Como criar, iniciar e configurar uma instância do Amazon EC2 usando um script simples do Ansible? (gerar VM remotamente)
Publicados: 2019-05-11
A Amazon AWS é sem dúvida a best public cloud que existe. Conforme discutimos nos tutoriais anteriores, o Ansible é uma ferramenta muito útil para os administradores de sistemas manterem a infraestrutura da empresa.
Neste tutorial, veremos as etapas sobre como criar, iniciar e configurar uma instância do Amazon EC2 usando scripts simples do Ansible.
Detalhes:
- especifique instance_type:
t2.micro - especifique security_group:
crunchify_security_grp- Altere o grupo de segurança conforme sua necessidade.
- especifique a imagem:
ami-crunchify231di- Você precisa criar Amazon Image antes de executar isso.
- especifique o par de chaves:
crunchify- Esta é a sua chave de segurança para login sem senha.
- escolha a região padrão:
us-east-2- Região padrão que eu recomendaria.
- número de VMs que você deseja iniciar: 1
- comece com VM 1.
- criar grupo de firewall básico
- criar instância do Amazon EC2
- Espere por exemplo para aparecer
- Obtenha o endereço IP e salve no arquivo crunchify.txt
- você precisa criar crunchify.txt antes de executar este script ansible.
- Marque a instância recém-criada como crunchify
Passo 1)
Instale o ansible no macOS. Verifique se você configurou o Ansible da maneira correta
Passo 2)
Você precisa exportar sua AWS Access Key e Secret Access Key . Siga o tutorial sobre como configurar a Amazon AWS CLI para obter suas chaves.

export AWS_ACCESS_KEY_ID = JHKHLJLHJHJK2SHIY27AIF export AWS_SECRET_ACCESS_KEY = QLKJDKIAYXNIWN2ZHIY27AI54345HKLHJ |
Etapa 3) Crie o arquivo crunchify-host

[ local ] localhost ansible_connection = local ansible_python_interpreter = python |
Etapa 4) Crie o arquivo crunchify-ec2.yml

Vamos verificar se a nova instância foi criada com sucesso com todas as nossas especificações
Acesse o Amazon AWS console para verificar a instância.
Link: https://us-east-2.console.aws.amazon.com/ec2/v2/home?region=us-east-2#Instances:sort=instanceId
Certifique-se de verificar todas as suas configurações.
Verifique suas Etiquetas. Isso é muito útil se você estiver lidando com hundreds of instances .
Verifique o arquivo crunchify.txt que tem o IP dos hosts recém-criados:

bash3 . 2 $ cat crunchify . txt 18.217.28.189 |
É isso. Parabéns. Você acabou de criar e iniciar uma nova instância do EC2 na nuvem Amazon AWS remotamente usando o Ansible.
Deixe-me saber se você enfrentar algum problema ao criar instância na nuvem do Amazon EC2.
