开启docker,并设置开机自启动
老式写法:
service docker start
chkconfig docker on
新式写法:
systemctl start docker.service
systemctl enable docker.service
Build an image from a Dockerfile
docker build -t friendlyhello .
tag一个image,并push
语法:
docker tag SOURCE_IMAGE[:TAG] TARGET_IMAGE[:TAG]
docker push username/repository:tag
示例:
[root@localhost ~]# docker login //登录
[root@localhost ~]# docker tag friendlyhello ssslinppp/get-started:part1 //tag
[root@localhost ~]# docker images
