是否有办法将多个可见任务的结果/输出添加到ansible Controller节点上的同一文件? &g

Question

我需要将所有可见任务的输出存储到Ansible控制节点上的某个文件(在下面的示例中为output.log)中。。我试着用这种方式实现它。

- name: Playbook to store the output of two tasks to the same file
hosts: test
tasks:
- name: task_1
shell: command_1
register: output_1
- name: save output_1 using copy module
copy: 
content: {{ output_1.stdout_lines }}
dest: ./output.log
delegate_to: localhost
- name: task_2
shell: command_2
register: output_2
- name: save output_2 using copy module
copy: 
content: {{ output_2.stdout_lines }}
dest: ./output.log
delegate_to: localhost

问题是，当剧本完成执行时，output.log文件Has只有最后一个任务的输出。我知道每次我使用复制模块时，它都在替换旧的内容。

有没有办法做到这一点?

Answer 1

声明注册变量的模式

out_pattern: '^out_d+$'

执行任务并注册输出

- command: echo command_1
register: out_1
- command: echo command_2
register: out_2

获取所有注册变量的值并映射属性stdout_lines

- set_fact:
log: "{{ lookup('vars', *q('varnames', out_pattern))|
map(attribute='stdout_lines')|list }}"

为

log:
- [command_1]
- [command_2]

创建所有主机和变量的字典log

log_all: "{{ dict(ansible_play_hosts|
zip(ansible_play_hosts|
map('extract', hostvars, 'log'))) }}"

并将其写入控制器

上的文件中。

- copy:
dest: /tmp/out.log
content: "{{ log_all|to_yaml }}"
run_once: true
delegate_to: localhost

完整剧本示例

shell> cat pb.yml
- hosts: test
vars:
out_pattern: '^out_d+$'
log_all: "{{ dict(ansible_play_hosts|
zip(ansible_play_hosts|
map('extract', hostvars, 'log'))) }}"
tasks:
- command: echo command_1
register: out_1
- command: echo command_2
register: out_2
- set_fact:
log: "{{ lookup('vars', *q('varnames', out_pattern))|
map(attribute='stdout_lines')|list }}"
- debug:
var: log|to_yaml
- block:
- debug:
var: log_all|to_yaml
- copy:
dest: /tmp/out.log
content: "{{ log_all|to_yaml }}"
run_once: true
delegate_to: localhost

为

shell> ansible-playbook pb.yml -l test_11,test_13

日志文件

shell> cat /tmp/out.log 
test_11:
- [command_1]

test_13:

- [command_2]
