我構建了以下列表,但我沒有成功迭代它。 我應該使用with_items嗎? with_elements?或者是其他東西?Ansible - 遍歷字典列表
我的目標是迭代庫存中的所有主機,獲取其名稱和IP,最後打印出來。
- set_fact:
list_of_hosts: |
{% set myList = [] %}
{% for host in groups['all'] %}
{% set ignored = myList.extend([{'server_name': host, 'server_ip': hostvars[host].ansible_eth0.ipv4.address }]) %}
{% endfor %}
{{ myList }}
- debug: msg="{{ item.server_name }}"
with_items: "{{ list_of_hosts }}"
這是我名單時,我調試它:
TASK [common : debug] ************************************************************************************************
ok: [my1stServer] => {
"msg": " [{'server_ip': u'192.168.0.1', 'server_name': u'my1stServer'}, {'server_ip': u'192.168.0.2', 'server_name': u'my2ndServer'}]\n"
}
這裏是錯誤,但它不是真正相關:
fatal: [my1stServer]: FAILED! => {"failed": true, "msg": "the field 'args' has an invalid value, which appears to include a variable that is undefined. The error was: 'ansible.vars.unsafe_proxy.AnsibleUnsafeText object' has no attribute 'server_name'\n\nThe error appears to have been in 'hosts.yml': line 19, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n- debug: msg=\"{{ item.server_name }}\"\n^here\nWe could be wrong, but this one looks like it might be an issue with\nmissing quotes. Always quote template expression brackets when they\nstart a value. For instance:\n\n with_items:\n - {{ foo }}\n\nShould be written as:\n\n with_items:\n - \"{{ foo }}\"\n"}
另外,您更好地使用'ansible_default_ipv4.address'。 –
