Ansible
shell/command 模組不提供來自樹莓派上 playbook 的輸出
使用 Ubuntu 的 Ansible 2.11.6。我有兩個樹莓派
inventory。一個是帶有 Stretch 的舊 Pi3；另一個是帶有 Buster 的 Pi4。$ ansible -i inventory -m shell -a "df -h" all
df -h正如預期的那樣，顯示了兩個 Pis的結果。但$ ansible-playbook -i inventory main.yml
main.yml在哪裡--- - hosts: all tasks: - name: show disk space shell: cmd: df -h收集事實後，展示
TASK [show disk space] ******************* changed: [pi4] changed: [pi3]沒有顯示的輸出
df -h。我試過
command:而不是shell:. 我試過了executable: /bin/bash。沒有不同。在建構 Ubuntu VM 時，同樣main.yml適用於 Vagrant ansible Provisioner，並顯示df -h輸出。我錯過了什麼？
更新這是我的錯誤。我一直使用的 Vagrantfile 模板包含
ansible.verbose = true. 刪除它，一切都會保持一致。
default預設情況下， stdout 回調不顯示任務結果。Ad hoc 命令通常使用minimal具有不同行為的回調。如果您在 Vagrant 輸出中看到它，它要麼使用不同的回調，要麼以更高的詳細程度執行，其中顯示了更多資訊：ec2-user@pandora ~ $ ansible-playbook test.yml PLAY [localhost] *************************************************************** TASK [command] ***************************************************************** changed: [localhost] PLAY RECAP ********************************************************************* localhost : ok=1 changed=1 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0ec2-user@pandora ~ $ ANSIBLE_STDOUT_CALLBACK=minimal ansible-playbook test.yml localhost | CHANGED | rc=0 >> Filesystem Size Used Avail Use% Mounted on devtmpfs 3.9G 0 3.9G 0% /dev tmpfs 3.9G 272K 3.9G 1% /dev/shm tmpfs 3.9G 8.9M 3.9G 1% /run tmpfs 3.9G 0 3.9G 0% /sys/fs/cgroup /dev/nvme0n1p1 12G 7.3G 4.8G 61% / /dev/nvme1n1 40G 9.0G 32G 23% /home fs-c2c955bb.efs.us-east-2.amazonaws.com:/ 8.0E 0 8.0E 0% /ammit tmpfs 788M 0 788M 0% /run/user/1913323 tmpfs 788M 0 788M 0% /run/user/257994 tmpfs 788M 0 788M 0% /run/user/1000ec2-user@pandora ~ $ ansible-playbook test.yml -vvv ansible-playbook [core 2.11.5] config file = /home/ec2-user/ansible-aws/ansible/ansible.cfg configured module search path = ['/home/ec2-user/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules'] ansible python module location = /home/ec2-user/ansible-aws/.venv/lib/python3.8/site-packages/ansible ansible collection location = /home/ec2-user/ansible-aws/ansible/collections executable location = /home/ec2-user/ansible-aws/.venv/bin/ansible-playbook python version = 3.8.5 (default, Feb 18 2021, 01:24:20) [GCC 7.3.1 20180712 (Red Hat 7.3.1-12)] jinja version = 3.0.2 libyaml = True Using /home/ec2-user/ansible-aws/ansible/ansible.cfg as config file Skipping callback 'default', as we already have a stdout callback.
