# The setup command allows filtering facts
# More info: https://docs.ansible.com/ansible/latest/modules/setup_module.html
# inventory_file = path to inventory file (if not normal role layout)
# host_group = group to query. use all for all hosts
ansible -i inventory_file host_group -m setup -a 'filter=ansible_distribution_version'

# For a Ubuntu Bionic Host the distribution facts look like this:
#        "ansible_distribution": "Ubuntu", 
#        "ansible_distribution_file_parsed": true, 
#        "ansible_distribution_file_path": "/etc/os-release",

# 概述：一共三大部分配置。
# 其中#注释掉的可以在需要的时候开启并修改，没有注释掉的（除了下面location示例）不要删掉，基本都是必须的配置项。

###############################第一部分 全局配置############################
#user  nobody;                        指定启动进程的用户，默认不用指定即可。
#error_log  logs/error.log;           配置日志输出，虽然叫error_log但是可以定义输出的级别，默认不写是ERROR级别
#error_log  logs/error.log  notice;   
#error_log  logs/error.log  info;
#pid        logs/nginx.pid;           记录pid的文件，默认就是放到这个位置，可以修改。

How to reduce size of docker data volume in Docker Desktop for Windows v2

Docker Desktop for Windows v2, which uses WSL2, stores all image and container files in a separate virtual volume (vhdx). This virtual hard disk file can automatically grow when it needs more space (to a certain limit). Unfortunately, if you reclaim some space, i.e. by removing unused images, vhdx doesn't shrink automatically.

Optimize

wsl --shutdown
Optimize-VHD -Path "$($env:LOCALAPPDATA)\Docker\wsl\data\ext4.vhdx" -Mode Full
