使用Terraform代码，我在AWS Secrets Manager中创建了Other type of secrets。我需要在Ansible代码中使用这些AWS秘密。我在下面找到了这个链接，但我无法继续。

https://docs.ansible.com/ansible/2.8/plugins/lookup/aws_secret.html

我有下面的Ansible代码：

database.yml

- name: Airflow | DB | Create MySQL DB
  mysql_db:
    login_user: "{{ mysql_user }}"
#    login_password: "{{ mysql_root_password }}"
    login_password: "{{ lookup('ca_dev', 'mysql_root_password') }}"
#    config_file: /etc/my.cnf
#    login_unix_socket: /var/lib/mysql/mysql.sock
#    encrypted: yes
    name: "airflow"
    state: "present"

如何在我的ansible代码中加入AWS secret Manager？

错误消息：-

错误{"msg": "lookup plugin (ca_dev) not found"}表明您的问题是误用了lookup命令。

下面这行代码：

login_password: "{{ lookup('ca_dev', 'mysql_root_password') }}"

应该看起来像这样

login_password: "{{ lookup('aws_secret', 'mysql_root_password') }}"

ca_dev不是有效的查找类型，而aws_secret是。

你可以在官方文档的Lookup Plugins部分看到Ansible 2.8支持的查找插件的列表。

如果您正在使用自定义查找插件，或者将插件从ansible的未来版本反向移植到旧版本，则必须确保它位于ansible可见的目录中。

您可以将自定义文件放置在~/.ansible/plugins/lookup:/usr/share/ansible/plugins/lookup中的默认位置，也可以使用以下lookup_plugins ini键在defaults部分下配置ansible.cfg以在不同的位置进行查找。

DEFAULT_LOOKUP_PLUGIN_PATH
Description:    Colon separated paths in which Ansible will search for Lookup Plugins.
Type:   pathspec
Default:    ~/.ansible/plugins/lookup:/usr/share/ansible/plugins/lookup
Ini Section:    defaults
Ini Key:    lookup_plugins
Environment:    ANSIBLE_LOOKUP_PLUGINS
