Environmental linux centos7:
1, uninstall the previous version of the docker engine
sudo yum the Remove docker-ce
sudo RM -rf / var / lib / docker
2, Docker package already included in the default CentOS-Extras software source inside. So you want to install docker, yum only need to run the following command:
# yum install docker
3、
After installation is complete, use the following command to start the docker services, and set it to boot:
# systemctl start docker.service
# systemctl enable docker.service
4, mirror source address modification
修改 /etc/docker/daemon.json 内容：
{
"registry-mirrors": ["https://xffvqg8p.mirror.aliyuncs.com"]
}
sudo systemctl daemon-reload
sudo systemctl restart docker
5, download the image (it can be understood as a Java class)
docker pull rabbitmq
6, create and launch container (it can be understood as an example of a Java class)
docker run --name rabbitmq -d -p 5675:5672 docker.io/rabbitmq
And allows the container to create a name for abbitmq, external port 5675, mirroring is docker.io/rabbitmq
7, docker exec -it rabbitmq1 / bin / bash into the container with the specified name
8, docker ps -a queries all containers
9, docker rm -f fe8cc8ca18ed delete container
10, why should the port mapping? When the container starts, if you do not configure port mapping host machines and virtual machines, external program is unable to access the virtual machine, because there is no port.
11, docker start redis:
docker pull redis
sudo docker run -t -i -p 192.168.1.150:6379:6379 redis:latest /bin/bash
Server: master node docker run -d -p 192.168.1.150:6379:6379 --name redis-master -v / home / redis /: / data docker.io/redis redis-server
slave节点 docker run -itd -p 192.168.1.150:6380:6380 --name redis-slave --link redis-master:master docker.io/redis /bin/bash
docker run -it --name redis-slave -d -p 192.168.1.150:6301:6379 docker.io/redis redis-server
客户端：docker run -it --link redis-master --rm docker.io/redis redis-cli -h redis-master -p 6379
docker run -it --link redis-slave --rm docker.io/redis redis-cli -h redis-slave -p 6379
12、
apt-get update
apt-get install vim
13、
Replicated from the host to the containersudo docker cp host_path containerID:container_path
sudo docker cp /home/redis.conf 42446750d633:/data
Copy from the container to the hostsudo docker cp containerID:container_path host_path
14、
Into the container: docker exec -it redis-slave bash

15, docker container being given network restart
docker start d23ae97077b7
Error response from daemon: Cannot restart container d23ae97077b7: driver failed programming external connectivity on endpoint zookeeper (eb77732e83cdbc7d04d262f0f5f524bad965bd35c5d770a635b35f7276c9c02f): (iptables failed: iptables --wait -t nat -A DOCKER -p tcp -d 0/0 --dport 2181 -j DNAT --to-destination 172.17.0.2:2181 ! -i docker0: iptables: No chain/target/match by that name.
Solution: systemctl restart docker (docker network management problems just fine the next reboot.);
docker start d23ae97077b7；
