Hello,

Trying to apply a yaml definition using the k8s module to my cluster. I’ve never used this module before so i’m trying to work out if i’m just doing something wrong or is this a bug?

I figured it out. I had the path to my kubeconfig set wrong and i was missing ‘context’ and namespace parameters. What finally worked:

`

- hosts: kube-master[0]  
become: no  
tasks:
- name: Install simple app  
k8s:  
definition: ‘{{ item }}’  
kubeconfig: ~/.kube/config-dev  
context: dev  
namespace: default  
state: absent  
with\_items: ‘{{ lookup(“url”, “[https://k8s.io/examples/application/guestbook/redis-master-deployment.yaml](https://k8s.io/examples/application/guestbook/redis-master-deployment.yaml)”, split\_lines=False) | from\_yaml\_all | list }}’  
when: item is not none  
delegate\_to: localhost
