Ansible

Question

我是 Ansible 的新手，我正在尝试检查我的 Ansible 控制机器中是否存在文件（至少应该有一个），如果存在，请复制到远程位置。

我想出了以下方法，但 ansible 正在检查远程而不是本地中的文件。我不太确定 - 如何使用 "with_items"。

---
- hosts: linux
  gather_facts: no
  vars:
   source_dir: /login/my_home
   server_type: WRITEVIEW
   files:
      - app.xslt
      - Configuration.xml
      - fcCN.xslt

  tasks:
   - name: Validate if file exists
     local_action: file path="{{ source_dir }}/{{ item }}" state=file
     with_items: files

错误信息：

TASK [Validate if file exists] ****************************************************************************************************************************************** failed: [remoteserver_1 -> localhost] (item=files) => {"changed": false, "item": "files", "msg": "file (/login/my_home/files) is absent, cannot continue", "path": "/login/my_home/files", "state": "absent"} failed: [remoteserver_2 -> localhost] (item=files) => {"changed": false, "item": "files", "msg": "file (/login/my_home/files) is absent, cannot continue", "path": "/login/my_home/files", "state": "absent"}

您可以使用stat命令来检查文件是否存在。如果存在，那么copy它到远程服务器：

---
- hosts: linux
  gather_facts: no
  vars:
   source_dir: /login/my_home
   server_type: WRITEVIEW
   files:
      - app.xslt
      - Configuration.xml
      - fcCN.xslt

   tasks:
    - name: check if file exists
      local_action: stat path=/path/of/file/{{ item }}
      with_items: "{{ files }}"
      register: check_file_name

    - name: Verifying if file exists
      debug: msg="File {{ item.item }} exist"
      with_items: "{{ check_file_name.results }}"
      when: item.stat.exists

    - name: Copying the file
      copy: src=/path/of/file/local/{{ item.item }} dest=/path/of/file/remote/
      with_items: "{{ check_file_name.results }}"
      when: item.stat.exists

Ansible - 检查本地是否存在多个文件并复制到远程

Ansible - Check if multiple files exists locally and copy to remote
