不幸的是,我得到了这个错误:
TASK [write unique number in myid]
*********************************************
fatal: [192.168.60.6]: FAILED! => {"failed": true, "msg": "The conditional check '{{item.value.ip}} == {{ ansible_all_ipv4_addresses[1] }}' failed.
The error was: error while evaluating conditional ({{item.value.ip}} == {{ ansible_all_ipv4_addresses[1] }}): float object has no element 60
The error appears to have been in '/home/shihhao/Desktop/BlueTech/ansible/kafka_playbook.yml': line 101, column 7,
but may be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:
- name: write unique number in myid
^ here\n"}
似乎一旦我添加这一行,我就会得到错误
when: "{{item.value.ip}} == {{ ansible_all_ipv4_addresses[1] }}"
顺便说一句:{{ansible\u all\u ipv4\u addresses[1]}是192.168.60.6您应该在
语句中使用裸变量:
when: item.value.ip == ansible_all_ipv4_addresses[1]
从:
在Ansible with the when子句中很容易做到这一点,它包含一个没有双花括号的原始Jinja2表达式
原始表达式在when:
语句中使用,带有assert
模块和debug:var=varname
(但是debug:msg=“{{{varname}}”
)。谢谢Konstantin。谢谢你,伙计,但是现在我很困惑在哪种情况下应该使用裸变量,在哪种情况下应该使用变量?”{{},你能给我一些建议吗?
