1. 背景
升级了docker版本，发现在构建镜像过程中，docker没有输出echo, ls, pwd等类似命令的类容，并且没有输出构建过程。老版本的docker则没有这个问题（具体哪个版本没有深究）
2. 解决方案
2.1. 方案一 （不推荐）
增加DOCKER_BUILDKIT参数，譬如这么执行构建命令：DOCKER_BUILDKIT=0 docker build .
2.2. 方案二 （强烈推荐）
增加--progress=plain参数，譬如这么执行构建命令：docker build --no-cache --progress=plain .
3. 测试
dockerfile测试文件如下：
FROM ubuntu:22.04
RUN echo "aa"
RUN ls -ll
3.1. 不使用任何参数构建过程

[root@8f7059cd1fc5 ~/test-dockerfile]# DOCKER_BUILDKIT=0 docker build --no-cache .
DEPRECATED: The legacy builder is deprecated and will be removed in a future release.
BuildKit is currently disabled; enable it by removing the DOCKER_BUILDKIT=0
environment-variable.
