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

3.2. 使用DOCKER_BUILDKIT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.
