当我使用
--tags
来过滤要执行的任务时,我习惯使用 ansible-playbook
。
我最近从 Ansible 2.7 切换到 2.9(差距很大,嗯?)。
令我惊讶的是,当我使用
--tags
时,ansible 并没有专门收集事实。我在 GitHub 上看到了多个类似的案例,例如“这个”或“这个”。它似乎从 2.8 版本开始影响 ansible,但显示为已解决。有人可以证实这种行为吗?好像是从2.8开始的。
ANSIBLE 版本 :
ansible --version
ansible 2.9.9.post0
config file = None
configured module search path = [u'/opt/ansible/ansible/library']
ansible python module location = /opt/ansible/ansible/lib/ansible
executable location = /opt/ansible/ansible/bin/ansible
python version = 2.7.6 (default, Nov 13 2018, 12:45:42) [GCC 4.8.4]
:
ansible-config dump --only-changed
DEFAULT_MODULE_PATH(env: ANSIBLE_LIBRARY) = [u'/opt/ansible/ansible/library']
:
剧本测试.yml:
- name: First test
hosts: localhost
connection: local
gather_facts: yes
roles:
- { role: test, tags: test }
tags: first
- name: Second test
hosts: localhost
connection: local
gather_facts: yes
roles:
- { role: test, tags: test }
tags: second
角色:角色/测试/任务/main.yml
- debug:
msg: System {{ inventory_hostname }} has uuid {{ ansible_product_uuid }}
结果:
ansible-playbook test.yml --check
= 没有错误。ansible-playbook test.yml --check --tags "test"
= 失败:1
我可以在输出中看到事实没有被收集。
嗯,当你在游戏关卡上有标签时,这似乎是一种有目的的行为:
gather_facts
,这与角色的使用无关,因为它可以通过简单地执行以下操作来重现:always
标签。如果目标是为该剧添加标签,您可以添加带有标签的
任务以收集事实。 samdoransetup
- name: First test
hosts: all
tags:
- first
tasks:
- debug:
msg: System {{ inventory_hostname }} has uuid {{ ansible_product_uuid }}
tags: test
这导致了失败的回顾:
$ ANSIBLE_STDOUT_CALLBACK=debug ansible-playbook play.yml --tags "test"
PLAY [First test] *************************************************************************************************
TASK [debug] ******************************************************************************************************
fatal: [localhost]: FAILED! => {}
MSG:
The task includes an option with an undefined variable. The error was: 'ansible_product_uuid' is undefined
The error appears to be in '/ansible/play.yml': line 7, column 7, but may
be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:
tasks:
- debug:
^ here
PLAY RECAP ********************************************************************************************************
localhost : ok=0 changed=0 unreachable=0 failed=1 skipped=0 rescued=0 ignored=0
因此,您要么必须删除您的游戏级别的标签,要么按照提示使用
setup
模块。这可以在您的角色内部完成,因此您的角色不再依赖于可能无法设置的变量。
鉴于角色roles/test/tasks/main.yml- setup:
- debug:
msg: System {{ inventory_hostname }} has uuid {{ ansible_product_uuid }}
还有剧本:
- name: First test
hosts: all
tags:
- first
roles:
- role: test
tags:
- test
- name: Second test
hosts: all
tags:
- second
roles:
- role: test
tags:
- test
以下是运行和回顾:
$ ansible-playbook play.yml --tags "test"
PLAY [First test] *************************************************************************************************
TASK [test : setup] ***********************************************************************************************
ok: [localhost]
TASK [test : debug] ***********************************************************************************************
ok: [localhost] => {
"msg": "System localhost has uuid 3fc44bc9-0000-0000-b25d-bf9e26ce0762"
}
PLAY [Second test] ************************************************************************************************
TASK [test : setup] ***********************************************************************************************
ok: [localhost]
TASK [test : debug] ***********************************************************************************************
ok: [localhost] => {
"msg": "System localhost has uuid 3fc44bc9-0000-0000-b25d-bf9e26ce0762"
}
PLAY RECAP ********************************************************************************************************
localhost : ok=4 changed=0 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0
这一切都运行于:
ansible 2.9.9
config file = None
configured module search path = ['/root/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
ansible python module location = /usr/lib/python3.8/site-packages/ansible
executable location = /usr/bin/ansible
python version = 3.8.3 (default, May 15 2020, 01:53:50) [GCC 9.3.0]
将
