Hi All,

Could do with some help with this one, I'm currently trying to use Kubernetes to build containers for jobs that will run within Jenkins. I'm currently having the issue where my Docker File  has Ansible installed but, for some reason,it's not able to run if the Container is built with Jenkins

Hi,

Could I suggest you to install at least Python 3.6 and not 3.3?

David,

Looks like your issue isn't with the dockerfile, but with ansible. The failure is listed as `ansible: not found`. Make sure your executor has ansible and its in the path. Note the user and directory jenkins is running the command in.

When jenkins deploys the pod jnlp container along with my ansible container is created within that Pod,

My docker file is using Ubuntu should I be using the jenkins/jnlp image instead.

If I keep the pod after the jobs fails and execute shell a d run which ansible is shows the path

David, 

It sounds like you might not be running the step inside the right container. By default steps are runin the jnlp container. You need to specify `container('container-name') {` for which container to run in. See the documentation: https://plugins.jenkins.io/kubernetes/

Hi Nigel

I'm using FreeStyle Project. 

I have selected restricted to run on Node: Ansible

Am I correct that pipelines are only supported and not Freestyle? 

I created a Test Pipeline, and am able to see the ansible version when I ran "sh 'ansible --version'" 

so it appears the freestyle is using the JNLP container.
