以下命令使用 NGINX 默认的配置来启动一个 Nginx 容器实例：
$ docker run --name runoob-nginx-test -p 8081:80 -d nginx
执行以上命令会生成一串字符串，类似 6dd4380ba70820bd2acc55ed2b326dd8c0ac7c93f68f0067daecad82aef5f938，这个表示容器的 ID，一般可作为日志的文件名。
我们可以使用 docker ps 命令查看容器是否有在运行：
$ docker ps CONTAINER ID IMAGE ... PORTS NAMES 6dd4380ba708 nginx ... 0.0.0.0:8081->80/tcp runoob-nginx-test
PORTS 部分表示端口映射，本地的 8081 端口映射到容器内部的 80 端口。
在浏览器中打开 http://127.0.0.1:8081/，效果如下：
nginx 部署
首先，创建目录 nginx, 用于存放后面的相关东西。
$ mkdir -p ~/nginx/www ~/nginx/logs ~/nginx/conf
拷贝容器内 Nginx 默认配置文件到本地当前目录下的 conf 目录，容器 ID 可以查看 docker ps 命令输入中的第一列：
docker cp 6dd4380ba708:/etc/nginx/nginx.conf ~/nginx/conf
部署命令
$ docker run -d -p 8082:80 --name runoob-nginx-test-web -v ~/nginx/www:/usr/share/nginx/html -v ~/nginx/conf/nginx.conf:/etc/nginx/nginx.conf -v ~/nginx/logs:/var/log/nginx nginx
命令说明：
启动以上命令后进入 ~/nginx/www 目录：
$ cd ~/nginx/www
创建 index.html 文件，内容如下：
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>菜鸟教程(runoob.com)</title> </head> <body> <h1>我的第一个标题</h1> <p>我的第一个段落。</p> </body> </html>
输出结果为：
相关命令
如果要重新载入 NGINX 可以使用以下命令发送 HUP 信号到容器：
$ docker kill -s HUP container-name
重启 NGINX 容器命令：
$ docker restart container-name

Nginx 部署可以查看：Docker 安装 Nginx，一些 Nginx 的配置参考这篇文章。
启动 PHP：
$ docker run --name myphp-fpm -v ~/nginx/www:/www -d php:5.6-fpm
命令说明：
创建 ~/nginx/conf/conf.d 目录：
mkdir ~/nginx/conf/conf.d
在该目录下添加 ~/nginx/conf/conf.d/runoob-test-php.conf 文件，内容如下：
server {
listen 80;
server_name localhost;
location / {
root /usr/share/nginx/html;
index index.html index.htm index.php;
}
error_page 500 502 503 504 /50x.html;

}
location ~ .php$ {
fastcgi_pass php:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /www/$fastcgi_script_name;
include fastcgi_params;
}
}
配置文件说明：

通过Dockerfile创建一个镜像，替换成你自己的名字
runoob@runoob:~/python$ docker build -t python:3.5 .
创建完成后，我们可以在本地的镜像列表里查找到刚刚创建的镜像
runoob@runoob:~/python$ docker images python:3.5 REPOSITORY TAG IMAGE ID CREATED SIZE python 3.5 045767ddf24a 9 days ago 684.1 MB
使用python镜像
在~/python/myapp目录下创建一个 helloworld.py 文件，代码如下：
#!/usr/bin/python
print("Hello, World!");
运行容器
runoob@runoob:~/python$ docker run -v $PWD/myapp:/usr/src/myapp -w /usr/src/myapp python:3.5 python helloworld.py
命令说明：
-v $PWD/myapp:/usr/src/myapp :将主机中当前目录下的myapp挂载到容器的/usr/src/myapp
-w /usr/src/myapp :指定容器的/usr/src/myapp目录为工作目录
python helloworld.py :使用容器的python命令来执行工作目录中的helloworld.py文件
输出结果：
Hello, World!
