My base template contains this code (edited for simplicity): <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> {% from "foo.html" import macro1, macro2, macro3 %} {%

ansible filter with json_query

爷,独闯天下 提交于 2019-12-12 05:28:50
问题 I write this: - name: test for seed debug: var: hostvars|json_query("*.ansible_host") And it prints every host.
