Question

我对这个ansible playbook的目标是根据已经运行的内容启动8个ec2实例。我在查找信息时遇到问题的部分是按顺序命名/标记实例。有没有办法让tag_Name成为ansible-test-1到8？

以下是我所拥有的：

- name: Provision EC2 instances
      ec2:
        key_name: "{{ aws_public_key }}"
        instance_type: t2.small
        image: "{{ aws_ubuntu_ami }}"
        wait: true
        vpc_subnet_id: "{{ dev_subnet_public }}"
        group_id: "{{ aws_group }}"
        assign_public_ip: yes
        instance_tags:
          Name: ansible-test
          environment: qa
        exact_count: 8
        count_tag:
          Name: ansible-test*
        region: "{{ aws_region }}"
        volumes:
          - device_name: /dev/sda1
            volume_size: 300
      register: ec2

Answer 1

试试这个：

- name: Provision EC2 instances
      ec2:
        key_name: "{{ aws_public_key }}"
        instance_type: t2.small
        image: "{{ aws_ubuntu_ami }}"
        wait: true
        vpc_subnet_id: "{{ dev_subnet_public }}"
        group_id: "{{ aws_group }}"
        assign_public_ip: yes
        instance_tags:
          Name: ansible-test-{{item}}
          environment: qa
        count: 1
        region: "{{ aws_region }}"
        volumes:
          - device_name: /dev/sda1
            volume_size: 300
      register: ec2
      with_items:
        - 1
        - 2
        .....
        - 8

另一种方法是使用ec2_tag

在下一个任务中创建实例后修改标记

使用with_sequence

示例：

- name: Provision EC2 instances
  ec2:
    key_name: "{{ aws_public_key }}"
    instance_type: t2.small
    image: "{{ aws_ubuntu_ami }}"
    wait: true
    vpc_subnet_id: "{{ dev_subnet_public }}"
    group_id: "{{ aws_group }}"
    assign_public_ip: yes
    instance_tags:
      Name: ansible-test-{{item}}
      environment: qa
    with_sequence:
      count: 8
    exact_count: 8
    count_tag:
      Name: ansible-test*
    region: "{{ aws_region }}"
    volumes:
      - device_name: /dev/sda1
        volume_size: 300
  register: ec2

在ansible playbook中设置顺序标记名称多个ec2实例
