删除 docker 镜像后的消息

  • 772

使用命令删除旧的 docker 镜像后

docker images --no-trunc --format "{{.ID}} {{.CreatedSince}}" | grep " months" | awk "{ print $1 }" | xargs --no-run-if-empty docker rmi || true

在响应中，除了远程图像之外，还会发出以下内容：

Error: No such image: 2
Error: No such image: months
Error: No such image: ago
Error: No such image: 2

依此类推。你能告诉我为什么他试图找到这些名字的图像，我怎样才能摆脱这个？

    因为 awk 的双引号结构为您提供了完整的字符串

    docker images --no-trunc --format "{{.ID}} {{.CreatedSince}}" | grep " months" | awk "{ print $1 }"

    因此，您可以删除图像并尝试删除不存在的图像:)

    实际上，正如您已经猜到的那样，这种设计将正常工作

    docker images --no-trunc --format "{{.ID}} {{.CreatedSince}}" | grep " months" | awk '{ print $1 }'
