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：

dockerfile 复制代码

FROM ubuntu:22.04

RUN echo "aa"
RUN ls -ll

3.1. 不使用任何参数构建过程

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
