    "datarow1":{  
        "Club":[  
            {  
                "club.name":"FC Bar"

            {

                ]
            }
        ]
    }, 
    "datarow2":{  
        "Club":[  
            {  
                "club.name":"FC TU"
            },

                ]
            },
            {  
                "participation":[  
                    {  
                        "participation.league":[

                        ]
                    }
                ]
            }
        ]
    }, 

}

但是在{= <...

中没有看到- name: Ensure IP or domain is a known host lineinfile: > dest={{ home }}/.ssh/known_hosts create=yes state=present line="{{ lookup('pipe', 'ssh-keyscan -t ecdsa {{ item }}') }}" with_items: - 88.48.189.102 - my.site.com

我明白了：

{{item}}

Answer 1

你不需要内花括号。您只需以这种方式将项连接为字符串：

{{ lookup('pipe', 'ssh-keyscan -t ecdsa ' ~ item) }}

或

{{ lookup('pipe', 'ssh-keyscan -t ecdsa ' + item) }}

但是jinja docs说第一个是首选方法。
