示例:
- name: Check the count of numberServers matches that of jvm variables
assert:
that: item|count|int == numberServers
msg: JVM count for {{item}} doesn't match numberServers
with_items:
- "{{ JVMs_ }}"
- "{{ jvmName }}"
- "{{ jvmSize }}"
- "{{ jvmHeap }}"
所以说JVMs_
没有定义,我希望任务能够为剩下的项目运行。
* 注意:已尝试使用when
;如果不满足条件,它会跳过整个任务。
此外,创建单独的任务不是一个好选择,因为我有超过4个项目要循环。

在您的情况下,您可以使用|default([])
,with_items
忽略空列表:
- name: Check the count of numberServers matches that of jvm variables
assert:
that: item|count|int == numberServers
msg: JVM count for {{item}} doesn't match numberServers
with_items:
- "{{ JVMs_ | default([]) }}"
- "{{ jvmName | default([]) }}"
- "{{ jvmSize | default([]) }}"
- "{{ jvmHeap | default([]) }}"
