库存如下:

{{/* vim: set filetype=mustache: */}}
{{/*
Expand the name of the chart.
*/}}
{{- define "unleash.name" -}}
{{- default .Chart.Name .Values.nameOverride | trunc 63 | trimSuffix "-" -}}
{{- end -}}
{{/*
Create a default fully qualified app name.
We truncate at 63 chars because some K8S name fields are limited to this (by the DNS naming spec).
*/}}
{{- define "unleash.fullname" -}}
{{- if .Values.fullnameOverride -}}
{{- .Values.fullnameOverride | trunc 26 | trimSuffix "-" -}}
{{- else -}}
{{- $name := default .Chart.Name .Values.nameOverride -}}
{{- printf "%s-%s" .Release.Name $name | trunc 63 | trimSuffix "-" -}}
{{- end -}}

我想 在模板中使用ansible_host哦'h2' ,但是我遇到了 ansible.errors.AnsibleUndefinedVariable 错误。如何解决?

我已经尝试过这些:

[host-1]
h1    ansible_ssh_private_key_file="*/*/*"    ansible_host=a.b.c.d
h2    ansible_ssh_private_key_file="*/*/*"    ansible_host=a.b.c.t

[host-2]
h3    ansible_ssh_private_key_file="*/*/*"    ansible_host=a.b.c.r

请提示:

- name: host
  debug: msg="{{hostvars['h2']['ansible_host']}}"

正确的语法

"{{ hostvars['h2']['ansible_host'] }}"

"{{ hostvars.h2.ansible_host }}"

提示:看看"{{ hostvars }}""{{ groups }}"
