How to debug many nodes in the emergency (or not)?
summary
Ansible-console runs against an inventory (example: 5 hosts, 3 front-end, 2 back-end) and executes multiple tasks with configurable forks (demo uses 10 forks, can set to 1). It keeps task history and gathers facts then reuses them inside shell commands to, for example, cat /etc/motd per host. Demo attempts installing httpd on front-ends and returns “nothing to do.” The tool replaces pssh/clusterssh for one-off debugging and offers autocomplete, help, and group selection.
