过滤

过滤标志（-f或--filter）格式为“key = value”。如果有多个过滤器，则传递多个标志（例如--filter "foo=bar" --filter "bif=baz"）

目前支持的过滤器是：

直到（<timestamp>） - 只删除在给定时间戳之前创建的图像

标签（label=<key>，label=<key>=<value>，label!=<key>，或label!=<key>=<value>） -仅删除与图像（或没有，如果label!=...被使用）指定的标签。

until过滤器可以是 Unix 的时间戳，日期格式的时间戳，或持续时间字符串（例如，去10m，1h30m）计算相对于守护机器的时间。支持的格式为日期格式时间戳包括 RFC3339Nano，RFC3339 ，2006-01-02T15:04:05，2006-01-02T15:04:05.999999999，2006-01-02Z07:00和2006-01-02。如果您在时间戳结束时未提供时区偏移Z或+-00:00时区偏移，则将使用守护程序上的本地时区。在提供 Unix 时间戳时输入 seconds.nanoseconds ，其中 seconds 是自1970年1月1日（ UTC / GMT 午夜）以来经过的秒数，不包括闰秒（又名 Unix 纪元或 Unix 时间）以及可选的 .nanoseconds 字段是一秒不超过九位数的一小部分。

label过滤器接受两种格式。一个是label=...（label=<key>或label=<key>=<value>），它用指定的标签去除图像。另一种格式是label!=...（label!=<key>或label!=<key>=<value>），它删除没有指定标签的图像。

Docker 17

Docker 是一个开源的应用容器引擎，让开发者可以打包他们的应用以及依赖包到一个可移植的容器中，然后发布到任何流行的 Linux 机器上，也可以实现虚拟化。容器是完全使用沙箱机制，相互之间不会有任何接口。
