Question

我们如何在docker history命令的输出中看到第三列（CREATED BY）中的完整命令？

$ docker history docker.company.net/docker-base-images/image:1.0

IMAGE               CREATED             CREATED BY                                      SIZE

第三列（CREATED BY）缩写了命令，这使得重建原始Dockerfile变得困难。是否可以在第三列中获取完整命令？

谢谢阅读。

您可以添加标志--no-trunc以查看完整命令。
