1、创建测试镜像

Dockerfile:

FROM centos
LABEL maintainer="NGINX Docker Maintainers [e-mail]"
RUN yum install -y nginx
RUN echo "Nginx Web: CMD defining default arguments for an ENTRYPOINT" > /usr/share/nginx/html/index.html
EXPOSE 80
CMD ["-g", "daemon off;"]
ENTRYPOINT ["/usr/sbin/nginx"]

生成镜像：

docker build -t cjavapy/nginx:v1 .

2、使用docker history

1）命令

docker history --format {{.CreatedBy}} --no-trunc=true 镜像 |sed "s,/bin/\(ba\)\?sh[ ]-c[ ]\#(nop)[ ][ ]*,,g" |sed "s,/bin/\(ba\)\?sh[ ]-c,RUN,g" |sed 's,  *&&  *, \\\n \&\& ,g' |tac

2）命令用法

docker history --format {{.CreatedBy}} --no-trunc=true cjavapy/nginx:v1 |sed "s,/bin/\(ba\)\?sh[ ]-c[ ]\#(nop)[ ][ ]*,,g" |sed "s,/bin/\(ba\)\?sh[ ]-c,RUN,g" |sed 's,  *&&  *, \\\n \&\& ,g' |tac
