简单启动一个Dokcer容器-02

一、Docker启动容器步骤

(1)搜索镜像
    [root@elk_134 ~]# docker search imagename

(2)拉取镜像
    [root@elk_134 ~]# docker pull imagename

(3)基于Docker启动镜像为容器
    [root@elk_134 ~]# docker run --name "containername" options imagename

二、基于镜像启动一个Nginx容器

(1)搜索nginx镜像，我们使用name为nginx的第一个镜像
    [root@elk_134 ~]# docker search nginx | awk '{print $1}'
    NAME
    nginx
    jwilder/nginx-proxy
    richarvey/nginx-php-fpm
    bitnami/nginx
    linuxserver/nginx
    tiangolo/nginx-rtmp
    nginx/nginx-ingress
    schmunk42/nginx-redirect
    arm64v8/nginx
    nginxdemos/hello
    crunchgeek/nginx-pagespeed
    blacklabelops/nginx
    centos/nginx-18-centos7
    centos/nginx-112-centos7
    webdevops/nginx
    nginxinc/nginx-unprivileged
    sophos/nginx-vts-exporter
    1science/nginx
    nginx/nginx-prometheus-exporter
    mailu/nginx
    travix/nginx
    pebbletech/nginx-proxy
    wodby/nginx
    centos/nginx-110-centos7
    ansibleplaybookbundle/nginx-apb

(2)拉取这个镜像,latest为最新稳定版
    [root@elk_134 ~]# docker pull nginx:latest
    Using default tag: latest
    latest: Pulling from library/nginx
    Digest: sha256:23b4dcdf0d34d4a129755fc6f52e1c6e23bb34ea011b315d87e193033bcd1b68
    Status: Image is up to date for nginx:latest

(3)基于这个nginx镜像启动为容器
    [root@elk_134 ~]# docker run --name "nginx-web1" -d nginx:latest
    7c446cfc8b63cfd4d0e099640a0e7b2a83664d0fe117f1c3dd98bc56a808e206

(4)查看一下这个容器的IP地址，然后使用curl访问一下nginx默认页面
    [root@elk_134 ~]# docker inspect nginx-web1 | grep "IPAddress"                              
    "SecondaryIPAddresses": null,
    "IPAddress": "10.1.1.2",
    "IPAddress": "10.1.1.2",

    [root@elk_134 ~]# curl http://10.1.1.2
