Docker基本使用命令

# 以Redis为例子
docker pull redis

docker run \
-d \ # 后台运行
--name redis6 \ # 自定义名字
-p 6379:6379 \ # 端口映射
redis # 镜像名称
docker run -d --name redis6 -p 6379:6379 redis redis-server --appendonly yes --requirepass "123456" # 完整命令

docker attach 容器id

docker exec -it 容器id /bin/bash

docker stop 容器id

docker start 容器id

docker ps -a # 查看所有容器
docker ps # 查看运行中的容器

docker inspect 容器id

# 以MySQL为例子
docker run -d --name mysql8 -p 3306:3306 -v /data/mysql8/config:/etc/mysql/conf.d -v /data/mysql8/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 mysql
# 以上的命令可以参考：https://hub.docker.com/_/mysql，里面有详细介绍

# 先拉个CentOS镜像下来
docker pull centos
# 创建个容器
docker run -d -it --name centos1 centos
docker run -d -it --name centos2 centos

docker inspect centos1_id

docker network create centos-network
docker run -d -it --network centos-network --name centos3 centos
docker run -d -it --network centos-network --name centos4 centos
docker exec -it centos3_id /bin/bash
ping centos4 
# 所以当创建了一个network后 容器都能加入到这个网络里面，很方便
