ssh - playbook - "Disposición vagabunda" funciona, pero no puedo enviar un comando ad-hoc con Ansible

ansible playbook command

Question

Configuré una máquina con Vagrant y creé un libro de jugadas básico para Ansible. Todo funciona como se espera cuando corro

vm-abla> vagrant provision

Pero no puedo enviar un comando ad-hoc a la máquina con Ansible, ¿por qué? He resaltado la línea que creo que podría indicar la causa.

vm-abla> ansible jon -i provisioning/hosts -a "echo ''TEST''" -vvvv

Después de leer la sección Solución de problemas de esta página , también he intentado usar la clave SSH de Vagrant al agregar esto al final del comando, con un resultado muy similar:

-c ssh --private-key=~/.vagrant.d/insecure_private_key

¿Alguna idea de lo que está pasando mal? Gracias

EDITAR: ¡Ah! Pude iniciar sesión en la máquina utilizando SSH, pero tuve que declarar que era el usuario "vagabundo" en la máquina virtual, así:

ssh [email protected]

Entonces, ahora que esto funciona, ¿cómo podría hacer lo mismo con ansible? (¿o esta no sería una buena solución?)

Answer 1

Logré:

vm-abla> ansible jon -i provisioning/hosts -a "echo ''TEST''" -vvvv -c ssh --user=vagrant --private-key=~/.vagrant.d/insecure_private_key

Pero si alguien tiene una solución más elegante o segura, estoy interesado.

Answer 2

Como @mascip ya ha respondido por sí mismo, debe indicar ansible: inventory_file, ssh_user y ssh_private_key. (No creo que se necesite la configuración -c ssh ).

La "manera elegante" es poner todos esos ajustes en un archivo ansible.cfg específico del proyecto. Entonces solo puedes ejecutar ansible jon -a "echo ''TEST''" .

Una "sorpresa" es que ansible.cfg debe estar en el mismo directorio donde está ejecutando el comando ansible . Me gusta poner ansible.cfg en mi directorio de ansible, así que eso significa que necesito hacer cd allí primero. Si desea ejecutar ansible desde la raíz de su proyecto, coloque ansible.cfg allí (y ajuste las rutas relativas en el archivo de configuración de muestra a continuación).

ansible.cfg:

[defaults]
remote_user = vagrant
private_key_file = ~/.vagrant.d/insecure_private_key
# aka inventory file
hostfile = ../.vagrant/provisioners/ansible/inventory/vagrant_ansible_inventory
