首先需要去docker官网注册你的账号,记住账号名称和密码;
然后在本地执行:
docker login
登录OK。
把ubuntu下载到本地:
sudo docker pull ubuntu
sudo docker images
输出:
REPOSITORY TAG IMAGE ID CREATED SIZE
hehui09125214254/myubuntu3 latest 7502f9dc5b76 2 minutes ago 199MB
hehui09125214254/myubuntu2 latest 93ae962924f0 6 minutes ago 199MB
hehui09125214254/myubuntu latest b2e9d5090857 2 hours ago 199MB
hehui09125214254/myubuntu <none> 01043a42b0da 2 hours ago 199MB
运行第一个:
sudo docker run -it 7502f9dc5b76
然后修改文件,然后commit:
sudo docker ps -a
输出:

我们把第一个 commit。
sudo docker commit c03b677d524c hehui09125214254/myubuntu3:tag1
push
sudo docker push hehui09125214254/myubuntu3:tag1
然后去 https://hub.docker.com/repositories 查看,已经上传了。
sudo systemctl enable docker
sudo systemctl status docker
sudo systemctl disable docker
this command changes the restart policy for an already running container named redis.
docker update --restart unless-stopped redis
And this command will ensure all currently running containers will be restarted unless stopped.
docker update --restart unless-stopped $(docker ps -q)
docker :
安装 : https://docs.docker.com/engine/install/ubuntu/
sudo apt-get install docker-ce=5:20.10.13-0ubuntu-focal docker-ce-cli=5:20.10.13-0ubuntu-focal containerd.io
查看docker容器的ip:
iptables -t nat -L -n
以下确定没有问题
https://blog.usejournal.com/how-to-enable-docker-remote-api-on-docker-host-7b73bd3278c6
https://blog.csdn.net/qq_35615618/article/details/81201646
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock
sudo systemctl daemon-reload
sudo systemctl restart docker
3.修改配置后:
sudo systemctl daemon-reload
sudo service docker restart
5.测试:
sudo docker run hello-world
6.编译镜像:
mvn clean package docker:build -DskipTests
7.docker 卸载重装

8:成功案例:==========================================
https://www.jianshu.com/p/dfc0ed56ebb1
》mvn clean package docker:build -Dmaven.test.skip=true
》docker run -d --name test -p 47.111.155.40:9000:9000 demo 指定IP
》docker run -d --name 容器名字 -p 9000:9000 镜像名字 // 不指定IP(=======采用这个。。。。。+ eureka )
docker run -d --net=host --privileged=true --name test -p 9000:9000 demo // 采用本机的IP(====== ok =========)
docker run -itd --name hadoop0 --hostname hadoop0 --net network_my --ip 192.168.10.30 --add-host hadoop1:192.168.10.31 --add-host hadoop2:192.168.10.32 -d -P -p 50070:50070 -p 8088:8088 hadoop:master
docker run -itd --name hadoop20 --hostname 47.111.155.40 --ip 47.111.155.40 --add-host 47.111.155.40:47.111.155.40 -d -P -p 9000:9000 demo
-p(小写)则可以指定要映射的IP和端口,但是在一个指定端口上只可以绑定一个容器
docker run --add-host=myhostname:47.111.155.40 --name test -it debian
9:同一个镜像,可以同时在多个容器中运行,
10:容器删除:
1)首先需要停止所有的容器
docker stop $(docker ps -a -q)
2)删除所有的容器(只删除单个时把后面的变量改为image id即可)
docker rm $(docker ps -a -q)
3.Is the docker daemon running?
service docker start
// 运行一个容器时,关联一个数据卷容器
docker run -itd --name ssh_server_test --volumes-from data1 -p 8991:22 7698f282e524
