3.查看
//命令 docker version //查看docker的版本号 [root@localhost ~]# docker version Client: Version: 18.06.3-ce API version: 1.38 Go version: go1.10.3 Git commit: d7080c1 Built: Wed Feb 20 02:26:51 2019 OS/Arch: linux/amd64 Experimental: false Server: Engine: Version: 18.06.3-ce API version: 1.38 (minimum version 1.12) Go version: go1.10.3 Git commit: d7080c1 Built: Wed Feb 20 02:28:17 2019 OS/Arch: linux/amd64 Experimental: false //命令 docker info //更详细的查看docker的运行信息，镜像数和容器数都能看到 [root@localhost ~]# docker info Containers: 2 Running: 0 Paused: 0 Stopped: 2 Images: 2 Server Version: 18.06.3-ce Storage Driver: overlay2 Backing Filesystem: xfs Supports d_type: true Native Overlay Diff: true Logging Driver: json-file Cgroup Driver: cgroupfs Plugins: Volume: local Network: bridge host macvlan null overlay Log: awslogs fluentd gcplogs gelf journald json-file logentries splunk syslog Swarm: inactive Runtimes: runc Default Runtime: runc Init Binary: docker-init containerd version: 468a545b9edcd5932818eb9de8e72413e616e86e runc version: a592beb5bc4c4092b1b1bac971afed27687340c5 init version: fec3683 Security Options: seccomp Profile: default Kernel Version: 3.10.0-1160.80.1.el7.x86_64 Operating System: CentOS Linux 7 (Core) OSType: linux Architecture: x86_64 CPUs: 2 Total Memory: 1.786GiB Name: localhost.localdomain ID: OCD3:Y4KG:A4VS:WBS6:IK2G:DFKX:5CBX:IZWD:TPEV:ZBR5:GXOS:4JKL Docker Root Dir: /var/lib/docker Debug Mode (client): false Debug Mode (server): false Registry: https://index.docker.io/v1/ Labels: Experimental: false Insecure Registries: 127.0.0.0/8 Live Restore Enabled: false
二、docker的镜像命令
1.查看镜像
//命令 docker images(查看服务器已有的镜像） [root@localhost ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE hello-world latest feb5d9fea6a5 14 months ago 13.3kB centos latest 5d0da3dc9764 14 months ago 231MB
2.搜索镜像
//命令 docker search 镜像名（搜索镜像） [root@localhost ~]# docker search mysql NAME DESCRIPTION STARS OFFICIAL AUTOMATED mysql MySQL is a widely used, open-source relation… 13510 [OK] mariadb MariaDB Server is a high performing open sou… 5156 [OK] phpmyadmin phpMyAdmin - A web interface for MySQL and M… 696 [OK] percona Percona Server is a fork of the MySQL relati… 594 [OK] bitnami/mysql Bitnami MySQL Docker Image 79 [OK] databack/mysql-backup Back up mysql databases to... anywhere! 74 linuxserver/mysql-workbench 45 ubuntu/mysql MySQL open source fast, stable, multi-thread… 38 linuxserver/mysql A Mysql container, brought to you by LinuxSe… 38 circleci/mysql MySQL is a widely used, open-source relation… 28 google/mysql MySQL server for Google Compute Engine 22 [OK] rapidfort/mysql RapidFort optimized, hardened image for MySQL 13 bitnami/mysqld-exporter 4 ibmcom/mysql-s390x Docker image for mysql-s390x 2 newrelic/mysql-plugin New Relic Plugin for monitoring MySQL databa… 1 [OK] vitess/mysqlctld vitess/mysqlctld 1 [OK] hashicorp/mysql-portworx-demo 0 rapidfort/mysql-official RapidFort optimized, hardened image for MySQ… 0 docksal/mysql MySQL service images for Docksal - https://d… 0 mirantis/mysql 0 rapidfort/mysql8-ib RapidFort optimized, hardened image for MySQ… 0 cimg/mysql 0 drud/mysql 0 silintl/mysql-backup-restore Simple docker image to perform mysql backups… 0 [OK] corpusops/mysql https://github.com/corpusops/docker-images/ 0 //搜索stars>9000的mysql镜像 [root@localhost ~]# docker search --filter=stars=9000 mysql NAME DESCRIPTION STARS OFFICIAL AUTOMATED mysql MySQL is a widely used, open-source relation… 13510 [OK]
3.下载镜像
注意：我们下载的镜像必须是在仓库中能查找到的！！！可以先登录仓库网址查询要下载的镜像及版本。docker仓库官网：https://hub.docker.com/
比如进docker仓库查询一下mysql的镜像及版本：
拉取镜像：
命令：docker pull 镜像名（默认是最新版的）
docker pull 镜像名:tag（拉取指定版本的镜像）
//从仓库拉取mysql镜像 [root@localhost ~]# docker pull mysql:latest latest: Pulling from library/mysql 0bb5c0c24818: Pull complete cbb3106fbb5a: Pull complete 550536ae1d5e: Pull complete 33f98928796e: Pull complete a341087cff11: Pull complete 0e26ac5b33f6: Pull complete c883b83a7112: Pull complete 873af5c876c6: Pull complete 8fe8ebd061d5: Pull complete 7ac2553cf6b4: Pull complete ad655e218e12: Pull complete Digest: sha256:96439dd0d8d085cd90c8001be2c9dde07b8a68b472bd20efcbe3df78cff66492 Status: Downloaded newer image for mysql:latest
4.运行镜像并生成容器
//命令 docker run 镜像名:tag /bin/bash //-it表示以交互式运行 [root@localhost ~]# docker run -it mysql:latest /bin/bash bash-4.4# //使用Ctrl+P+Q退出容器，用docker ps查看刚才运行的容器 bash-4.4# [root@localhost ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 115c9b4f1e0e mysql:latest "docker-entrypoint.s…" 2 minutes ago Up 2 minutes 3306/tcp, 33060/tcp sharp_easley
5.删除镜像

