我的ansible脚本所在的目录中有一个json文件。以下是json文件的内容:
{ "resources":[
{"name":"package1", "downloadURL":"path-to-file1" },
{"name":"package2", "downloadURL": "path-to-file2"}
]
}
我正在尝试使用get_url下载这些软件包。以下是方法:
---
- hosts: localhost
vars:
package_dir: "/var/opt/"
version_file: "{{lookup('file','/home/shasha/devOps/tests/packageFile.json')}}"
tasks:
- name: Printing the file.
debug: msg="{{version_file}}"
- name: Downloading the packages.
get_url: url="{{item.downloadURL}}" dest="{{package_dir}}" mode=0777
with_items: version_file.resources
第一项任务是正确打印文件内容,但在第二项任务中,我收到以下错误:
[DEPRECATION WARNING]: Skipping task due to undefined attribute, in the future this
will be a fatal error.. This feature will be removed in a future release. Deprecation
warnings can be disabled by setting deprecation_warnings=False in ansible.cfg.

您必须在查找后添加from_json
jinja2过滤器:
version_file: "{{ lookup('file','/home/shasha/devOps/tests/packageFile.json') | from_json }}"

如果您需要阅读JSON
格式的文本并将其存储为变量,则include_vars
也可以处理它。
- hosts: localhost
tasks:
- include_vars:
file: variable-file.json
name: variable
- debug: var=variable

对于将来的访问者,如果您正在寻找读取的远程json文件。这行不通 因为ansible查找是在本地执行的
您应该使用类似Slurp
的模块
