我有一个文本文件，看起来像这样:
hints_directory: /opt/cassandra/hints
data_file_directory: /opt/cassandra/data,/opt/cassandra/data2
commitlog_directory: /opt/cassandra/commitlog
cdc_raw_directory: /opt/cassandra/cdc_raw
saved_caches_directory: /opt/cassandra/saved_caches
tmp_directory: /opt/cassandra/tmp
jna_directory: /opt/cassandra/jna
dump_directory: /opt/cassandra/dump
我想读取该文件，并使用ansible检查每个目录是否存在。棘手的部分出现在第二行，这一行包含两个目录路径。我怎样才能像下面的例子那样读取文件的每一行，并检查每个目录是否存在呢?
这是我到目前为止所得到的，但是由于单行有多个路径值，它在data_file_目录上出错了。我试过拆分行条目，但这不能解决问题。
想法吗?
- name: Ensure the directories exist
file:
path: "{{item.split(':')[1].split(' ')[1].split(',')}}"
state: directory
with_lines: cat <<pathtofile>>/directories.txt
将文件中的变量读入字典并将字符串转换为列表，例如
- include_vars:
file: directories.txt
name: dirs_str
- set_fact:
dirs_list: "{{ dict(_keys|zip(_vals)) }}"
vars:
_keys: "{{ dirs_str.keys()|list }}"
_vals: "{{ dirs_str.values()|map('split', ',')|list }}"
为
dirs_list:
cdc_raw_directory:
- /opt/cassandra/cdc_raw
commitlog_directory:
- /opt/cassandra/commitlog
data_file_directory:
- /opt/cassandra/data
- /opt/cassandra/data2
dump_directory:
- /opt/cassandra/dump
hints_directory:
- /opt/cassandra/hints
jna_directory:
- /opt/cassandra/jna
saved_caches_directory:
- /opt/cassandra/saved_caches
tmp_directory:
- /opt/cassandra/tmp
选择并平坦化值，例如
- set_fact:
allDirectories: "{{ dirs_list.values()|flatten }}"
为
allDirectories:
- /opt/cassandra/hints
- /opt/cassandra/data
- /opt/cassandra/data2
- /opt/cassandra/commitlog
- /opt/cassandra/cdc_raw
- /opt/cassandra/saved_caches
- /opt/cassandra/tmp
- /opt/cassandra/jna
- /opt/cassandra/dump
，或者直接在循环
中使用表达式- name: Ensure the directories exist
file:
path: "{{ item }}"
state: directory
loop: "{{ dirs_list.values()|flatten }}"
对于其他可能有类似练习的人，我已经想出了如何做到这一点:
- set_fact:
allDirectories: []
- set_fact:
allDirectories: "{{ item.split(':')[1].split(' ')[1].split(',') + allDirectories}}"
with_lines: cat <<pathtofile>>/directories.txt
- name: Ensure the directories exist
file:
path: "{{item}}"
state: directory
with_items: "{{allDirectories}}"
