Ansible：提供新分配的ec2實例

Question

本劇本似乎是在我的本地機器上而不是在遠程機器上進行SSH連接。這種情況是基於我在底部包含的輸出來猜測的。

我已經適應了例如從這裏：http://docs.ansible.com/ansible/guide_aws.html#provisioning

的劇本被分成兩個劇本：

1. 創建EC2實例和EC2實例的
2. 配置

注意：要運行此項，您需要創建一個與項目名稱相同的密鑰對（您可以獲得更多信息這裏和灰：https://us-west-2.console.aws.amazon.com/ec2/v2/home?region=us-west-2#KeyPairs:sort=keyName）

的劇本列表如下：

# 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"

     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 

輸出我是：

這應該工作。

- name: Create Ec2 Instances 
    hosts: localhost 
    connection: local 
    gather_facts: False 

    vars: 
    project_name: device-graph 
    ami_id: ami-59799439 # debian jessie 64-bit hvm

    zone: "us-west-2c" 
    instance_size: "t2.nano" 

    tasks: 
    - name: Provision a set of instances 
     ec2: 
     key_name: my_key 
     group: ["SSH only"] 
     instance_type: "{{ instance_size }}" 
     image: "{{ ami_id }}" 
     wait: true 
     exact_count: 1 
     count_tag:
