Docker Swarm: Instalar Ansible AWX

Hoy os vamos a enseñar otro proyecto open source de automatización, Ansible AWX.

Comentar que Ansible AWX es la versión gratuita de Red Hat Ansible Tower.

Para los que no os suene, AWX es un proyecto que nos permite administrar proyectos de Ansible de una forma gráfica. AWX se aloja en GitHub y proporciona una interfaz de usuario basada en la web, REST API, y un motor de tareas para Ansible.

WEBS PROYECTO OFICIAL:

PROYECTOS QUE PODEIS USAR (yo lo haré con el segundo):

Teniendo esta pequeña pincelada, vamos a implementarlo en contenedores, bajo una infraestructura Docker Swarm con Debian.

Os explico mi laboratorio de Docker Swarm con un par de comandos. Os enseño los nodos y la versión de Docker que voy a utilizar:

Bajamos el repositorio generando una carpeta para los ficheros:

root@swarm00:~/awx# git clone https://github.com/tomwillfixit/awx-on-swarm.git
Clonando en 'awx-on-swarm'...
remote: Enumerating objects: 30, done.
remote: Total 30 (delta 0), reused 0 (delta 0), pack-reused 30
Desempaquetando objetos: 100% (30/30), listo.

Desempaquetando objetos: 100% (30/30), listo.

Cambiamos al repo y primero lanzaremos la creación de postgres:

root@swarm00:~/awx# cd awx-on-swarm/
root@swarm00:~/awx/awx-on-swarm# docker stack deploy -c ./postgres.yml awx

1 2	root@swarm00:~/awx# cd awx-on-swarm/ root@swarm00:~/awx/awx-on-swarm# docker stack deploy -c ./postgres.yml awx

Ahora la red y el servicio para el proyecto:

root@swarm00:~/awx/awx-on-swarm# docker stack deploy -c ./postgres.yml awx
Creating network awx_network
Creating service awx_postgres

root@swarm00:~/awx/awx-on-swarm# docker stack deploy -c ./postgres.yml awx

Creating network awx_network

Creating service awx_postgres

Comprobamos el servicio:

root@swarm00:~/awx/awx-on-swarm# docker stack ls

awx               1          Swarm

root@swarm00:~/awx/awx-on-swarm# docker stack ls

NAME SERVICES ORCHESTRATOR

awx 1 Swarm

portainer-agent 1 Swarm

Verificar que todo está en orden:

root@swarm00:~/awx/awx-on-swarm# docker service ls
