Creacion del Alicante Puppet Users Group

Llevaba ya tiempo dandole vueltas a la idea de montar un grupo de usuarios de puppet en Alicante, que no se si habra muchos…

La semana pasada mande un correo a la lista de usuarios de puppet por si habia alguien interesado y hoy he recibido un correo de puppetlabs.com indicandome que si tenia un grupo de meetup, que ellos me pondrian un link en su web. por lo que me he decidido a crear un group en meetup.com.

Por lo que oficialemente hoy ha sido creado el Alicante Puppet Users Group

Asi que si estas interesado en Puppet, DevOps, Data Center and Operations Automation y basicamente hacer las cosas una sola vez y que los ordenadores hagan el resto. Este es tu grupo.

Espero que os apunteis y cuando seamos unos cuantos hagamos la primera quedada.
