这里我们拉取官方的镜像
docker pull tomcat
等待下载完成后，我们就可以在本地镜像列表里查到 REPOSITORY 为 tomcat 的镜像。
docker images
运行容器：
暴露tomcat容器到宿主机的8080端口
docker run --name tomcat -p 8080:8080 -v $PWD/test:/usr/local/tomcat/webapps/test -d tomcat
命令说明：
- -p 8080:8080：将容器的8080端口映射到主机的8080端口
- -v $PWD/test:/usr/local/tomcat/webapps/test：将主机中当前目录下的test挂载到容器的/test
查看容器启动情况
root@UbuntuBase:/usr/local/docker/tomcat/webapps# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
38498e53128c tomcat "catalina.sh run" 2 minutes ago Up 2 minutes 0.0.0.0:8080->8080/tcp tomcat

这里我们拉取官方的镜像
docker pull mysql
等待下载完成后，我们就可以在本地镜像列表里查到 REPOSITORY 为 mysql 的镜像
运行容器：
docker run -p 3306:3306 --name mysql \
-v /usr/local/docker/mysql/conf:/etc/mysql \
-v /usr/local/docker/mysql/logs:/var/log/mysql \
-v /usr/local/docker/mysql/data:/var/lib/mysql \
-v /usr/local/docker/mysql-files:/var/lib/mysql-files \
-e MYSQL_ROOT_PASSWORD=123456 \
-d mysql
命令参数：
-p 3306:3306：将容器的3306端口映射到主机的3306端口-v /usr/local/docker/mysql/conf:/etc/mysql：将主机当前目录下的 conf 挂载到容器的 /etc/mysql-v /usr/local/docker/mysql/logs:/var/log/mysql：将主机当前目录下的 logs 目录挂载到容器的 /var/log/mysql-v /usr/local/docker/mysql/data:/var/lib/mysql：将主机当前目录下的 data 目录挂载到容器的 /var/lib/mysql-e MYSQL\_ROOT\_PASSWORD=123456：初始化root用户的密码
查看容器启动情况

部署项目到容器
解决多容器的网络问题
#创建子网
sudo docker network create --subnet 172.10.0.1/16 my_net
#mysql加入子网
docker run -p 3306:3306 --net=my_net --name mysql \
-v /usr/local/docker/mysql/conf:/etc/mysql \
-v /usr/local/docker/mysql/logs:/var/log/mysql \
-v /usr/local/docker/mysql/data:/var/lib/mysql \
-v /usr/local/docker/mysql-files:/var/lib/mysql-files \
-e MYSQL_ROOT_PASSWORD=123456 \
-d mysql
#tomcat加入子网
docker run --name tomcat --net=my_net -p 8080:8080 -v $PWD/test:/usr/local/tomcat/webapps/ROOT -d tomcat
Docker 常用命令
查看 Docker 版本
docker version
从 Docker 文件构建 Docker 映像
docker build -t image-name docker-file-location
运行 Docker 映像
docker run -d image-name
查看可用的 Docker 映像
docker images
查看最近的运行容器
docker ps -l
查看所有正在运行的容器
docker ps -a
停止运行容器
docker stop container_id
删除一个镜像
docker rmi image-name
删除所有镜像
docker rmi $(docker images -q)
强制删除所有镜像
docker rmi -r $(docker images -q)
删除所有虚悬镜像
docker rmi $(docker images -q -f dangling=true)
删除所有容器
docker rm $(docker ps -a -q)
进入 Docker 容器
docker exec -it container-id /bin/bash
查看所有数据卷
docker volume ls
删除指定数据卷
docker volume rm [volume_name]
删除所有未关联的数据卷
docker volume rm $(docker volume ls -qf dangling=true)
从主机复制文件到容器
sudo docker cp host_path containerID:container_path
从容器复制文件到主机