方法一、docker pull redis:3.2
查找Docker Hub上的redis镜像
runoob@runoob:~/redis$ docker search redis NAME DESCRIPTION STARS OFFICIAL AUTOMATED redis Redis is an open source ... 2321 [OK] sameersbn/redis 32 [OK] torusware/speedus-redis Always updated official ... 29 [OK] bitnami/redis Bitnami Redis Docker Image 22 [OK] anapsix/redis 11MB Redis server image ... 6 [OK] webhippie/redis Docker images for redis 4 [OK] clue/redis-benchmark A minimal docker image t... 3 [OK] williamyeh/redis Redis image for Docker 3 [OK] unblibraries/redis Leverages phusion/baseim... 2 [OK] greytip/redis redis 3.0.3 1 [OK] servivum/redis Redis Docker Image 1 [OK] ...
这里我们拉取官方的镜像,标签为3.2
runoob@runoob:~/redis$ docker pull redis:3.2
等待下载完成后，我们就可以在本地镜像列表里查到REPOSITORY为redis,标签为3.2的镜像。
runoob@runoob:~/redis$ docker images redis REPOSITORY TAG IMAGE ID CREATED SIZE redis 3.2 43c923d57784 2 weeks ago 193.9 MB
方法二、通过 Dockerfile 构建
创建Dockerfile
首先，创建目录redis,用于存放后面的相关东西。
runoob@runoob:~$ mkdir -p ~/redis ~/redis/data
data目录将映射为redis容器配置的/data目录,作为redis数据持久化的存储目录
进入创建的redis目录，创建Dockerfile
FROM debian:jessie # add our user and group first to make sure their IDs get assigned consistently, regardless of whatever dependencies get added RUN groupadd -r redis && useradd -r -g redis redis RUN apt-get update && apt-get install -y --no-install-recommends ca-certificates wget && rm -rf /var/lib/apt/lists/* # grab gosu for easy step-down from root ENV GOSU_VERSION 1.7 RUN set -x && wget -O /usr/local/bin/gosu "https://github.com/tianon/gosu/releases/download/$GOSU_VERSION/gosu-$(dpkg --print-architecture)" && wget -O /usr/local/bin/gosu.asc "https://github.com/tianon/gosu/releases/download/$GOSU_VERSION/gosu-$(dpkg --print-architecture).asc" && export GNUPGHOME="$(mktemp -d)" && gpg --keyserver ha.pool.sks-keyservers.net --recv-keys B42F6819007F00F88E364FD4036A9C25BF357DD4 && gpg --batch --verify /usr/local/bin/gosu.asc /usr/local/bin/gosu && rm -r "$GNUPGHOME" /usr/local/bin/gosu.asc && chmod +x /usr/local/bin/gosu && gosu nobody true ENV REDIS_VERSION 3.2.0 ENV REDIS_DOWNLOAD_URL http://download.redis.io/releases/redis-3.2.0.tar.gz ENV REDIS_DOWNLOAD_SHA1 0c1820931094369c8cc19fc1be62f598bc5961ca # for redis-sentinel see: http://redis.io/topics/sentinel RUN buildDeps='gcc libc6-dev make' && set -x && apt-get update && apt-get install -y $buildDeps --no-install-recommends && rm -rf /var/lib/apt/lists/* && wget -O redis.tar.gz "$REDIS_DOWNLOAD_URL" && echo "$REDIS_DOWNLOAD_SHA1 *redis.tar.gz" | sha1sum -c - && mkdir -p /usr/src/redis && tar -xzf redis.tar.gz -C /usr/src/redis --strip-components=1 && rm redis.tar.gz && make -C /usr/src/redis && make -C /usr/src/redis install && rm -r /usr/src/redis && apt-get purge -y --auto-remove $buildDeps RUN mkdir /data && chown redis:redis /data VOLUME /data WORKDIR /data COPY docker-entrypoint.sh /usr/local/bin/ ENTRYPOINT ["docker-entrypoint.sh"] EXPOSE 6379 CMD [ "redis-server" ]
通过Dockerfile创建一个镜像，替换成你自己的名字
runoob@runoob:~/redis$ docker build -t redis:3.2 .