三、docker的容器命令
1.查看容器
//命令 docker ps（查看正在运行的容器） [root@localhost ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 16c1136241dd mysql "docker-entrypoint.s…" 2 minutes ago Up 2 minutes 3306/tcp, 33060/tcp upbeat_blackwell //命令 docker ps -a（查看所有的容器，包括正在运行和已经停止的） [root@localhost ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES c70259707a44 centos "/bin/bash" About a minute ago Exited (0) 15 seconds ago objective_saha 16c1136241dd mysql "docker-entrypoint.s…" 2 minutes ago Up 2 minutes 3306/tcp, 33060/tcp upbeat_blackwell
2.运行容器
//命令 docker run -it -d --name 要取的别名 镜像名:tag /bin/bash //-it 表示与容器进行交互式启动 //-d表示可后台运行容器 //--name给要运行的容器取的名 //以交互式启动mysql容器 [root@localhost ~]# docker run -it mysql /bin/bash bash-4.4# [root@localhost ~]# //以交互式启动centos容器 [root@localhost ~]# docker run -it centos /bin/bash [root@b56d0be965aa /]# [root@localhost ~]# [root@localhost ~]# //查看当前正在运行的容器 [root@localhost ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES b56d0be965aa centos "/bin/bash" 30 seconds ago Up 28 seconds reverent_williams 26b580adce05 mysql "docker-entrypoint.s…" About a minute ago Up About a minute 3306/tcp, 33060/tcp jovial_johnson 16c1136241dd mysql "docker-entrypoint.s…" 11 minutes ago Up 11 minutes 3306/tcp, 33060/tcp upbeat_blackwell //命令 docker exec -it 容器id /bin/bash（以交互式进入当前正在运行的容器） [root@localhost ~]# docker exec -it b56d0be965aa /bin/bash [root@b56d0be965aa /]# [root@b56d0be965aa /]# read escape sequence //命令 docker attach 容器id（进入当前正在运行的容器） [root@localhost ~]# docker attach b56d0be965aa [root@b56d0be965aa /]# ls bin dev etc home lib lib64 lost+found media mnt opt proc root run sbin srv sys tmp usr var //exit停止容器并且退出 [root@b56d0be965aa /]# exit exit [root@localhost ~]#
3.进入容器
有两种方式：①docker exec -it 容器id /bin/bash（进入正在运行的容器后悔开启一个新的终端，常用）；②docker attach 容器id（进入容器后直接进行正在执行的终端，不会开启新的终端）
//命令 docker exec -it 容器id /bin/bash（以交互式进入当前正在运行的容器） [root@localhost ~]# docker exec -it b56d0be965aa /bin/bash [root@b56d0be965aa /]# [root@b56d0be965aa /]# read escape sequence //命令 docker attach 容器id（进入当前正在运行的容器） [root@localhost ~]# docker attach b56d0be965aa [root@b56d0be965aa /]# ls bin dev etc home lib lib64 lost+found media mnt opt proc root run sbin srv sys tmp usr var
4.退出容器
也有两种方式：①exit,这种方式会直接将当前运行的容器停止掉退出；②Ctrl+P+Q，这种不停止当前的容器进行退出。
[root@localhost ~]# docker exec -it 26b580adce05 /bin/bash //使用exit退出，直接容器停止并且退出 bash-4.4# exit exit [root@localhost ~]# [root@localhost ~]# docker exec -it 26b580adce05 /bin/bash //使用Ctrl+P+Q容器不停止退出 bash-4.4# read escape sequence [root@localhost ~]#
5.删除容器

四、其他常用命令
1.后台启动容器
//命令 docker run -d 镜像名 [root@localhost ~]# docker run -d centos 917388d45cea522f4e63a48c080cda2d394c148ad4b770f364b43e81f21dd8ea
2.查看日志
//命令 docker logs -tf --tail num 容器id //-tf 表示显示日志 //--tail num 表示显示日志的条数 //查看id为917388d45cea容器的10条日志 [root@localhost ~]# docker logs -tf --tail 10 917388d45cea
3.查看容器中的进程信息
//命令 docker top 容器id [root@localhost ~]# docker top 4158303298d0 UID PID PPID C STIME TTY TIME CMD root 11193 11175 1 11:52 ? 00:00:00 /bin/bash

5.从容器中拷贝文件到宿主机
//进入centos容器 [root@localhost ~]# docker run -it centos /bin/bash [root@aa63b6c1dc9d /]# ls bin dev etc home lib lib64 lost+found media mnt opt proc root run sbin srv sys tmp usr var //在centos容器的home目录下创建一个zhangsan.java文件 [root@aa63b6c1dc9d /]# cd home [root@aa63b6c1dc9d home]# touch zhangsan.java [root@aa63b6c1dc9d home]# ls zhangsan.java [root@aa63b6c1dc9d home]# [root@localhost ~]# //命令 docker cp 容器id:容器内路径 宿主机的保存路径 //将id为aa63b6c1dc9d容器中的home下的zhangsan.java文件拷贝到宿主机的/home中 [root@localhost ~]# docker cp aa63b6c1dc9d:/home/zhangsan.java /home [root@localhost ~]# cd / [root@localhost /]# ls bin boot dev etc home lib lib64 media mnt opt proc root run sbin srv sys tmp usr var [root@localhost /]# cd home [root@localhost home]# ls test.java zhangsan.java
docker的命令还有很多，以上是最基本的，一起努力！！！
