Hi @bernalhd, we were discussing about it on slack.

Note: Using Ubuntu hypervisor, I ran KubeInit OKD against it and it ran well until the task for update packages on okd-service-01:

failed: [hypervisor-01 -> 10.10.10.10] (item=okd-service-01) => {"ansible_loop_var": "item", "changed": false, "item": "okd-service-01", "module_stderr": "Shared connection to 10.10.10.10 closed.\r\n", "module_stdout": "/bin/sh: /usr/bin/python3: No such file or directory\r\n", "msg": "The module failed to execute correctly, you probably need to set the interpreter.\nSee stdout/stderr for the exact error", "rc": 127}

The okd-service-01 inventory by default is set to install CentOS 8 Core, which does not have python3 installed by default. It did get some form of python (via KubeInit?), but not in /usr/bin/python3, rather /usr/libexec/platform-python. I did not know that Ansible supported per-host interpreter settings, so I will go with that for a permanent solution. I worked around the issue by setting the inventory interpreter path to match CentOS settings, then symlinked it on the ubuntu host as a test, which worked. As it stands, unless the hypervisor and guests support the same interpreter path, the inventory will require per-host interpreter vars. (I think)

What distro are you using in the hypervisor? I can bet is different from CentOS :)

@bernalhd, Please feel free to ask any questions you have, and if you find any issue also feel free to raise issues in the project's repo (https://www.github.com/kubeinit/kubeinit). Also, it would be awesome if you can star the project to catch up with updates and new features.

The workaround works fine! I'm using ubuntu focal (moving to bionic) as hypervisor right now.

If anything else is required I'm closing this, please feel free to reopen if more info is required or if you have a different approach also feel free to raise a PR for having it integrated.
