一、拉取镜像

1.检测镜像是否存在

[root@node1 ~]# docker search nginxNAME                              DESCRIPTION                                     STARS     OFFICIAL   AUTOMATEDnginx                             Official build of Nginx.                        15187     [OK]       jwilder/nginx-proxy               Automated Nginx reverse proxy for docker con…   2048                 [OK]richarvey/nginx-php-fpm           Container running Nginx + PHP-FPM capable of…   816                  [OK]jc21/nginx-proxy-manager          Docker container for managing Nginx proxy ho…   218                  linuxserver/nginx                 An Nginx container, brought to you by LinuxS…   149                  tiangolo/nginx-rtmp               Docker image with Nginx using the nginx-rtmp…   136                  [OK]jlesage/nginx-proxy-manager       Docker container for Nginx Proxy Manager        123                  [OK]alfg/nginx-rtmp                   NGINX, nginx-rtmp-module and FFmpeg from sou…   102                  [OK]jasonrivers/nginx-rtmp            Docker images to host RTMP streams using NGI…   92                   [OK]nginxdemos/hello                  NGINX webserver that serves a simple page co…   70                   [OK]privatebin/nginx-fpm-alpine       PrivateBin running on an Nginx, php-fpm & Al…   56                   [OK]nginx/nginx-ingress               NGINX and  NGINX Plus Ingress Controllers fo…   55                   nginxinc/nginx-unprivileged       Unprivileged NGINX Dockerfiles                  45                   staticfloat/nginx-certbot         Opinionated setup for automatic TLS certs lo…   24                   [OK]nginx/nginx-prometheus-exporter   NGINX Prometheus Exporter for NGINX and NGIN…   19                   schmunk42/nginx-redirect          A very simple container to redirect HTTP tra…   19                   [OK]centos/nginx-112-centos7          Platform for running nginx 1.12 or building …   15                   centos/nginx-18-centos7           Platform for running nginx 1.8 or building n…   13                   raulr/nginx-wordpress             Nginx front-end for the official wordpress:f…   13                   [OK]bitwarden/nginx                   The Bitwarden nginx web server acting as a r…   11                   flashspys/nginx-static            Super Lightweight Nginx Image                   10                   [OK]mailu/nginx                       Mailu nginx frontend                            9                    [OK]sophos/nginx-vts-exporter         Simple server that scrapes Nginx vts stats a…   7                    [OK]ansibleplaybookbundle/nginx-apb   An APB to deploy NGINX                          2                    [OK]wodby/nginx                       Generic nginx                                   1

2.拉取下载镜像

[root@node1 ~]# docker pull nginxUsing default tag: latestlatest: Pulling from library/nginxb4d181a07f80: Pull complete 66b1c490df3f: Pull complete d0f91ae9b44c: Pull complete baf987068537: Pull complete 6bbc76cbebeb: Pull complete 32b766478bc2: Pull complete Digest: sha256:353c20f74d9b6aee359f30e8e4f69c3d7eaea2f610681c4a95849a2fd7c497f9Status: Downloaded newer image for nginx:latestdocker.io/library/nginx:latest

3.查看本地镜像

[root@node1 ~]# docker image lsREPOSITORY   TAG       IMAGE ID       CREATED       SIZEnginx        latest    4cdc5dd7eaad   2 weeks ago   133MB

二、运行镜像

1.安装相关包

[root@node1 ~]# yum install -y libseccomp-devel Updating Subscription Management repositories.Unable to read consumer identityThis system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.Repository AppStream is listed more than once in the configurationRepository AppStream is listed more than once in the configurationRepository BaseOS is listed more than once in the configurationRepository AppStream is listed more than once in the configurationRepository BaseOS is listed more than once in the configurationDocker CE Nightly - Sources                                                                                    798  B/s | 2.3 kB     00:02    ansiable                                                                                                       0.0  B/s |   0  B     00:00    Failed to synchronize cache for repo 'docker-ce-nightly-source', ignoring this repo.Failed to synchronize cache for repo 'ansiable', ignoring this repo.Last metadata expiration check: 2:32:21 ago on Wed 21 Jul 2021 07:51:23 PM CST.Dependencies resolved.=============================================================================================================================================== Package                                Arch                         Version                             Repository                       Size===============================================================================================================================================Installing: libseccomp-devel                       x86_64                       2.5.1-1.el8                         AppStream                        57 kUpgrading: libseccomp                             x86_64                       2.5.1-1.el8                         base                             71 kTransaction Summary===============================================================================================================================================Install  1 PackageUpgrade  1 PackageTotal download size: 128 kDownloading Packages:(1/2): libseccomp-2.5.1-1.el8.x86_64.rpm                                                                       256 kB/s |  71 kB     00:00    (2/2): libseccomp-devel-2.5.1-1.el8.x86_64.rpm                                                                 186 kB/s |  57 kB     00:00    -----------------------------------------------------------------------------------------------------------------------------------------------Total                                                                                                          414 kB/s | 128 kB     00:00     Running transaction checkTransaction check succeeded.Running transaction testTransaction test succeeded.Running transaction  Preparing        :                                                                                                                       1/1   Upgrading        : libseccomp-2.5.1-1.el8.x86_64                                                                                         1/3   Running scriptlet: libseccomp-2.5.1-1.el8.x86_64                                                                                         1/3   Installing       : libseccomp-devel-2.5.1-1.el8.x86_64                                                                                   2/3   Cleanup          : libseccomp-2.3.3-3.el8.x86_64                                                                                         3/3   Running scriptlet: libseccomp-2.3.3-3.el8.x86_64                                                                                         3/3   Verifying        : libseccomp-devel-2.5.1-1.el8.x86_64                                                                                   1/3   Verifying        : libseccomp-2.5.1-1.el8.x86_64                                                                                         2/3   Verifying        : libseccomp-2.3.3-3.el8.x86_64                                                                                         3/3 Installed products updated.Upgraded:  libseccomp-2.5.1-1.el8.x86_64                                         Installed:  libseccomp-devel-2.5.1-1.el8.x86_64                                                                                                         Complete!

2.生成容器

备注:- d 后台运行容器-p 80:80 端口映射 宿主机端口:容器内端口 
[root@node1 ~]# docker run -d -p 80:80 nginx2716e3ec14173a31d8c2168ceceefbbfecec0efe6d611bc710df0bc53748ef0c

3.查看容器运行状态

[root@node1 ~]# docker psCONTAINER ID   IMAGE     COMMAND                  CREATED          STATUS          PORTS                               NAMES2716e3ec1417   nginx     "/docker-entrypoint.…"   26 seconds ago   Up 24 seconds   0.0.0.0:80->80/tcp, :::80->80/tcp   naughty_driscoll

三、测试容器内的应用

在这里插入图片描述

四、检查宿主机端口

[root@node1 ~]# netstat -tunlp |grep 80tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      3807/docker-proxy   tcp6       0      0 :::80                   :::*                    LISTEN      3814/docker-proxy   tcp6       0      0 :::8081                 :::*                    LISTEN      1092/httpd 

五、停止容器

[root@node1 ~]# docker psCONTAINER ID   IMAGE     COMMAND                  CREATED         STATUS         PORTS                               NAMES2716e3ec1417   nginx     "/docker-entrypoint.…"   6 minutes ago   Up 6 minutes   0.0.0.0:80->80/tcp, :::80->80/tcp   naughty_driscoll[root@node1 ~]# docker stop 2716e3ec1417 2716e3ec1417[root@node1 ~]# docker start 2716e3ec1417 2716e3ec1417
