背景:
我有一个包含两个角色的项目。
为了便于理解,我将任务数量缩减为问题任务。
问题:
我从 server1 中的角色 1 运行一个任务,并尝试根据第一个 server1 角色任务中的条件将任务委托给 vmware 虚拟化器。由于主机想要执行 server1 中的第二个角色任务 (Vmware),因此主机出现故障。
错误:
fatal: [testhost]: FAILED! => {"reason": "conflicting action statements: hosts,
gather_facts\n\nThe error appears to be in '/home/ancible/proyects/extend_fs-role/roles/vmwaretaks/tasks/addvmwaredisk.yml': line 2, column 3,
but may\nbe elsewhere in the file depending on tntax problem.\n\nThe offending line appears to be:\n\n---\n- hosts: localhost\n ^ here\n"}
结构如下:

如果主机中没有找到可用的LUN,则执行顺序如下:
resizefs_role_hosts.yml -> roles/resizefs/tasks/main.yml -> roles/resizefs/tasks/findfreedisk.yml -> \
roles/vmwaretaks/tasks/main.yml -> roles/vmwaretaks/tasks/addvmwaredisk.yml
剧本如下:
$ cat resizefs_role_hosts.yml
---
- hosts: testhost
become: yes
become_method: sudo
roles:
- role: 'roles/resizefs'
$ cat roles/resizefs/tasks/main.yml
---
# tasks file for create_fs-test
- import_tasks: findfreedisk.yml
$ cat roles/resizefs/tasks/findfreedisk.yml
- name: Finding disk with no partitions
set_fact:
disks: "/dev/{{outer_item.key}}"
when:
- not outer_item.value.partitions
- not outer_item.value.links.ids
- outer_item.key is search ("sd")
with_dict: '{{ansible_devices}}'
loop_control:
loop_var: outer_item
notify:
- Format_free_disk
changed_when: true
- name: Print disk name if available
debug:
msg:

# If not disk available add new lun from Vmware
- include_role:

when: disks is undefined
$ cat roles/vmwaretaks/tasks/main.yml

# tasks file for add-new-vmware-lun

vcenter_password: "{{ vault_pass }}"
target_host: 'TESTHOST'
vm_uuid: '4217B33E-014D-E056-0719-45AD3AC1861E'
vm_unit_number: '5'
tasks:
- name: Add disks to virtual machine using UUID
vmware_guest_disk:
hostname: "{{ vcenter_hostname }}"
username: "{{ vcenter_username }}"
password: "{{ vcenter_password }}"
datacenter: "{{ vcenter_hostname }}"
uuid: "{{ vm_uuid | lower }}"
validate_certs: no
disk:
- size_gb: 10
type: 'thick'
state: 'present'
autoselect_datastore: yes
scsi_controller: '0'
scsi_type: 'paravirtual'
unit_number: '5'
disk_mode: 'independent_persistent'
delegate_to: localhost
我试图找到一种方法来告诉它第二个角色不是在服务器中执行,而是在 vmware 虚拟化器中执行,但没有成功。
如果我将 addvmwaredisk.yml 作为剧本运行,它会完美运行
希望你能帮忙!
提前谢谢!

hosts
和tasks
是播放关键字,它们不能在任务列表中使用。要在当前播放主机以外的其他主机上执行任务,请使用代表团;要将相关任务分组并对所有任务应用指令,请使用堵塞。
- delegate_to: localhost
vars:
vcenter_hostname: 'vcenter.labo.local'
vcenter_username: 'labo.local\ansible'
vcenter_password: "{{ vault_pass }}"
target_host: 'TESTHOST'
vm_uuid: '4217B33E-014D-E056-0719-45AD3AC1861E'
vm_unit_number: '5'
block:
- name: Add disks to virtual machine using UUID
vmware_guest_disk:
hostname: "{{ vcenter_hostname }}"
username: "{{ vcenter_username }}"
password: "{{ vcenter_password }}"
datacenter: "{{ vcenter_hostname }}"
uuid: "{{ vm_uuid | lower }}"
validate_certs: no
disk:
- size_gb: 10
type: 'thick'
state: 'present'
autoselect_datastore: yes
scsi_controller: '0'
scsi_type: 'paravirtual'
unit_number: '5'
disk_mode: 'independent_persistent'

好吧,我最近解决了这个问题,只是添加了变成:否
- delegate_to: localhost
become: no
delegate_facts: yes
