命令:
inspect:
查看容器配置信息等
# 上面命令会输入一个 pretty json 外面都是 container 的信息
$ docker inspect <container name/container id> 查看具体某一个配置
# key1 belong to value0 of key0 and key2 belong to value1 of key1 and so on
$ docker inspect -f='{{.<key0>[.<key1>][.key2][...]}}' <container name/container id>
# or
$ docker inspect --format='{{.<key0>[.<key1>][.key2][...]}}' <container name/container id>
# example:
# docker inspect -f='{{.NetworkSettings}}' nginx
# output:
# {{0f3f569dce91a16751c170f91ef9c8c128c757f86dff4e39f8ab58ae686f4edb false 0 map[80/tcp:[{0.0.0.0 9002} {:: 9002}]] /var/run/docker/netns/0f3f569dce91 [] []} {553e63fa029a7dc7e123c74b330830033fdcc2a409baae5745e3875d17d6d580 172.17.0.1 0 172.17.0.3 16 02:42:ac:11:00:03} map[bridge:0xc0003f0000]} 格式化输入，上门的 -f 参数输入的数据格式，都是 value, 尽管排序是按程序的，然而咱们不晓得 value 具体对应那个 key.
# 上面命令输入的是 json 格局的数据
$ docker inspect -f '{{json .NetworkSettings.Networks}}' nginx
# 留神：# 正确示例：# docker inspect -f '{{json .NetworkSettings.Networks}}' nginx -- √
# docker inspect -f='{{json .NetworkSettings.Networks}}' nginx -- √
# docker inspect --format='{{json .NetworkSettings.Networks}}' nginx -- √
# docker inspect --format '{{json .NetworkSettings.Networks}}' nginx -- √
# 下面四个都是相等的，然而不要写成上面的
# 谬误示例:
# docker inspect -f 'json {{.NetworkSettings.Networks}}' nginx -- ×
# Output Example: {"Bridge":"","SandboxID":"0f3f569dce91a16751c170f91ef9c8c128c757f86dff4e39f8ab58ae686f4edb","HairpinMode":false,"LinkLocalIPv6Address":"","LinkLocalIPv6PrefixLen":0,"Ports":{"80/tcp":[{"HostIp":"0.0.0.0","HostPort":"9002"},{"HostIp":"::","HostPort":"9002"}]},"SandboxKey":"/var/run/docker/netns/0f3f569dce91","SecondaryIPAddresses":null,"SecondaryIPv6Addresses":null,"EndpointID":"553e63fa029a7dc7e123c74b330830033fdcc2a409baae5745e3875d17d6d580","Gateway":"172.17.0.1","GlobalIPv6Address":"","GlobalIPv6PrefixLen":0,"IPAddress":"172.17.0.3","IPPrefixLen":16,"IPv6Gateway":"","MacAddress":"02:42:ac:11:00:03","Networks":{"bridge":{"IPAMConfig":null,"Links":null,"Aliases":null,"NetworkID":"c8af3e9943e0555af10ad6436ec37906039780a897e6ed0c0eb1655c0847f65e","EndpointID":"553e63fa029a7dc7e123c74b330830033fdcc2a409baae5745e3875d17d6d580","Gateway":"172.17.0.1","IPAddress":"172.17.0.3","IPPrefixLen":16,"IPv6Gateway":"","GlobalIPv6Address":"","GlobalIPv6PrefixLen":0,"MacAddress":"02:42:ac:11:00:03","DriverOpts":null}}} 下面尽管输入了 JSON 格局, 然而挤在一起太乱了，要输入 pretty 的 JSON.
# 应用 jq 命令行格式化 json
$ docker inspect -f '{{json .NetworkSettings.Networks}}' nginx | jq
# or
$ docker inspect -f '{{json .NetworkSettings.Networks}}' nginx | python -m json.tool 留神：python 命令行工具可能显示 'json' is a package and cannot be directly executed，这样的话先执行上面命令。

docker-desktop-data:
docker 创立的容器寄存在这里，这个如同是 Windows 零碎中，应用了 WSL 才会呈现的，实质其实就是一个 零碎虚拟机，只是比拟非凡。

Windows:
WSL:
win + e 关上 explorer(资源管理器)——> 在 explorer(资源管理器) 的地址栏输出 \\wsl$\docker-desktop-data 关上 docker-desktop-data.
Containers:
在下面说了 docker-desktop-data 是 docker 寄存 containers 的虚拟机，一些 containers 的配置也是寄存在这里的。
docker-desktop 19.03.13-beta2 开始 containers 的配置都放在这上面