创建完成后，我们可以在本地的镜像列表里查找到刚刚创建的镜像
runoob@runoob:~/redis$ docker images redis REPOSITORY TAG IMAGE ID CREATED SIZE redis 3.2 43c923d57784 2 weeks ago 193.9 MB
使用redis镜像
运行容器
runoob@runoob:~/redis$ docker run -p 6379:6379 -v $PWD/data:/data -d redis:3.2 redis-server --appendonly yes 43f7a65ec7f8bd64eb1c5d82bc4fb60e5eb31915979c4e7821759aac3b62f330 runoob@runoob:~/redis$
命令说明：
-p 6379:6379 : 将容器的6379端口映射到主机的6379端口
-v $PWD/data:/data : 将主机中当前目录下的data挂载到容器的/data
redis-server --appendonly yes : 在容器执行redis-server启动命令，并打开redis持久化配置
查看容器启动情况
runoob@runoob:~/redis$ docker ps CONTAINER ID IMAGE COMMAND ... PORTS NAMES 43f7a65ec7f8 redis:3.2 "docker-entrypoint.sh" ... 0.0.0.0:6379->6379/tcp agitated_cray
连接、查看容器
使用redis镜像执行redis-cli命令连接到刚启动的容器,主机IP为172.17.0.1
runoob@runoob:~/redis$ docker exec -it 43f7a65ec7f8 redis-cli 172.17.0.1:6379> info # Server redis_version:3.2.0 redis_git_sha1:00000000 redis_git_dirty:0 redis_build_id:f449541256e7d446 redis_mode:standalone os:Linux 4.2.0-16-generic x86_64 arch_bits:64 multiplexing_api:epoll ...
方法一、docker pull httpd
查找Docker Hub上的httpd镜像
runoob@runoob:~/apache$ docker search httpd NAME DESCRIPTION STARS OFFICIAL AUTOMATED httpd The Apache HTTP Server .. 524 [OK] centos/httpd 7 [OK] rgielen/httpd-image-php5 Docker image for Apache... 1 [OK] microwebapps/httpd-frontend Httpd frontend allowing... 1 [OK] lolhens/httpd Apache httpd 2 Server 1 [OK] publici/httpd httpd:latest 0 [OK] publicisworldwide/httpd The Apache httpd webser... 0 [OK] rgielen/httpd-image-simple Docker image for simple... 0 [OK] solsson/httpd Derivatives of the offi... 0 [OK] rgielen/httpd-image-drush Apache HTTPD + Drupal S... 0 [OK] learninglayers/httpd 0 [OK] sohrabkhan/httpd Docker httpd + php5.6 (... 0 [OK] aintohvri/docker-httpd Apache HTTPD Docker ext... 0 [OK] alizarion/httpd httpd on centos with mo... 0 [OK] ...
这里我们拉取官方的镜像
runoob@runoob:~/apache$ docker pull httpd
等待下载完成后，我们就可以在本地镜像列表里查到REPOSITORY为httpd的镜像。
runoob@runoob:~/apache$ docker images httpd REPOSITORY TAG IMAGE ID CREATED SIZE httpd latest da1536b4ef14 23 seconds ago 195.1 MB
方法二、通过 Dockerfile构建
创建Dockerfile
首先，创建目录apache,用于存放后面的相关东西。
runoob@runoob:~$ mkdir -p ~/apache/www ~/apache/logs ~/apache/conf
www目录将映射为apache容器配置的应用程序目录
logs目录将映射为apache容器的日志目录
conf目录里的配置文件将映射为apache容器的配置文件
进入创建的apache目录，创建Dockerfile
