前言
现在搭建部署环境基本都是用Docker进行，学会Docker指令相当重要。在我的Docker系列文章中我们已经进行了很多准备工作，我是在云服务器上面进行部署的工作，大大省去了虚拟机环境配置时间，大家可以用用看：
云服务器Centos8.2SSH登陆、安装部署图形化界面以及VNC连接一文详解
云服务器CentOS8.2安装部署Docker一文详解
云服务器CentOS8.2Docker图形化管理工具Portainer安装部署
下面仍旧还是使用SecureCRT进行指令演示。
很多学Python伙伴问题有没有体系的面试题？
今天为大家推荐一款刷题神奇哦 ：刷题面试神器牛客
各大互联网大厂面试真题。从基础到入阶乃至原理刨析类面试题 应有尽有，赶快来装备自己吧！助你面试稳操胜券，solo全场面试官
一、Docker基础命令
1.启动docker
systemctl start docker2.查看状态
systemctl status docker
3.关闭docker
systemctl stop docker
4.开机自启
systemctl enable docker5.查看版本信息
docker versiondocker info
6.查看帮助
docker --help若忘记了某个指令的功能可以在后面加上help查看功能：
docker 指令参数 --help
二、Docker镜像命令
1.查看docker镜像
docker images
可以通过--help查看每一个Image命令的详细信息。
docker image ls --help
显示所有镜像（默认隐藏中间图像）
docker image ls -a
docker images、docker image ls和docker image ls -a是一样的效果。
docker image ls -q仅输出image的IMAGE ID。
2.搜索镜像
docker search 镜像名比如：
docker search [OPTIONS] TERM其中OPTIONS有：
--automated：弃用，只列出自动构建类型的镜像--filter , -f：基于给定条件过滤输出--format：使用模板格式化显示输出 --limit：Max number of search results ，默认值25--no-trunc：禁止截断输出--stars , -s：弃用，只显示收藏数不小于几颗星的镜像，移到--filter中使用代码如下（示例）：
搜索不小于10000星的busybox的镜像
docker search --filter=stars=10000 mysqlformat格式化输出
.Description 镜像描述.StarCount star数量 .IsOfficial “OK” 表示官方镜像.IsAutomated “OK” 表示自动构建docker search --format "{{.Name}}:{{.StarCount}}" mysql
docker search --format "table {{.Name}}\t{{.IsAutomated}}\t{{.IsOfficial}}" redis
限制搜索输出个数
docker search redis --filter=stars=500 --limit 3
禁止截断输出
docker search --no-trunc mysql 
3.拉取镜像
代码如下（示例）：
docker image pull参数可以选有两个：
例如拉取一个最新的redis：
docker image pull redis 
拉取完后docker images查看：
4.删除所有镜像
代码如下：
docker image prune [OPTIONS]
5.删除指定镜像
docker image rm [OPTIONS] IMAGE [IMAGE...] 
删除TAG为latest最新版本的redis：
docker image rm redis:latest
6.TAG修改生成新镜像
docker image tag SOURCE_IMAGE[:TAG] TARGET_IMAGE[:TAG] 
docker image tag hello-world:latest hello-world:v.1.0
7.保存镜像
docker image save [OPTIONS] IMAGE [IMAGE...]
docker image save hello-world:v.1.0 > hw.tar
保存到指定目录：
docker image save hello-worl:v.1.0 -o /usr/local/hw.tar8.加载镜像
docker image load [OPTIONS]
我们一开始是把hello-world的v.1.0的版本给删了，现在我们可以把通过本地保存的hello-world给放到image里面去：
docker image load <hw.tar 
加载指定路径的镜像源：
docker load -i /usr/local/hw.tar # 指定加载镜像的源9.显示历史镜像操作
docker image history [OPTIONS] IMAGE
docker image history hello-world:v.1.0
10.显示镜像的详细信息
docker image inspect [OPTIONS] IMAGE [IMAGE...]例如我们查看hello-world镜像的详细信息会发现：
docker image inspect hello-world 一大串JSON文件格式：
11.从归档文件中创建镜像
docker image import [OPTIONS] file|URL|- [REPOSITORY[:TAG]]
docker image import hw.tar # 一般需要指定镜像名字12.上传镜像
docker image push [OPTIONS] NAME[:TAG]
这样就是上传成功了可以在dockerhub上看到自己上传的镜像：
docker push fanstuck/my-private-repo:hellow-world
13.创建镜像
docker image build [OPTIONS] PATH | URL | -bulid属于制作镜像是一个较为复杂且需要编写程序的过程，因此参数相应的会比较复杂：
Usage: docker [OPTIONS] COMMANDA self-sufficient runtime for containersOptions: --config string Location of client config files (default "/root/.docker") -c, --context string Name of the context to use to connect to the daemon (overrides DOCKER_HOST env var and default context set with "docker context use") -D, --debug Enable debug mode -H, --host list Daemon socket(s) to connect to -l, --log-level string Set the logging level ("debug"|"info"|"warn"|"error"|"fatal") (default "info") --tls Use TLS; implied by --tlsverify --tlscacert string Trust certs signed only by this CA (default "/root/.docker/ca.pem") --tlscert string Path to TLS certificate file (default "/root/.docker/cert.pem") --tlskey string Path to TLS key file (default "/root/.docker/key.pem") --tlsverify Use TLS and verify the remote -v, --version Print version information and quitManagement Commands: app* Docker App (Docker Inc., v0.9.1-beta3) builder Manage builds buildx* Build with BuildKit (Docker Inc., v0.6.3-docker) compose* Docker Compose (Docker Inc., v2.6.0) config Manage Docker configs container Manage containers context Manage contexts image Manage images manifest Manage Docker image manifests and manifest lists network Manage networks node Manage Swarm nodes plugin Manage plugins scan* Docker Scan (Docker Inc., v0.17.0) secret Manage Docker secrets service Manage services stack Manage Docker stacks swarm Manage Swarm system Manage Docker trust Manage trust on Docker images volume Manage volumesCommands: attach Attach local standard input, output, and error streams to a running container build Build an image from a Dockerfile commit Create a new image from a container's changes cp Copy files/folders between a container and the local filesystem create Create a new container diff Inspect changes to files or directories on a container's filesystem events Get real time events from the server exec Run a command in a running container export Export a container's filesystem as a tar archive history Show the history of an image images List images import Import the contents from a tarball to create a filesystem image info Display system-wide information inspect Return low-level information on Docker objects kill Kill one or more running containers load Load an image from a tar archive or STDIN login Log in to a Docker registry logout Log out from a Docker registry logs Fetch the logs of a container pause Pause all processes within one or more containers port List port mappings or a specific mapping for the container ps List containers pull Pull an image or a repository from a registry push Push an image or a repository to a registry rename Rename a container restart Restart one or more containers rm Remove one or more containers rmi Remove one or more images run Run a command in a new container save Save one or more images to a tar archive (streamed to STDOUT by default) search Search the Docker Hub for images start Start one or more stopped containers stats Display a live stream of container(s) resource usage statistics stop Stop one or more running containers tag Create a tag TARGET_IMAGE that refers to SOURCE_IMAGE top Display the running processes of a container unpause Unpause all processes within one or more containers update Update configuration of one or more containers version Show the Docker version information wait Block until one or more containers stop, then print their exit codesRun 'docker COMMAND --help' for more information on a command.这里参数十分丰富，以后将独自写一期docker bulid来详细介绍该功能的使用，属于制作镜像一块的，是比较大的一块docker内容。
14.运行镜像
创建一个新的容器并运行一个命令
