Instalando Wildfly com Ansible

Os Playboks são usados na maioria das vezes para construir interações complexas que requerem, por exemplo, provisionamento de software em máquinas remotas. Neste exemplo, veremos como
combinar nosso Playbook que irá instalar o JDK o unzip e o Wildfly, o servidor de aplicativos por sua vez será configurado no modo standalone, e, ao fim da execução do playbook o mesmo estará pronto para utilização em ambiente de teste.

Requisitos

Certifique-se que o seu host(target) possui acesso a internet, python 2.6 ou superior instalado para suportar os módulos do ansible e também algum repositório que possui o JAVA para download.

[root@ansible-master projeto-wildfly]# ls
ansible.cfg  inventory  playbook.yml  roles

Acesse o arquivo de inventário para configurar os hosts que deseja realizar a instalação do wildfly em modo standalone.

Se certifique que o acesso ssh entre seu host do ansible e os nodes está funcional.










[root@ansible-master projeto-wildfly]# ansible all -m ping
192.168.99.107 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    },
    "changed": false,
    "ping": "pong"
}

Como utilzar este Playbook

Ao baixar o arquivo .zip, descompacte no seu diretório de preferência. Após descompactar você irá se deparar com a lista arquivos abaixo:

  • ansible.cfg
  • inventory
  • playbok.yml

As tasks estão dentro do diretório roles/isweluiz.wildfly-install/tasks/main.yml.

Checando a syntax

[root@ansible-master projeto-wildfly]# ansible-playbook --syntax-check  playbook.yml

playbook: playbook.yml

Variáveis definidas

roles/isweluiz.wildfly-install/vars/main.yml

---
https_uri: https://download.jboss.org/wildfly/21.0.1.Final/wildfly-21.0.1.Final.zip
wildfly_user: wildfly

O endereço das interfaces pública e de gerenciamento serão alteradas pela variável do IPV4 padrão do host destino, "{{ ansible_default_ipv4.address }}".

 <interfaces>
        <interface name="management">
            <inet-address value="${jboss.bind.address.management:192.168.0.86}"/>
        </interface>
        <interface name="public">
            <inet-address value="${jboss.bind.address:192.168.0.86}"/>