FROM debian:jessie # add our user and group first to make sure their IDs get assigned consistently, regardless of whatever dependencies get added #RUN groupadd -r www-data && useradd -r --create-home -g www-data www-data ENV HTTPD_PREFIX /usr/local/apache2 ENV PATH $PATH:$HTTPD_PREFIX/bin RUN mkdir -p "$HTTPD_PREFIX" && chown www-data:www-data "$HTTPD_PREFIX" WORKDIR $HTTPD_PREFIX # install httpd runtime dependencies # https://httpd.apache.org/docs/2.4/install.html#requirements RUN apt-get update && apt-get install -y --no-install-recommends libapr1 libaprutil1 libaprutil1-ldap libapr1-dev libaprutil1-dev libpcre++0 libssl1.0.0 && rm -r /var/lib/apt/lists/* ENV HTTPD_VERSION 2.4.20 ENV HTTPD_BZ2_URL https://www.apache.org/dist/httpd/httpd-$HTTPD_VERSION.tar.bz2 RUN buildDeps=' ca-certificates curl bzip2 gcc libpcre++-dev libssl-dev make ' set -x && apt-get update && apt-get install -y --no-install-recommends $buildDeps && rm -r /var/lib/apt/lists/* && curl -fSL "$HTTPD_BZ2_URL" -o httpd.tar.bz2 && curl -fSL "$HTTPD_BZ2_URL.asc" -o httpd.tar.bz2.asc # see https://httpd.apache.org/download.cgi#verify && export GNUPGHOME="$(mktemp -d)" && gpg --keyserver ha.pool.sks-keyservers.net --recv-keys A93D62ECC3C8EA12DB220EC934EA76E6791485A8 && gpg --batch --verify httpd.tar.bz2.asc httpd.tar.bz2 && rm -r "$GNUPGHOME" httpd.tar.bz2.asc && mkdir -p src && tar -xvf httpd.tar.bz2 -C src --strip-components=1 && rm httpd.tar.bz2 && cd src && ./configure --prefix="$HTTPD_PREFIX" --enable-mods-shared=reallyall && make -j"$(nproc)" && make install && cd .. && rm -r src && sed -ri -e 's!^(s*CustomLog)s+S+!1 /proc/self/fd/1!g' -e 's!^(s*ErrorLog)s+S+!1 /proc/self/fd/2!g' "$HTTPD_PREFIX/conf/httpd.conf" && apt-get purge -y --auto-remove $buildDeps COPY httpd-foreground /usr/local/bin/ EXPOSE 80 CMD ["httpd-foreground"]
Dockerfile文件中 COPY httpd-foreground /usr/local/bin/ 是将当前目录下的httpd-foreground拷贝到镜像里，作为httpd服务的启动脚本，所以我们要在本地创建一个脚本文件httpd-foreground
#!/bin/bash set -e # Apache gets grumpy about PID files pre-existing rm -f /usr/local/apache2/logs/httpd.pid exec httpd -DFOREGROUND
赋予httpd-foreground文件可执行权限
runoob@runoob:~/apache$ chmod +x httpd-foreground
通过Dockerfile创建一个镜像，替换成你自己的名字
runoob@runoob:~/apache$ docker build -t httpd .
创建完成后，我们可以在本地的镜像列表里查找到刚刚创建的镜像
runoob@runoob:~/apache$ docker images httpd REPOSITORY TAG IMAGE ID CREATED SIZE httpd latest da1536b4ef14 23 seconds ago 195.1 MB
使用apache镜像
运行容器
docker run -p 80:80 -v $PWD/www/:/usr/local/apache2/htdocs/ -v $PWD/conf/httpd.conf:/usr/local/apache2/conf/httpd.conf -v $PWD/logs/:/usr/local/apache2/logs/ -d httpd
命令说明：
-p 80:80 :将容器的80端口映射到主机的80端口
-v $PWD/www/:/usr/local/apache2/htdocs/ :将主机中当前目录下的www目录挂载到容器的/usr/local/apache2/htdocs/
-v $PWD/conf/httpd.conf:/usr/local/apache2/conf/httpd.conf :将主机中当前目录下的conf/httpd.conf文件挂载到容器的/usr/local/apache2/conf/httpd.conf
-v $PWD/logs/:/usr/local/apache2/logs/ :将主机中当前目录下的logs目录挂载到容器的/usr/local/apache2/logs/
查看容器启动情况
