Ansible：置备新分配的ec2实例

这本剧本似乎正在SSH传输到我的本地计算机，而不是远程计算机上。根据我在底部包含的输出来猜测这种情况。

我已经从此处改编了示例：http : //docs.ansible.com/ansible/guide_aws.html#provisioning

该剧本分为两个剧本：

创建EC2实例并
EC2实例的配置

注意：要运行此代码，您需要创建一个与项目名称相同的密钥对（您可以在此处获取更多信息：https : //us-west-2.console.aws.amazon.com/ec2/ v2 / home？region = us-west-2＃KeyPairs：sort = keyName）

该剧本列在下面：

# Create instance
- hosts: 127.0.0.1
  connection: local
  gather_facts: false
  vars:
    project_name: my-test
  tasks:
    - name: Get the current username
      local_action: command whoami
      register: username_on_the_host

    - name: Capture current instances
      ec2_remote_facts:
        region: "us-west-2"
      register: ec2_instances

    - name: Create instance
      ec2:
        region: "us-west-2"
        zone: "us-west-2c"
        keypair: "{{ project_name }}"
        group:
          - "SSH only"
        instance_type: "t2.nano"
        image: "ami-59799439"  # debian:jessie amd64 hvm on us-west 2
        count_tag: "{{ project_name }}-{{ username_on_the_host.stdout }}-test"
        exact_count: 1
        wait: yes
        instance_tags:
          Name: "{{ project_name }}-{{ username_on_the_host.stdout }}-test"
          "{{ project_name }}-{{ username_on_the_host.stdout }}-test": simple_ec2
          Creator: "{{ username_on_the_host.stdout }}"
      register: ec2_info

    - name: Wait for instances to listen on port 22
      wait_for:
        state: started
        host: "{{ item.public_dns_name }}"
        port: 22
      with_items: "{{ ec2_info.instances }}"
      when: ec2_info|changed

    - name: Add new instance to launched group
      add_host:
        hostname: "{{ item.public_dns_name }}"
        groupname: launched
      with_items: "{{ ec2_info.instances }}"
      when: ec2_info|changed

    - name: Get ec2_info information
      debug:
        msg: "{{ ec2_info }}"

# Configure and install all we need
- hosts: launched
  remote_user: admin
  gather_facts: true
  tasks:
    - name: Display all variables/facts known for a host
      debug:
        var: hostvars[inventory_hostname]

    - name: List hosts
      debug: msg="groups={{groups}}"

    - name: Get current user
      command: whoami

    - name: Prepare system
      become: yes
      become_method: sudo
      apt: "name={{item}} state=latest"
      with_items:
        - software-properties-common
        - python-software-properties
        - devscripts
        - build-essential
        - libffi-dev
        - libssl-dev
        - vim

我的输出是：

TASK [Get current user] ********************************************************

这应该工作。
