Hey I m trying to execute a playbook but I get the following error

Question

ERROR! Syntax Error while loading YAML.
  mapping values are not allowed in this context

The error appears to have been in '/etc/ansible/playbooks/hostname.yml': line 3, column 7, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

-hosts: all
 tasks:
      -command: hostname

Answer 1

Hey, you have a syntax error as mentioned in the error log. There should be a space between '-' and command and between '-' and hosts.

Replace it with the following:

- hosts: all
  tasks:
       - command: hostname
