我使用ansible 2.1来rsync或将文件从主机复制到远程机器。该文件位于目录中,但随机字符串作为其名称的一部分。我尝试使用 ls -d 通过shell命令获取名称并尝试注册此值,但显然,我使用的语法导致该角色失败。关于我可能做错什么的任何想法?

- name: copying file to server
- local_action: shell cd /tmp/directory/my-server/target/
- local_action: shell ls -d myfile*.jar
register: test_build
- debug: msg={{ test_build.stdout }}
- copy: src=/tmp/directory/my-server/target/{{ test_build.stdout }} dest=/home/ubuntu/ owner=ubuntu group=ubuntu mode=644 backup=yes
become: true
become_user: ubuntu
become_method: sudo

如果可能,你应该避免shell
命令,它是Ansible反模式
在您的情况下,您可以使用fileglob
lookup,如下所示:
- name: Copy file
copy:
src: "{{ lookup('fileglob','/tmp/directory/my-server/target/myfile*.jar', wantlist=true) | first }}"
dest: /home/ubuntu/
owner: ubuntu
group: ubuntu
mode: 644
backup: yes
如果你100%确定只有一个这样的文件,你可以省略wantlist=true
和| first
- 我把它用作安全网,只过滤第一个条目,如果有很多。< / p>

您需要简化命令。您也不想在模块名称前加上连字符。这将导致语法错误,因为它无法将该模块识别为操作。您每个任务只能调用一个模块。例如,这不起作用;
- name: task one
copy: src=somefile dest=somefolder/
copy: src=somefile2 dest=somefolder2/
这两者需要分成两个单独的任务。你的剧本也一样。执行以下操作:
- name: copying file to server
local_action: "shell ls -d /tmp/directory/my-server/target/myfile*.jar"
register: test_build
- debug: msg={{ test_build.stdout }}
- name: copy the file
copy: src={{ test_build.stdout }} dest=/home/ubuntu/ owner=ubuntu group=ubuntu mode=644 backup=yes
如果可能,请插入&#34;成为&#34;在你的playbook中,而不是在你的tasks / main.yml文件中,除非你只想用于这两个任务,并且稍后会在同一个剧本中添加更多的任务。
注意:调试消息行完全是可选的。它不会以任何方式影响剧本的结果,它只会显示由于shell而导致的文件夹/文件名&#34; ls&#34;命令。
