Hi

I am having a lot of trouble setting up this plugin. My setup: I am running Rundeck inside a Kubernetes cluster, which I wish to manage using the same Rundeck. Furthermore, I want to use the same Rundeck to run commands and kubernetes jobs on the same cluster.

I have not succeeded in showing the kubernetes nodes as well as configuring the run of a simple "hello world" kubernetes job.

In the authentication section I have the following: Cluster URL: mylab-master01.mylab.lab Token: Token String of default token from kubernetes Verify SSL: Unchecked SSL Certificate Path: Blank

The following is the output of my job running.

Hi @YoavNordmann

Did you try to use the Cluster URL like http://mylab-master01.mylab.lab ?

Thanks Luis

ltamaster commented 6 years ago

Hi @YoavNordmann

I reproduced, you need to use http:// o https:// on the URL

I was struggling with this error as well

I found the following:

  1. Use the value set for kubectl, it just works, which you can find like this:
$ cat ~/.kube/config | grep server:
    server: https://192.168.99.101:8443
  1. Note that the kubectl proxy entrypoint does not work (could not isolate why).

I had to remove a change made in version 1.0.3 Specifically line 72: "c.assert_hostname = False".

After this change it worked !

ltamaster commented 6 years ago

Hey @YoavNordmann, where is your cluster located? I added that because I found an issue with glcoud.

Thanks Luis

YoavNordmann commented 6 years ago

I am running minikube on my laptop, and our testing kube is an on premise kubernetes cluster. no amazon, no google, no nothing...

Still facing this issue, with from rundeck 3.2.9 ~ 3.3.3 and latest plug 2.0.1 Tried URL both with http or https and /root/.kube/config only, not working.

Hi, I have commented out the assert_hostname from main... and it works for me... def main(): .. c.assert_hostname = False Configuration.set_default(c) ..

Hi @pshycomore assert_hostname-not-found ,

Thank you very much for you reply!

I searched pods-resource-model.py but cannot found these lines, would you pls tell me which file it's in?

Thank you very much!

I updated common.py as your suggestion, it's works now. Thank you very much! Do you know if there some other impact if we comments it out?

halradaideh commented 3 years ago

I am facing this issue on RunDeck 3.3.4 with python 3.6 and kubernetes plugin version 2.0.1

@ltamaster

halradaideh commented 3 years ago

removing the two following lines solved the issue

c.assert_hostname = False
Configuration.set_default(c)

can this fix be merged to the master and have new release ?

pshycomore commented 3 years ago

Hi, I have been working on the examples/pods_exec.py Assert_hostname is suppose to check if the name is in the SSLcertificate. But for most of us we just connect locally. So in our client calls we can bypass. Also this combination:

def main(): c = Configuration() Configuration.set_default(c) config.load_kube_config() c.assert_hostname = False core_v1 = core_v1_api.CoreV1Api() exec_commands(core_v1)

Would sound better to me as we initialize, and the complement with the load_kube_config. This strangely works, but it looks like the c.assert_hostname has really no effect. For the moment, I would recommend to bypass and if needed check the SSL certificate hostname in an other way. This may be a urllib3 bug...

in short replace by: def main(): config.load_kube_config()
core_v1 = core_v1_api.CoreV1Api() exec_commands(core_v1) Cos kube config has all the connexion details.
