关于 `jq` 命令的详细解释及安装教程：https://wangchujiang.com/linux-command/c/jq.html

---

语法：
```shell
docker inspect <container ID> | jq '.[0].Mounts'
```

例如：
```shell
shine@Shine-Win11:~/documents/self-projects/tmp$ docker inspect aa3f359ddc0e | jq '.[0].Mounts'
[
  {
    "Type": "bind",
    "Source": "/home/shine/documents/git/projects/docker-elk/elasticsearch/config/elasticsearch.yml",
    "Destination": "/usr/share/elasticsearch/config/elasticsearch.yml",
    "Mode": "ro,Z",
    "RW": false,
    "Propagation": "rprivate"
  },
  {
    "Type": "volume",
    "Name": "docker-elk_elasticsearch",
    "Source": "/var/lib/docker/volumes/docker-elk_elasticsearch/_data",
    "Destination": "/usr/share/elasticsearch/data",
    "Driver": "local",
    "Mode": "z",
    "RW": true,
    "Propagation": ""
  }
]
```

## 查看 docker-compose.yaml 路径

语法：
```shell
docker inspect <container ID> | jq '.[0].Config.Labels'
```

示例：
```shell
shine@Shine-Win11:~/documents/git/projects/docker-elk$ docker inspect 8334b593b89a | jq '.[0].Config.Labels'
{
  "com.docker.compose.config-hash": "d1f80fc712ff55f9f33eafc4842bf71f947a6584b27eb548bca0c0dc399bff8b",

composer 永久忽略安装包时提示依赖 xx 扩展

## 问题

在本地开发时，如果使用 composer 安装 composer 包经常会遇到这种提示：
```
Your requirements could not be resolved to an installable set of packages.

Problem 1
    - Root composer.json requires php ^8.3 but your php version (8.2.9) does not satisfy that requirement.
  Problem 2
    - Root composer.json requires PHP extension ext-posix * but it is missing from your system. Install or enable PHP's posix extension.
  Problem 3
    - Root composer.json requires PHP extension ext-rdkafka * but it is missing from your system. Install or enable PHP's rdkafka extension.
  Problem 4
    - hhxsv5/laravel-s is locked to version v3.8.0 and an update of this package was not requested.
    - hhxsv5/laravel-s v3.8.0 requires ext-pcntl * -> it is missing from your system. Install or enable PHP's pcntl extension.
  Problem 5
    - laravel/horizon is locked to version v5.24.4 and an update of this package was not requested.
    - laravel/horizon v5.24.4 requires ext-pcntl * -> it is missing from your system. Install or enable PHP's pcntl extension.
  Problem 6
    - laravel/pail is locked to version v1.1.3 and an update of this package was not requested.
    - laravel/pail v1.1.3 requires ext-pcntl * -> it is missing from your system. Install or enable PHP's pcntl extension.

To enable extensions, verify that they are enabled in your .ini files:
    - C:\Users\Shine\.pvm\versions\php-8.2\php.ini
You can also run `php --ini` in a terminal to see which files are used by PHP in CLI mode.
Alternatively, you can run Composer with `--ignore-platform-req=ext-posix --ignore-platform-req=ext-rdkafka --ignore-platform-req=ext-pcntl` to temporarily ignore these required extensions.
You can also try re-running composer require with an explicit version constraint, e.g. "composer require dcat/laravel-admin:*" to figure out if any version is installable, or "composer require dcat/laravel-admin:^2.1" if you know which you need.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.
```

实际上在本机开发过程中通常不需要用到这些依赖扩展，或者你是 Windows 作为开发环境，那么像 `posix`, `pcntl` 扩展在 Windows 上是安装不上的，所以我都会加上 `--ignore-platform-reqs` 选项，来跳过对这些扩展的检查，但是每次装 composer 包都要手打这个选项实在是太过繁琐，有没有直接替我加上这个选项的方法？

## 过程

通过查阅[Composer 官方文档](https://getcomposer.org/doc/03-cli.md#composer-ignore-platform-req-or-composer-ignore-platform-reqs "Composer 官方文档")，确实有这么一个方法，设置一个环境变量 `COMPOSER_IGNORE_PLATFORM_REQS=1` 即可解决

## 结果

Windows 添加环境变量

1. 按下 `Win` + `R` 输入 `sysdm.cpl` 然后按 `Enter`
2. 选择“环境变量”
3. 新建环境变量
4. 输入变量名 `COMPOSER_IGNORE_PLATFORM_REQS`
5. 输入变量值 `1`
6. 确定 -> 确定 -> 确定
7. 完成
