我有一个问题是使用ansible解析json 我有一个连接到牧场主的任务并获得一个json文件
任务:
- uri:
url: http://rancher.local:8080/v1/hosts
method: GET
user: ##################
password: ################
body_format: json
register: hosts_json
- name: test
set_fact:
rancher_env_hosts: "{{ item.hostname }}"
#when: item.hostname == "*-i-*"
with_items: "{{hosts_json.json.data}}"
- name: output
debug:
msg: "hosts: {{rancher_env_hosts}}"
我得到以下json(编辑后更易读):
{
"json": {
"data": [
{
"hostname": "rancher-i-host-02",
"id": "adsfsa"
},
{
"hostname": "rancher-i-host-01",
"id": "gfdgfdg"
},
{
"hostname": "rancher-q-host-01",
"id": "dfgdg"
},
{
"hostname": "rancher-q-host-02",
"id": "dfgdg"
}
]
}
}
当我启动playbook时,我只得到变量中的最后一个主机名,而不是主机名列表。我可以将所有列表注册到同一个变量吗?
此外,我还添加了一行注释“#”,以便只获取与字符串“-i-”匹配的主机名,它不起作用。任何想法?

试试这个
- uri:
url: http://rancher.local:8080/v1/hosts
method: GET
user: ##################
password: ################
body_format: json
register: hosts_json
- name: init fact
set_fact:
rancher_env_hosts: "[]"
- name: test
set_fact:
rancher_env_hosts: "{{rancher_env_hosts}} + [ {{item.hostname}} ]"
when: item.hostname | search(".*-i-.*")
with_items: "{{hosts_json.json.data}}"
- name: output
debug:
msg: "hosts: {{rancher_env_hosts}}"
关于search
,您可以在此处阅读http://docs.ansible.com/ansible/playbooks_tests.html
UPD:
关于在此处向数组添加值:Is it possible to set a fact of an array in Ansible?
答案 1 :(得分:3)
NATS.stop
NATS.start do
...do your messaging...
NATS.flush # Ensure processing of pending messages
NATS.stop # Immidiate exit
end
将包含所有主机名,- set_fact:
hosts_all: "{{ hosts_json.json.data | map(attribute='hostname') | list }}"
hosts_i: "{{ hosts_json.json.data | map(attribute='hostname') | map('regex_search','.*-i-.*') | select('string') | list }}"
将仅包含host_all
个匹配的主机名。
