Recentemente a Red Hat disponibilizou de forma Open Source o codigo fonte do Ansible Tower, ferramenta web que gerencia as execucoes de playbooks do ansible através do seu novo projeto AWX.
Este é um passo-a-passo de como instalar o Ansible Tower no Debian 9 Stretch rodando em container Docker, e segue basicamente a documentacao oficial do projeto porém em uma instalacao para o Debian 9 Stretch. A instalacao das dependencias é simples, o Ansible Tower tem sua UI em nodejs, a instalacao do gettext é uma dependencia para o comando msgfmt, necessário durante a build.
# curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
# apt-get install nodejs gettext docker
# pip install ansible docker-py # (ansible 2.3)Apos a instalacao das dependencias, o processo de build dos containers é totalmente automatizado pelo proprio Ansible
$ git clone [email protected]:ansible/awx.git
# cd awx/installer && ansible-playbook -i inventory install.ymlAguarde o termino do build e entao, no comando docker ps os containers em execucao deveram parecer como estes
