Hello!
I know how to add the hosts via die inventory ini and GitHub, but i have no success until now with yml/yaml. i used a simple onne from here but i get the error tha yaml file would be no yaml file:

[WARNING]:  * Failed to parse /runner/project/add_nagios-ssh-rsa.yaml with yaml
plugin: We were unable to read either as JSON nor YAML, these are the errors we
got from each: JSON: Expecting value: line 1 column 1 (char 0)  Syntax Error
while loading YAML.   did not find expected node content  The error appears to
be in '/runner/project/add_nagios-ssh-rsa.yaml': line 1, column 1, but may be
elsewhere in the file depending on the exact syntax problem.  The offending
line appears to be:   ... ^ here

The yaml:

...
  hosts:
    Nagios_3_0_6:
#      ansible_ssh_common_args: "HostKeyAlgorithms=ssh-rsa"
      ansible_host: 192.168.150.20

Thank you for your Input again!

How about below ?

all:
  hosts:
    Nagios_3_0_6:
#      ansible_ssh_common_args: "HostKeyAlgorithms=ssh-rsa"
      ansible_host: 192.168.150.20

Documentation on ... is probably an ellipsis. This causes invalid yaml errors.

Unless Iā€™m mistaken, the ellipses is actually the symbol for the end of a yaml document. The interpreter will not look past that symbol.

This file shows 1 box running 3 servers and creates 3 groups against which plays can be written.

  all: 
    children: 
      admin_node: 
        hosts: 
          node1admin: ''

        hosts: 
          node1managed1: '' 
          node1managed2: '' 
      os_servers: 
        hosts: 
          node1.aepsc.com: '' 
    hosts:
