240', 'Content-Type': 'application/json'})
HTTP response body: {
  "kind": "Status",
  "apiVersion": "v1",
  "metadata": {},
  "status": "Failure",
  "message": "invalid selector: '{'spec.selector': {u'app': 'admin-test'}}'; can't understand '{'spec.selector': {u'app': 'admin-test'}}'",
  "code": 500
}

I ran into this as well.

Reading the docs shows it is a str, but doesn’t give a good, valid, example of it anywhere.

This gets appended to a dictionary of items to pass into a raw request call down the line, in which kubernetes expects it in the form of ‘key=value’. So, for example, if I’m trying to find a secret named star-cert, the following should return the object:

kube.list_namespaced_secret('default', field_selector='metadata.name=star-cert')
