过滤

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

目前支持的过滤器是:

  • until(<timestamp>) - 仅删除在给定时间戳之前创建的容器,图像和网络

  • label (label=<key>, label=<key>=<value>, label!=<key>,或label!=<key>=<value>)-仅删除带有%的容器、图像、网络和卷(以防万一label!=...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10m1h30m)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, ,2006-01-02T15:04:052006-01-02T15:04:05.9999999992006-01-02Z07:002006-01-02。如果您在时间戳结束时未提供时区偏移Z+-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>label=<key>=<value>),它使用指定的标签删除容器、图像、网络和卷。另一种格式是label!=...label!=<key>label!=<key>=<value>),它在没有指定标签的情况下删除容器、图像、网络和卷。
