No access to file error while running the playbook

[karaleina]

Hello,

I downloaded this repository. In my case, I use only one node (master node as master and worker node). So, I have such a hosts.ini file:

[master]
172.x.x.5

[kube-cluster:children]
master

[default]
ansible_become=true
ansible_user='<my_user_name>'
ansible_become_method='sudo'
ansible_become_user='kubernetes'

...as I need to log as the sudo, but not root user ('kubernetes' user).

I am getting such an error (console log):

 [WARNING]: Invalid characters were found in group names but not replaced, use
-vvvv to see details
