在Ansible中用模板模块追加文件

所以我有一个使用Jinja2模板创建日志文件的可靠剧本。每次我运行剧本时，它都会从customers.yml中提取客户信息，并将完成的模板输出到“stunnel.conf”文件中。该模板工作正常，但我试图找到一种方法来追加以前的'stunnel.conf'，而不是使用模板模块覆盖它。我希望手动添加文本到'stunnel.conf'的开头，而不是覆盖它。你认为这可能吗？在Ansible中用模板模块追加文件

Stunnel.conf

; GFAM - PBSTP 
[customer-GFAM-34074] 
cert = /etc/stunnel/stunnel.pem 
accept = 34094 
connect = 35094 

; GUANFABANK - FXSIM 
[customer-GUANFABANK-34051] 
cert = /etc/stunnel/stunnel.pem 
accept = 34095 
connect = 35095 

; ONEZERO2 - TRADESTREAM 
[customer-ONEZERO2-39124] 
cert = /etc/stunnel/stunnel.pem 
accept = 34096 
connect = 35096 

; BTG-VELOCITY - PBSTP 
[customer-BTG-VELOCITY-42533] 
cert = /etc/stunnel/stunnel.pem 
accept = 34097 
connect = 35097

Jinja2的模板

{#CONTEXT: {{ customers }}#} 
{% set currentport = 34093%} 
{% for cust, config in customers.items() %} 
; {{ cust }} - {{ config['type'] }} 
[customer-{{ cust }}-{{ config['accept'] }}] 
cert = {{ "/etc/stunnel/stunnel.pem" }} 
{#accept = {{ config['accept'] }}#} 
{#connect = {{ config['connect'] }}#} 
accept = {{ currentport + 1 }} 
connect = {{ currentport + 1001 }} 
{% set currentport = currentport + 1 %} 

{% endfor %}

playbook.yml

- include_vars: 
    file: /home/vagrant/stunnelSimAnsPractice/roles/ns16/vars/customers.yml 
    name: customers 

- template:

    dest: /home/vagrant/stunnelSimAnsPractice/roles/ns16/output/stunnel.conf 
    owner: root 
    group: root

我想建议做这样的：

将模板的输出保存到临时文件。
附加Stunnel.conf文件与临时文件的内容。
删除临时文件。

在剧本它可能看起来像：

- include_vars: 
    file: /home/vagrant/stunnelSimAnsPractice/roles/ns16/vars/customers.yml 
    name: customers 

- template: 
    src: /home/vagrant/stunnelSimAnsPractice/roles/ns16/templates/stunnel.j2 
    dest: /home/vagrant/stunnelSimAnsPractice/roles/ns16/output/temp.conf 
    owner: root 
    group: root 

- name: "Append stunnel.conf with content of temporary file" 
    shell: cat temp.conf >> stunnel.conf 
    args: 
    chdir: "/home/vagrant/stunnelSimAnsPractice/roles/ns16/output" 

- name: "Delete temporary file" 
    file: 
    path: /home/vagrant/stunnelSimAnsPractice/roles/ns16/output/temp.conf 
    state: absent

您可以使用blockinfile模块和template查找在你stunnel.conf来管理每个客户端的块：

- include_vars: 
    file: customers.yml 
    name: customers 

- blockinfile: 
    dest: stunnel.conf 
    block: "{{ lookup('template', 'stunnel.j2') }}" 
    marker: "; {mark} ANSIBLE MANAGED BLOCK FOR {{ cust }}"

我为了便于阅读，我们缩短了文件路径。

这种方式Ansible将为特定客户端（{{ cust }}变量）查找托管块并添加/替换模板化stunnel.j2中的内容。
