k8s inventory plugin not working

[603627156]

Im trying to create a dynamic inventory from a kubernetes cluster, using the k8s plugin, however I'm unable to get it to work. It's not good to configure according to the document. How to configure？

1、deploy

I'm not sure why you'd need to use the k8s inventory plugin for this particular play—it's operating on a server (192.168.10.130 I presume) that is running Kubernetes, and the way the kubernetes module works, your setting of connection: local seems to indicate it should just work with normal inventory.

How are you configuring the k8s inventory plugin to be used? Can you give more of the contents of /etc/ansible/hosts?

Hello,

I don't understand what is your problem. Dumping lot of content does not help.

Could you state clearly and shortly what you would like to achieve, how do you do that and what you get ?

[Akasurde]

@603627156 There is typo in your kubeconfig. Username should be 'cluster-admin' instead of 'cluser-admin' in contexts.

...
- context:
    cluster: kubernetes
    user: cluser-admin
...

kubernetes Python library is not providing actual error. The following PR will change this behavior - kubernetes-client/python-base#201
