    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

    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

    root@UbuntuBase:/usr/local/docker/mysql# docker ps

    使用客户端工具连接 MySQL

    *如果连接不上,设置一下登录权限
    ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456'; 
    FLUSH PRIVILEGES;
    

    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-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

    sudo docker cp containerID:container_path host_path
