Amazon web services 如何使用AWS实例&x27；在ansible playbook中动态设置IP地址，而不使用ansible playbook将其保存在外部文件中

我有两个集群，一个是卡桑德拉集群（4节点集群），另一个是卡夫卡集群（3节点集群）。我有一个在AWS实例上部署我的微服务的playbook，对于该微服务playbook，我维护了一个清单文件，该文件将我的cassandra/kafka主机的IP地址存储在一个变量中，如下所示：

cassandra_hosts = 'X.X.X.X:9042,X.X.X.X:9042,X.X.X.X:9042,X.X.X.X:9042'
kafka_host = 'X.X.X.X:9092,X.X.X.X:9092,X.X.X.X:9092,X.X.X.X:9092'

- hosts: dynamic_hosts
  become: yes
  become_user: xxxxxx
  become_method: sudo 

  vars:
   ansible_connection: "{{ connection_type }}"
   ansible_ssh_user: "{{ ssh_user_name }}"
   ansible_ssh_private_key_file: "{{ ssh_private_key_file }}"

  tasks:

    - name: Register Service as an Upstart
      shell: chdir="{{dest_location}}" "./{{upstartscript}}.sh" " -p  {{service_port}}  -u  {{service_uri}}  -v  {{service_version}}  -c  {{cassandra_hosts}}  -k  {{kafka_host}}  -l  {{log_level}}"
      register: escript

    - name: Register Service as an Upstart Output
      debug: 
       msg : "{{ escript.stdout }}"

上面的代码是我检索我在清单文件中硬编码的IP地址的方式（在代码的第一部分中提到）

我试图实现的是，如何在playbook中动态存储AWS实例的IP地址，并在microservices playbook中使用它，而不将IP地址存储在清单文件中，有什么建议吗

另外，如果需要的话，我请求你提出任何问题，这是我在这里的第一个问题，提前谢谢

嗨， 我还需要获取kafka集群的输出，但是kafka集群在AWS控制台中以不同的方式输出它，如下所示：

cassandra_hosts = 'X.X.X.X:9042,X.X.X.X:9042,X.X.X.X:9042,X.X.X.X:9042'
kafka_host = 'X.X.X.X:9092,X.X.X.X:9092,X.X.X.X:9092,X.X.X.X:9092'

- hosts: dynamic_hosts
  become: yes
  become_user: xxxxxx
  become_method: sudo 

  vars:
   ansible_connection: "{{ connection_type }}"
   ansible_ssh_user: "{{ ssh_user_name }}"
   ansible_ssh_private_key_file: "{{ ssh_private_key_file }}"

  tasks:

    - name: Register Service as an Upstart
      shell: chdir="{{dest_location}}" "./{{upstartscript}}.sh" " -p  {{service_port}}  -u  {{service_uri}}  -v  {{service_version}}  -c  {{cassandra_hosts}}  -k  {{kafka_host}}  -l  {{log_level}}"
      register: escript

    - name: Register Service as an Upstart Output
      debug: 
       msg : "{{ escript.stdout }}"

我只想输出卡夫卡林克角色的IP，有什么帮助吗：

    X.X.X.X:9092,X.X.X.X:9092,X.X.X.X:9092,X.X.X.X:9092

我尝试了以下命令，但它不起作用：

 aws cloudformation describe-stacks --stack-name IngKafkaCluster --query 'Stacks[].Outputs[].OutputValue' --output text

我在上面的命令上得到以下输出，这没有错，但不完全是我想要的：

X.X.X.X:2181,X.X.X.X:2181,X.X.X.X:2181,X.X.X.X:2181        ip-X-X-X-X.ec2.internal    X.X.X.X:9092,X.X.X.X:9092,X.X.X.X:9092,X.X.X.X:9092        ip-X-X-X-X.ec2.internal   ip-X-X-X-X.ec2.internal   ip-X-X-X-X.ec2.internal

要获取AWS EC2的Ip地址，您可以尝试以下命令，该命令将AWS输出提取到所需的文件中：

 aws cloudformation describe-stacks --stack-name IngCassandraCluster --query 'Stacks[].Outputs[].OutputValue' --output text --> kunaltest.text

---

您可以在playbook中的以下位置添加这一行：shell:“让它做您想做的事。

你可以在剧本中添加以下内容：shell：“让它做你想做的事。
