docker 镜像制作 commit --entrypoint
commit --entrypoint测试
替换原来镜像中的ENTRYPOINT["/bin/bash"]
docker run -it --entrypoint ./hello --name testgo3 centosgo:v1
docker run -it --entrypoint /bin/bash --name testgo4 centosgo:v2
1、编写批处理文件
-- start.sh
#!/bin/sh
/go/hello
2、批处理文件复制到容器中
docker cp start.sh 57878d8265f4:/
3、从容器生成新的镜像
docker commit -m "test message" -a "auther" -c "ENTRYPOINT /start.sh" 57878d8265f4 centosgo:v3
4、启动新的容器
docker run -it --name testgo5 centosgo:v3
Hello, world! 【执行批处理后的输出】
5、docker ps -a

6、docker inspect testgo5
